4. Manufacturers supply the supporting accessories for the mud slurry pump manufacturers for many years , with rich experiences, and have the reliable product quality, good reputation in the industry.

A Mud Pump Cylinder liner flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet Mud Pump Cylinder liner flange). A blind Mud Pump Cylinder liner flange is a plate for covering or closing the end of a pipe. A Mud Pump Cylinder liner flange joint is a connection of pipes, where the connecting pieces have Mud Pump Cylinder liner flanges by which the parts are bolted together.

Although the word Mud Pump Cylinder liner flange generally refers to the actual raised rim or lip of a fitting, many Mud Pump Cylinder liner flanged plumbing fittings are themselves known as "Mud Pump Cylinder liner flanges":

Common Mud Pump Cylinder liner flanges used in plumbing are the Surrey Mud Pump Cylinder liner flange or Danzey Mud Pump Cylinder liner flange, York Mud Pump Cylinder liner flange, Sussex Mud Pump Cylinder liner flange and Essex Mud Pump Cylinder liner flange. Surrey and York Mud Pump Cylinder liner flanges fit to the top of the hot water tank allowing all the water to be taken without disturbance to the tank. They are often used to ensure an even flow of water to showers. An Essex Mud Pump Cylinder liner flange requires a hole to be drilled in the side of the tank.

There is also a Warix Mud Pump Cylinder liner flange which is the same as a York Mud Pump Cylinder liner flange but the shower output is on the top of the Mud Pump Cylinder liner flange and the vent on the side. The York and Warix Mud Pump Cylinder liner flange have female adapters so that they fit onto a male tank, whereas the Surrey Mud Pump Cylinder liner flange connects to a female tank.

Fig 1 F－1300/1600 mud pump overall dimensions 1.2 Installation of New Pump F-1300/1600 mud pump has been completely assembled and tested under pressure before being shipped from factory, the lubricating oil has been drained from power end as well. Before putting the pump into service, the measures and operations must be checked andperformed: In order to prevent personal injury during the operation of any maintenance or inspection procedures, this equipment must be shut down and not running, and all safeguards on prime movers, drives, etc, must be installed and in the safe position. The skid of BOMCO F-1300/1600 mud pump can adapt to all kinds mounted type, but 4

Figure 2 1.2.1 Land Installation In land installations, 8 pieces of shim plate (76mm×305mm) should be laid down along the length of pump skid indicated in Fig.2. The boards should be 300mm wider than the width of the pump skid beams. Wet or marshland may require a more stable foundation. 1.2.2 Permanent Installation Install the mud pump on drilling ship, structural base or construction of drilling platform, the skid should be shimed and fixed with bolts to prevent twisting or distorting of pump frame. The pump skids must sit solid on all shim points when bolts loose. If the pumps are installed on drilling ship, the skids are gerenally bolted to T-beams, the shims should be put properly according to Fig, 2 and 3 to prevent twist or distortion. All the shims should be wider the skid beam flanges and have a minimum length of 12″ (305mm).

If the power unit, transmission and pump skid are mounted integrally, the mud pump package must be installed on skid with T beam fitting with stop block rather than bolts to hold it in place. This way will allow the pump to “float” and minimize the deformation possibility of pump frame due to the deformation of ship platform or drilling platform. 1.2.3 Installation of transmission device The transmission between the mud pumps and the power source are V-belts or multistrand chain, should be installed accurately to assure maximum service life and the least shutdown time due to transmitting failures. When installing the drive sheave of sprocket, make sure all grease or rust preventative is removed from the shaft and the bore of the drive. Remove all burrs or rough spots from the shaft, key, and keyway. Fit key to the keyways in both the shaft and drive and install key into shaft keyway. Coat pinion shaft with a light coating of anti-seize compound or light oil and install the drive sheave or sprocket hub,tighten hub bolts as indicated below: When a wrench or length of pipe is used to increase leverage in tightening draw-up bolts, it is imperative to adhere to the wrench torque values given in the chart below. This adherence is important, because in mounting the hub, the tightening force on the bolts is multiplied many times by the wedging action of the tapered surface. This action compresses the hub for a snug fit on the shaft. If the bolt-tightening forces are extreme, bursting pressure is created in the hub of the mounted pulley; this pressure may cause the pulley to crack. The hub bolts should always be tightened alternately and progressively. Wrench Torque N·m 810

Note：N=0.1kgf 1.2.3.1 V-Belt Drives 1） Check sheaves groove condition Before installing, check sheave grooves for wear. Worn or rounded grooves will destroy V-belts rapidly. The sidewalls must be straight. Sheave grooves must be free of dirt, rust or other extrusions, which could damage the V-belts. 2）Check the sheave alignment 3） Adjust V-belt for proper tension Adjust the belt tension by moving the sheaves apart until all of the sag has just been

eliminated from the tight side of the belt and some of the belts on the slack side. Then increase the given center distance. For example: on 2540mm(100″) Center distance, after adjusted center distance then increase additional 13mm(1/2″). On 3180mm (150″) center distance, after adjusted center distance then increase additional 19.5mm (3/4″). Do not obtain belt tension by picking up end of pump and allowing belts to tighten under weight of pump as end is being lowered to the ground. 1.2.3.2 Chain drives 1）Installation Proper installation and maintenance of the sprocket and chain drives are essential if good service life is to be obtained. Since many factors, such as chain width, center distances, speeds, and loads must be considered when determining the allowable tolerance for sprocket alignment; no good “rule of thumb” can be applied. The chain alignment must simply be held as nearly perfect as possible. A more precise alignment can be made by stretching two steel wires (piano wire) along one face of the two sprockets, one above and one below the centerline, and moving one of the sprockets until the wires touch at four points. This will determine that the centerlines of the drives are parallel and the faces of the sprockets are square. 2） Drive chain lubrication The pump drive chain lubrication system on the majority of BS pumps is an independent system having its own oil pump, reservoir, and drive. Fill chain case to the indicated lever. SAE number of lubrication oil is refer to 《Choose of BOMCO product lubrication oil》 For temperature below -18℃ （ 0°F ） , consult a reputable lubrication dealer for recommendations. Refer to general lubrication bulletin for approved lubricants and additional specifications Since this is an independent system, it will require the same maintenance or service attention employed on any other piece of machinery, including: ——Daily check of oil lever. ——Daily check on condition of oil. ——Frequent check on oil pressure. （5～15PSI，that is 0.035～0.103MPa） ——Volume of oil being applied to chain. ——Condition of nozzles in spray tube. ——Condition of oil pump drive( V-belts or chain) Note： ① Oil pressure may be adjusted with pressure relief adjusting screw on rear of 7

the pump housing. ②Pressure drops or increase may also indicate suction and discharge filter screens need cleaning. 1.3 Suction system requirements Individual installation conditions will dictate the design of suction system. The suction of F-series pumps must have a positive head(pressure) for satisfactory performance. The optimum suction manifold pressure is 0.14 ～ 0.21MPa(20 ～ 30psi) for maximum volumetric is efficiency and expendable parts life. This head pressure is best supplied by a 6×8 centrifugal pump with 45Kw、1450rpm electric motor. This type of drive requires a device to automatically start and stop the centrifugal pump motor simultaneously with the triplex pump. On DC electric powered rigs a signal can usually be supplied from the DC control panel to energize a magnetic starter. The charging pump can also be belt driven from the triplex pinion shaft. The suction lines should be piped with valve arrangements so the charging pump can be by-passed so operation can be contined in event if charging pump failure or for maintenance. Operation without a charging pump can be improved by replacing the suction valve springs with a weaker spring. Suction desurgers are a very effective aid for complete filling of the liners and dampening pulsations in the suction line which results in a smoother flow in the discharge line. Caution: Do not pipe the return line from the shear relief valve back into the suction system as a relief valve operation will cause a sudden pressure rise in the system vastly greater than the system pressure ratings, resulting in damage to manifold,suction desurger and centrifugal pump. 1.4 Preparation of power end F-series pumps have been completely assembled and test operated before being shipped to the field. Unless otherwise instructed, the lubrication is drained from the power end, and the expendables are removed from the fluid end

Before operating the pump, the following must be performed or checked. 1.4.1 Power end lubrication Before installing lubricant, open inspection door in cover and check oil reservoir for possible accumulation of condensation, etc, and drain and flush by removing the pipe plugs on each side of the pump. Refer Item 2.Fig.7. Add the proper type and quantity of

lubrication in the power end. Refer to lubrication plate on pump frame for type and quantity required. Recheck oil level after pump has operated for a period of 15 minutes. Shut pump down and allow approximately five minutes for the oil level to equalize, Check at oil level gauge, Item 1, Fig 7.It is usually necessary for 3 gallons (10L) of oil to be added due to a certain amount being retained in the crosshead area and frame cavities. 1.4.2 Installation of Crosshead Extension Rods and Diaphragm Stuffing Box

Fig. 4 (1) diaphragm stuffing box and mud apron (2) Bolt (3) Shim (5) spring (6) double-lip oil seal (7)oil seal ring (8)O-ring (9) Locking spring (10)bolt (11)bolt

With reference to Figure 4, remove the diaphragm stuffing box (1) and rotate pump so that crosshead is at the front of the stroke, thoroughly clean the front of the crosshead and the face of the crosshead extension rod. Insert alignment boss on crosshead extension rod into the crosshead bore and tighten the retainer bolts (2) to the following torque, 350~370ft.lbs (475~500N.m), at last tightened with iron wire. Thoroughly clean mud apron and the face of frame, on the “A” place Fig. 4 is with the shim ③and tighten bolt ⑩to the following torque, 90~120ft.lbs(120~160N.m) Throughly clean bore and face of diaphragm stuffing box plate. Clean OD and flange of diaphragm stuffing box. Coat OD of diaphragm stuffing box with light oil and installO-ring seal (4), insert diaphragm stuffing box in plate bore and tighten capscrews to the following torque: 16～24N·m(12～18ft. lbs). The diaphragm stuffing box packing assembly consists of two double lip oil seal (6), an 9

oil seal ring (7), an O-ring (12) O-ring (8) and a lock spring (9). Install the assembly as follows: A： 1) Remove pressure spring ⑤ from double lip oil seal ⑥ and place seal in the outer position on the crosshead extension rod, with lip toward power end. Replace the pressure spring ⑤ in the seal lip and slide the seal into position in the stuffing box. 2) Install the O-ring 12 ○ into Oil seal ring ⑦. Insert O-ring 12 ○ and Oil seal ring ⑦ over rod and slide it into stuffing box bore. 3) Install the O-ring ⑧ in groove in stuffing box bore. 4) Install the double lip oil seal on left and right side of Figure 4 according to step 1). Caution: The double lip oil seal can be used in the inner of power end, position to replace the single lip seal, But Do Not use the single lip seal in the oyter position. 5) Install the locking spring ⑨. B： 1) Remove stuffing box ① from pump frame. Install double lip oil seal ⑥, O-ring 12, ○ O-ring 8 in stuffing box ①, then install O-ring ④ on cylndrical surface of stuffing box ①. Install guiding sleeve(tools) in front of extension rod as Figure 4, Coat extension rod and outer surface of guiding sleeve with light oil. Install stuffing box assembly on extension rod through guiding sleeve and push it to the right position, install it on mud apron with spring washer and bolt 11. ○ Note: Caution must be exercised to assure the pressure spring ⑤ doesn’t slip out of the groove in the oil seal lip, as severe scoring of crosshead extension rod can occur. Coat extension rod with light oil to facilitate installation of stuffing box assembly. 1.5 Spray Pump Assembly Spray pump assembly consists of spray pump, water tank and spray nozzle etc. it is used for flushing and cooling piston and linear during pump operated. Proper attention must be paid at all times to assure adequate cooling fluid is being applied to the piston and liner assembly. Stoppage of the cooling fluid will result in almost instant failure of the piston rubbers and possibly extensive damage to the liner bore. Stationary spray type have been used on F-series pumps Ref. Fig 5.It consists of a fixture (1), a steel pipe (2) and a spray nozzle (3), it make cooling fluid spray to piston and linear. Adjust cooling water supply to the manifold and inspect spray nozzle

to the manifold on the frame. Adjust regulating valve (Item 4 Fig .7) to apply as much water as possible to the liners without splashing back on the crosshead extension rods and diaphragm stuffing box plate. If water is allowed to splash on the crosshead extension rods, some of the water will work back into the power end to contaminate the lubrication oil. The cooling fluid is returned from the crosshead extension rod compartment to the setting chamber, and as the fluid overflows through the filter screen between the two sections of the tank, the solids are allowed to settle out. The filter screen will catch much of the foreign material floating in the fluid. With reference to Fig .6. Check condition of the cooling fluid at frequent intervals and CLEAN and FLUSH reservoir as required and replace the cooling fluid. Increasing Sand grain in Contaminated fluid will cause premature liner and piston wears

tank Note: All of the parts in this fluid end assembly are designed with metal to metal seating to alleviate friction wear from breathing action encountered in modern high pressure pump operation. For this reason it is essential that all parts be clean and free of rust, nicks and burrs before being assembled.

Note: It’s forbidden to coat grease or oil on exterior conical surface of valve seat and interior conical surface of valve seat bore. Make sure all valve seat bores are VERY CLEAN AND DRY (free of dirt, grease, anti-rust compound, etc). Thoroughly clean and dry the valve seats and installs suction and discharge valve seats into the valve pot bores. Drive seats firmly into place with a bar and hammer to ensure contact closely. Install valves and springs and the other parts.

1.6.2 Liners Installs wear plate seal (1) in counter bore of fluid end (see Fig. 8). Slide wear plate (2) over studs until it seats against fluid end. Install liner flange (3) over studs with the starting thread at the 5 o’clock position and tighten bolts to 470~510ft.lbs (640~690N.m) torque. Note: Placing the starting thread at 5 o’clock position makes engaging the liner lock threads much easier. Place liner seal (4) in counter bore of wear plate (2). Apply thin coat of grease to ID of liner lock (5) and slide over rear of liner (6). Install two-piece liner lock ring (7) in liner groove and O-ring to hold them in position. Slide liner-handling tool over liner up against liner lock ring and tighten setscrew to secure it in place. Hoist liner assembly into position with jib hoist (for lifting liner, the maxmum hoisting weight is 500KG). Apply liberal coat of grease to liner lock threads. Align the starting thread of the liner lock (5) to the 7 o’clock position and insert the liner into the liner thread ring (3) screw liner lock in until liner seats in position. Tighten with sledgehammer on hammer lugs. 1.6.3 Piston rod Clean piston (9) and piston rod (8), making sure they are free of nicks and burrs. Install “O” ring seal (10) in groove in piston head. Slide piston head (9) on rod while observing that O-ring does not fall out of groove. Tighten piston rod nut (11) to 1625~2165 N.m (1200~1600ft.lbs.) Coating grease with. Liner I.D. and piston O.D .Check ends of piston rod and extension rod to be sure they are clean and free of burrs. Insert piston rod into liner through cylinder head opening holding piston rod centered at the rear of the liner. Drive the piston into the liner with a driving tool or a piece of hardwood and sledgehammer. Use caution as the piston rod approaches the crosshead extension rod that the dowel on the end of the piston rod is not damaged. The piston rod must be supported and the dowel guided into the pilot bore. 1.6.4 Piston rod clamps The piston rod clamps are machined as one piece and then sawed in half. The two pieces are with matching numbers on each half and connected by chain. The two pieces with the same matching numbers should always be kept together as a set. Install the clamp around the rod end flanges. Tighten bolt to the following torque values: 330N.m (245ft.ls). Before the clamps are installed, mud apron (19) should be installed on the end of crosshead rod. 14

When rods and rod clamp are new a gap in excess of 5.5mm could be present between the two halves of the clamp, this is satisfactory provided the faces of the rods are seating metal to metal. As wear occurs, the halves will pull closer together. Clamping action will be lost when a gap no longer exists. At this time clamps must be replaced. Install splash plate on rear of liner. 1.6.5 Lower valve Guide and Cylinder Head Insert the lower valve guide (13) through the alignment ring and position the guide over the valve stem. Start the lock plate (14) and draw it down, compressing the valve spring and seating the valve guide in the tapered slot.

Before assembly thoroughly clean ring joint groove, install ring (4) and tighten the flange bolts (5) to 1625-2165N.m（1200-1600ft. lbs）torque. To assure uniform make-up of the ring joint connection, tighten the nuts in a criss-cross order The shear relief valve (3) is installed on the discharge manifold for the purpose of protecting the pump from excessively high-pressure overloads. The relief valve must be installed so that is will be directly exposed to the mud. DO NOT PUT ANY TYPE OF SHUT OFF VALAE between the relief valve and the manifold. Pipe the discharge side of the relief valve directly into the mud pit with as few turns in the line as possible. If the turn must be made, the elbow should be over120º. IT IS NOT RECOMMENDED for the discharge side of the relief valve to be piped into the suction line of the pump. The mounting for KB-75 pulsation dampener (1) is a flange with R-39 ring gasket. Before installing dampener, thoroughly clean ring groove and ring, and after setting dampener into place, tighten the nut (8)to 950-1265N·m （700-935ft. lbs） torque. to insure uniform make-up, tighten nuts in a criss-cross order. At each side of discharge crossis flange with seal ring ⑨R-27. Before installation, 16

thoroughly clean seal ring and groove, the torque of connecting bolt and nut is 495-660N·m（365-490 ft. lbs） in a criss-cross order . Precharge dampener before starting up pump. Dampener should be charged with nitrogen or air. (with reference this instruction manual“dampener”)

1.7 Dampener Assembly Proper installation and usage of dampener can availably reduce the pressure fluctuation of discharge system therefore obtaining more smooth fluid. For the sake of acquiring long life span of dampener, usually make pressure of pump and Precharge pressure of bladder to keep the suggestion proportion. (Precharge pressure should not be more than 2/3 of the pump discharge pressure, or a maximum of 4.5Mpa.） 1.7.1

Pressure must be changed if the liner size changed.（Refer to Section 1.1.2 function parameter）. Wire, welding rod or other material are strictly forbidden, otherwise the valve pressure will be affected and may cause an acc a reverse accident. 2

Proper lubrication of the moving parts in any piece of machinery is the most important single factor affecting its ultimate life. To obtain maximum trouble-free service life from the power end, it is necessary to perform routine maintenance care and inspections to insure the proper amount of clean lubricant is being provided. 2.1 Minimum operating speeds The F-Series pumps utilizethe controlled flow oil bath splash and pressure system to 19

lubricate the entire power end. The type of pressure system provided in each individual pump will govern the minimum SPM at which the pump can be operated. As shown in Fig. 13, F－1300/1600 mud pump can be operated at 25 SPM. Provided(at a pressure of 0.035Mpa).

Fig. 13 Note: The pressure lubricating system can be provided with an externally mounted oil pump driven through V-belts or internally mounted oil pump driven from the main gear. When an internally mounted oil pump is used, the direction of rotation of the pinion shaft must be as shown in Fig. 13. 2.2 Controlled Flow Splash System The controlled flow splash lubrication system is the same for all F-Series pumps, regardless of the type of oil pump drive provided for the pressure system. In the controlled flow splash system, the main gear picks oil up from the reservoir, and when the teeth mesh with the pinion, the oil is displaced into various troughs and compartments in the frame. With reference to Figure 15, the oil thrown into oil trough (7) is directed through the oil tube (8) to the two pinion bearings Oil passage from the of the crosshead guide compartment to the crosshead bearing is shown in Figure 14, Oil accumulates in the compartment over the crossheads. The oil runs through the nipple (1) into the crosshead retainer to the oil passages (5) and on to the crosshead pin bearing. As noted, the duplicate set of oil passages (5) in the crosshead pin permits the crosshead pins to be rotated without having to give attention to hole alignment. This permits the installation of crosshead pins from either direction.

2.3 Pressure Lubrication System The pressure lubrication system, incorporating the oil pump for the F-series pumps, is shown in Figure 15: In this system, filtered oil is supplied to the pump through the suction filter (1) and is discharged from the pump into the manifold block (2) and nozzle (3A). Oil is distributed to the main bearing oil line (4) and the crosshead compartment manifold block (4A) located above the crosshead compartment. The crosshead compartment manifold block (4A) distributes oil to the crosshead, crosshead bearings and extension rods. A pressure gauge (5) is mounted on the back wall of the frame to show oil pressure being maintained in the manifold block. The oil pressure will, of course, vary with the speed of the main pump, however if a sudden pressure drop or increase occurs, refer to the section on maintenance of lubrication system for possible cause. A pressure relief valve (6) is mounted to the manifold block (2) to keep excess pressure from damaging oil pump and drive. The relief valve work pressure should be 0.27Mpa (40 PSI). When installing the internally mounted oil pump(item 9,Fig 15), position pump so that the back face of the drive gear is flush and parallel with the edge of the main gear, and

A typical layout for the pinion shaft driven oil pump is shown in Fig. 16. The oil pump (1) is piped into the oil system through the suction and pressure connections on the bottom inside wall of the power frame. Do not adjust V-belt drive (2) too tight. Over tightening can cause premature failure of the pump. To prevent possible injury, always install guard (3) over V-belts before putting pump into service.

2.4 Maintenance of Lubrication System Adequate lubrication of the moving parts is, as stated, the most important single factor affecting the ultimate service life of the pump, care and maintenance of the system is the sole responsibility of the operator or crew to which it has been assigned, and the extent to which this is applied will determine the amount of trouble – free service life that will be obtained. 2.4.1 Lubrication specifications The lubricant recommendations is shown on the nameplate on the side of the pump, also can refer to 《BOMCO lubrication oil selected guidebook》. All these materials are the result of extensive long-term field tests and can validate to wear away (include gear, bearing and guild cross head). Substitutions should be made only in extreme emergencies. 2.4.2 Oil reservoir capacity: Oil reservoir capacity: 379L （100 U.S. Gallons） 2.4.3 Routine check Once each tour, check and maintain oil lever at full mark on the bayonet gauge. Pump must be shut down and allowed to stand idle for approximately five minute-to allow oil lever to equalize. Once each six month, or more often if oil becomes contaminated with abrasive particles or corrosive compounds, drain and flush the oil reservoir and pour new lubricant. Oil drains are located on eighter side of the pump frame. During the flushing procedure, thoroughly clean the oil troughs and the compartment in top of the crosshead guide. Also clean or replace the filter element in the air breather cap and clean suction screen. Remove covers from settling chamber and purge out contaminants before adding new oil. Routine inspection on condition of oil should be made as condensation of moisture in the air, instrusion of mud, water or dirt, can necessitate a more frequent oil change. A settling chamber is located in the forward area of the power end floor, The contamination in the oil splashed into this area should be drained from clean out covers. Once each month, remove clean out covers on both sides of pump to drain contaminated oil from settling chamber. Approximately 15-gallons of oil will be lost; replenish the main reservoir to compensate for amount drained out. Once each week, remove one of the lower 1/2” capscrews that secure the clean out cover to the frame to drain off water condensate.

Once each tour, check oil lever in main reservoir. Maintain at full mark on dipstick to the manifold block. If loss of pressure occurs, check for: —— Clogged suction screen —— low oil lever —— slipping V-belt drive —— Broken or loose connections —— Damaged or worn oil pump —— Defective relief valve For an abnormal increase in oil pressure, check for: —— Plugged oil lines —— Contamination causing oil to be viscous —— Relief valve inoperative —— Defective gauge —— Other conditions 3

Check the suction hose of the gear pump to insure it is not damaged and staved. 3.1.4 Suctiong Filter Check condition of suction filter.Clean and repace as necessary. 3.1.5 Main Bearing Cover Remove the main bearing cover and check the tightness of the main bearing 24

increase ,immediately contact the manufacturer for a thorough inspection of the gear. 3.1.7 Crosshead Pin Bolts and Crosshead Guides Remove cover and check condition of the crosshead pin bolts and safety wires（Remove the back cover when check the center crosshead pin blots, meantime locate the eccentric strap at the back dead position）.Tighten crosshead bolts 24×70（Fig 14 item 3），torque is 225～240N·m (165～175ft. lbs) DO NOT EXCEED THE ABOVE VALUES, USE TORQUE WRENCH. If the crosshead or guide shows abnormal wear or scoring, replace immediately as the metal particles can cause damage to the bearings etc.Excess wear can also cause rapid wear to the piston and liners. 3.1.8 Lubrication and Reservoir Check condition of the oil and cleanliness of the oil reservoir.Service oil system as described in the lubrication section of this manual. 3.2 Roller Bearings F series mud pump use roller bearings which is a precisely built machine whthin itself; therefore, careful handing is required in order to obtain the long service load carring characteristics associated with anti-friction

the roller assemblies of each bearing must be kept together, and reinstalled exactly as they came off. It is always necessary to completely replace any roller bearing that fails,enve though 25

than three minutes.Do not heat the bearings with a torch unless it it the only possible means available.When it is necessary to use a torch, it should be used only by an experienced welder of machnic.Hold the torch at least 150mm(6″)away from the bearing and keep the torch moving at all times.Heat the bearing only until it is hot to the torch. Use a Tempil-Stic. DO NOT OVERHEAT THE BEARING. Overheating draws the temper of the metal and makes the bearing soft. Once the heated bearing is in place on the shaft, hold it in place until it cools. NEVER USE WATER OR ANY OTHER LIQUID TO COOL A HOT BEARING. Rapid cooling will cause the surfaces of the reaces and rollers to “check”or crack and the bearing will fail immediately. Never strike a roller bearing with a steel hammer. If the bearing must be driven into position,use wood or a soft hammer and stike lightly. Always lubricate the shaft or housing before installing the bearing,preferably with clean white lead, thinned with light oil, or anti-seize compound. After removing a new bearing form the box or wrapping,protect it from dirt and other foreign matter at all times.Before installing a bearing, clean it with kerosene or othe solvent.

Note： T-Shrink Range，L-Space Range The pinion is an intergral part of the shaft, leaving only the installation of the bearings and wear ring to complete the assembly. (Refer to Fig 17)。 The running clearances of the bearins are predetermined by their preision fit to the shaft and the bearing carrier. When perfoming maintenance or overhaul, makd sure the fits show in Chart II are obtained. Installation of pinion shaft assembly in pump: 1）Insure pinion bearing carrier gasket ①and oil seal carrier gasket②are in place and in good condition. 2）Installation the pinion bearing carrier③ and the oil seal carrier④, make sure the oil collectin box ⑦ at a right place to positon oil throughs and align drain holes. 3）Remove burrs,dents or gouges from the OD of the oil seal spacer before sliding the oil seal carrier into place.Exercise care when sliding lip of seal over end of shaft to prevent it from being damaged by the sharp edge of the keyway. Also pay particular attention to insure oil seal lip IS NOT TURNED UNDER by edge of spacer when sliding seal onto the spacer. 4）Tighten pinion bearing carrier bolts ⑥to the torque: 110～215N.m (80～160ft.lbs) 27

in the three eccentric straps. The outer race retainer is equipped with oil scoop and must be installed with SCOOP DOWN(90° to horizontal centerline of the eccentric strap). Tighten retainer bolts ④ to torque 75 N·m(55ft.lbs), and safety wire heads. Note: The inner race, outer race and roller of the eccentric bearings are matched and must not be intermixed. 3) Install the outer race of crosshead bearings in the three eccentric straps.It is preferred that the outer race

a deep freeze until it can be inserted into the bore.Under emergency circumstances,the outer race assembly can be installed by using a large torch and heating the “eye” o f the eccentric strap. DO NOT EXCEED 149℃（300℉）-use a tempilstik- and DO NOT USE WATER TO COOL THE STRAP. Note: The inner and outer race of the crosshead bearings are matched and should not be intermixed. 4) Install the inner race of the crosshead bearings on the crosshead pin and mark according to their respective eccentric strap positions. (Such as 1 、 2 、 3 or left, middle,right).Remove all nicks and burrs before shrinking race into place.Fit tolerance, refer to Chart 3，position H. 5) Install the inner race of the center eccentric bearing on shaft.Slide center eccentric strap into position and install inner bearing retainer，Tighten the retainer bolts（8A），the torque is 60～90 N·m (44～66 ft.lbs)，and safety wire. 6) Install snap ring in the groove on right eccentric bearing and shrink inner race of eccentice bearing on shaft.After sliding the righr eccentric strap into positon, install the

inner race retainer 14 ○ .Tighten the retainer bolt⑧, the torque is60 ～ 90N·m (44 ～ 66ft.lbs). 7) Install left eccentric bearing,eccentric strap etc.（Refer to item 6）. 8) Place main bearings⑨ into the main bearing carriers(10 RH and 11 LH），and install outer race retainer12. ○ Tighten bolts15 ○ to the torque 60～90N·m (44～66ft. lbs) 9) After inatalling the two main bearings16，shrink ○ main bearings⑨ on each end of the shaft.Install inner race retainer 17 ○ and retainer bolts 18 ○ , tighten the bolts to the torque60～90N·m (44～66ft. lbs) 3.5 INSTALLING CRANKSHAFT ASSEMBLY IN FRAME In order to obtain a more precision fir between the main bearing housing and the frame bore on F-series pumps, the installation procedure outlined below are to be followed: （Refer to Fig 19）。 1) Place a piece of wood between eye of eccentric strap and crosshead guide(Fig 20）， to protect guide from scoring or gouging as the straps are slidjing into position. 2) Rotate the main bearing carrier so that the two flat spots

with the main bearing bolt holes,and slowly lower the crankshaft into position.（The flat spot provides clearance for the main bearing bolts）. 3) After palcing crankshaft in the frame, and before installing the main bearing cover②, check the rollers in the main bearings to assure that each row of rollers in each bearing is equally loaded. The details are as following:twang each row of rollers by hand, because action of gravity, it is normal if there are 4-6 rollers lock. But it is not allowed that some one row of roller cab be twanged totally. Besides, axial clearances should be almost same on both side faces of outer ring in floating bearing. After checking qualified, install main bearing cover ②.

4) Install and shim main bearing cover to obtain 0.06-0.10mm（0.0024-0.0040in）clamp or preload on the main bearing carrier.This preload is obtained by placing the correct 30

Note ： Machining tolerance make it necessary to determine individual shim requirements for each main bearing cover. 5) Install main bearing cover with the correct amount of shims as determined above, and tighten main bearing bolts to torque values shown in Chart IV . 6) Again check inner and outer row of rollers on each bearing as previously outlined to assure equal loading is stil present on each bearing.

3.6 Installation of Crosshead Guides 1） Thoroughly clean all dirt or contamination and remove all burrs or rough edges from both sides of the guides and the frame bore. 2）If old guides are to be reused,inspect the wear or scoring on the mating surfaces.If necessary, they should be changed. Note: For

interchangeable.The lower guide allows the crosshead to locate on the centerline of the frame.And the upper guide is machined to afford proper clearance between crosshead and upper guide.The upper guide is thinner and has a big chamfer.There is a oil hole in the middle of upper guide. 3） Install lower and upper guide, tighten the bolts to torque: 205 ～270N.m (150～200ft. lbs)。 4） Check mating

a 0.05mm (0.002in)feeler gauge between the two parts. 3.7 Installation of Crosshead The crossheads are installed through the front (fluid end) end or back end of the crosshead guide. When installing crossheads, observe the following precautions:

Fig. 20 1) Thoroughly clean all dirt or contamination and remove all burs or rough edge from the OD of the crosshead, crosshead pin bores, and inner bore of the crosshead guide.Dry crosshead pin bore so that taper bore connection will make up metal to metal(See note）. 2) Positiong “eye” of eccentric strap at the opening in the side of the crosshead guide.Block eccentric strap so that crosshead will clear the “eye” as it is sliding into position to where the crosshead pin holes are in alignment（Fig 20）. 3) Install the left hand crosshead first, then rotating crankshaft assembly to let the “eye”of center eccentric strap into the crosshead. Meantime, the “eye”of right hand eccentric strap slides back, remove diaphragm plate (Fig 21 item 1).Push the right hand crosshead forwards into the front end of the frame.In that case, there will be enough space for installing the center crosshead.After that, install the right crosshead.

pump and rotated 180°to provide a smooth surface for the bottom of crosshead.The center crosshead can also be rotated 180°and install the crosshead pin in the opposite side.Install the crosshead pin retainer ②before install the crosshead pin into the crosshead. 4) Install crosshead pin retainer② and retainer bolts③, and rotate pin until the four crosshead bolt holes are in aligenment.Install fout bolts and make up hand tight.Reger to Fig 21.Make sure the oil slot on the retainer up.

In order for the pistons to run normally in the liners, the crosshead must travel in a straight line along the horizontal centerline of the frame bore. To check and adjust crosshead alignment, proceed as follows: 1) Remove diaphragm stuffing box from the diaphragm plate, (Fig, 21). Do not remove the plate. 2) Position crosshead at the extreme front of its stroke. With inside calipers or telescoping gauges, accurately measure the distance from the diaphragm plate bore to the crosshead extension rod at the top and bottom. Compare the two measurements to determine the position of the rod relative to the centerline of the bore. 3) Rotate pump to extreme rear of stroke and take measurement again at the same place. Compare these measurements to the ones taken at the front of the stroke to determine if crosshead is running horizontally. 4) If the centerline of the extension rod is more than 0.38mm (0.015″) low in the diaphragm plate bore, shims should be inserted under the lower guide to bring the extension rod back to center, provided there is ample clearance between the top of crosshead and upper crosshead guide. It is normal for the lower guide to wear more at the rear due to heavier loading at this point because of the angle of the eccentric strap. It is permissible to shim the guides on a taper if the guide can seat on the frame firmly. Do not shim guides to less than 0.50mm (0.020″) clearance between upper guide and crosshead. The large crosshead clearances are acceptable due to 34

characteristics of triplex pump , the crosshead pressure is always loaded on the lower guide when the pump works postively. Note: If the mud pump must run in reverse situation.The clearance between the upper guide and crosshead should be within the range 0.25 ～ 0.40mm （0.010-0.016in） 5)

For many years, the fluid end of a pump was considered a non-wearing part which did not cause any concern other than possible infrequent repairs or replacements resulting from fluid cuts or washouts. However, the higher pressures of the present-day drilling requirements have resulted in higher stresses being imposed on the fluid end which, when combined with the corrosive characteristics of the drilling fluid, have resulted in the demand that more and better maintenance be given to the fluid end parts and pieces if a reasonable operating life is to be obtained. A few of the obvious points is as follows: 1) Make sure all valves on the discharge side of pump are opened before pump is put into operation. Kicking pump in against a closed valve can often be the start of a fatigue crack. An open crack may not necessarily occur at the precise moment, however, a small crack could occur and start the process of “corrosion fatigue failure” 2) Do not engage pump clutch when prime mover is running at a high rate of speed. Which can cause undesirable shock loads against both power end and fluid end. 3) Properly maintain pressure relief valve to assure it is set for the pressure rating on the liner size being used. Refer to the description about the relief valve. 4) Do not operate the pump for an extended period of time if a severe fluid knock is present.

5) Properly prepare fluid end for storage. When pump is to be shut down or not operated for a period of ten days or more, it is recommended that the fluid end parts such as liners, pistons, rods, etc, be removed from the pump and the fluid end be flushed out completely with fresh water, After a thorough flushing, apply grease or a rust preventative to all of the machined surfaces such as valve pot cover threads, valve pot cover gasket surfaces, valve seats, liner bores, etc. The parts removed from the pump including liner, piston rods, etc., should of course be protected correctly. This will not only extend the life of the fluid end through resistance to corrosion, but will also protect the expendable parts still left in the pump and maintain them in good condition for installation in the pump at the next start-up period. The fluid end assembly for these triplex pumps consists of three forged cylinder blocks, complete with valve covers and cylinder heads, a suction manifold, and a discharge manifold.

3.9.2 Suction Manifold The suction manifold (3) bolts to each cylinder block and is sealed through the 0-ring in the connection flange. Thoroughly clean o-ring groove, the 0-ring sealing surface on bottom of the cylinder block, and replace o-ring seal before bolting manifold into position. The flange connection MUST make up metal-to-metal to retain the o-ring seal, therefore any nicks, grooves or washouts on the sealing surface must be repaired before installation. Ref. Welding and Repair Section (3.10) in this manual for repair procedures. Screw all suction manifold bolts (5) in the three cylinder blocks before tightening. Tighten to torque values shown in Chart VI. 3.9.3 Discharge Manifold The discharge manifold bolts to each cylinder block and is sealed through the 0-ring in the connection flange. Thoroughly clean the 0-ring groove, the 0-ring sealing surface on face of the cylinder block before bolting the manifold into position. The flange connection MUST make up metal-to-metal to retain the 0-ring seal, therefore any nicks, grooves, or washouts on this sealing surface must be repaired before installation. Ref. Welding and 38

Repair Section (3.10) in this manual for repair procedures. Start all discharge manifold bolts (8) in the three cylinder blocks before tightening. Tighten to torque values shown in Chart VI. Tight cylinder block to power frame with stud nuts to torque values shown in Chart VI. 3.9.4 Cylinder Head Thread Ring A replaceable cylinder head thread ring (9) is screwed on to the face of the cylinder blocks. The thread ring must make up metal-to-metal with face of cylinder blocks in order for the axis of the threads to be perfectly square with the cylinder block bore. Therefore, make sure all burrs, extrusions, or foreign matter ha
