Powering a hydraulic pump to a power take-off (PTO) is a common practice. Within mobile hydraulic applications, there are three types of hydraulic pump construction typically found including gear, piston and vane.

Gear pumps are the most common design used in truck mounted hydraulic systems, as the gear pump is relatively inexpensive with its fewer moving parts, ability to be easily serviced and greater tolerance to contamination than other designs.

A hydraulic pump for mobile applications, like the gear, piston or vane pump, can be either direct mounted to the PTO or remote mounted – using a driveline. While each type is a viable option for mounting a hydraulic pump, it is important to understand each type of mount to ensure an effective connection is made between the PTO and pump.

In a direct mount the hydraulic pump is mounted directly to the output flange of the PTO. Direct mounting is the most common type of installation in the mobile equipment industry. When direct mounting a pump it is necessary to:

Select the correct pump rotation to match the PTO output rotation or select what is known as a bi-rotational pump, which tends to have equally sized ports since either can be the inlet or outlet.

For mobile, truck mounted hydraulic systems the most common pump mount is the SAE B, which is a 7/8” diameter shaft with 13 splines – one of the standard pump mounting configurations established by the Society of Automotive Engineers (SAE).

Disadvantages to direct mounting a pump• Concealed maintenance points, which include periodic removal and replacement of grease at the pump to PTO connection

Sometimes it is not possible to direct mount a hydraulic pump, requiring the pump to be remote mounted some distance away from the PTO and then powered from the power take-off by means of a driveline assembly. The correct type and series of driveline must be selected. Solid shafting is not recommended as it cannot be balanced and can vibrate, damaging the PTO and pump shaft seals – causing leaks. The better choice is a balanced, tubular assembly designed to meet the speed, torque and horsepower requirements of the application.

When using a driveline, it is important that it be in phase and incorporates a slip yoke at one end. Round, keyed PTO output shafts are susceptible to failure by high cyclic loading. An out of phase shaft will vibrate and damage the PTO and pump shaft seals while a functioning slip yoke will allow the shaft to adjust for flexing of the truck chassis. As part of a regularly scheduled, preventative maintenance plan, the slip yoke and bearings of the driveline must be lubricated.

Powering a pump to a PTO is a common practice, but selecting whether to direct or remote mount the pump takes understanding and careful consideration. Regardless of the type of mount you select, remember that this understanding of each mount – along with its advantages and its drawbacks – will be the key to creating an effective, lasting connection between the PTO and pump.

Proper power take-off (PTO) selection requires specific knowledge of the vehicle’s transmission and the driven component. With this information, selection is a relatively simple process. So, what do you need to know?

Which aperature will the PTO be mounted? This is generally dependent on the available space around the PTO aperature (i.e. the PTO envelope space). Be sure to note the presence of exhaust pipes, spring hangers, air tanks, etc.

The speed requirement of the driven component and or the desired PTO percentage. If the PTO is being used to power a hydraulic pump it is common to specify a PTO percentage of 90 to 120 percent.

In addition to meeting the speed and rotational requirements of the driven component, the PTO must also meet the torque and horsepower requirements of the application. This information can usually be found in the owner’s manual of the equipment or by contacting the manufacturer or distributor. There are also mathematical formulae that can be used to calculate these requirements.

The most common application for a PTO is to provide power to a hydraulic pump. If the flow and pressure requirements of the hydraulic system are known, the horsepower requirement can be calculated by the formula:

In mechanical applications where the PTO is supplying power directly to a driven component, the RPM and horsepower requirements must be obtained from an owner’s manual, specification sheet, or by contacting the manufacturer or distributor of the component.

All PTOs have torque and horsepower limitations. With the Muncie Power Products Quick Reference Catalog for instance, these can be found on the application pages. It is important to remember two things about the published torque and horsepower ratings in Muncie Power’s catalog:

Horsepower is directly proportional to PTO output shaft speed and the published ratings are at 1000 RPM. A PTO rated at 40 HP at 1000 RPM; therefore, can deliver 80 HP at a shaft speed of 2000 RPM, but only 20 HP at a shaft speed of 500 RPM.

Mechanical PTOs are those which are engaged when gears slide into mesh with each other. Since a PTO is essentially a non-synchronized gearbox, it is important that the operator make certain that the transmission gears stop turning before engaging the PTO. Engaging a mechanical PTO with the transmission gears turning will result in PTO and or transmission damage.

Mechanical PTOs are commonly engaged by means of a lever, cable, or air pressure, and are typically found on manual transmissions. Muncie Power’s TG Series is the most popular mechanical shift PTO. Other Muncie Power model series of this type are the SH Series and 82 Series.

On the other hand, the most common PTO found on an automatic transmission is a clutch shift PTO. Rather than engaging by means of a sliding gear, the clutch shift PTO utilizes clutch disks and friction plates to engage. When hydraulic or air pressure is applied to an internal piston the clutch disks and friction plates are forced together, engaging the PTO. Since there is no possibility of gear clash, this type of PTO can even be engaged with the vehicle in motion (as long as the truck engine speed remains under 1000 RPM). Muncie Power’s clutch shift PTO series include the A20 Series, CS10/11 Series, and CS41 Series models.

Check that the electric motor is running. Although this is a simple concept, before you begin replacing parts, it’s critical that you make sure the electric motor is running. This can often be one of the easiest aspects to overlook, but it is necessary to confirm before moving forward.

Check that the pump shaft is rotating. Even though coupling guards and C-face mounts can make this difficult to confirm, it is important to establish if your pump shaft is rotating. If it isn’t, this could be an indication of a more severe issue, and this should be investigated immediately.

Check the oil level. This one tends to be the more obvious check, as it is often one of the only factors inspected before the pump is changed. The oil level should be three inches above the pump suction. Otherwise, a vortex can form in the reservoir, allowing air into the pump.

If the oil level is low, determine where the leak is in the system. Although this can be a difficult process, it is necessary to ensure your machines are performing properly. Leaks can be difficult to find.

What does the pump sound like when it is operating normally? Vane pumps generally are quieter than piston and gear pumps. If the pump has a high-pitched whining sound, it most likely is cavitating. If it has a knocking sound, like marbles rattling around, then aeration is the likely cause.

Cavitation is the formation and collapse of air cavities in the liquid. When the pump cannot get the total volume of oil it needs, cavitation occurs. Hydraulic oil contains approximately nine percent dissolved air. When the pump does not receive adequate oil volume at its suction port, high vacuum pressure occurs.

This dissolved air is pulled out of the oil on the suction side and then collapses or implodes on the pressure side. The implosions produce a very steady, high-pitched sound. As the air bubbles collapse, the inside of the pump is damaged.

While cavitation is a devastating development, with proper preventative maintenance practices and a quality monitoring system, early detection and deterrence remain attainable goals. UE System’s UltraTrak 850S CD pump cavitation sensor is a Smart Analog Sensor designed and optimized to detect cavitation on pumps earlier by measuring the ultrasound produced as cavitation starts to develop early-onset bubbles in the pump. By continuously monitoring the impact caused by cavitation, the system provides a simple, single value to trend and alert when cavitation is occurring.

The oil viscosity is too high. Low oil temperature increases the oil viscosity, making it harder for the oil to reach the pump. Most hydraulic systems should not be started with the oil any colder than 40°F and should not be put under load until the oil is at least 70°F.

Many reservoirs do not have heaters, particularly in the South. Even when heaters are available, they are often disconnected. While the damage may not be immediate, if a pump is continually started up when the oil is too cold, the pump will fail prematurely.

The suction filter or strainer is contaminated. A strainer is typically 74 or 149 microns in size and is used to keep “large” particles out of the pump. The strainer may be located inside or outside the reservoir. Strainers located inside the reservoir are out of sight and out of mind. Many times, maintenance personnel are not even aware that there is a strainer in the reservoir.

The suction strainer should be removed from the line or reservoir and cleaned a minimum of once a year. Years ago, a plant sought out help to troubleshoot a system that had already had five pumps changed within a single week. Upon closer inspection, it was discovered that the breather cap was missing, allowing dirty air to flow directly into the reservoir.

A check of the hydraulic schematic showed a strainer in the suction line inside the tank. When the strainer was removed, a shop rag was found wrapped around the screen mesh. Apparently, someone had used the rag to plug the breather cap opening, and it had then fallen into the tank. Contamination can come from a variety of different sources, so it pays to be vigilant and responsible with our practices and reliability measures.

The electric motor is driving the hydraulic pump at a speed that is higher than the pump’s rating. All pumps have a recommended maximum drive speed. If the speed is too high, a higher volume of oil will be needed at the suction port.

Due to the size of the suction port, adequate oil cannot fill the suction cavity in the pump, resulting in cavitation. Although this rarely happens, some pumps are rated at a maximum drive speed of 1,200 revolutions per minute (RPM), while others have a maximum speed of 3,600 RPM. The drive speed should be checked any time a pump is replaced with a different brand or model.

Every one of these devastating causes of cavitation threatens to cause major, irreversible damage to your equipment. Therefore, it’s not only critical to have proper, proactive practices in place, but also a monitoring system that can continuously protect your valuable assets, such as UE System’s UltraTrak 850S CD pump cavitation senor. These sensors regularly monitor the health of your pumps and alert you immediately if cavitation symptoms are present, allowing you to take corrective action before it’s too late.

Aeration is sometimes known as pseudo cavitation because air is entering the pump suction cavity. However, the causes of aeration are entirely different than that of cavitation. While cavitation pulls air out of the oil, aeration is the result of outside air entering the pump’s suction line.

Several factors can cause aeration, including an air leak in the suction line. This could be in the form of a loose connection, a cracked line, or an improper fitting seal. One method of finding the leak is to squirt oil around the suction line fittings. The fluid will be momentarily drawn into the suction line, and the knocking sound inside the pump will stop for a short period of time once the airflow path is found.

A bad shaft seal can also cause aeration if the system is supplied by one or more fixed displacement pumps. Oil that bypasses inside a fixed displacement pump is ported back to the suction port. If the shaft seal is worn or damaged, air can flow through the seal and into the pump’s suction cavity.

As mentioned previously, if the oil level is too low, oil can enter the suction line and flow into the pump. Therefore, always check the oil level with all cylinders in the retracted position.

If a new pump is installed and pressure will not build, the shaft may be rotating in the wrong direction. Some gear pumps can be rotated in either direction, but most have an arrow on the housing indicating the direction of rotation, as depicted in Figure 2.

Pump rotation should always be viewed from the shaft end. If the pump is rotated in the wrong direction, adequate fluid will not fill the suction port due to the pump’s internal design.

A fixed displacement pump delivers a constant volume of oil for a given shaft speed. A relief valve must be included downstream of the pump to limit the maximum pressure in the system.

After the visual and sound checks are made, the next step is to determine whether you have a volume or pressure problem. If the pressure will not build to the desired level, isolate the pump and relief valve from the system. This can be done by closing a valve, plugging the line downstream, or blocking the relief valve. If the pressure builds when this is done, there is a component downstream of the isolation point that is bypassing. If the pressure does not build up, the pump or relief valve is bad.

If the system is operating at a slower speed, a volume problem exists. Pumps wear over time, which results in less oil being delivered. While a flow meter can be installed in the pump’s outlet line, this is not always practical, as the proper fittings and adapters may not be available. To determine if the pump is badly worn and bypassing, first check the current to the electric motor. If possible, this test should be made when the pump is new to establish a reference. Electric motor horsepower is relative to the hydraulic horsepower required by the system.

For example, if a 50-GPM pump is used and the maximum pressure is 1,500 psi, a 50-hp motor will be required. If the pump is delivering less oil than when it was new, the current to drive the pump will drop. A 230-volt, 50-hp motor has an average full load rating of 130 amps. If the amperage is considerably lower, the pump is most likely bypassing and should be changed.

Figure 4.To isolate a fixed displacement pump and relief valve from the system, close a valve or plug the line downstream (left). If pressure builds, a component downstream of the isolation point is bypassing (right).

The most common type of variable displacement pump is the pressure-compensating design. The compensator setting limits the maximum pressure at the pump’s outlet port. The pump should be isolated as described for the fixed displacement pump.

If pressure does not build up, the relief valve or pump compensator may be bad. Prior to checking either component, perform the necessary lockout procedures and verify that the pressure at the outlet port is zero psi. The relief valve and compensator can then be taken apart and checked for contamination, wear, and broken springs.

Install a flow meter in the case drain line and check the flow rate. Most variable displacement pumps bypass one to three percent of the maximum pump volume through the case drain line. If the flow rate reaches 10 percent, the pump should be changed. Permanently installing a flow meter in the case drain line is an excellent reliability and troubleshooting tool.

Ensure the compensator is 200 psi above the maximum load pressure. If set too low, the compensator spool will shift and start reducing the pump volume when the system is calling for maximum volume.

Performing these recommended tests should help you make good decisions about the condition of your pumps or the cause of pump failures. If you change a pump, have a reason for changing it. Don’t just do it because you have a spare one in stock.

Conduct a reliability assessment on each of your hydraulic systems so when an issue occurs, you will have current pressure and temperature readings to consult.

The Bezares 4200 Series Mechanical PTO is a dual output, eight-bolt, heavy-duty PTO with two independently air-operated outputs and a variety of ratio and output combinations. It is extremely versatile for many applications where two PTOs would be required.

Power Takeoff (PTO) units are complicated devices that perform many tasks on work trucks, but generally are used to provide power to hydraulic systems. There are more than a million PTO configurations depending on several factors, including the vehicle, the transmission, the application (work to be done), the required torque and horsepower needs to perform the work in a safe and efficient manner.

To further complicate matters, PTOs operate hydraulic systems which include a range of components for commercial vehicles, including pumps, fittings, tanks, valves and other related mobile power hydraulic components.

These challenges make selecting the right PTO a daunting task, without factoring in changing technology, new products, and changing application demands for vehicles. However, specialty companies who focus on the mobile power hydraulic market, like Eaton and others, can help ensure customers have the right mobile power system, including the PTO, for the job to be done.

One of the first decisions to make when spec’ing a PTO is how fast you want to run the engine when performing work. For example, if it’s a blower system, you must determine the torque specifications required to operate efficiently. Then you must match the vehicle’s transmission to the PTO and determine the best mounting location.

Other factors that determine a proper PTO include whether the vehicle has a manual, automatic or automated transmission and, depending on its age, what type of electronic control unit (ECU) is installed, as the PTO may have to be programed for proper operation.

Further complicating the product identification process is that each PTO component and manufacturer comes with a different part number, different ratios, and specifications making the ordering process confusing.

It’s important to remember there are experts that can help. For example, Eaton has streamlined and simplified the process with its “End Dump wet kit” packages for the Bezares brand of Mobile Power products including Power Takeoff (PTO) units.

The currently established kits fit popular Eaton Fuller and Eaton Cummins transmissions. The wet kits simplify the ordering and installation process by including all the components needed into a single part number. Offering all the needed components in one kit saves time to spec and receive compared to ordering individual parts and allows for a seamless installation.

Wet kits are installed on medium- and heavy-duty trucks that have accessories like booms and cranes that need hydraulic pumps to operate. The wet kits" hydraulic system is activated by the PTO mounted to the truck"s transmission.

Once installed properly, maintaining a mobile power system and PTO becomes a top priority. Failure to do so could lead to poor performance, unplanned down time, costly repairs, and more.

One rule of thumb for PTO maintenance is to have it inspected during normal or routine transmission maintenance, and make repairs, if needed, at that time. Since the PTO and transmission work together, inspecting and maintaining together can save time and money while ensure the efficient operation of your mobile power system.

Normal maintenance should include inspecting the connections between the pump and PTO for leaks, inspecting seals, cleaning and lubricating the shafts between the pump and PTO, and removing of any foreign objects, such as metal shavings, dirt and road grime. Looking for and repairing these commonly missed maintenance items will ensure the smooth operation of the system. Finally, receiving feedback from equipment operators is essential, as they are most likely to notice any unusual operation or noises and can help direct needed attention within the system.

Spec’ing the correct PTO for the vehicle and application, and properly maintaining it, will optimize performance and extend the lifecycle of the unit to provide years of reliable service.

It is recommended to begin analyzing a PTO application using pre-determined necessary technical information about the work output and installation requirements. Go through the following steps to specify a PTO.

Determine the transmission information being used (i.e. automatic or manual, make, model, side of installation). Parker Chelsea has an application guide that will help organize the necessary information needed. There are identification tags on the transmission itself that provide the make and model of the transmission which is required for the application worksheet.

Establish the approximate engine speed desired during operation or PTO ratio (if known). PTO speed is stated as a percentage of engine speed. An example being the required pump speed of 1000 RPM and having an engine operating speed of 1500 RPM. The percentage of PTO to engine speed would be calculated to approximately two-thirds, or approximately 67 percent (e.g. 1000/1500 = 66.67, or 67%).

Define the direction of the Driven Equipment Shaft Rotation with there being two choices, engine and opposite-engine. The PTO requirements will be determined by the driven equipment. It is important to note the PTO output shaft rotation listed on the application page is in relation to the vehicle crankshaft rotation as viewed from the rear of the vehicle.(See Figure 1).

Define the duty cycle as intermittent or continuous. Intermittent duty cycles are defined as PTO operations that last for less than five minutes in any fifteen-minute period. Conversely, continuous duty cycles are defined as PTO operations for more than five minutes out of every 15. If an intermittent PTO is used for continuous operation, the required torque must be divided by .70 to get the torque requirement for the driven equipment. The PTO will need to de-rated if it was not designed for continuous duty.

Determine the type and size of the PTO output required (i.e. driveshaft – the size of output required, direct mount pump – mounting flange and shaft type/size).

While not all information is always available, here is an informal guideline that can get you started with the right information to help you select the right PTO for your application.

It is important to remember when the appropriate PTO has been selected through the concluded gathered information, review the application guide, and make sure that all the necessary information has been included. When searching for a PTO in a catalog, please remember to read the footnotes as there may be additional information to consider for specifying a PTO. This can include transmissions not being able to withstand torque capacity of the PTO and the application or some other unique feature of the unit may be mentioned through the footnotes.
