Hydraulic Pressure Relief Valve (2300PSI) — Tractor Part for International HarvesterMake your hydraulics come alive with this new 2300 PSI IH pressure relief valve from Redrunrite designed for the hydraulic system found on many IH tractors. It will fit 656-1586 and many other IH tractors. The valve is easy to install (it just screws in like a plug), and also makes a great hydraulic troubleshooting tool. We also offer 2500 PSI IH relief valves; however, they can put more strain on your tractor"s hydraulic system.

Pressure relief valves are closely associated with hydraulic pumps, and all fixed-volume pump circuits require a relief valve to limit the system pressure to a specific set level and protect the system from getting damaged due to excess pressure. Over time, the pressure relief valve can get damaged and stop performing. If you own a vintage IH tractor and are facing pressure-related problems and the pressure isn’t building up, the pump or relief valve might have gone bad. Before you change the pump, try to replace the IH relief valve. A new pump will only put out the pressure that the relief valve will allow.

Redrunrite offers competitive pricing on its wide range of products. These valves sell for well over $250.00 from CNH. Place your order for the valve or email us (schmittfarmserv@wwt.net) if you need help choosing the right relief valve for your tractor or diagnosing your hydraulic problems.

Good catch. I forgot the 1300 and 1300F have different ratings on the hydraulics. I wonder why there is a difference between the two (?) I"d be surprised if anything physically is different hydraulically between the 1300 and 1300F version other than the relief valve setting. Can we get some input here from the original designers of these things? :wave: LOL

I also noticed the TX1300 (F) on tractordata.com shows a rear lift weight of 838 lbs. which is what they claim for the 2160 despite it running higher hydraulic pressure. Again my field tests show the 2160 can lift more. Interesting...

The feeling of working outside is one-of-a-kind. You are working by the sweat of your brow, and there is often a timeless sense of purpose and pride in building or reshaping things with your hands. Tractors are great tools that aid us with outdoor endeavors, be they work-related or hobbies and other projects of passion.

Like your car or truck, tractors require basic maintenance, and knowing how to check and properly maintain the appropriate hydraulic fluid levels in your tractor is very important.

Hydrostatics is the physics of dealing with fluids at rest, particularly with the pressure in a fluid or exerted by a fluid, usually in a closed system like a piston.

Hydrodynamics would be dealing with flowing fluids. The hydraulics in your John Deere tractor operate according to the principles of hydrostatics. The enormous pressures generated from having incompressible fluids, like water or oil, have a tremendous capacity to do work in a closed system. The brakes in your John Deere tractor, and your car, all use this principle.

Pressure systems, like hydraulics, are incredibly useful but can be very dangerous when improperly handled or serviced. Your tractor"s hydraulic cylinders that move the bucket or operate the backhoe need to be appropriately maintained. If not, they pose a real safety hazard and can result in expensive repairs.

Using the proper hydraulic equipment is a critical step in performing appropriate checks on your tractor. Before you trust random brands online, you should probably look to established professional brands like Kubota and John Deere - brands trusted by professionals who make their living using these tractors.

Having hydraulics allows your tractor to operate many different tools and have them be powered by the same engine. The diesel engine will power a pump to generate pressure to move the cylinders. With no pressure, you have no ability to work.

Standard tractor attachments like a backhoe or the bucket and blade all operate with hydraulics, and those cylinders you see expanding or contracting are pistons containing differing amounts of hydraulic fluid. If the lines containing the pressurized hydraulic fluid become too low, then you are at risk of a catastrophic failure.

Likewise, too much pressure can also burst the lines. A tractor is a complex machine, exactly like your car or truck. Unlike your car or truck, however, many systems use different hydraulic fluid-filled pressure systems to move tremendous loads.

Modern tractor designs can also feature a hydrostatic transmission, using pressurized hydraulic fluids instead of a traditional belt and gear transmission to transmit power from the engine. Offering many torque advantages, hydrostatic transmissions, like the pistons that power the backhoe or lift the bucket, need the hydraulic fluid to be absolutely clean. Filters need to be replaced or cleaned around every 500 work-hours, if not more frequently

Too little pressure and the cylinders will not move, and you could blow your pump. Too much pressure is equally bad for performance. Your tractor is designed to work best withinin a specific narrow range of pressures, using a special type of hydraulic fluid.

Never operate your tractor if your pressure gauge is not working! A system under high pressure is essentially a bomb waiting to blow. There is a lot of energy in a hydraulic system, and if it is charged too high, a structural defect somewhere can give way to explosive decompression, or an explosion!

However, your hydraulic pressure gauge is not a very smart tool, and despite it registering proper pressure, the cylinders might not be moving. More on this later.

There are many hydraulic fluids that serve different use-cases, but for tractors, you want a specific chemical composition and viscosity, or thickness of the hydraulic fluid. Viscosity is the term for resistance to flow. Compared to water, oil flows more slowly; thus, it is more viscous. Molasses is very viscous. It is essential only to use the proper hydraulic fluid in your tractor, or you risk premature wear and tear that will shorten the useful life of your tractor.

Hydraulic pressure test kits are an essential tool for tractor maintenance as well as an emergency repair. Specially designed for hydraulic fault-finding as well as reporting purposes, they check reliability, safety, and leak tightness of pressure systems like those on your tractor. These hydraulic pressure testers perform operational checks, including the ability to accurately assess:

Although expensive, the return on investment is significant. More so, if you use it as part of a warranty claim, helping you to replace faulty components, and avoid machine downtime and out-of-pocket expenses. Unlike your basic pressure gauge mentioned earlier, these hydraulic pressure testing kits give you an expert level diagnosis of common and uncommon faults with your tractor.

There are many hydraulic pressure adjustment options. Which one is best for you depends heavily on the use-case you have with your tractor. If you are a farmer or work in construction, then the ability to diagnose issues quickly is worth paying more money for a more professional-oriented kit with more components and the ability to diagnose problems across a wide pressure spectrum. For the home-gamer type, this type of kit may be overkill, and a cheaper kit with only a couple components is needed.

Regardless of the type of tester you have, repairing and replacing parts is not the same as diagnosing the issue. Unless you are a certified professional, it is strongly recommended that you do not perform certain repairs yourself. With pressure systems like hydraulics, a part that is improperly installed or is accidentally damaged when replacing another can create a dangerous feedback effect that could result in an accident.

Your tractor is likely a cherished possession. Whether you use it to mow your field, build homes, or farm the land, your tractor is a niche tool that most people will have no active need for. But, as any tractor owner will attest to, if the need for a tractor arises, they can in minutes to hours perform tasks that would require dozens to hundreds of man-hours of labor.

Therefore, it is imperative to make sure that your tractor is adequately maintained. The diesel engine is little different than other internal combustion engine machines you have used, but the hydraulics are a different beast entirely.

Pressurized systems like hydraulic cylinders are tremendously powerful, but if not properly maintained, they are a significant safety hazard. Knowing how to check the various hydraulic fluid levels in your tractor, be it John Deere, Kubota, or something else, is extremely important when it comes to ensuring your tractor is working properly and avoiding costly machine downtime for extensive repairs.

Hydraulics is a term used for the study of liquids and how they function. In engineering, the term hydraulic systems refer to those that work by using pressurized fluid to power an engine. These systems put pressure on a small amount of fluid to generate large amounts of power. The discovery of the use of hydraulics has enabled us to accomplish significant work, such as lifting heavy loads and turning huge shafts with minimum input through a mechanical linkage.

The hydraulic pump draws up oil from the oil reservoir and sends it to the control valve under high pressure. From there, the oil goes to the hydraulic cylinder to operate the piston which in turn raises the lifting arms. The hydraulic pump is operated by suitable gears that are connected with the engine.

These machines use heavy-duty engines as they are subject to a lot of strenuous work. The resulting friction within the engine has to be reduced to maintain performance and increase life. For engines to become more robust and advanced, hydraulic technology must be at the forefront, as these components are the ones that endure the load in driving the crankshafts and must generate a consistently high power delivery.

It wasn’t until the beginning of the industrial revolution when a British mechanic named Joseph Bramah applied the principle of Pascal’s law in the development of the first hydraulic press. In 1795, he patented his hydraulic press, known as the Bramah press. Bramah figured that if a small force on a small area would create a proportionally larger force on a larger area, the only limit to the force that a machine can exert is the area to which the pressure is applied.

Hydraulic systems can be found today in a wide variety of applications, from small assembly processes to integrated steel and paper mill applications. Hydraulics enable the operator to accomplish significant work (lifting heavy loads, turning a shaft, drilling precision holes, etc.) with a minimum investment in mechanical linkage through the application of Pascal’s law, which states:

“Pressure applied to a confined fluid at any point is transmitted undiminished throughout the fluid in all directions and acts upon every part of the confining vessel at right angles to its interior surfaces and equally upon equal areas (Figure 1).”

By applying Pascal’s law and Brahma’s application of it, it is evident that an input force of 100 pounds on 10 square inches will develop a pressure of 10 pounds per square inch throughout the confined vessel. This pressure will support a 1000-pound weight if the area of the weight is 100 square inches.

The principle of Pascal’s law is realized in a hydraulic system by the hydraulic fluidthat is used to transmit the energy from one point to another. Because hydraulic fluid is nearly incompressible, it is able to transmit power instantaneously.

The purpose of the hydraulic reservoir is to hold a volume of fluid, transfer heat from the system, allow solid contaminants to settle and facilitate the release of air and moisture from the fluid.

The hydraulic pump transmits mechanical energy into hydraulic energy. This is done by the movement of fluid which is the transmission medium. There are several types of hydraulic pumps including gear, vane and piston. All of these pumps have different subtypes intended for specific applications such as a bent-axis piston pump or a variable displacement vane pump. All hydraulic pumps work on the same principle, which is to displace fluid volume against a resistant load or pressure.

Hydraulic valves are used in a system to start, stop and direct fluid flow. Hydraulic valves are made up of poppets or spools and can be actuated by means of pneumatic, hydraulic, electrical, manual or mechanical means.

Hydraulic actuators are the end result of Pascal’s law. This is where the hydraulic energy is converted back to mechanical energy. This can be done through use of a hydraulic cylinder which converts hydraulic energy into linear motion and work, or a hydraulic motor which converts hydraulic energy into rotary motion and work. As with hydraulic pumps, hydraulic cylinders and hydraulic motors have several different subtypes, each intended for specific design applications.

There are several components in a hydraulic system that are considered vital components due to cost of repair or criticality of mission, including pumps and valves. Several different configurations for pumps must be treated individually from a lubrication perspective. However, regardless of pump configuration, the selected lubricant should inhibit corrosion, meet viscosity requirements, exhibit thermal stability, and be easily identifiable (in case of a leak).

There are many variations of vane pumps available between manufacturers. They all work on similar design principles. A slotted rotor is coupled to the drive shaft and turns inside of a cam ring that is offset or eccentric to the drive shaft. Vanes are inserted into the rotor slots and follow the inner surface of the cam ring as the rotor turns.

The vanes and the inner surface of the cam rings are always in contact and are subject to high amounts of wear. As the two surfaces wear, the vanes come further out of their slot. Vane pumps deliver a steady flow at a high cost. Vane pumps operate at a normal viscosity range between 14 and 160 cSt at operating temperature. Vane pumps may not be suitable in critical high-pressure hydraulic systems where contamination and fluid quality are difficult to control. The performance of the fluid’s antiwear additive is generally very important with vane pumps.

As with all hydraulic pumps, piston pumps are available in fixed and variable displacement designs. Piston pumps are generally the most versatile and rugged pump type and offer a range of options for any type of system. Piston pumps can operate at pressures beyond 6000 psi, are highly efficient and produce comparatively little noise. Many designs of piston pumps also tend to resist wear better than other pump types. Piston pumps operate at a normal fluid viscosity range of 10 to 160 cSt.

There are two common types of gear pumps, internal and external. Each type has a variety of subtypes, but all of them develop flow by carrying fluid between the teeth of a meshing gear set. While generally less efficient than vane and piston pumps, gear pumps are often more tolerant of fluid contamination.

Internal gear pumps produce pressures up to 3000 to 3500 psi. These types of pumps offer a wide viscosity range up to 2200 cSt, depending on flow rate and are generally quiet. Internal gear pumps also have a high efficiency even at low fluid viscosity.

External gear pumps are common and can handle pressures up to 3000 to 3500 psi. These gear pumps offer an inexpensive, mid-pressure, mid-volume, fixed isplacement delivery to a system. Viscosity ranges for these types of pumps are limited to less than 300 cSt.

Today’s hydraulic fluids serve multiple purposes. The major function of a hydraulic fluid is to provide energy transmission through the system which enables work and motion to be accomplished. Hydraulic fluids are also responsible for lubrication, heat transfer and contamination control. When selecting a lubricant, consider the viscosity, seal compatibility, basestock and the additive package. Three common varieties of hydraulic fluids found on the market today are petroleum-based, water-based and synthetics.

Petroleum-based or mineral-based fluids are the most widely used fluids today. These fluids offer a low-cost, high quality, readily available selection. The properties of a mineral-based fluid depend on the additives used, the quality of the original crude oil and the refining process. Additives in a mineral-based fluid offer a range of specific performance characteristic. Common hydraulic fluid additives include rust and oxidation inhibitors (R&O), anticorrosion agents, demulsifiers, antiwear (AW) and extreme pressure (EP) agents, VI improvers and defoamants. Additionally, some of these lubricants contain colorful dyes, allowing you to easily identify leaks. Because hydraulic leaks are so costly (and common), this minor characteristic plays a huge role in extending the life of your equipment and saving your plant money and resources.

Elevated temperatures cause the water in the fluids to evaporate, which causes the viscosity to rise. Occasionally, distilled water will have to be added to the system to correct the balance of the fluid. Whenever these fluids are used, several system components must be checked for compatibility, including pumps, filters, plumbing, fittings and seal materials.

Synthetic fluids are man-made lubricants and many offer excellent lubrication characteristics in high-pressure and high- temperature systems. Some of the advantages of synthetic fluids may include fire-resistance (phosphate esters), lower friction, natural detergency (organic esters and ester-enhanced synthesized hydrocarbon fluids) and thermal stability.

When choosing a hydraulic fluid, consider the following characteristics: viscosity, viscosity index, oxidation stability and wear resistance. These characteristics will determine how your fluid operates within your system. Fluid property testing is done in accordance with either American Society of Testing and Materials (ASTM) or other recognized standards organizations.

Viscosity (ASTM D445-97) is the measure of a fluid’s resistance to flow and shear. A fluid of higher viscosity will flow with higher resistance compared to a fluid with a low viscosity. Excessively high viscosity can contribute to high fluid temperature and greater energy consumption. Viscosity that is too high or too low can damage a system, and consequently, is the key factor when considering a hydraulic fluid.

Viscosity Index (ASTM D2270) is how the viscosity of a fluid changes with a change in temperature. A high VI fluid will maintain its viscosity over a broader temperature range than a low VI fluid of the same weight. High VI fluids are used where temperature extremes are expected. This is particularly important for hydraulic systems that operate outdoors.

Aside from these fundamental characteristics, another property to consider is visibiilty. If there is ever a hydraulic leak, you want to catch it early on so you don"t damage your equipment. Opting for adyed lubricant can help you spot leaks quickly, effectively saving your plant from machine failure.

When selecting lubricants, ensure that the lubricant performs efficiently at the operating parameters of the system pump or motor. It is useful to have a defined procedure to follow through the process. Consider a simple system with a fixed-displacement gear pump that drives a cylinder (Figure 2).

Collect all relevant data for the pump. This includes collecting all the design limitations and optimum operating characteristics from the manufacturer. What you are looking for is the optimum operating viscosity range for the pump in question. Minimum viscosity is 13 cSt, maximum viscosity is 54 cSt, and optimum viscosity is 23 cSt.

Check the actual operating temperature conditions of the pump during normal operation. This step is extremely important because it gives a reference point for comparing different fluids during operation. Pump normally operates at 92ºC.

Using the manufacturer’s data for the pump’s optimum operating viscosity, find the value on the vertical viscosity axis of the chart. Draw a horizontal line across the page until it hits the yellow viscosity vs. temperature line of the lubricant. Now draw a vertical line (green line, Figure 5) to the bottom of the chart from the yellow viscosity vs. temperature line where it is intersected by the horizontal optimum viscosity line. Where this line crosses, the temperature axis is the optimum operating temperature of the pump for this specific lubricant (69ºC).

Repeat Step 8 for maximum continuous and minimum continuous viscosities of the pump (brown lines, Figure 5). The area between the minimum and maximum temperatures is the minimum and maximum allowable operating temperature of the pump for the selected lubricant product.

Find the normal operating temperature of the pump on the chart using the heat gun scan done in Step 2. If the value is within the minimum and maximum temperatures as outlined on the chart, the fluid is suitable for use in the system. If it is not, you must change the fluid to a higher or lower viscosity grade accordingly. As shown in the chart, the normal operating conditions of the pump are out of the suitable range (brown area, Figure 5) for our particular lubricant and will have to be changed.

The purpose of hydraulic fluid consolidation is to reduce complexity and inventory. Caution must be observed to consider all of the critical fluid characteristics required for each system. Therefore, fluid consolidation needs to start at the system level. Consider the following when consolidating fluids:

Hydraulic systems are complicated fluid-based systems for transferring energy and converting that energy into useful work. Successful hydraulic operations require the careful selection of hydraulic fluids that meet the system demands. Viscosity selection is central to a correct fluid selection.
