Are you looking for an excavator hydraulic pump replacement? Or are you simply looking to be more enlightened on your excavator’s hydraulic systems? Then this is the guide for you!

An excavator hydraulic pump is one of the crucial elements in your excavator. It is so essential that an excavator cannot work without it. In this guide, you are going to learn:

Excavator hydraulic pumps enable your excavator to move around and work effectively and efficiently. Whenever you hear the term “hydraulic,” you can be sure that it means liquid used to carry out a specific task.

You’ll find out that different excavator makes and models have different designs. It would be best to find out the location of your excavator hydraulic pump by reading the excavator’s operational manual.

There are different types and models of hydraulic pumps in the market today. You’ll need to find out which one your excavator uses for the best power output.

Hydraulic excavators have three hydraulic pumps. Among the three pumps, there are two main ones that pump oil at extremely high pressure. These two are called variable displacement pumps.

Your excavator has three hydraulic pumps. Among these three pumps, there are two main pumps that supply oil at extremely high pressure. The third one does not provide high pressure compared to the former two.

The two main hydraulic pumps fall under the category of variable displacement pumps. The third pump is simply a gear pump, as discussed earlier in this guide.

However, variable displacement pumps have a quite complex working principle. Consider watching this short 3D video that illustrates clearly how your excavator hydraulic pump works.

Surprisingly, not all of them are good for your excavator. You’ll need to contact a professional company to help you figure out which hydraulic pump will be ideal for your excavator.

Your excavator hydraulic pump works so hard. Over time, its internal components wear out. Whenever there is any foreign matter, like debris, it may cause your excavator hydraulic pump to overheat.

Damaged internal components will require repairs or replacement, depending on the magnitude of damage. Further, when your excavator hydraulic oil gets old, it becomes useless. It cannot lubricate and protect the surfaces of the internal components.

Lack of proper maintenance will certainly make your excavator hydraulic pump overheat. There is no shortcut – you’ll have to service your excavator hydraulic systems. It’s important to use the correct type and, more importantly, the correct amount of oil.

It’s imperative to check the oil level of your excavator hydraulic pump regularly. It helps you ensure that there are no leakages in your system. Checking oil also helps you know the quality of oil in the hydraulic pump.

It’s also important to check the condition of the hydraulic pump’s heat exchanger. A faulty excavator hydraulic pump heat exchanger will lead to overheating problems.

There are times that you’ll need to tweak your hydraulic pump so that it can perform better in a certain task. However, you have to understand that the hydraulic pump is a system that has to work in harmony.

Any changes that you introduce alters the balance of the hydraulic pump, and this may make it overheat. A common adjustment that many professionals make to their hydraulic pumps is by adjusting the pump compensator.

There are many excavator hydraulic pump mods and upgrades in the market today. These mods and upgrades will promise you more power and better efficiency. However, not all of them work well with your hydraulic pump.

An upgrade might promise you a higher flow pump which offers increased capabilities to your hydraulic pump. Have you considered checking if your hydraulic pump’s internal structure can handle that increase in flow?

If the internal structure has smaller hoses and pipes than the flow that you’ve selected, there will be a lot of pressure buildup. This pressure buildup will cause your excavator hydraulic pump to overheat.

Whenever any excavator component gets damaged, there are some anomalies that the excavator must show you. You’ll know when your hydraulic pump is damaged when it starts behaving abnormally.

There are so many factors that cause your excavator hydraulic pump to fail. It can fail prematurely or over time due to normal wearing out of internal components. Check out the frequently observed reasons why your excavator hydraulic pump fails:

Your excavator hydraulic pump is supposed to be completely sealed off to prevent the entrance of contaminants. The most common contaminants are water and air. Water contamination accounts for 90% of the total excavator hydraulic pump failures.

Cavitation – when your excavator hydraulic pump has cavitation, it’ll produce a whining sound. It would be best to handle this issue whenever you hear a whining sound coming from your excavator hydraulic pump.

Aeration – This happens when your excavator hydraulic pump allows external air to enter inside it. Aeration can happen when your excavator hydraulic pump has loose components.

You’ll know that your excavator hydraulic pump has aeration when it starts producing knocking sounds whenever it runs. You’ll need to handle this issue with urgency as it can damage the whole excavator hydraulic pump.

Your excavator hydraulic pump may have temperature issues – running too cold or too hot. These temperature problems will undoubtedly cause further problems. Check out the symptoms your excavator hydraulic pump will show you when it faces temperature issues:

You’ve probably been through that science class where you discussed oil viscosity. Low temperatures make oil thicken by increasing its viscosity. When your oil is highly viscous, it may fail to reach your excavator hydraulic pump.

It’s important to let your excavator heat oil up (preferably past 70 degrees) before you start using it. If you do not do this, you may end up damaging your excavator hydraulic pump through cavitation.

Whenever your hydraulic pump works in an environment that is exorbitantly hot, your hydraulic fluid may become too thin. The thin hydraulic fluid prevents lubrication. It further causes leakages, meaning that your excavator hydraulic pump will be running low on hydraulic fluid.

Oxidation occurs because of extreme heat. This may cause your hydraulic fluid to thicken after oxidizing. This thickening is what causes buildup inside your excavator hydraulic pump. It will definitely make your hydraulic pump overheat whenever it works.

It’s important to ensure that your hydraulic fluid’s quality and quantity (level) is okay. The level of hydraulic fluids can cause severe damages to your hydraulic pump.

For example, low levels of hydraulic fluids bring about air contamination (cavitation). It further causes your hydraulic pump to overheat. When your excavator hydraulic fluid leaks, you’ll experience the same problems.

The quality of your excavator hydraulic pump is also important, as different hydraulic fluids are compatible according to different situations. The quality of hydraulic fluids is also important as it helps you lengthen the service life of your excavator hydraulic pump.

As the saying goes, man is to error. Some failures occur due to this reason. Check out the most frequent areas where human faults have brought excavator hydraulic pump failures:

Wrong Maintenance –  you may fail to maintain your excavator hydraulic pump as it should properly. This fault will certainly make your excavator hydraulic pump fail.

Using wrong or incompatible spare parts – If a spare part is incompatible, consider contacting a professional company that will supply you with the right part. Using the incorrect part will damage your excavator hydraulic pump.

Your mechanic may also install hydraulic hoses wrongly by twisting them. Once you twist an excavator hydraulic pump hose and set it at a wrong angle, you reduce that hose’s service life by at least 80%.

Worn-out seals or valves: Whenever you have worn out seals or valves, your excavator hydraulic pump will allow hydraulic fluid to leak. You’ll need to replace the faulty seals to solve this problem.

Poor quality of hydraulic fluid – whenever your hydraulic pump works, it heats up the hydraulic fluid. When your oil gets heated up, and it is of poor quality, it’ll become too thin, and it will start leaking. Consider using the right amount and quality of hydraulic fluids.

Failing seals because of underlying issues: Your excavator hydraulic pump may leak oil because of failing seals that are caused by an underlying issue. The most frequent cause for failing seals is a misaligned rod. Correcting a misaligned rod is not an entirely complex procedure. A skilled mechanic can do that.

Identifying failures before they are full-blown is necessary. It’s important to know how to troubleshoot your excavator hydraulic pump. Check out how it is done:

Check your hydraulic fluids – It’s important to check your hydraulic fluids to maintain your excavator hydraulic pump’s health. You’ll need to check its color, viscosity, and level inside the hydraulic pump. Ensure that it is not contaminated. If you are in doubt of anything, you’ll need to replace the hydraulic fluid.

Rebuilding your excavator hydraulic pump is a complex and delicate process. It would be best if you’d let a skilled and certified professional help you out instead of doing it all on your own.

Your excavator hydraulic pump is an expensive device. Further, it deals with pressure. In case you fail to install the components properly, it will not work. You’ll have already voided your warranty cover.

Different types of excavators produce different amounts of power. This variation in power means that the power produced by their hydraulic pumps is not the same.

Your excavator has three hydraulic pumps – two main ones and a third one called the gear pump. Now, your excavator’s two main pumps will supply pressurized oil at 5,000 pounds per square inch (psi).

It’s important to check the health of your excavator hydraulic pump regularly. Regular checks help you know if your excavator hydraulic pump is still healthy.

Replacing your hydraulic excavator drive is not an easy process. All excavator repairs and maintenance should be done by licensed professionals only. It’s important for you to refer to your excavator’s manual to understand your excavator hydraulic pump.

Remember, the reason why you are replacing your excavator hydraulic pump is that your initial pump got damaged either by heat, contamination or by cavitation/aeration. You’ll need to check the hydraulic tank cap seals.

The tank cap helps your excavator hydraulic pump to maintain its tank pressure, and it also has to breathe. Damaged seals can cause aeration and cavitation to the hydraulic pump. You’ll also need to replace your suction screen with a new one.

Further, it is important for you to drain your excavator tank when replacing the suction screen. It helps you prevent catastrophic failure. You’ll also replace your hydraulic oil filter to prevent contamination of new oil when you install the new hydraulic pump.

Before installing your new excavator hydraulic pump, you’ll need to inspect and confirm that all its electrical connectors are intact – for both the excavator and the hydraulic pump. Poor wiring (incorrect setup) causes an electronic system’s failure on your device.

Now, you’ll need to use a machine that will help you lift your hydraulic pump from the ground to its allotted spot on the excavator. Excavator hydraulic pumps are heavy (approximately 180kgs).

It’ll help you have a smooth installation. Then, align your excavator hydraulic pump to where it should be and slide it in. Return all the hydraulic pipes as they were and tighten them to prevent contamination – mainly aeration and entry of water.

To ensure that you have the best results, it would be best to install a cleanup filter. After installing the cleanup filter, run the excavator’s engine for up to four hours (minimum two hours) at 60% RPM.

Warming your hydraulic system helps you prevent the entry of debris in your hydraulic system. Cold hydraulic fluid can allow debris to pass through to your hydraulic system.

Install the suction screen and return everything to how they were before you began the excavator hydraulic pump replacement process. Since there is unwanted air inside the pump, you can get rid of it by bleeding it (air) from your excavator’s highest cap.

For hydraulic pumps that do not have caps, you’ll still need to get rid of the air present in your excavator hydraulic pump. You can do so by cracking the suction elbow at the pump up to when there will be hydraulic fluid leakage.

You’ll need to remember that different regions of the world have different working temperatures. It would be best if you’d consult a skilled professional on the type of oil to use for your excavator hydraulic.

As you warm your excavator hydraulic pump, keep on checking the level of hydraulic oil. The reason why this constant checking is important is that insufficient oil levels bring about the formation of moisture (venting) which eventually leads to rusting.

Different makes and models of excavator hydraulic pumps have different excavator hydraulic pump prices. Also, service rates differ from one region to another.

It would be best if you’d contact a reliable company to supply you with your excavator hydraulic pump that meets your budget. You’ll then need to look for a skilled and certified mechanic to install the excavator hydraulic pump.

Our excavator hydraulic pumps are covered with a 90-day warranty period. Failure to reach out to a skilled and certified mechanic voids your warranty.

Your excavator’s hydraulic pump has a coupling device that should be installed between the device itself and the excavator engine. The coupling device enables your excavator to have an additional external force.

It enables the torque generated by the engine on the pump to be equal to the torque the turbine receives, which is then transmitted to your excavator’s driveshaft. There are two primary benefits associated with excavator hydraulic pump coupling:

It would be best if you’d refer to both your service and operation manual on how you can adjust your excavator hydraulic pump. Remember that improper adjustment of your excavator hydraulic pump makes your device overheat.
