Like any other forklift, Clark forklifts rely on hydraulic systems to carry out their material handling jobs quickly and efficiently. Among all of Clark forklift's hydraulic system parts, the hydraulic pump is the most important. That's why it's crucial to know how to detect their possible faults when they start to appear, either to correct them or to replace the pump itself. With this in mind, Lift Parts Warehouse wants to share a little more about this essential device and what considerations you have to consider when purchasing its replacement.
What is the Function of a Clark Forklift Hydraulic Pump?
Clark lift trucks use hydraulic pumps that are essentially mechanical actuators that transform mechanical power into hydraulic energy. All hydraulic pumps for Clark forklifts perform two different processes to operate successfully. First, a mechanical action known as a vacuum is created at the pump inlet. This action allows natural pressure to propel fluid from the device's reservoir to the line to the pump. Second, this action forces this fluid into the pump outlet and moves it further into the system.
As the hydraulic fluid flow is restricted while the pump continues to push higher and higher, the fluid pressure will increase due to the hydraulic fluid being incompressible. Thanks to this increasing pressure, hydraulic elements such as lift cylinders, tilt cylinders, and steering cylinders can be extended or retracted, which allows handling the loads efficiently and without much effort.
Gear-type hydraulic pumps are the most common type of Clark forklift hydraulic pump. If you want to learn more about these pumps, watch the following video:
How do I Know if My Clark Forklift Hydraulic Pump is Bad?
It is very rare for a gear hydraulic pump to suddnly and unexpectedly completely fail. Generally, when these devices begin to present some type of failure, it is usually reflected in one way or another. If we keep an eye out for these signals, we can take corrective action right before the pump fails. This will help extend the device's lifespan and save much of our money. Below we will highlight the most common signs or symptoms in Clark forklifts due to a faulty hydraulic pump.

What Causes Clark Forklift Hydraulic Pump Failure?
Worn seals. Over time, the seals in the pump can wear out, causing leakage. This might make the lift truck's forks move more slowly or less responsively.
Leaks. If your Clark forklift hydraulic pump shows signs of a leak, it's crucial to take action immediately. Leaks cause the pump to lose pressure, leading to decreased lifting power.
Hydraulic fluid contaminated. This happens when abrasive particles in the fluid come from repairs, welding slag or wear and tear on seals. And, if the hydraulic filter can't keep these particles out, they will move around freely in the system damaging the rest of the hydraulic parts. This will make the pump less efficient and could eventually take it out of service completely.
What to Do Before Replacing a Clark Forklift Hydraulic Pump
Do you have a new hydraulic pump for your Clark forklift? If so, there are some things you need to do before installing it. To make the most of your new pump and keep it working well for as long as possible, we need first to purge the hydraulic system. This will eliminate any impurities or particles that could damage the system.
Once the system has been purged, we must ensure that there is no type of leak through which the hydraulic fluid can escape. That's why we must check out all the connections. If possible, we should replace or at least check the seals of the hydraulic cylinders as well. We know that sounds like a lot of work, but with these instructions, you can guarantee that everything will go perfectly with your new hydraulic pump.
