What Does a Hydraulic Pump Do?

The main hydraulic pump converts engine power into pressurized oil flow. That oil moves the boom, arm, bucket, swing and travel functions, so every machine movement depends on it. Because it takes the most punishment, it is usually the first major hydraulic component to wear out.

Signs the Part Needs Replacing

  • Slow or weak movement on all functions: when everything is slow at once, not just one circuit, the pump is the most likely source.
  • Whining, knocking or grinding noise: internal wear or cavitation, especially on start-up or when the oil is cold.
  • Hydraulic oil running hot: internal bypass leakage turns pressure into heat.
  • Metal particles in the filter or case drain: a failing pump sheds metal and pushes out more case drain flow.
  • Erratic or spongy movement, foamy oil: air entering the suction line, or aeration, upsets pump flow.

These symptoms overlap with clogged filters, low oil, air in the suction line and worn valves, so check the filters and oil level before replacing the part.

How to Order and Install the 20/925586 Hydraulic Pump

  • Confirm your machine model, the part number and the pump model on your existing pump before ordering.
  • Send a photo of the old pump or the nameplate if you are not sure; LIONKITS will confirm fitment for you.
  • Change the hydraulic oil and the return filters before fitting the new pump; a new pump installed in contaminated oil will fail early.
  • If the old pump failed internally and shed metal, flush the tank, hoses and oil cooler and inspect the control valve and motors for contamination.
  • Fill the pump case with clean hydraulic oil and prime the pump as the service manual specifies before the first start.
  • Check the suction line, strainer and fittings for air leaks, and tighten bolts to the specified torque.
  • Run the machine at low speed first, then check pressure, noise and leaks.

Shipping, Payment and Support

  • Dispatch and delivery: Your package will be sent within 2-3 business days, and another 3-7 business days to arrive in your country
  • Payment methods: Credit Card, PayPal, T/T, Western Union
