Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial symptom of a failing hydraulic pump body is often a subtle decrease in hydraulic system performance or minor external leaks. If left unaddressed, internal wear or cracks can lead to significant loss of hydraulic pressure and flow, causing components to operate slowly or not at all. This can render the equipment inoperable and potentially damage other hydraulic components due to lack of lubrication or pressure.

Installation Tip

Thoroughly clean all mating surfaces of the hydraulic pump housing and the new body before assembly to ensure a proper seal. Never use abrasive materials that could scratch the precision surfaces where seals and pistons operate.

Service Note

Replace all seals and O-rings associated with the hydraulic pump assembly, and inspect the piston and cylinder block for wear or damage.
