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

Initial signs of a failing hydraulic piston include a gradual reduction in the speed and power of hydraulic functions. If left unaddressed, the pump may start to make abnormal noises, and hydraulic system performance will continue to degrade. Continued operation risks damage to other hydraulic components due to insufficient pressure or contamination.

Installation Tip

Ensure the hydraulic system is thoroughly flushed and clean before installing new pistons to prevent contamination. Avoid mixing old and new parts within the same pump assembly, as this can lead to uneven wear.

Service Note

When replacing hydraulic pump pistons, it is highly recommended to inspect and replace all associated seals, O-rings, and potentially the hydraulic fluid and filter.
