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

Early signs of a clogged hydraulic filter include a slight hesitation or sluggishness in hydraulic functions. As the filter becomes more restricted, pump cavitation may occur, leading to increased noise and potential damage. If the filter bypasses due to extreme clogging, unfiltered contaminants will circulate, causing rapid wear to hydraulic components.

Installation Tip

Ensure the filter housing is clean before installing the new filter and that the new gasket is properly seated. Do not overtighten the filter, as this can damage the seal or the housing.

Service Note

Inspect the hydraulic oil level and condition, and check for any signs of wear or damage in the hydraulic pump and cylinders.
