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 delay in hydraulic response or a faint whining sound from the pump. If left unaddressed, the filter will restrict flow, leading to reduced hydraulic power and potential overheating. Continued operation with a severely blocked filter can cause premature wear on hydraulic components.

Installation Tip

Ensure the filter housing O-ring is properly lubricated before installing the new filter. Do not overtighten the filter, as this can damage the threads or the seal.

Service Note

Inspect the hydraulic fluid for contamination and check the condition of the hydraulic pump and cylinders when replacing the filter.
