Installation & Application Notes

Never run an engine without a filter — even briefly causes abrasive damage. Pre-fill fuel filters with clean fuel before fitting to reduce prime time. Replace O-rings on filter housings every second service. Record change dates on filter housing.

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

Failure Symptoms

A failing hydraulic filter may initially present as sluggish hydraulic operation or slight overheating of the fluid. If left unaddressed, internal wear on hydraulic components will accelerate, leading to inconsistent performance and potential leaks. Continued operation with a contaminated system risks severe damage to the hydraulic pump and other precision parts.

Installation Tip

Ensure the hydraulic system is properly depressurized before attempting to remove the old filter element. Do not reuse the old O-ring or seal, as this can lead to leaks and contamination.

Service Note

When replacing the hydraulic filter, inspect the hydraulic fluid for signs of contamination or degradation and check the condition of the return line screens.
