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 filter may initially present as slightly slower hydraulic response or a faint whining noise from the pump. If left unaddressed, the system can experience overheating, increased component wear, and potential loss of hydraulic function. Continued operation risks severe damage to pumps, valves, and cylinders.

Installation Tip

Ensure the filter housing seal surface is clean and free of debris before installing the new filter element. Do not reuse the old seal; always install a new one to guarantee a proper seal.

Service Note

Inspect the fluid for signs of contamination or degradation and check the condition of the filter housing seals during filter replacement.
