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

A clogged hydraulic oil filter will first manifest as a noticeable slowdown in hydraulic system response and potentially increased operating temperatures. If the filter becomes completely blocked, the bypass valve will open, allowing unfiltered oil to circulate, leading to rapid wear of hydraulic components. This can result in expensive repairs to pumps, cylinders, and valves.

Installation Tip

Always lubricate the rubber gasket on the new filter with clean hydraulic oil before installation to ensure a proper seal and prevent damage. Ensure the filter mounting surface is clean before screwing on the new filter.

Service Note

When replacing the hydraulic oil filter, it is also recommended to inspect the hydraulic fluid for signs of contamination or degradation.
