293-3645 Hydraulic Oil Filter — Cat C15 C18

This is a high-efficiency hydraulic oil filter designed to remove contaminants from the hydraulic fluid system. Manufactured with premium filter media, it ensures clean oil flow, protecting vital hydraulic components from wear and damage, unlike a clogged or bypassed filter that allows debris to circulate. Operators may notice sluggish hydraulic functions, erratic operation, or whining noises from the hydraulic pump when this filter is nearing the end of its service life.

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 common indicator of a failing hydraulic oil filter is a decrease in the speed or responsiveness of hydraulic functions. This can progress to jerky movements, system overheating, or audible noise from the hydraulic pump. If the filter bypasses or is not replaced, internal hydraulic components can suffer accelerated wear.

Installation Tip

Ensure the filter housing surface is clean and free of old gasket material before installing the new filter. Lightly lubricate the new filter's rubber gasket with clean hydraulic oil.

Service Note

Inspect the hydraulic oil for signs of contamination or degradation, and check the hydraulic fluid level when replacing the hydraulic oil filter.
