495-1507 Exhaust Fluid Filter — Cat 272D 297D

This exhaust fluid filter is crucial for removing contaminants from the Diesel Exhaust Fluid (DEF) system, ensuring clean fluid reaches the SCR catalyst. It prevents impurities from clogging injectors or damaging the DEF pump and catalyst, thereby maintaining optimal emissions control performance. A clogged or failed filter will lead to reduced engine power, DEF system fault codes, and potential non-compliance with emissions regulations.

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 restricted DEF filter include a gradual reduction in engine power and potential DEF system warning lights. If the filter becomes completely blocked, the DEF system may shut down, leading to the engine refusing to start or operating in a derated mode. Failure to address a clogged DEF filter will result in non-compliance with emissions standards and potential operational downtime.

Installation Tip

Ensure the area around the DEF filter housing is clean before removal to prevent dirt from entering the system. Always use a new sealing washer or O-ring when installing the new filter to ensure a leak-free seal.

Service Note

Inspect the DEF tank and lines for any signs of contamination or crystallization when replacing the exhaust fluid filter.
