Applicable Models & Applications
This pump serves fuel systems on Komatsu engines and equipment, delivering and metering fuel to the injection system and holding pressure during operation and restart. Suitable for the corresponding machine model and configuration — please verify the machine model, serial number and part number match before ordering.
Maintenance & Replacement
Keep the pre-filter and fuel filter clean, fuel dry, and check the pump's delivery pressure at the specified interval; a restricted filter makes the pump work harder and shortens pump life. Early signs it may need attention: Hard starting, especially after the machine has sat, is often the first tell the pump is losing prime; A persistent low-pressure code or weak fuel delivery under load points at a tired pumping element; Aerated fuel from a loose suction fitting makes the engine stumble and smoke.
Installation Essentials
Work on a clean machine with the engine off and the relevant system drained or depressurised as required, and confirm the part number against your machine model and serial number before ordering. Always fit new seals and bleed the system completely; trapped air is a common cause of a 'new' pump failing. Run the correct fuel grade — thick, waxy fuel in cold weather overloads the pump. After installation, run the machine and check for leaks, unusual noise or abnormal travel before returning it to service, and retighten where the manual calls for it after the first hours of operation.
