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

Initial signs of a failing fuel injection pump often include a noticeable decrease in engine power and increased smoke from the exhaust. If left unaddressed, the engine may begin to misfire, run rough, or become increasingly difficult to start. Continued operation with a faulty pump can lead to uneven cylinder loading and potential damage to other fuel system components.

Installation Tip

Ensure the engine's timing is correctly set before installing the new pump to prevent internal damage. Avoid overtightening the mounting bolts, as this can distort the pump housing.

Service Note

Always replace the fuel filters when replacing the fuel injection pump to prevent contamination of the new unit.
