351-0973 Fuel Injection Pump — Cat M316D M318D

This is a Fuel Injection Pump, responsible for delivering pressurized fuel to the engine's injectors at the precise moment required for combustion. It is manufactured to exacting standards to ensure accurate fuel metering and high-pressure delivery, unlike a worn or faulty pump. Operators may experience rough idling, loss of engine power, increased fuel consumption, or difficulty starting the engine if this pump fails.

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 symptoms of a failing fuel injection pump often include rough engine idling and a noticeable decrease in overall engine power. If the problem persists, fuel consumption may increase, and starting the engine can become difficult or impossible. The ultimate consequence is a complete loss of engine power, rendering the equipment inoperable.

Installation Tip

Ensure the fuel system is thoroughly purged of air after installing the new pump to prevent operational issues. Always use new fuel filters when replacing the injection pump to protect the new component from contamination.

Service Note

Replace the fuel filters and inspect the fuel lines and injectors for any signs of leaks or wear when installing a new fuel injection pump.
