351-8940-317-6389 Fuel Injection Pump — Cat TH337C TH336C

This is a fuel injection pump, a critical component responsible for delivering precisely metered fuel to the engine cylinders under high pressure. Manufactured to meet CAT's exacting specifications, it ensures optimal fuel atomization and combustion efficiency, unlike a worn pump that can cause rough running or poor fuel economy. Operators may experience a loss of engine power, rough idling, increased exhaust smoke, or difficulty starting the engine when 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 can include a subtle decrease in engine performance or slightly rougher idling. If not addressed, the pump may begin to deliver fuel inconsistently, leading to significant power loss, excessive smoke, and potential engine stalling.

Installation Tip

It is crucial to ensure the fuel system is completely free of air after installation to prevent running issues. Never reuse old fuel lines or fittings, as they can introduce contaminants or leaks.

Service Note

Always replace the fuel filter and inspect fuel lines when servicing the fuel injection pump.
