315-4672 Fuel Injector — Cat 3044C 236B2

This fuel injector is a vital component for the engine's combustion process, delivering a precise spray of diesel fuel into the cylinder at high pressure. Manufactured to meet strict quality benchmarks, it ensures optimal fuel atomization and combustion efficiency, unlike a worn injector that may produce a poor spray pattern. Operators may experience rough idling, increased exhaust emissions, a loss of engine power, and a decrease in fuel economy when this injector begins to fail.

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

A failing fuel injector typically first manifests as a rough or uneven engine idle. If left unaddressed, this can progress to noticeable power loss during operation and increased black smoke from the exhaust due to incomplete combustion. Continued operation risks uneven cylinder wear and potential damage to other engine components.

Installation Tip

Ensure the injector seat in the cylinder head is perfectly clean and free from carbon deposits before installing the new injector. Avoid rotating the injector while tightening the hold-down bolt, as this can damage the seal.

Service Note

When replacing a fuel injector, it is recommended to replace the fuel filter and inspect the fuel lines for any signs of leaks or damage.
