293-4072 Fuel Injector — Cat 330D 336D

This fuel injector is engineered to deliver a precise spray pattern and volume of diesel fuel into the combustion chamber of CAT C9 engines, essential for efficient power generation. Built to OEM quality standards, it ensures consistent fuel atomization, unlike a worn injector that might dribble or spray unevenly. Observable symptoms of a failing injector include rough idling, reduced engine power, increased black smoke, and potential engine misfires.

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 may initially manifest as a slight roughness in engine idle or a minor reduction in power. If left unaddressed, the issue can lead to significant performance loss, increased fuel consumption, and potential engine damage due to uneven combustion.

Installation Tip

Ensure the injector bore in the cylinder head is meticulously clean before installing the new injector. Avoid applying excessive force when seating the injector, as this can damage the sealing surfaces.

Service Note

Inspect the fuel rail pressure and the fuel filter for any signs of contamination or blockage that could affect injector performance.
