359-5469-20r-3477 Fuel Injector — Cat Engine 3512C 3516C

This Fuel Injector is a precision component responsible for delivering atomized fuel directly into the combustion chamber of CAT engines. Manufactured to strict tolerances, it ensures optimal fuel spray patterns and precise fuel metering, unlike a worn injector that may leak or deliver inconsistent fuel amounts. Operators may experience rough idling, reduced engine power, increased exhaust smoke, or poor fuel economy when this injector begins to malfunction.

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 injector include rough idling, a loss of engine power, or increased exhaust smoke. If left unaddressed, the engine may begin to misfire, leading to uneven running and potentially damaging the catalytic converter or diesel particulate filter. Continued operation with faulty injectors can result in significant fuel waste and internal engine damage.

Installation Tip

Ensure the injector bore in the cylinder head is perfectly clean and free of any carbon deposits before installing the new injector. Use the specified sealing washers and torque settings precisely.

Service Note

Inspect the fuel lines, fuel filter, and fuel pump for any issues when replacing a fuel injector.
