141-6189 4 Pcs Fuel Injector — Cat 3054 M312

This set of four fuel injectors is a precision-engineered engine component that atomizes and injects fuel into the combustion chambers at the correct time and pressure. Manufactured to exact specifications, these injectors ensure optimal fuel atomization and combustion efficiency, unlike worn injectors that can cause poor spray patterns and incomplete burning. Operators may experience rough idling, reduced engine power, increased fuel consumption, or excessive smoke if these injectors 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

Early signs of failing fuel injectors can include uneven engine running, a slight decrease in power, or increased exhaust smoke. As the condition progresses, these symptoms will intensify, leading to noticeable rough idling, significant power loss, and potentially increased fuel consumption. Continued operation with faulty injectors risks incomplete combustion, leading to potential engine damage and increased emissions.

Installation Tip

Ensure the injector seats in the cylinder head are perfectly clean and free of carbon deposits before installing the new injectors. Use new copper sealing washers and do not overtighten the injector hold-down bolts.

Service Note

Inspect the fuel lines for leaks and clean the fuel filter when replacing fuel injectors.
