107-3651-10r-7589 Fuel Injector — Cat 3046 933

This fuel injector is a precision component responsible for atomizing and delivering fuel into the engine's combustion chamber at the correct time and pressure. Manufactured to exact specifications, it ensures optimal fuel atomization and spray pattern, unlike a worn injector that may leak or clog. Operators might observe rough idling, black smoke from the exhaust, a loss of engine power, or increased fuel consumption when this fuel injector is malfunctioning.

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 can initially manifest as rough engine idling or a noticeable decrease in engine power. If ignored, the problem may progress to persistent black smoke from the exhaust and significantly increased fuel consumption. Continued operation with faulty injectors risks incomplete combustion and potential damage to engine components.

Installation Tip

Thoroughly clean the injector bore in the cylinder head before installing the new injector to prevent leaks or damage. Ensure the sealing washer is correctly seated and torqued to specification to avoid fuel leaks.

Service Note

Inspect the fuel filter, fuel lines, and engine compression when replacing a fuel injector.
