162-8811-20r-1276-0r-8893 Fuel Injector — Cat 3512 3516

This is a fuel injector, a critical component in the engine's fuel system responsible for precisely atomizing and delivering fuel into the combustion chamber. Manufactured to meet stringent OEM quality standards, it ensures optimal fuel spray patterns and flow rates, unlike a worn injector that may cause poor combustion and reduced efficiency. Observable symptoms of a failing injector include rough idling, loss of engine power, increased exhaust smoke, and a noticeable decrease in fuel economy.

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 a faulty fuel injector include engine misfires, particularly noticeable at idle, and a slight increase in exhaust smoke. If the issue progresses, the engine will experience significant power loss, rough running, and potentially increased fuel consumption. Unaddressed, a severely malfunctioning injector can lead to cylinder wash-down, piston damage, and potential engine failure.

Installation Tip

Ensure the injector seat in the cylinder head is perfectly clean and free of any debris before installation. Avoid using excessive force when tightening the injector hold-down clamp, as this can damage the injector body.

Service Note

Inspect the fuel filter and lines for contamination, and consider replacing the glow plugs if equipped when servicing fuel injectors.
