Perkins original Perkins 4P-9077 Common Rail Diesel Fuel Injector for 3516 3512 3508 Engine, Replacement for OEM new injector original new injector

The Perkins 4P-9077 fuel injector is engineered as an OEM replacement component for the Perkins 3512A and C3512A V12 turbocharged diesel engines, serving heavy-duty industrial power generation, marine propulsion, and mining applications. Designed with a precision multi-hole spray tip nozzle, this injector delivers high-pressure fuel atomization up to 2500 bar, ensuring uniform spray patterns that promote efficient diesel combustion and consistent engine performance under demanding load conditions.

Constructed from high durability steel alloy and finished with heat-resistant and anti-corrosion coatings, the 4P9077 injector meets OEM specification compliance for the 3500 Series industrial diesel engine platform. It is compatible with selected 3500 Series configurations and is cross-referenced under authorized numbers including 0R-2925, OR-2925, 236-8241, and 10R-7227, allowing direct fitment across generator sets, cargo ships, tugboats, offshore support vessels, mining trucks, drilling rigs, excavators, and oilfield power units.

Routine maintenance recommendations include inspection for leaks every 500 operating hours, regular fuel filter cleaning or replacement, monitoring of exhaust smoke, and diagnostic bench testing according to engine maintenance schedules. Common indicators of injector wear include hard starting, black or white smoke, power loss, misfire, rough idle, excessive fuel consumption, engine knocking, and fuel leakage. Operators should use only recommended industrial-grade diesel fuel to maintain long-term injector reliability.
