Perkins original Perkins 961-4357 Fuel Injector OEM-Standard Kit for 3512A Engine Construction Machinery  original new injector

Engineered for the demanding conditions of heavy-duty diesel operations, the Perkins 3512A fuel injector part number 961-4357 is a precision-manufactured replacement component designed to restore original engine performance. It is directly compatible with Perkins 3508, 3508B, 3512, 3512A, 3512B, 3516, 3516B, and 3516C engines, and is widely applied across generator sets, marine propulsion systems, mining trucks, oilfield power equipment, industrial power plants, construction machinery, offshore energy platforms, and rail power systems.

Constructed from heat-treated alloy steel material, this injector delivers high temperature resistance and corrosion resistance, ensuring long service life even in extreme operating environments. The high-pressure electronic fuel injection design is factory calibrated to OEM specification precision grade and individually performance tested to guarantee consistent spray pattern, optimized fuel consumption, and low emissions performance. Its direct replacement installation allows for seamless integration without modification.

The injector serves as an OEM equivalent and cross-references with 0R-8479, 10R-0957, 211-3028, and 217-2570, making it a versatile solution for fleet operators and service workshops. Routine maintenance using clean diesel fuel, regular filter replacement, injector balance rate monitoring, and periodic engine diagnostics will help prevent fuel delivery faults, cylinder misfire, injection timing error, fuel pressure imbalance, and combustion efficiency loss. Always verify the injector part number, clean the injector bore thoroughly, replace sealing washers, inspect fuel lines, and follow Perkins service manual procedures and torque specifications for reliable operation.
