Perkins original Perkins 961-4357 Diesel Engine Parts Fuel Injector Replacement for OEM 3512A Construction new injector original new injector

The 961-4357 fuel injector is engineered as a direct OE replacement for Perkins 3512A diesel engines, manufactured to meet original equipment performance and dimensional standards. This injector carries full cross-reference compatibility with 0R-8479, 10R-0957, 211-3028, and 217-2570, allowing seamless interchange across Perkins 3508, 3508B, 3512, 3512A, 3512B, 3516, 3516B, and 3516C engine platforms. Built from heat-treated alloy steel with high temperature and corrosion resistance, the assembly is factory calibrated and 100% performance tested to ensure precise fuel metering, optimized fuel consumption, and low emissions output under continuous heavy-duty operation.

Designed for demanding industrial environments, the 961-4357 injector supports generator sets, marine propulsion systems, mining trucks, oilfield power units, offshore energy platforms, construction machinery, and rail power systems. Its high-pressure electronic fuel injection design delivers consistent atomization and stable injection timing, addressing common fault conditions such as cylinder misfire, fuel pressure imbalance, injection timing error, and combustion efficiency loss. The component installs as a direct replacement without modification, restoring factory-rated engine performance and reliability across global Perkins 3500 series applications.

Proper maintenance extends service life and protects injection system integrity. Operators should use clean diesel fuel, replace filters at scheduled intervals, inspect fuel lines, monitor injector balance rates, clean the injector bore thoroughly, and replace sealing washers during installation. Periodic engine diagnostics and ECM fault code verification are recommended, and all service work should follow Perkins service manual procedures and torque specifications. Confirming the part number 961-4357 against engine records before installation ensures correct fitment and prevents compatibility issues across the 3500 series engine range.
