Perkins original 196-4229 Diesel Fuel Injector Assembly Stainless Steel 3126 Series Aftermarket Parts For Construction Engines 10R0782 new injector original new injector

Engineered as a direct replacement for Perkins 3126 series HEUI diesel engines, fuel injector 196-4229 is built to match the original fuel system architecture, injector body dimensions, nozzle characteristics, electrical connection interface, and hydraulic actuation requirements of Perkins 3126, 3126B, 3126E, and related 3116 platforms. The authorized OE number 196-4229, together with reman references 0R-9350, 0R9350, and OR9350, confirms OEM-equivalent fit and function for service shops, fleet operators, and engine rebuilders working on medium-duty truck engines, vocational equipment, generator sets, and industrial diesel applications.

The injector operates through HEUI technology, where high-pressure engine oil hydraulically actuates the unit while the ECM manages electronic injection timing and fuel delivery. This combination supports precise fuel metering and atomization under varying load, speed, and temperature conditions, improving torque response, idle quality, cold-start behavior, and overall fuel economy. Every unit is flow tested, spray tested, leak tested, and solenoid tested, and remanufactured units are supplied with 100% new O-rings and surface-lapped critical sealing components to ensure sealing integrity and long-term reliability.

Compatible with cross numbers 10R-9239, 141-7837, 169-7410, 173-1013, 173-9272, 222-5972, EX639350, AP63922, and 175-9272, this injector serves heavy-duty operating environments including long duty cycles, stop-and-go trucking, dusty job sites, and variable fuel quality. Proper installation can help restore engine smoothness, reduce misfire, lower exhaust smoke, stabilize fuel consumption, and bring the engine back to expected performance. Always use clean diesel fuel meeting Perkins specifications, maintain correct engine oil grade and pressure, inspect injector harnesses and connectors, and replace fuel filters and injector seals during service.
