original 10R-9237 178-0199 177-4754 Diesel Injector Pump Engine Spare Parts for 3126E E325C 962G new injector original new injector

Engineered specifically for the 3126, 3126B, and 3126E HEUI platform, this fuel injector 10R-9237 delivers precise fuel metering, high-pressure atomization, and reliable electronic solenoid response required by the 7.2L inline six-cylinder medium-duty diesel engine. The HEUI system combines ECM-controlled injection timing with hydraulically driven actuation, using pressurized engine oil to operate the internal piston and plunger. This construction enables accurate control of injection timing, fuel quantity, cold starting, warm-up behavior, smoke output, fuel economy, and overall engine response across on-road trucks, buses, RVs, and off-road machinery such as the 938G II loader, 953C and 963C track loaders, and 322C and 325C excavators.

The injector is remanufactured to meet OE-level flow, leakage, and spray pattern specifications, with hardened internal components designed to withstand sustained high-pressure operation. Each unit is individually flow tested, leakage tested, and spray pattern inspected before dispatch. Supply options include a single injector or a complete set of six, packaged in clean sealed containers suitable for B2B export to diesel repair shops, fleet maintenance centers, engine rebuilders, agricultural and construction machinery distributors, and global aftermarket parts sellers. Cross-reference coverage includes 10R9237, 177-4754, 178-0199, 10R-0782, 10R-1257, 178-6342, CA10R9237, CA10R1257, CA1786342, M-1774754, R-10R0782, 390094X, and 390094EX.

Before installation, confirm the original injector part number, engine serial number, engine arrangement number, and machine model. Clean and inspect the fuel system for contamination, replace fuel and oil filters, check the HEUI high-pressure oil system, install new seals and O-rings, and inspect injector sleeves for wear or carbon damage. Follow the official service manual for torque values. After installation, scan the ECM for fault codes, monitor cylinder balance data, and verify injection actuation pressure. Maintain clean diesel, scheduled filter changes, clean engine oil, and protected electrical connectors to maximize service life.
