original 374-0750 Diesel Fuel Injector Assy for C15 C18 C27 C32 Excavator Engine Fuel Injection Nozzle 3740750 20R-1304 20R-2284 359-7434 Replacement original new injector

Engineered for demanding off-highway operations, the 374-0750 diesel fuel injector is a heavy-duty electronic unit injector supporting C15, C15 ACERT, C18, C27 and C32 industrial engine platforms. Cross-referenced under 3740750, 20R-2284, 20R-1914, 10R-3264, 253-0615, 244-7715, 235-1401, 618-0750 and PAI 390088X, this injector GP fuel assembly is widely deployed across mining trucks, wheel loaders, motor graders, track-type tractors, off-highway haulers, petroleum packages and stationary power generation systems.

The injector delivers a precisely metered diesel charge at the correct timing event, promoting fine atomization, complete combustion, cylinder-to-cylinder balance and stable rated power under continuous heavy load. Operators benefit from improved combustion efficiency, reduced black and white smoke, lower fuel waste and consistent performance in construction, mining, hauling, marine, rental fleet and engine rebuild applications. Broad cross-reference coverage, including CA3740750, CA20R2284, CA6180750, R202284, R-20R2284, P346317R and remanufactured 20R-2284R / 20R-1914R / 10R-3264R variants, supports global aftermarket sourcing for equipment such as 770G, 777G, 980H, D8T, 992K, 854K, 6030, 6040 FS, R2900G and R3000H.

To maximize injector service life, use clean diesel fuel, service fuel filters, drain water separators, monitor ECM fault codes and inspect for leakage, misfire or abnormal smoke. Confirm 374-0750 compatibility by engine serial number and arrangement, clean the injector bore, install new seals, torque to service manual specification, verify injector coding and perform post-installation leak and performance testing. Replacing injectors as a complete set is recommended to maintain atomization balance.
