The Perkins 10R-0782 HEUI fuel injector is engineered for Perkins 3126, 3126A, 3126B, and 3126E series diesel engines, covering excavator, wheel loader, truck, generator set, and industrial power applications. As a Hydraulically actuated Electronically controlled Unit Injector, it receives electronic commands from the ECM while high-pressure engine oil drives mechanical actuation, then meters, pressurizes, and atomizes diesel fuel directly into the combustion chamber for clean, efficient combustion.

This remanufactured replacement injector supports precision fuel metering, restored engine power, smoother idle operation, reduced fuel knock, and improved fuel economy across heavy-duty working cycles. It is cross-referenced to 178-0199, 178-0198, 177-4754, 205-1285, EX630782, 10R-9237, R10R0782, FS10R0782, TDM10R0782, and related part numbers, allowing direct fitment on Perkins 322C, 325C, M325C, 950G II, 962G II, IT62G II, 570B, 580B, and similar equipment. Extensive testing and critical engineering updates deliver like-new operating performance at a lower repair cost than a full new unit.

Reliable long-term operation depends on clean diesel fuel, scheduled fuel and oil filter replacement, proper water separator draining, and correct engine oil quality, since HEUI injectors rely on high-pressure oil for actuation. Always inspect electrical connectors and harnesses for intermittent faults, and replace O-rings and seals with new lubricated seals each time the injector is removed. Remanufactured cores should be returned complete and undamaged in accordance with the supplier core policy.
