Engineered as a direct replacement for HEUI-equipped 3126 family and C7 diesel engines, this 10R-0781 fuel injector delivers precision-controlled fuel delivery for medium-duty and industrial diesel applications. The injector cross-references to 197-7107, 198-6605, 199-6065, 222-5966, 222-5926, EX630781, CA10R0781, CA1977107, CA1986605, CA1996065 and CA2225966, giving procurement teams broad interchangeability across 3126B, 3126E and C7 HEUI platforms. A complete 6-cylinder engine service requires six injectors per engine, and the unit is available as a single injector, a 6-piece full engine set, or wholesale batches with an optional core exchange program.
As a Hydraulic Electronic Unit Injector, the 10R-0781 operates under ECM control, calculating injection timing and duration from engine speed, coolant temperature, intake temperature, throttle position, boost pressure and injection actuation pressure. High-pressure engine oil acts on the intensifier piston to elevate fuel pressure for atomized delivery. Correct operation helps address rough idle, misfire, hard starting, low power, excessive smoke and abnormal fuel consumption. Typical symptoms of 10R-0781 failure include rough idle, misfire during acceleration and higher fuel consumption, which can be verified through diagnostic scanning.
Applications include Freightliner, Ford, GM, International, Kenworth and Western Star trucks, plus school buses, motorhomes, marine vessels, fire trucks, cranes, agricultural equipment, forestry machines, forklifts, irrigation and mining power units. Before installation, verify injector code, ECM calibration and engine serial number, replace all seals and O-rings, and follow official priming and torque procedures.
