Cummins 3076132 Fuel Injector Assembly

The Cummins 3076132 is a Step Timing Control (STC) fuel injector designed for high-horsepower K-series diesel engines including KTA38, K38, KTA19, K19, KTA50, and K50 configurations. It utilizes a PT (Pressure-Time) fuel system architecture with electronic timing actuation for precise fuel metering and combustion control. Constructed with a high-speed steel nozzle body and hardened alloy steel internal components, the injector withstands peak injection pressures exceeding 100 MPa. The assembly integrates a solenoid valve for electronic timing advance, compatible with 24V DC engine control modules. Critical wear surfaces are precision ground to maintain spray pattern integrity over extended service intervals. Primary OEM cross-references include Cummins 3058802, 3077715, 3095773, 3652514, and 3076703. Interchangeable with aftermarket designations INJ-101863-CMN (New) and INJ-101863-CMR (Remanufactured). Verified fitment spans XCMG rotary drilling rigs, SANY excavators, Komatsu mining equipment, Terex haulers, marine propulsion packages, and stationary generator sets powered by Cummins K-series engines.
