Kobelco 20S00003F3 Throttle Motor Assembly

The 20S00003F3 throttle motor is a 24V DC stepper motor actuator designed for electronic engine speed governance on Kobelco hydraulic excavators. It functions as the throttle actuator motor governor, translating ECU signals into precise mechanical throttle plate positioning. Constructed with a sealed housing for environmental resistance against dust, vibration, and moisture typical in construction machinery applications. The unit features an OEM-style electrical connector for direct plug-and-play installation. It replaces the original equipment throttle motor assembly on specified Kobelco models.
