Q1: Why is my PC200-7 engine not responding to the throttle dial?
A: This is commonly caused by a burnt-out internal motor or damaged gears in the 22U-06-11790 assembly. Check the wiring harness first; if the signal is reaching the motor but it fails to rotate, a replacement is required.
Q2: How do I handle the E02 Error Code on a Komatsu Excavator?
A: E02 usually indicates a TVC valve or throttle motor feedback error. Replacing the old unit with our 201-43-72122 OEM standard motor ensures the controller receives the correct voltage signal, clearing the fault.
Q3: Why Choose This Throttle Motor?
A: Our units feature an OEM-standard tri-metal structure and are trusted by repair shops and equipment fleets worldwide for their reliability in harsh construction environments.
Beyond throttle motors, we specialize in comprehensive engine components for Cummins, Komatsu, Caterpillar, Isuzu, Kubota, Yanmar, and Weichai engines. We provide complete engine assemblies and precision-engineered spare parts.
