One New Aftermarket Replacement Potentiometer Assembly (Throttle Knob) for Komatsu Excavators and Wheel Loaders

This aftermarket replacement potentiometer assembly -- also commonly called a throttle knob or throttle regulation resistance switch -- mounts in the cab console and controls engine speed (RPM) on Komatsu hydraulic excavators and wheel loaders. The potentiometer sends a variable resistance signal to the engine controller, allowing the operator to dial in throttle position for different job site conditions.
