Product Description
The Bendix 550403 ET-2 Electronic Throttle Pedal Major Repair Kit is designed for servicing compatible Bendix ET-2 electronic accelerator assemblies used in heavy-duty commercial vehicles with Caterpillar electronic engine controls. This genuine Bendix repair kit provides replacement components for restoring the operation of an existing electronic throttle assembly without replacing the entire accelerator unit.
The Bendix ET-2 electronic throttle system converts driver accelerator pedal movement into an electrical signal that communicates throttle demand to the engine's electronic control system. Proper operation of the pedal mechanism is essential for smooth acceleration, dependable throttle response, and accurate engine speed control.
The 550403 major repair kit is intended for compatible ET-2 electronic throttle assemblies, including original Bendix numbers 5002574 and 5009751. It provides a service option for repairing worn or damaged throttle components while retaining the existing assembly where appropriate.
