Williams Controls 400467 Throttle
Selecting a Williams Controls 400467 throttle requires more than matching a number in a catalog. This assembly is used in heavy-duty and off-highway equipment where the pedal must translate foot pressure into a stable electrical command. A replacement that fits mechanically but sends the wrong output can cause hesitation, a dead pedal, or dangerous idle behavior. The following checks help you evaluate compatibility, condition, and signal quality before you spend money or take the vehicle out of service.
The direct answer
The direct answer is that the 400467 Williams Controls is an electronic throttle pedal or throttle position assembly intended for specific commercial and industrial applications, not a universal part. Before purchasing, compare the mounting bolt pattern, lever shape, connector pinout, and cable length with the unit already installed. Even visually similar pedals can use different resistance curves or voltage outputs, and a mismatch may make the engine controller reject the signal or interpret partial travel as full throttle.
Treat the full 400467 Williams Controls marking on the housing as the starting point, then verify the electrical connector and any secondary identification numbers. Because this component often controls engine speed in stationary equipment as well as on-road vehicles, orientation and stop points matter. A correct replacement should return smoothly through its travel and produce a steady signal without dropouts. If the connector is damaged or the wiring has been spliced, the pedal assembly may need more than a simple swap.
