Crown Potentiometer – CR146565-002

Potentiometers act as the electrical translator between operator input and a lift truck's control system, converting a physical motion, a twist of a dial, the travel of a foot pedal, or the throw of a lever, into a variable resistance signal the controller can read and act on. Crown builds this potentiometer for its lift truck line, where potentiometers like it are commonly used to relay speed, lift, or directional commands from the operator's controls to the truck's electronics.

Because the signal depends on a wiper sliding across a resistive element, wear is built into how the part works. Repeated cycling gradually abrades that contact surface, and a worn or dirty potentiometer starts sending an inconsistent or noisy signal instead of a clean one, which the controller reads as erratic input even when the operator's motion is smooth. That shows up as jerky response, dead spots, or a function that behaves differently at the same control position from one moment to the next.

Replacing the potentiometer restores an accurate, repeatable signal so the controller gets a true reading of operator input. At 0.05 pounds, this is a small precision component, built to Crown's mounting and shaft specification for direct fitment into the control assembly it serves.
