The arm pivot bush is a small but critical wear component located at the pivot point of a linkage arm — typically within the governor or throttle control assembly on Honda GX240 and GX340 engines. Its job is to provide a low-friction, dimensionally stable bearing surface that allows the arm to rotate or oscillate without play or binding. When this bush wears, the pivot develops slop, which can cause inconsistent throttle response, governor instability, or uneven engine speed under load — problems that directly affect generator output quality or welder arc stability. Replacing a worn bush promptly restores precise linkage movement and protects the surrounding arm and pin from accelerated wear.
