Description
Overview:
The Governor Gear for JAP 444H and 444H-2 industrial engines is a genuine JAP component designed to regulate engine speed accurately. Made from durable steel, it forms part of the centrifugal governor system, transferring motion to control throttle position and keep RPM stable under varying loads. Correct governor action protects the engine from over‐speed and hunting, improving performance and service life. This unused old‐stock vintage part may show light tarnishing from storage, but it remains fully serviceable. It is suitable for workshop overhauls and in-field repairs on plant and machinery powered by JAP 444H and 444H-2 engines, such as generators, pumps, mixers, and compactors. Supplied as a direct replacement for OEM specification 19580/2, it helps restore reliable speed control with OEM fit and function.
