Description
Overview:
This governor friction plunger is a small, machined metal component used to stabilise and control engine speed in vintage JAP industrial engines. Fitted within the governor mechanism, it provides frictional damping so the governor can hold a steady idle and governed top speed under changing load. Built from robust materials for long service life, it is suitable for classic engines such as the JAP 4 and JAP 5 commonly found in light plant and stationary equipment. This is a Genuine JAP part with OEM reference 14772, supplied as unused old stock. As with many NOS items, minor tarnish or storage marks may be present, but performance is unaffected. It is ideal for restoration and maintenance where correct fit and period-correct function are important.
