Description
Overview:
The Governor Crank Bush for Villiers C12 engines is a small machined metal bearing that supports the governor crank pivot, helping the governor to control engine speed smoothly and reliably. Supplied as a Genuine Villiers part, MPN EM2109, it is suitable for classic stationary engines commonly found on garden and construction machinery. This bush replaces worn or ovalised originals to remove play and restore accurate governor response, improving idle stability and load regulation. Made to the correct pattern and tolerances for Villiers applications, it fits directly without modification. Ideal for maintaining vintage engines such as the Villiers C12 and MK12, this unused old stock item may show minor tarnishing from storage, which does not affect performance or service life when installed correctly.
