Description
Overview:
The Packing Shim for Crankshaft Main Bearing is a genuine Villiers OEM component for classic Villiers engines, including MK20 and MK25. Made from precision steel, this thin shim is used to set the correct spacing for the crankshaft main bearing, helping to control end-float and maintain accurate shaft alignment. Correct clearances reduce vibration and wear, supporting stable running and protecting the bearing surfaces. This part is suitable for service and restoration work on small stationary engines commonly used in garden machinery, compact plant, pumps, and generators. Supplied as unused old stock, it is original-period Villiers supply; light tarnishing from age may be present and is normal. Using the correct shim during assembly helps the engine perform reliably and prolongs component life.
