Connecting Rod Bearings Undersize -020 for the Villiers MK15 engine are precision bearing shells that support the conrod big-end on the crankshaft. Made from durable metal-backed bearing material for long service life, they restore correct oil clearance and smooth running on engines with a reground crank journal. This genuine Villiers part is suitable for classic Villiers units such as the MK15 and MK15/2 and is supplied as unused old stock, so minor storage marks may be visible but function is unaffected. The -020 designation indicates a 0.020 in undersize (approximately 0.51 mm), intended for use with a crankshaft that has been ground to this size. Ideal for maintenance and restoration of vintage engines used in small plant and garden machinery.
