Description
Overview:
The Villiers MK20/MK25 US 020 Big End Shells are genuine Villiers bearing shells for the connecting rod big end on classic Villiers petrol engines. Built from durable bearing‐grade metals, these precision shells support a stable oil film between the conrod and crankpin to reduce friction and wear. Supplied as a matched pair to service one conrod, they are sized US 020, meaning 0.020 in undersize (approx. 0.51 mm) for use with a correctly reground crankpin. Ideal for maintaining and restoring Villiers MK20 and MK25 engines used in small plant and garden machinery. As vintage new old stock, they are unused but may show light age-related tarnish. Genuine Villiers quality helps ensure reliable running, smooth operation, and long service life.
