Description
Overview:
Genuine Villiers big end bearing shells, supplied as a matched pair, to fit Villiers C45 engines. These steel-backed shells have a precision-finished bearing surface to restore correct oil clearance on a reground crankpin. They are undersize 0.020 in (0.51 mm), often called "20 thou," and are intended for engines where the crankshaft journal has been machined accordingly. Made for vintage Villiers machinery, they help recover smooth running, oil pressure, and service life after wear. Ideal for classic engine rebuilds in the workshop or garage, they provide a direct-fit replacement for the original parts on the C45. OEM reference 31167 confirms authenticity. As unused old stock, the shells are functionally new but may show light tarnish or storage marks typical of period components.
