Description
Overview:
The Big End Shells -010 Undersize are genuine Villiers components designed for JAP 3 and JAP 4 engines. Supplied as a matched pair, these steel-backed bearing shells feature an anti-friction lining to support the crankpin and maintain a stable oil film under load. The -010 undersize (0.010 in / 0.254 mm) is intended for use with crankshafts that have been reground to suit this size, helping restore correct bearing clearance and smooth rotation. Durable and reliable, they are well suited to engine rebuilds and maintenance where original specification matters. These are unused vintage old stock parts and may show light tarnish or storage marks without affecting performance. OEM reference 18474/010 ensures straightforward identification and compatibility with the intended JAP engines.
