Description
Overview:
These Big End Shells (Standard) are genuine Villiers components for JAP 6 engines, supplied under Manufacturer Part Number 18475. They are precision-made metal bearing shells that fit the big end of the connecting rod to support the crankpin, maintain an oil film, and reduce friction under load. As a standard size set, they are intended for crankshafts ground to original specification rather than undersize or oversize journals. Ideal for maintaining or restoring JAP 6/JAP6 engines found in vintage machinery, they help restore smooth rotation and consistent oil pressure. This is unused old stock, so cosmetic tarnishing or storage marks may be present, but performance is unaffected. A practical, authentic choice for keeping classic Villiers-built JAP engines running correctly.

Typical Applications:

Suitable for enthusiasts, professional rebuilders, estates, and museums maintaining original machinery.
