Description
Overview:
The Big End Shells (020) are precision bearing shells for the big end of the connecting rod on Petter industrial engines. They provide a smooth, low-friction surface between the con-rod and crankshaft journal, helping to maintain oil film and protect critical components. This Genuine Lister Petter part is intended for the Petter A-range, including Aa and Ab models, and is suitable for the Ac as well.

Manufactured from high-quality bearing-grade materials suited to pressurised lubrication, these shells support reliable, long-term service.
