Description
Overview:
The Main Bearing G/E Undersize 040 for Lister SR diesel engines is a genuine Lister Petter replacement bearing designed to restore correct crankshaft support and oil film clearance on engines that have had the main journals reground. It is a precision‐machined metal bearing shell made for durability and consistent performance in demanding industrial use. The undersize 0.040 in (1.02 mm) specification ensures a tight, accurate fit when the crankshaft has been machined to the matching undersize. Suitable for Lister Petter SR series engines, it helps reduce vibration, improve lubrication stability, and extend engine life. Supplied as vintage, unused stock, the bearing may show minor tarnish or storage marks that do not affect function. Genuine Lister Petter quality supports reliable, long‐term service.
