Description
Overview:
The Main Bearing (Flywheel Side) is a genuine Lister Petter component for Petters PJ Range diesel engines. It supports the crankshaft at the flywheel end, helping to maintain alignment, reduce friction, and protect the journal during operation. Supplied in size U/S 040, this means it is undersize 0.040 in (approx. 1.02 mm) and is intended for use with a crankshaft that has been ground to that undersize. Made from durable, engine-grade bearing materials and manufactured to OEM standards, it is suitable for professional rebuilds and careful DIY overhauls. This is unused old stock (vintage), so minor tarnishing or dust from storage may be present without affecting function. MPN: 265493. Suits Petters PJ engines and the wider PJ Range.

- Genuine Lister Petter part for assured fit and performance (MPN: 265493)
