Description
Overview:
The Main Bearing (Flywheel Side) U/S 020 is a genuine Lister Petter part for select Petter engines, including CC8/020 and CC8020. It is a precision shell bearing made from durable, steel-backed, anti-friction bearing alloy designed to support the crankshaft at the flywheel end. By maintaining the oil film between journal and bearing, it reduces friction and wear and helps the engine run smoothly and efficiently. The U/S 020 size denotes a 0.020 in undersize (approx. 0.51 mm), intended for use with a crankshaft that has been reground to that specification. Supplied as unused old stock, it may show minor tarnishing from age, but remains fully serviceable. Suitable for maintenance and restoration of classic Petter engines where correct clearances and reliability are essential.
Key Features:
- Genuine Lister Petter part for assured compatibility and fit on the flywheel side
- U/S 0.020 in (approx. 0.51 mm) to suit reground crankshaft journals to factory specification
- Steel-backed bearing with anti-friction lining for consistent oil film and low wear
- Helps stabilise the crankshaft, reducing vibration, friction, and heat
- Supports reliable oil pressure and improves overall engine efficiency and longevity
- Suitable for service, overhaul, and restoration of vintage Petter engines
- Unused old stock; appearance may include light tarnish without affecting performance
- Direct replacement design; check tang location and oil hole alignment during installation
Typical Applications:
Used during engine rebuilds and repairs on Petter stationary engines found in generators, water pumps, compressors, agricultural machinery, and site equipment. Ideal where the crankshaft has been reground by 0.020 in (0.51 mm) and correct main bearing clearances must be restored for dependable daily running and extended service life.
