Description
Overview:
The Main Bearing 020 Pair for Lister LD/SL Engine (part no. 201 12920/020) is a genuine Lister Petter component for crankshaft support in LD and SL series engines. Supplied as a matched pair of bearing shells for one main journal, it is designed to maintain the correct oil film, reduce friction, and keep crankshaft alignment accurate under load. The bearing is steel-backed with an anti-friction bearing layer for dependable service life in industrial and agricultural duty. Marked 020, it is typically intended for a 0.020 inch undersize crankshaft (about 0.51 mm), commonly used after a crank regrind. This is unused old stock and may show minor tarnishing from storage, which does not affect performance. Suitable for engine maintenance and rebuilds across fixed plant and mobile machinery driven by Lister engines.
