Overview:
The Pair of Lister thrush/thrust washers is a genuine Lister Petter service part for the Lister HA diesel engine range. Supplied as a matched pair, these durable metal washers sit at the crankshaft end-float location to control axial movement and support smooth, reliable rotation under load. Their precision faces help protect mating components and maintain correct clearances, which is critical for oil film integrity and overall engine longevity. Typical uses include HA-powered equipment across plant and machinery such as pumps and generators. Dimensions (per washer) are approximately 111 mm (4 3/8") length, 55 mm (2 1/8") width, and 3 mm (1/8") thickness. This is genuine and unused vintage stock that may show light tarnishing from storage, with no effect on performance.
