Description
Overview:
The Piston Assy 020 is a genuine Lister Petter piston assembly for the Lister SL diesel engine. It restores correct compression and oil control in worn or re-bored cylinders. Manufactured from durable, heat-resistant alloy with hardened mating components, it is built for long service in tough operating conditions. Supplied as a complete assembly with piston, rings, gudgeon pin and circlips, it is suitable for workshop rebuilds and in-field repairs on Lister SL engines used in construction, agriculture and industrial plant. Marked 0.020 in oversize (approx. +0.51 mm), it matches a cylinder finished to this oversize. This is New Old Stock (NOS): unused and fit-for-service, but may show light tarnish or storage marks. OEM reference: 570 10240 020.
