Description
Overview:
This circlip is a Genuine Lister Petter part for retaining the gudgeon pin inside the piston on Lister SL21 and other Lister two‐cylinder diesel engines. Made from hardened spring steel, it seats in the piston groove to stop the pin drifting, helping protect the cylinder bore and piston from damage. Supplied as unused old stock, it may show light tarnishing or storage marks, but performance is unaffected. It is suitable for routine service work or full rebuilds where secure gudgeon pin retention is critical to engine reliability. OEM No. 201 17470 ensures the correct specification and fit for the intended applications, giving confidence when maintaining engines used in pumps, generators, compressors, and other plant powered by Lister diesel units.
