Description
Overview:
This Genuine M.A.G piston is a complete replacement assembly for the M.A.G 1029 SRL engine. With a 78.30 mm oversize (O/S) bore, it is designed for engines that have been professionally rebored to suit an oversize piston. The piston is manufactured from durable aluminium alloy for low mass and good heat dissipation, helping to maintain compression and reduce wear in demanding operating conditions. Supplied as unused old stock, it may show light tarnishing or storage marks but remains serviceable for refurbishment work. Identified by OEM No. 9020 324, it offers a precise, matched fit for the M.A.G 1029 SRL, restoring smooth running and reliable power delivery in vintage machinery used across construction, landscaping, and agricultural applications.
