Description
Overview:
The Piston Assembly R1 (88.30 mm) for the M.A.G 1045 SRL engine is a genuine replacement part designed to restore correct compression and smooth running in demanding construction and garden machinery. Supplied to OEM specification under M.A.G reference 9020 157, it is intended for 1045 SRL engines up to X 144 (except X 100). The piston body is typically manufactured from a high-grade aluminium alloy for low mass and good heat transfer, with matched components to maintain correct clearances and sealing within the 88.30 mm bore. This assembly helps reduce blow-by, stabilise idle, and support reliable starting. Supplied as unused old stock, it may show light tarnish or dust from storage, but remains serviceable, making it suitable for routine maintenance or sympathetic restoration work.
