Description
Overview:
This Cylinder & Piston 52 mm set is a genuine Stihl replacement for restoring engine performance on the MS 461 chainsaw and GS 461 concrete cutter. The cylinder is a finned aluminium alloy barrel designed for efficient heat dissipation, paired with a precision‐matched piston to help recover compression, power and smooth running. It is built for demanding use in forestry, landscaping and construction settings. Supplied to Stihl specification under MPN 1128 020 1250, it is a direct-fit top-end component that helps extend service life when a worn, scored or seized cylinder assembly needs replacement. A correct 52 mm bore ensures proper sealing with a matched piston for reliable starting, consistent power output and reduced fuel waste when the engine is under load.
