Description
Overview:
The Piston Assembly 38mm is a non-genuine replacement part for Stihl 018 and MS 180 chainsaws, designed to restore compression and smooth running in small 2‐stroke engines. Built for reliability, the piston is typically made from lightweight aluminium alloy for efficient heat transfer, with a hardened steel wrist pin for strength. It is sized for a 38 mm bore (1.5 inches), matching the original top end on these models. Use it to replace a worn or damaged piston to regain power, reduce blow‐by, and support easier starting. Dimensions include a pin length of 24 mm (0.94 inches) and a crown-to-centre distance of 13 mm (0.51 inches). Replaces OEM references 1130 030 2004/11300302004. Supplier MPN: 350 029.
