This Genuine Cylinder & Piston Assembly is an original Stihl replacement for the TS 400 cut-off saw (also listed as TS400). It replaces the top-end of the engine with a precision-machined 49 mm (1.93 inches) bore cylinder and matching piston to restore compression, power, and smooth running. Built from durable aluminium alloy with deep cooling fins, the assembly is designed to handle continuous site use and high temperatures. As an OEM component (Part No. 4223 020 1200), it matches factory specifications for fit and performance, helping to reduce vibration, improve starting, and maintain fuel efficiency. It is suitable for routine overhauls or when the original cylinder has worn, scored, or lost compression through heavy use.
