Description
Overview:
This 40 mm Cylinder & Piston kit is a non-genuine replacement for Stihl MS230 and MS230 C petrol chainsaws. It replaces a worn or damaged top end to restore compression, starting and cutting performance. The cylinder is an aluminium casting with a durable NikasilTM-lined bore for wear resistance and efficient heat transfer, paired with a lightweight aluminium piston and steel piston rings. The kit includes the cylinder, piston, gudgeon pin, circlips and piston rings for a straightforward rebuild. The 40 mm bore (approx. 1.57 inches) matches the original specification, providing a direct fit on compatible models. Built to high standards, it offers a practical, cost-effective solution for routine maintenance or repair when the original cylinder has scored, seized or lost compression.
