Description
Overview:
This genuine Husqvarna piston stopper is a service tool designed to lock the piston in place during maintenance on compatible Husqvarna chainsaws. Made from a durable, high‐strength polymer with a robust form factor, it is engineered for repeat use in workshop and site conditions. The stopper threads into the spark plug hole to hold the piston securely, helping you remove or refit components such as the clutch, flywheel, and drive sprocket without damaging internal parts. It supports safe, controlled servicing and reduces the risk of crankshaft rotation while you work. Purpose-built for Husqvarna machines, it offers reliable fit and performance on models including the 136 and 141, matching the requirements of DIY users and professional technicians alike.
