Description
Overview:
This genuine Husqvarna piston stop is a service tool for locking the piston via the spark plug hole while working on the engine. Made from durable black plastic, it is designed to hold the piston securely so you can safely remove or refit components that are torqued to the crankshaft. It is intended for Husqvarna professional chainsaws including the 550XP and 560XP, and also fits the T540XP. By preventing piston and crank rotation during maintenance, it helps protect internal parts and supports accurate, controlled work. Supplied under MPN 575293601 (also known as 575 29 36-01), this OEM tool offers the correct fit and function for the listed models, and suits both workshop and site use by technicians and competent DIY users.
