Description
Overview:
The Piston Ring Clamp/Piston Stop Kit is a genuine Husqvarna service tool set designed for accurate top‐end engine work on small petrol engines used in chainsaws, brushcutters, hedge trimmers, and power cutters. Built from durable metal components for repeated workshop use, it helps compress and secure piston rings while also locking the piston to prevent unwanted movement during disassembly or reassembly. Four ring clamp sizes cover common small‐engine bores: 50 mm (1.97 inches), 42 mm (1.65 inches), 35 mm (1.38 inches), and 30 mm (1.18 inches). The piston stop provides controlled piston stabilisation, reducing the risk of ring damage and improving the consistency of cylinder and flywheel work. Supplied as a Genuine Husqvarna part (502 50 70‐01), it supports reliable, precise maintenance for DIY and professional users.
