Description
Overview:
This Chain Brake Band is a genuine Husqvarna safety component for petrol chainsaws, engineered to stop the chain rapidly when the brake is engaged. Built from durable metal (steel band), it wraps the clutch drum and tightens under brake activation to prevent chain movement, helping reduce injury risk and machine damage. It is designed for Husqvarna homeowner and light professional saws, including the 136 and 137, and provides the correct fit and tension for consistent braking performance. Ideal as a direct replacement when the original band is worn, heat-scored, or broken, it restores the saw's safety function with dependable operation. Genuine status ensures compatibility with the brake mechanism and cover geometry. Manufacturer Part Number (MPN): 545137401.
