Description
Overview:
This Genuine Husqvarna clutch spring (OEM 503 14 51 01) is a hard‐wearing replacement for the centrifugal clutch assemblies used on selected Husqvarna and Partner machines, including K950 and K1250 power cutters. Made from tempered spring steel with a durable black finish, it maintains the correct tension to engage and disengage the clutch reliably under load. Replacing a tired or broken spring helps restore smooth take‐up, reduces clutch slip, and protects the drum, shoes, and engine from unnecessary stress. It is intended for professional and DIY maintenance on compatible cut‐off saws, chainsaws, and pole/hedge trimmers listed below. For best results, match the OEM number to your machine before fitting.
