Description
Overview:
This Genuine Husqvarna Clutch Assembly is a centrifugal drive unit for petrol saws, built to restore smooth power transfer from the engine to the chain.

A precision 7.4 mm hole size ensures a consistent fit with the correct crankshaft interface. Supplied as a direct replacement, it helps maintain correct chain speed under load, protects the engine from stalling during snags, and extends the service life of surrounding drive components when fitted and maintained correctly.
