Bearing replacement – needle bearing
For a long time, a clutch drum with needle bearing has been the standard
design on Husqvarna petrol-driven power cutters. The needle bearing is
lubricated via a channel in the crankshaft from the crankcase.
In 2007 the needle bearing is being replaced with a ball bearing. Please note
that machines with a needle bearing cannot be fitted with a ball bearing as the
crankshaft and clutch drum are of different dimensions.
