Driveshaft - Husqvarna K3600 Mk II Workshop Manual

DRIVESHAFT

Driveshaft bearing/shaft seal
If external leakage comes from the drive shaft, it is a sign that the shaft seal is
damaged. Worn roller bearings may be indirectly responsible for the leak.
Recommendation – replace bearing, shaft and seal
On machines that have many operational hours on the clock, the shaft seal
may cause damage to the surface of the driveshaft, reducing the integrity of
the seal. Play in the roller bearing causes major stress on the shaft slide bearing
that, when worn, makes it difficult to engage gears in the motor housing and
the cover, resulting in internal leakage and reduced motor power.
Therefore, it is recommended that the entire unit be replaced (as shown in
picture). This is available as a complete spare part.
