6.13.7 Belt pulley bearings
The clutch drum and the belt pulley are connected units.
The belt pulley has 2 permanently lubricated ball
bearings that are adjacent to each other without
spacers. The outer rings of the ball bearings are
installed with a light force on the belt pulley. They are
installed with a sliding fit against the crankshaft. This
means that the belt pulley can easily be pulled from the
crankshaft when disassembling the clutch.
