Belt pulley – bearing replacement
The clutch drum and belt pulley are joined units. The belt pulley has dual,
permanently lubricated ball bearings that face each other without spacers.
The outer rings of the ball bearings are fitted with a light force against the
belt pulley and a sliding fit against the crankshaft, which means that the belt
pulley can easily be pulled from the crankshaft when dismantling the clutch.
The special tool 504 56 79-01 must be used to replace the bearings.
Tools
The tool kit 504 56 79-01 is needed to replace the ball bearing of the clutch
drum. Use the tool to dismantle and fit the bearing as described below.
The tool kit consists of a support plate for the bearing (A), the sleeve (B)
and the cover (C). Note that the cover has different profiles, one side to
match the sleeve on dismantling and the other to match the clutch drum on
fitting. The kit also contains the screw (D) with washers and nut.
Grease the threads of the screw and the washers.

Dismantling
1. Fit the screw with the large washer on
the bearing.
2. Fit the socket and cover in position.
Fit a washer and nut.
3. It is a good idea to secure the Allen
key in a vice. Align the screw in relation
to the Allen key. Press out the bearing by
screwing it up in the socket.
Assembly
1. Secure the bearings' support plate in a
vice.
2. Insert both ball bearings.
3. Add the belt pulley.
4. Put the cover on and fit washers and
screw.
5. Press the bearing in by tightening the
screw until the bearing reaches the stop
in the belt pulley.

fit the washer on the crankshaft.
