Removing Blades with Bearings

Combi 122
You can recognise this unit by the fact that
the collar on the bearing housing is located
on the underside of the unit's cover.
1. Remove the cutting unit's upper cover,
see Belt Replacement on the Combi 122
Cutting Unit on page 67.
2. Loosen the spring that tensions the V-
belt (1) and pull the belt off.
3. Loosen the screw that holds the belt
pulley (2) a few turns. Lock the blade
with a wooden block or hold the belt
pulley in place, with an oil filter wrench,
for example.
4. Remove the nuts, which hold the bearing
housing in position, from the top of the
cover. Make sure that the unit is
positioned with the belt pulley against
the unit's cover.
5. Place a wooden block under the unit
cover so that the blade is free from the
supporting surface. Knock on the screws
to remove the belt pulley. Do not knock
hard enough to deform the cover. If the
belt pulley is stuck, heat it with a hot air
gun. Try not to use a puller as it can
deform the belt pulley. Do not lose the
key that sits between the pulley and the
shaft.
