Removing the
spindle 1Remove the two screws (1).
2Remove the straight pin (5).
3Remove the planetary gear (6) and the
ring gear (7).
4Remove the complete spindle sleeve (2)
from the cylinder.
1Removing the rear thrust bearing (7):
Lever off the special locking ring (8) with a
screwdriver and remove it (peel it off like a
key ring). The thrust bearing can be
removed in the following component
parts:
– washer
– thrust bearing
– two compensating washers
– profile ring with damper-O-ring
2Remove the retaining clip (6) and the
locking slide (5).
3Removing the spindle wheel (3):
Press the spindle wheel with a sleeve
against the disk springs (1) – the locking
ring (4) is released and can be removed

FDependingonthedate ofmanufacture
of the machine there are different ways to
remove the locking ring:
Date of manufacture up to 12/95:
Remove the locking ring (2) inside the
spindle (1) with aid of special pliers (3).
FThespecial pliers’(3)Id-no. dependon
the date of manufacturing of the tool:
- up to 05/94 = 4931 5990 58
- from 06/94 = 4931 5990 56
- from 08/94 = 4931 5990 56
Date of manufacture from 09/96:
To remove the locking ring use a special
tool (1) as shown in illustration.
1Turn the locking ring (2) with aid of the
special tool (1) such that one end of the
ringprojects theservice boring (3)approx.
2 mm.
2Insert a screwdriver into the service boring
(3) and lift the locking ring (2) from the
groove.Keep thescrewdriver inplace.
3Lever off the locking ring with aid of a
secondscrewdriver inserted into the other
serviceboring.Thelockingring comes free
from the inner grove of the spindle and can
be removed with aid of a hook.
