REPLACING THE BEARING
Open the upper chamber. See Section
Opening and removing the upper chamber.
Remove the fastening bolts M10 (7) and
the upper bearing housings (6).
Mark the location of the tightening cone on
the shaft.
Lift the disk.
Bend the claw of the securing ring (3) out from
the notch on the axle nut and open the axle
nut.
Remove the axle nut, securing ring, spacer
ring (4), bearing (5), spacer ring (9), and
tightening cone (10).
Install the tightening cone, spacer ring (9), and
bearing on the disk shaft. Note the thickness
of the spacer ring (9) - see Fig. 28.
Install the securing ring with the claws facing
outwards and the inside claw in the groove of
the tightening cone, and install the axle nut.
The inner ring of the bearing should press
tightly against the tightening cone.
Tighten the axle nut with a hook spanner until
the bearing is tightly on the cone, or to 80 Nm.
However, the outer ring of the bearing should
turn freely. Note the location of the tightening
cone on the shaft.
Bend one claw of the securing ring (3) into a
notch on the axle nut.
Install the other half of the dust cover and end
plate on the bearing housing. Install the spacer
ring (4) on the shaft.
Lower the disk to the bearing housing.
Attach the other half of the dust cover to the
upper bearing housing; install the upper
bearing housing fastening bolts and tighten
to 50 Nm.
Lubricate the bearing housing. An excessive
amount of grease causes overheating and
impairs lubrication.

The bearings at the feeder side and splined shaft
side are different from each other. The bearing
at the splined shaft side, Fig. 29., does not have
spacer rings (4 and 9) and an end plate (1). The
bearing at the splined shaft side has dust covers
on both sides (11).
