REPLACING THE BEARING
1. Open the upper chamber.
2. Remove the fastening bolts M10 (7) and the upper
bearing housings (6).
3. Mark the location of the tightening cone on the
shaft.
4. Lift the disk.
5. Bend the claw of the securing ring (3) out from the
notch on the axle nut and open the axle nut.
6. Remove the axle nut, securing ring, spacer ring (4),
bearing (5), spacer ring (9), and tightening cone
(10).
7. Install the tightening cone, spacer ring (9), and
bearing on the disk shaft. Note the thickness of the
spacer ring (9) - see Fig. 7a.
8. Install the securing ring with the claws facing out-
wards and the inside claw in the groove of the tighte-
ning cone, and install the axle nut.
9. The inner ring of the bearing should press tightly
against the tightening cone.
10. 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.
11. Bend one claw of the securing ring (3) into a
notch on the axle nut.
12. Install the other half of the dust cover and end plate
on the bearing housing. Install the spacer ring (4)
on the shaft.
13. Lower the disk to the bearing housing.
14. 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.
15. Lubricate the bearing housing. An excessive
amount of grease causes overheating and impairs lub-
rication.
The bearings at the feeder side and splined shaft
side are different from each other. The bearing at the
splined shaft side, Fig. 7b., 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).
