ADJUSTING THE BEARING
CLEARANCE
1. Open the upper chamber.
2. Remove the fastening bolts (M10) (7) and the
upper bearing housings (6).
3. Remove the grease from the bearing housing.
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 spacer ring (3) if the bearing is at the
feeder side.
7. Measure the radial clearance on top of the bearing
between the rollers and outer ring with a feeler gau-
ge. The clearance should be 0.02–0.03 mm (0,008-
0,012”). Measure the clearance by pushing the feeler
gauge between the rollers (point A, Fig. 8b.) through
the bearing and then moving the gauge back and
forth between the rollers and outer ring - see Fig. 8c.
Do not force the feeler gauge through the clearance.
8. If the clearance exceeds 0.03 mm, bend the clawof
the securing ring (2) out from the notch on the axle
nut (1).
9. The bearing is tightened by turning the axle nut
clockwise with a 70 mm (2 3/4”) hook spanner un-
til the right clearance is achieved. Do not tighten by
hammering the axle nut.
10. Turn the axle nut clockwise until the notch is
aligned with the nearest claw of the securing ring.
Bend the claw into the notch. Do not bend the claw
that was bent earlier.
11. Lower the disk to the bearing housing.
12. Install the upper bearing housing and tighten the
bolts (6) to 50 Nm (36 7/8 lbf).
13. Lubricate the bearing housing. An excessive
1amount of grease causes overheating and impairs
lubrication.
