Figure 23
1. Drum hub 4. Spacer 7. Ball bearing (2 each)
2. Spacer 5. Drum spindle
3. Lock nut 6. Seal (2 each)
Note: The seal side of each bearing (item 7 in Figure 23 ) should face inside
of the drum hub; refer to Figure 23 .
1. Use a press to install the bearings (7) and spacer (8) into the drum hub
(10). Pack the bearings with grease. Fill outside space of the bearing with
the grease.
2. Apply a coat of grease to the seals (6). Press the seals (6) into the drum hub
(1) with its flat side facing outside ( Figure 23 .
3. Apply grease to the shaft of the drum spindle (5). Carefully slide the drum
spindle into the drum hub bearings (7). Secure the drum spindle and drum
hub (1) with a spacer (2) and lock nut (3). Make sure that the drum spindle
(5) can move axially relative to the drum hub (1).
Note: The lock nut (3) turns hard on the drum spindle (5) when tightened.
Ensure that all rotation has stopped when tightening. A good solid sound
indicates the nut is full tight.
4. Install the drum hub plate (4) into the traction drum (1) and secure with
shoulder bolt (11).
Note: The fit between the drum hub plate (item 4 in Figure 22 ) and drum (1)
is a close tolerance and can be easily jammed. The hub can be rotated when
seated properly in the bore of the drum.
5. Secure the drum hub plate (4) to the drum hub (10) with the 4 bolts (2) and
washers (3). Tighten the bolts using an alternating pattern. Repeat tightening
sequence a second time.
