Page 92
DISASSEMBLY: (See figures 9.3.5 and 9.3.6.a)
- Slacken the wheel nuts.
- Lift the axle until the wheel is off the ground.
- Remove the wheel.
- Release the brakes (make sure that the vehicle cannot move).
- Remove the hubcap.
- Remove the split pin or pin from the spindle.
- Remove the castle nut.
- Remove the drum/hub assembly, using a hub puller if necessary: the outer ring, the grease retaining plates inside
the hub (depending on the model), the small bearing cone and cage come with the hub.
Check these parts: The bearing cups and grease retaining plates can be left inside the hub for cleaning.
- Remove the large bearing cage and cone from the spindle using a bearing puller if necessary.
- Check the oil seal between the spindle and the large bearing (or the wheel bearing seal depending on the model)
and replace these parts if necessary. A puller may be required to remove the wheel bearing seal.
Note the orientation of the oil seal for reassembly.
- Check the contact surfaces on the spindle for the bearing and seal and the threaded end of the spindle and remove
any bumps or asperities.
- Check the hub surfaces in the same way.
- Check the bearing face of the castle nut.
Clean and degrease all parts with a suitable cleaning fluid.
REASSEMBLY:
- Grease the spindle lightly.
- Refit the oil seal or wheel bearing seal (ensure that the seal is the right way around), a punch makes it easier to fit
the wheel bearing seal and avoids damaging the seal.
- Apply a generous coating of grease to the large bearing cage and the rollers, making sure that the grease
penetrates all around the rollers and under the cage.
- Fit at bottom the interior ring (cone) of the large bearing on the rocket, it is important to take care not to damage
the cage of the bearing, to go up the cone unit, rollers and cage (figure 9.3.6.a) on fixed to use if necessary tools as
shown in the figure 9.3.6.b, the effort to push must apply only to the cone, in no case on the cage or the rollers
what involves a deterioration of the bearing.
- Apply a 15 mm (5/8 inch) (small axles) or 20 mm (3/4 inch) (large axles) layer of grease all around and right across
the large and small bearing cups that are still in the hub.
- If the hub does not have grease retaining plates, put a large amount of grease in the centre of the hub to act as a
reservoir.
- Slide the hub/drum assembly over the spindle and the brake shoes keeping the hub perfectly straight and aligned
until it is in contact with the oil seal at the back of the spindle.
- Apply a generous layer of grease to the small bearing cage and rollers and fit the assembly to the spindle.
- Fit the castle nut and adjust it as described above (See section 6.4.3.5 ADJUSTING THE WHEEL BEARINGS).
- Lock the castle nut with a hair-pin clip or new split cotter pin as appropriate.
- For hubs without grease retaining plates, fill the hubcap with grease.
- Refit the hubcap.
