6.4.3.7 REPLACING THE WHEEL BEARING
New grease retaining plates should be fitted to hubs with grease retaining plates (See figure 9.3.5), as the plates will
be damaged while removing the bearing cups.
Unpack the bearings at the last moment and never mix them up.
To replace the wheel bearings, follow the instructions for removing the hub (see section 6.4.3.6 LUBRICATING THE
WHEEL BEARINGS) and remove the bearing cups from the hub as follows.
REMOVING THE BEARING CUPS FROM THE HUB
Note the orientation of the bearing cups and grease retaining plates for reassembly.
- The bearing cups are an interference fit and must be punched out using a hammer and a mild steel punch (See
figure 9.3.7.a).
- If the hub has grease retaining plates, these will be punched out at the same time as the bearing cups and will,
therefore, be damaged.
FITTING NEW BEARING CUPS INTO THE HUB:
Make sure that the bearing cups and grease retaining plates are the right way around.
NB: Never fit the bearing cup with the bearing cone and rollers in place
- If the hub has grease retaining plates, first put the grease retaining plate in its seating (the right way around) and
ensure that it remains well centred and in place while the bearing cup is being fitted. Re-check when the operation
is complete.
- Fit the bearing cups and punch into place using a mild steel punch as shown in figure 9.3.7.b.
Take care that the bearing cups are straight and that they are firmly against the seating in the hub.
