Wheel Bearings Lightweight
Front wheel (1959 Model). Remove the brake cover plate assembled,
then knock out the wheel spindle which will eject the bearing, the oil
seal and cup.
Front wheel (1960-62 Models). (Fig. 30). It will be seen that the outside
diameter of the spacing tube (13) is nearly the same as the inner member
of the bearing (12). In consequence the projection into the spacing tube
is small.
Use a steel rod with a square end, inserted through the inner member
of nearest bearing and 'feel' for the projection. One or two blows on the
rod with a light hammer will dislodge the bearing and bring with it the
oil seal and cup.
Rear wheel (all Models). Use the method detailed for the 1959 front

Front wheel bearings. These are journal type and no adjustment is neces-

Bearings should be cleaned and re-greased at five to eight thousand
miles.
Bearing assembly. The assembly sequence is in the following order:
Oil seal cap.
Oil seal felt washer.
Oil seal collar.
Oil seal thin washer.
Bearing SKF 6302 (02).
A spacing tube separates the two bearings, both assemblies are identical.
Removing front wheel bearings. Use a steel rod or bar with a section of ¼".
Insert this tool half-way inside the hub and lever it sideways, which
will move the bearing spacer tube.
Place the tool on the bearing ring and drift out, moving the tool from
one side of the bearing ring to the other.
Brakes (Lightweight Models). The front and rear brake shoes are identi-

When new linings are required and when possible, service exchange
brake shoes should be used.
