with the brake shoes resting on the top of the
blocks. Using a tube or drift of suitable
diameter, tap the drive flange out of the hub. It
is likely that the inner race of the outer bearing
together with the oil seal and the outer
bearing distance piece will come away with
the flange (see illustration). If this happens,
carefully remove these items from the flange
with the aid of a puller.
4 Undo and remove the four bolts securing the
brake backplate to the swivel hub and lift off
the backplate with brake shoes still in position.
5 Clean away any surplus grease from the
centre of the hub between the bearings, and
then prise out the two oil seals using a
screwdriver. Note that there is a spacer fitted
between the rear oil seal and the bearing
outer race.
6 Using a tube or drift of suitable diameter
tap out the bearing inner races away from the
centre of the hub. Take care not to lose the
balls which will be dislodged as the inner
races are released, and recover the spacer (if
fitted) between the two bearings.
7 Firmly support the swivel hub in a vice and
drift out the two bearing outer races from
each side of the hub.
8 Clean the bearings and swivel hub
thoroughly using paraffin or a suitable solvent
and dry with a lint-free rag. Remove any burrs
or score marks from the hub bore with a fine
file or scraper.
9 Examine carefully the bearing inner and
outer races, the balls and ball cage for pitting,
scoring or cracks, and if at all suspect renew
the bearings. It will also be necessary to
renew the oil seals as they will have been
damaged during removal.
10 If the old bearings are in a satisfactory
condition and are to be re-used, reassemble the
balls to the ball cage, place it in the outer race
and then press the inner race into position.
