TO DISMANTLE FRONT WHEEL BEARINGS
Remove wheel from machine.
Remove nut securing brake cover plate, withdraw cover plate with brake shoes, etc.
Then remove brake cover positioning nut and washer.
Then turn to the right-hand side of wheel, remove adjusting ring lock nut and lift off
cover disc.
Then completely unscrew the adjusting ring.
Now carefully apply pressure to the threaded end of the wheel spindle which will eject
from the opposite end of the hub, the washer (7), oil seal (8) and oil seal cup (9) together
with the bearing outer ring (6). The wheel spindle with its two sets of rollers in cages
may now be lifted out leaving in situ only the fixed bearing ring together with the oil
seal, washer and cup for that side bearing.
If it is desired to remove these pressure is first applied to the visible washer, by which
the assembly is forced inward sufficiently to permit extraction of the retaining circlip,
after which through the medium of a mandrel or a piece of tubing of external diameter,
a trifle smaller than the hub bore, apply pressure to the inner edge of the fixed bearing
ring so that it is forced out of the hub end. As it emerges it will push out the end
washer (2), the oil seal (3) and the oil seal encircling collar (4) and the inner washer (5).
To refit reverse the above procedure remembering that after bearing ring (6), washer (5),
spacer (4), oil seal (3) and washer (2) have been inserted, to refit the circlip (I) snugly
in its groove and to then apply pressure to the inner edge of the bearing ring to force
the assembly tightly back against the retaining circlip.
finally, position the disc when tightening the adjusting ring lock nut so that access to the
grease nipple is possible.
