A.J.S. 18S - Rear Brake Adjustment and Front Cover Plate

TO DISMANTLE REAR WHEEL BEARINGS
With wheel still in situ first of all slacken the nut (16), securing the speedometer drive
gear box. Then remove the wheel from cycle when the above nut should be removed
and the speedometer gear box withdrawn. (If wheel is of non-detachable type remove
the brake cover plate and withdraw the solid centre spindle together with all spacers
attached).
Next, slacken the adjuster sleeve lock nut (13) and completely unscrew the adjuster
sleeve (14) which will come away together with the sleeve upon which speedometer drive
is mounted and also the cover disc. Then withdraw the washer (3), the oil seal (4)
and the oil seal cup (5).
Now turn to the brake side of wheel and using a short bar of d" external diameter apply
pressure to the end of the projecting sleeve (6), which pressure will force out wheel
bearing ring (7) together with the two taper roller bearings (7) and the spacing sleeve
(8), leaving in situ only the bearing ring on the brake side together with oil seal, washers
and retaining circlip.
If it is desired to remove this bearing ring pressure must be applied to the washer
immediately under the circlip, until it is possible to extract the circlip. The outer
seal cup (5), the oil seal (4) and the retaining washer (10) are then free to be withdrawn.
The bearing ring may then be forced out of the end of the hub bore by applying pressure
to its inner edge, through the medium of a bar or tube of suitable diameter, passed through
the hub bore.
