To Dismantle Rear Wheel Bearings; Front Brake Cover Plate - Matchless G3L Maintenance Manual

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and the speedometer gear box withdrawn.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seal cup (5), the oil seal (4) and the retaining washer (10) are then free to be withdrawn.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.
Reassembly is carried out in exactly reverse order, care being necessary after pressing
in the brake side bearing ring sufficiently far to permit fitting the circlip, to then force
the ring back until seal cup (5) is tightly in contact with the retaining circlip before
proceeding with further assembly.
Final adjustment of the bearings should allow the slightest possible degree of end play,
and when correctly adjusted just perceptible rim rock upon refitting the wheel should
be observable.
NOTE—Upon tightening the adjusting ring nut (13) the cover disc must be positioned
to permit application of the gun to the grease nipple, the hole in disc being provided
for that purpose.

FRONT BRAKE COVER PLATE

It is most important the front brake cover plate is correctly positioned.
It is retained to the front wheel spindle by an inside nut (part number 021931)
and an outside nut (part number 018071).
The inside nut must be positioned so that when the cover plate is applied, the outer
face of the latter lies flush with the hub shell edge.
The outside nut is fitted so that its hexagonal side is against the brake cover plate
