To remove the brake drum. With the rear wheel removed: Take off the
brake rod hand adjuster, then remove the rear chain connecting link.
Release the nuts securing the dummy spindle, pull back the brake drum
clear of the fork ends.
To dismantle front hub. The wheel hubs are packed with grease during
initial assembly, and should not need further lubrication for at least
10,000 miles, when the hubs should be dismantled for cleaning and fresh
grease used. To dismantle the front hub, with the wheel removed take
away the brake plate with brake shoes.
Unscrew bearing lock plate on left side of hub, holes are provided for
a peg spanner or use a punch. If the plate resists removal use a little heat
which will facilitate removal, take out felt sealing washer and distance
piece.
To eject the bearings use a drift through the brake side (the front wheel
spindle can be used for this purpose) when a few light blows from a
mallet will drive out the bearing until it is clear of the hub, and no more,
as the other bearing goes into the hub during this process.
Take out the spindle, or drift, invert the wheel and repeat the process
to eject the double bearing which will bring with it the large steel washer.
the felt washer, also the thin steel washer.
Assembling the hub. Clean and repack both bearings with fresh grease
(see table of lubricants). Press into the left side of the hub the single
bearing, fit the distance washer (flat side against the bearing), then the felt
washer and secure with the lock plate.
Invert the hub, insert the distance tube (small end first) against the
bearing.
Enter the double bearing square with the hub, use a drift through both
bearings and drive home until the bearing abuts against the distance tube.
Fit the smallest of the two washers, the felt washer, then the large steel
washer.
With a suitable punch peen the hub material, where it joins the washer
in three equi-distant positions to retain the washer.
Rear hub dismantling. With the wheel removed, remove the speedometer
drive lock ring (this has a lefthand thread), take out felt washer and dis-
tance piece. To eject the bearing use the wheel spindle with its washer
also the distance piece that goes between the speedometer drive and the
frame placed on the spindle. Partially drive out the bearing until it abuts
against the reduced diameter inside the hub. Take out the spindle, use
a short length of steel tubing with the outside diameter slightly smaller
than the inside diameter of the bearing and drive out the bearing.
Invert the wheel, then drift out the other bearing, which will take with
it the steel cup, felt washer and the thin steel washer.
Assembling the hub. Deal with the bearings as already described and
assemble by first fitting the single row bearing, in the reverse order des-
cribed for dismantling, with the following precautions: when tightening
the lefthand lock ring avoid damage to the slots for the speedometer
drive. Finally "peen" the hub dished washer to the hub. The hub assembly
sequence is shown in Fig. 29.
Dismantling the brake drum. A bearing is not used in the brake drum:
