4. Removal of Brake Shoes for Replacement,
etc.
Remove the complete wheel as described
above, then remove the spindle nut, 28832,
chain adjuster and the distance collar, 41373,
thus permitting the complete brake cover plate
with operating cam, pivot pin, shoes and return
springs to be lifted off the hub spindle. The
brake shoes can then be removed after
detaching the return springs. The brake linings
are bonded to the shoes and if requiring to be
renewed, should be sent for servicing.
5. Removal of Brake Operating Cam and
Brake Shoe Pivot Pin
The pivot pin is threaded into the torque
plate, 41109, from which it can be unscrewed
after removing the locknut, 41375.
To remove the operating cam unscrew the
nut, 10314, which secures the operating lever to
the splines on the cam. A sharp tap on the end
of the cam spindle will now free the lever, after
which the cam can be withdrawn from its
housing.
6. Cush Drive
The sprocket/brake drum, 41233, is free to
rotate on the hub barrel. Three radial vanes are
formed on the back of the brake drum and three
similar vanes are formed on the cush drive
shell, 40967. Six rubber blocks are fitted
between the vanes on the brake drum and those
on the cush drive shell, thus permitting only a
small amount of angular movement of the
sprocket/brake drum relative to the hub barrel
and transmitting both driving and braking
torques and smoothing out harshness and
irregularity in the former.
If the cush drive rubbers become worn so that
the amount of free movement measured at the tyre
exceeds 1/2 in. to 1 in, the rubbers should be
replaced. To obtain access to them remove the
complete wheel as described above ; then unscrew
the loose section of the spindle, 41369,
completely. The main portion of the wheel can
then be lifted away from the assembly consisting
of the fixed portion of the spindle, sprocket/brake
drum complete with brake and the cush drive
shell. Now remove the brake cover plate complete
with brake shoes as described above, and unscrew
the three nuts at the back of the cush drive shell
after bending back the locking washers. The three
studs, 41002, are brazed to the lockring, 10097,
and should be driven out of the cush drive shell,
each a little at a time to avoid distorting the
lockring or bending the studs. The sprocket/brake
drum can now be separated from the cush drive
shell, and the six cush drive rubbers lifted out.
When reassembling the cush drive the entry of
the vanes between the rubbers will be facilitated if
the latter are fitted into the driving shell first and
then tilted. The rubbers should be liberally
smeared with soapsuds to facilitate entry of the
vanes. Grease the inner face of the lockring,
10097, before assembling and tighten the three
nuts down solid as there is a shoulder on the stud
which prevents tightening of the nuts from
locking the operation of the cush drive. Do not
forget to bend up the tabs of the three locking
washers.
When reassembling the cush drive, coat the
inside of the bore of the sprocket/brake drum
liberally with grease where it fits over the hub
barrel.
7. Removal of Ball Bearings
To remove the ball bearings take the complete
wheel out of the machine and separate the main
portion of the wheel from the sprocket/brake
drum, cush drive shell assembly, as described
above. To remove the bearing from the sprocket/
brake drum, first remove the brake cover plate
complete with brake shoe assembly ; then remove
the distance collar, 41105, and unscrew the
bearing retaining ring, 41108, with peg spanner.
Now screw the loose section of the spindle into
the fixed section and drive out the bearing by
hitting the hexagon-headed end of the loose
section of the spindle.
To remove the bearings from the loose half of
the hub barrel, first lift away the distance collar,
41372, speedometer drive gearbox, the spacing
collar, 40989, and the felt washer, 41006.
Remove the bearing retaining circlip from the
driving sprocket end of the barrel. Between the
two bearings is a spacer, 40995, slotted at one
end to enable a drift to be used on the bearing at
