RE-ASSEMBLY OF CUSH DRIVE
Fig. 2
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 ½ 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 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 are
brazed to the lockring 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 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 and unscrew the
bearing retaining ring 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,
speedometer drive gearbox, the spacing collar
and the felt washer. Remove the bearing
retaining circlip from the driving sprocket end of
the barrel. Between the two bearings is a spacer,
slotted at one end to enable a drift to be used on
the bearing at that end. Remove this bearing
first, then enter the loose section of the spindle
into the spacer and drive out the remaining
bearing by means of a hammer and drift applied
to the hexagon headed end of the spindle.
8. Hub Bearings
These are deep-groove Single-row journal
ball bearings. The sprocket/brake drum bearing
is a Skefko RLS7, 7/8 in. i/d, by 2 in. o/d, by
9/16 in. wide. Equivalent bearings of other
makes are Hoffmann LS9, Ransome & Marles
LJ 7/8 in., and Fischer LS9. The two bearings in
the hub barrel are Skefko RLS5, 5/8 in. i/d, by
1.9/16 in. o/d, by 7/16 in. wide. Equivalent
bearings of other makes are Hoffmann LS7,
Ransome & Marles LJ 5/8 in., and Fischer LS7.
9. Removal of Hub Driving Pins
To remove the six driving pins from the
aluminium full width hub, first remove the hub
cap after unscrewing the three screws attaching it
to the hub. Unscrew the six Simmonds nuts and
drive out the pins.
10.
Refitting Ball Bearings
To refit the sprocket/brake drum bearing, use
a hollow drift as shown in Fig. 3. The bearing is
first fitted to the fixed section of the spindle; the
spindle and bearing are then entered into the
sprocket/brake
drum
and
driven
home,
preferably under a press or using light hammer
blows.
The two bearings in the hub barrel are
pressed in, using the drift part of E.4823. First
