Rear Wheel (Detachable Type)

1. Description
This wheel is of the "detachable" type which
enables the main portion of the wheel to be removed
from the machine without disturbing the chain or
brake. The wheel incorporates the well known Enfield
cush drive and also a 7 in. internal expanding brake.
2. Removal and Replacement of Main Portion of
Wheel for Tyre Repairs, etc.
Place the machine on the centre stand, if necessary
putting packing pieces beneath the legs of the stand to
lift the wheel clear of the ground. Remove the dual
seat (if fitted) and the detachable portion of the rear
mudguard. Unscrew the three attachment bolts,
39316. Unscrew the loose section of the spindle,
39336, and withdraw this together with the chain
adjuster cam, 36649, preferably marking this to
ensure that it is replaced in the same position. Now
slide the distance collar, 39323, out of the fork end
and lift away the speedometer drive gearbox which
can be left attached to the driving cable. The spacing
collar, 39321, and the felt washer behind it may now
be removed to prevent risk of them falling out when

manipulating the tyre. If, however, these are too tight
a fit in the hub to come out easily they may be left in
place. The main body of the wheel can now be pulled
across to the right hand side of the machine, thus
disengaging it from the fixed section of the hub barrel
and the cush drive shell and enabling the wheel to be
lifted out of the machine.
When replacing the main portion of the wheel
reverse the foregoing procedure, locating the wheel
by the loose section of the spindle with the
speedometer drive gearbox and distance collar in
position before replacing the three attachment bolts,
39316. The cush drive shell can be prevented from
rotating when turning the wheel to line up the holes
for the attachment bolts if the machine is placed in
gear or the rear brake is operated. When replacing the
speedometer drive gearbox care must be taken to
ensure that the driving dogs inside the gearbox
engage with the slots in the end of the hub barrel.
Before tightening the centre spindle make sure that
the speedometer drive gearbox is correctly positioned
so that there is no sharp bend in the driving cable.
