washer 'B ' which will be seen under the spindle nut ` C' and unscrew the nut in a normal anti-clockwise
direction. Take off the tab washer and draw the brake drum complete with bearings off the spindle.
Examination of the drum will show that there is a large bearing ` D' on the inner end of the shell
adjacent to an oil seal ` E' which has the lip facing towards the bearing. On the outer end of the shell is a
smaller bearing' F ' and there is a distance piece ` G' between these two bearings.
Remove the brake shoes by prizing them from the brake cam and the fulcrum pin, noting that the shoes are
fitted with the narrow side towards the brake back plate and that there is a distance piece ` H ' o n t h e cam
spindle between the shoes and the back plate.
To release the lower member from the fork, unscrew the two domed nuts' E'(Fig. 29) at the lower end of
the member. The front nut is removed with a spanner using a screwdriver to hold the slotted end of the
damper rod. In the case of the rear or fork spring nut, no screwdriver will be necessary.
With the two domed nuts removed the lower member can be drawn off the two fork tubes. The two
shouldered washers ' F', one on the spring stud and the other on the damper rod, may come away with the
lower member, but in any case they should be removed and kept until ready for re-assembly. The spring can be
removed by unscrewing the bolt and washer at the upper or crown end of the fork; this will release the spring
complete with the bottom and the top scrolls.
To take out the damper, unscrew the disc valve `G' in the end of the tube and draw the damper out
complete with washer and nut at the top.
The dust cover can be removed by taking out the centre bolt and elongated plate which locates
between the two fork tubes on the fork crown.
The brake cam lever can be released by unscrewing
the nut on the lever and the cam can then be drawn
through the lower member. The fulcrum pin is a press
fit in the lower member and should not be removed.
If the hub spindle is to be removed it will be
necessary to flatten the tab washer on the outer end
of the spindle, unscrew the nut and then heat the
aluminium sliding member in hot water before
tapping the spindle through towards the brake drum
side. Note that it is located by two flats.
Hub Bearings
The larger of the two bearings is fitted from
inside the drum with the oil seal between the bearing
and the brake shoes, the lip of the seal being towards
the bearing. The smaller bearing is fitted from the
outer end of the hub shell (i.e., the locknut end) with
the distance piece between the two bearings.
Head Bearings
The bottom steering head cone is a press fit on to the
fork steering column and the bottom cup is a press
fit on to the outside of the steering head tube, the top
cup being a press fit into the tube. There are 28 steel
balls in each head race. A broad rubber band is
employed on the lower race as a dust excluder.
When the head races are to be renewed (this is
possible without removing the head tube or legshield
from the frame), the bottom cup should be removed
