Steering Head. To adjust the steering head ball
45
races, undo both clamp bolts at the fork crown and the
wedge
boit
at the steering head. Screw down the large
hexagon nut on top of the
"
Casquette
"
until play
in the bearings disappears but free movement
is
not
impaired. The special rubber rings above the upper
main tube covers will allow for variation in distance when
this adjustment
is
made. Secure the clamp bolts and
the wedge
boit.
Dismantling. With the wheel removed, take out the
screwed plug from the
"Casquette"
above the fork
legs.
The sliding member, together with the spring, may
then be withdrawn downwards. Tap the
boit
which
protrudes from below the sliding member until it is free,
bearing in mind that as the boit
is
tapped upwards, oil
will escape from the tube. The spring and spring tubes
are then free and may
be
screwed apart from each other.
Should it be necessary to remove the main tubes,
undo the clamp bolts at the fork crown and, with a special
key in the internai hexagon from above the
"Casquette,"
screw the tube free.
REAR
SUSPENSION
The bottom spring cups of the rear suspension units
are adjustable in three positions by means of a
" C
"
spanner. The bottom position
is
suitable for a
medium-
weight rider; the centre position for a heavy-weight rider,
or a medium-weight rider and a medium-weight passenger;
and the top position for a heavy-weight rider and
heavy-
weight passenger. The adjustment raises the rear end of
the machine to compensate for extra weight so that the
normal riding position
of
the suspension unit
is
always
roughly midway between the two extremes of travel.
Access to the interior of the spring boxes, for the
removal of springs, can be gained by removing the units
from the frame, pressing down the top cover and remov-
