between the fork ends. The rim should be trued
as accurately as possible, the maximum
permissible run-out both sideways and radially
being plus or minus 1/32 in.
Fig. 5 shows the difference between the
lacing when using Dunlop and Palmer rims. The
key to correct lacing is the inside spokes to the
large flange on the cush drive shell which must
slope in the direction shown in Fig. 5. With the
Dunlop rim this spoke goes to the middle hole
of one of the groups of three (see paragraph 14)
and the rim must be built into the wheel so that
these groups of three holes are on the right of
the centre line when the cush drive is on the left,
i.e. the inside spokes to the large flange cross
from the left to the right of the centre line.
With the Palmer rim the spokes from the
large flange on the cush drive shell go to the
more steeply angled holes in the rim which must
be on the left of the centre line when the cush
drive is on the left, i.e. none of the spokes
crosses from left to right of the centre line.
17. Tyres
Standard tyres are Dunlop 3.50-19 in.
Universal tread except on the "350 Bullet" where
a 3.25-19 in. Universal tyre is used.
When removing the tyre always start close to
the valve and see that the edge of the cover at the
other side of the wheel is pushed down into the
well in the rim.
When replacing the tyre fit the part by the
valve last, also with the edge of the cover at the
other side of the wheel pushed down into the
well.
If the correct method of fitting and removal
of the tyre is adopted it will be found that the
covers can be manipulated quite easily with the
small levers supplied in the toolkit. The use of
long levers and/or excessive force is liable to
damage the walls of the tyre. After inflation
make sure that the tyre is fitting evenly all the
way round the rim. A line moulded on the wall
of the tyre indicates whether or not the tyre is
correctly fitted. If the tyre has a white mark,
indicating a balance point, this should be fitted
near the valve.
18. Tyre Pressures
The load which the tyre will carry at
different inflation pressures is shown below:
19 . Lubrication
A greasing point is provided in the centre of
the hub barrel. Unless the barrel is packed full
with grease on assembly (which is apt to lead to
