12. Spokes
The spokes are of the single-butted type, 8-10
gauge, with 90° countersunk heads, thread
diameter .144 in., 40 threads per inch, thread form

All spokes initially have a bend of approximately
100°. After building the wheel, but before it is
finally trued, the spokes are straightened by hitting
them with a wooden or hide mallet thus giving
them a more acute angle of bend of about 80°.
13. Wheel Building and Truing
The spokes are laced one over two, and the
wheel rim must be built central in relation to the
faces of the nuts on the spindle. The rim should be
trued as accurately as possible, the maximum
permissible run-out both sideways and radially

being plus or minus /

14. Tyre
The standard tyre is Dunlop 3.25-17 in.
Ribbed. 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 tool-kit. 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.
15. Tyre Pressures
The recommended pressure for the front tyre
is 18 lb. per square inch.
16. Lubrication
Grease the bearings by packing them with
grease after dismantling the hub as described
above.
Note that the brake cam is drilled for a grease
passage but the end of this is stopped up with a
countersunk screw instead of being fitted with a
grease nipple. This is done to prevent excessive
greasing by over-enthusiastic owners. If the cam
is smeared with grease on assembly it should
require no further attention but in case of
necessity, it is possible to remove the screw, fit a
grease nipple in its place and grease the cam by
this means.
