gearbox, distance collars, 41373 and 41372,
chain adjuster cams, the loose section of the
spindle and the spindle nut, 28832. The wheel is
then ready for reassembly into the machine.
14. Wheel Rim
The wheel rim is type WM2-17 in. plunged
and pierced with forty holes for spoke nipples.
The spoke holes are symmetrical, i.e. the rim can
be assembled to the hub either way round. The
rim diameter after building is 17.062 in., the
tolerances on the circumference of the rim
shoulders where the tyre fits being 53.642/53.582
in. The standard steel measuring tape for
checking rims is 5/16 in. wide, .011 in. thick, and
its length is 53.676/53.616 in.
15. 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
British Standard Cycle. The inner spokes are 5.5/8
in. long with an angle of bend 100°, and the outer
spokes 5.3/4 in. long with an angle of bend 80°.
16. Wheel Building and Truing
The spokes are laced one over two and the wheel
rim must be built central in relation to the outer
faces of the distance collars 41373 and 41372.
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.
17. Tyre
The standard tyre is Dunlop 3.25 – 17 in.
studded tread.
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 recommended pressures for the rear tyre
are 22 lb. per sq. in. for a solo rider. And 32 lb.
per sq. in. when a pillion passenger is carried.
19. 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.
