17. Tyre
The standard tyre is Dunlop 3.50-19 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 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.
18. Tyre Pressures
The recommended pressures for the rear tyre
are 20 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.
