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
trouble through grease finding its way past the
felt seals on to the brake linings) this greasing
point is of little value and the best way to grease
the bearings is 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.
