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.
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.
