20. 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.
