18. 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.
