4. Assembly
a) Slide the bearing inner races and bearing cages onto shaft (B11). Ensure that
the large outer diameter of the inner races are facing inwards on the shaft.
NOTE: ON ASSEMBLIES WITH TWO BEARINGS AT ONE END, THE ARRANGEMENT IS AS
FOLLOWS: INNER RACE, INNER SPACER, OUTER RACE, OUTER SPACER, INNER
RACE.
b) Press the bearing inner races onto the shaft so that they are tight against the
