rear hub bearing fitting

hi everyone
just begun rebuilding series 3 125 engine. i have drifted in the rear hub bearing (out of the freezer) after warming the casing and waiting for the change of tone when it was fully home. is it supposed to sit flush with the casing on the outside? mine is slightly proud (about 1mm) and i am concerned about tightening up the plate.
thanks in anticipation
