hey Tam, as long as the faces for the outside of the races are fine and the Left inside face for the bearing to sit flush against is ok then all is fine and dandy.

you must make sure that the left inside face is clean of dirt/grit before you install the bearing as the bearing sits flush up against the left hand inside hub.

the hub is conical inside and the left hand side is the wider end.

bearing installation:
put the left hand bearing in first and drive home till it wont go any further.
install spacer.
Right hand bearing goes in till inner race is just touching the spacer. do not use a socket to drive the right hand bearing in or you will set the bearings against the races and reduce the life of the bearings. if you are going to use a socket to put the right hand bearing in then be very very gentle when making final installation e.g. tap-check for clearance against spacer on inner race and repeat till it JUST touches the spacer then stop.
