    First, if it is rust, try something more potent than WD40.  KROIL is
    available in the USA through mail order only, is one of the best
    penetrants I have ever found, works where nothing else will.  If you
    cannot see any set screws or such, I would think they are pressed
    on. Might suggest taking the shaft to a good machine shop and see
    what they think and maybe they could remove them with heat and or a
    press or cut them off.  I personally would not try to shim the
    bearings  to get them to "fit".  Try to get the correct bearing,
    especially if this is a high RPM shaft. 

    I have to say that I have not worked on this particular type of
    equipment, but if I were, the above would be my directions taken. 

Best of luck,
John Dach
