Not having a suitable drift to hand I fitted the new bearings by stacking 8mm washers (and a big nut) and utilising an 8mm socket and bar and tapping the bearing down the shaft.
The longest part of this job was fitting the finished motor back nto the machine, dropping the screws inside the gubbins and trying to fish them out etc
! Anyway, job done, the motor on fast forward no longer sounds like a skateboard in a subway!
