you will need a knife edge bearing puller available from an auto parts shop or a good tool shop it will be a small puller that comes in to sections which are bolted together under the inner race of the bearing ( bit still in the shaft) and that section is attached to a bar with a screw through it that then pull the inner race off the shaft or if you are very careful , you can use a 4" angle grinder with a 1mm cutting blade and cut across the bit at an angle NOT IN LINE WITH THE SHAFT -as that will give the blade clearance to the windings -- so that the blade is clear of the windings cut down about 1/2 way then using a steel solid support under the bearing race , place a sharp cold chisel in the cut and using a ball pein hammer hit the chisel into the cut that will crack the rest of the race and you can then get it off with your fingers NOTE---IF YOU USE THE GRINDER AND YOU TOUCH THE WIRES WITH THE BLADE IT IS A NEW ARMATURE AS WELL AS BEARINGS SO BE VERY CAREFUL WITH THIS METHOD
