Does anyone out there know how to get the main motor shaft bearing out of the GMC 12" slide compound mitre saw? Mine has failed (the noise is atrocious), but nothing I have tried will get the bearing out. I have worked from both the blade side and from the motor casing side, but am reluctant to use more force to get the bits apart than I already have, in case they are bolted together somehow that I have yet to discover.

Any ideas would be appreciated.
