Re: (ET) Pulling the motor bearings



Actually I did use a split puller.  Maybe my armature windings were unusually close to the bearing.  Apparently something cocked while pulling and the edge of the puller severed a wire.  Probably easy to avoid if you check the back side of the puller as everything tightens up.

Bill and others,

When pulling bearings off a motor do yourself a favor.  Use a split bearing puller.  (Google split bearing puller ot split bearing attachment to see what they look like.)  Standard wheel pullers are too big and can damage windings or commutators.  (Evidently Chris ran into this issue.)  You can get away with wheel pullers sometimes, but the split bearing pullers were designed specifically to remove ball bearings in tight quarters.
