Repair a bench grinder help needed

[jeffberk]

I have a Craftsman 319.211260 6-inch bench grinder. While buffing out a part, the part slipped and jammed the right side wheel. It stopped spinning but the left wheel kept spinning. Did I shear the rotor shaft? Is this worth repairing?
Thanks
Jeff

Never mind...
I just realized that the sudden stop caused the left side grinding wheel to come loose so it was spinning.

I was gonna say, your grinder would have to have a pretty serious motor (and an extremely heavy wheel) on the other side to shear the shaft.
