Re: Bench Grinder Motor Troubleshooting

If you could hand spin it, then it probably wasn't the bearings. More likely it was the start up gizmo. Some use a capacitor, others have a centrifugal operated switch that runs a 2nd coil to start the thing spinning. Bad switch = no spin. Could be what the worn thing did.
