my spinner is an old fella one speed.It just seized. the motor is still trying to turn so I took it out trying to get it fixed. tried generator shop, electrical place and no luck no one says they would work on it. In desperation I took it to my auto mechanic and he plugged it in and said the motor indeed was trying to turn the cup. He used a lube gun connected to air and lubed underneath the cup where there was little fitting where the oil gun connected. after lube he turned the wheel a bit and lubed again and it began to turn freely. I bring it home excited because my spinner been down for about a month. I resufaced my gravity shift and added a little polish to my v2 sanded. and it seized up again whats going on with my spinner? what should I do and who can do it. any and all info is greatly appreciated.

If its a tub mount, check for water seeping into the bearing. it could be flushing the grease out and allow the bearing to heat up causing it seize up.

should be able to take the bearing out and just replace it.

Remove the belt so you can determine for sure whether the problem is the motor or the cup shaft bearing. After removing the belt turn the motor on and see if the motor runs smooth. Turn the cup shaft by hand and see if it turns easy or hard. From the sound of things you probably need a new cup shaft bearing. If your not mechanically inclined you'll have to take it someplace to have it fixed.
