Motor Rebuild?

Post by bfoss »

Looking for some detailed help here. I was ripping a 4X4 and my Mark V (serial number 146700) got slower and slower then popped the circuit breaker. Of course I reset the circuit and tried again. It got worse, then I noticed the smoke :(
I took apart the headstock and unmounted the motor. Sitting on the bench I plugged the motor in, flipped the switch and got a hum and a spark. :eek:
Other than that everything looks OK.
So, am I "fried" or is it possible to do repairs on the motor myself. I'm currently un-employed and can't spend the $400+ for a new motor.
I followed the videos on disassembling the headstock and was hoping for similar references on the motor.
Thanks for all the great help and advice on the forum!

Shopsmith does not have repair information on the motor. I'll suggest taking it to a motor repair shop for a "diagnosis". If the repair is too expensive, such as a rewind, look on eBay. Used motors usually go for 1/4 or less than the cost of a new motor.

I have had great success rebuilding/repairing "non-operating" Shopsmith motors. If your motor has a burnt smell, then replacing it may be the only solution. I have not found any factory information for any Shopsmith motor.

I have been able to accumulate a lot of information and pictures from experience and doing different modifications to the motors. Contact me off-line with all the motor information and any pictures you may have of the motor. I can offer my opinion/information as to what I believe is possible with your motor. I can help you in disassembling and testing your motor once I know what motor you have.

If the motor is an 'Emerson' and it IS fried, please contact me prior to 'discarding it'. I be needing an 'internal' part. TIA
