Shopsmith Forums

I inherited my Mark V sn: SS1450440 from a dearly departed friend in 2003. I think I've used it more than he did for the 20 years he owned it. I like this old timer but the 1 1/8 hp motor failed. It won't even run on the test bench. The motor and sheaves turn & move freely, and have been cleaned & oiled.

I took the motor to the local electric rebuild facility here in GA and they told me this one is toast, to use their words. Time to replace.

I was on the parts site and found a PN: 513964 for this motor for 398 +. I'm thinking this unit, although 34 years old, is worth doing some upgrading.

Am I thinking correctly on the upgrading?

Thanks, KEn

You can find them used on eBay frequently.

There is also a fellow on eBay who rebuilds Shopsmith motors.

It may be toast to the local motor re-builder, and may not be for him.

If the windings are burned, that's a real issue. If not, it may be repairable.

Simon*e on eBay does it for 69.00 usually.

Thanks for the reply. The winding's are fried. Don't know why they fried, but I use to leave it plugged in all the time, and I suspect it was a lightening strike. My shop use to be in N. FL near the lightening test research center.

I think since my sheaves and everything else is in great shape, I'm going to bite the bullet and buy a new motor.


Folks have a great week and thanks again for the info. Ken

If you can afford it, think about getting a PowerPro headstock to replace it with. You can then always look for another used machine if you want a M5 around (having two machines IMO, is a real asset). If you can't justify a PP, then you can buy a very good machine complete sometimes for 3 or 4 hundred (the cost of fixing the one you have). Anyway, just thinking out loud ....

rjent, the price isn't the problem on getting a new headstock, room is my problem, I just don't have room for two machines. At my age I can't justify building an additional shop, even though that would be nice to have... I just regret that I can't take my tools with me when it's time to go.

Great day to all wood workers and carpenters, Ken

It might be prudent to replace the power switch and the power cord while you are replacing the motor as they are vintage parts that degrade.

There is a different wiring schema used in the newer motors that pigtails the white (neutral) leads together, and routes ONLY the black and blue (hot) wires to the switch.

When you get your motor, it will likely be the new wiring set-up. I have attached a file that will help visualize the connection types through the years as explained in one of the Sawdust Sessions.

Hope this helps answer any questions that might come up.
