Topic tags/keywords: sears motors repair grizzly

Tonight I turned on my table saw, and the motor just hummed. I removed the belt, and it still just hummed. I took it out of the brackets, and blew it out with compressed air, and it just hummed (and smoked a little).

It is a 1 hp Sears motor and is about 30 years old. Should I take it down to the motor repair shop or just get ready to order a new one?

Could it be that the capacitor went bad?

Any helpful suggestions would be greatly appreciated.

Did you try rotating it by hand. Also as it was trying to start?

Karson,

Yes, I tried to spin it to see if this would get her going – it didn’t.

Could be a capacitor. But the smoke sounds like a bigger problem. Does this Sears motor look like it would have a local replacement or does it require a Sears replacement.

It looks like (to me…) it could have a local replacement. I don’t have any idea what a 1 hp motor replacement would cost; do you?

Less than $100.00 (Maybe)

If it has a frame number on the label then any motor with the same frame number is a direct replacement.

A 30 yr old motor might not have a frame number. Google for frame numbers and you should find a chart that has the specs for frame numbers. Shaft diam. height from base, hole spacing in base etc. You might be able to fit your motor into the correct frame catagory and then just purchase one of them.

I had to purchase a motor for a drill press that was Tiawan for the toy workshop and I matched the specs up and bought a replacement. The motor repair place wanted over 300.00 for their motor. I bought one for $125.00

Depending on the saw you might want to increase the HP for a little more power.

That’s what I’m afraid of, Karson, that the local motor repair place is going to charge a lot. If I can work around them somehow, I can probably do a lot better like you did.

I will look for that frame number. Did you buy yours online somewhere?

I bought it at Tractor Supply. A farm supply house. I walked in and bought it.

Wow! I hope I’m that fortunate. I tried looking for a replacement motor at Sears Parts.com, but it didn’t list a motor, just replacement parts for the motor.

I was just getting ready to finish the construction of my “resaw jig,” and my saw quit. I had used it several times this evening.

Tom here is a frame chart

48 and 56 are a kind of standard frame number

Good luck.

Karson,

I looked on my motor and it was a G56Z frame number. Is that a standard one?

Tom here is a Bob Via page about your saw. I didn’t read it all.

The 56 Z might have a longer shaft than the standard z motor frame. I couldn’t find anything in g yet.
