Topic tags/keywords: ras repair sears electical motor question

I have a Sears Model 113.19771 radial arm saw I purchased in the early 80’s. It is in great condition and was my first major tool purchase. The motor is going out. It often will not turn the blade. I have replaced the capacitor in the motor but no other parts appear to be available from Sears. Anyone have a source for the small electrical motor repair of an item like this? I really hate to replace it.

Take the motor off and take it in to a motor shop. Some will charge
you for an estimate.

Either that or buy another saw. They sell for $50-100 on the secondhand
market in many places.

It may just be a dirty starter contacts. Sometimes you can blow compress air into the end of the motor where the contactor is located and clean it without disassembly.
This happened to my saw- about the same vintage. The motor would hum but the blade wouldn’t turn.

No one ever repairs anything any more. Everything is disposable and they just replace. You may be in luck that it’s from the ‘80s. Maybe look for a place that does small engine and generator repair.. Let us know if you have any luck, I have nearly the same saw and It’s been a long time since I tried to turn it on.

I solved my problem. A nearby seller on Craigslist had the same model of saw and motor as mine. I replaced the motor and some worn parts. It’s good for another 30 years…
