Topic tags/keywords: craftsman 10 table saw model number 11327520 table saw motor question

Hi,

New to your group and bringing a problem in hopes of getting some good advice.

I have a Craftsman 10” Table Saw Model 113.27520 that has been in my family for something like 70 years. It’s been a great workhorse and I am totally dependent on it.

Today, the motor suddenly stopped working. I had used it minutes before to square the end of a board. I turned it off and when I turned it back on, it simply “buzzed” – the motor did not turn. I’ve tried a lot of different things with no improvement. Since it does have a capacitor to aid in starting, I think it might be that but I am not an electrician.

I’ve since been looking around for a replacement motor with no success (at least with something identified as being the right motor for this saw).

Has anyone gone through this – and do you have any suggestions as to what may be wrong or did you find a good replacement for the motor?

Some details of the current motor from the label:

Craftsman Motor: 1 Horsepower Capicitor Motor Ball Bearing 3450 RPM 115/230 Volts (using as 115) 60 cycle 11.4 / 5.7 Amps 1 Phase 40 degree C Temp. Rise Frame KS 73 BX BN Style 237 Mod No. 113.1936.3 10225

Thanks.

Jim

Typical behavior for a failed start circuit – either the centrifugal switch or capacitor. Capacitor is easy to test using a simple multi-meter in its highest ohms setting. 9 out of 10 times, the capacitor is the culprit as they do not last forever. If the cap tests ok, then you need to check the centrifugal switch, which usually requires you having to open up the motor, or at least remove one of the end bells.

No need to pay out the nose for a simple fix unless you just want a new motor – which will then bring in a whole ‘nother set of issues you will have to address (frame size, direction, speed, etc…).

Been where you are.
For me it was as simple and cleaning out the ends of the motor with an air hose. The centrifical switch was full of dust and dirt.

Many thanks to all who replied. I am back in business with the saw. Seems to have been a sawdust buildup.

Some notes for folks who may come after with a similar problem:

Most of the sawdust was in the base of the motor – which is where the capacitor lives. I had to dismount the motor from the saw. Cleaned out the sawdust I could see, vacuumed as well as I could, and plugged it in. The motor started up (probably better than it has in 20 years – which is about when I moved it to my shop from my father’s) and still runs true. With no load on the motor (not connected to the saw), the stopping time runs for minutes.

Remounting was not particularly fun – the two lower bolts have very little clearance for the washers and nuts. Having a second pair of hands to hold the motor seems necessary because of the weight and lack of any handles on the motor. A little work getting the alignment right and the saw was good to go.

Have your say...
