Motor control box Sears Tablesaw


I have a Delima.
My brother had a Sears 9" Tablesaw Model #113.242700. It quit him, shorted switch. He disassembled the motor control box and forgot how it all went back together so he gave it to me. Would like to reassemble the box but all sears owners manual drawings convieniantly fail to show where all the wires hook up. Could anybody help with info on how to hook up all the components. Thanks alot

Hi, I believe I have that exact tablesaw. I found it alongside the road with a free sign on it.

Does it have the switch mounted in the front?
Is it direct drive?

If so, I can probably help you out. I suppose you want me to take mine apart and draw you a diagram, huh. Might take me a few days.

Does this saw only have a start and stop switch or button? I see the capacitor in stubbies very clear post is in the control box.

Go to the motor and see if you can get some info from the name plate. If we know what type of motor, how many leads and what colors, I can tell you how to start and stop the motor.
But I am sorry to say that Sears does not provide much useful information on any of their proprietary equipment.
Check the motor nameplate anyway. Maybe this saw old enough that they were actually using NEMA nameplates.
You might even find a drawing on it, but I doubt you will.

Unfortunately, the drawing (bloody great BTW ) does not clearly identify the capacitor connections. My "guess" is that the motor is a either a capacitor start/run motor (the capacitor is in parallel with the windings the whole time) or the motor is a capacitor start/induction run (the capacitor is only in circuit during starting & is disconnected by a centrifugal switch).

In any case, the motor is DOL (Direct On Line) started & as such, a circuit diagram can be produced provided that the exact motor type is known. Motors with centrifugal switches make a pronounced "click" a second or two after the motor has started. Does this happen?

First of all, I thank you all for your kind compliments. Stubbie is correct, I used Paint. It is both simple and easy to use.

To provide a little more info about the saw, it is is sort of a unique tablesaw. First of all, it is a 9 inch model. Not too many of those around. It was built in the mid seventies and features a direct drive motor ball bearing motor. It may be surprising to some, but most small tablesaws nowadays are not direct drive, rather gear driven with a loud universal motor. This saw is the quietest I have ever seen: it is literally whisper quiet. Not bad for a free saw! I cleaned it up and it looks like new. I believe the capacitor is of the start type, just by the looks and rating of it. Here is a picture of what it looks like:

Hi Junk

Yep I believe if you look at the top of the capacitor one terminal is marked C for common.

It looks like a vintage rockwell maybe they made it for sears?

I hope the poster comes back he is gonna love that diagram.

Unfortunately due to Thailands "steam powered" internet, I'm unable to download any of the pics that you blokes provide. It takes me about 5 mins to download 1 page. This is to do with the weather as I'm using a wireless hook-up. I'll keep trying.

Hey Junk
RCamp50 here the origional poster of this thread. Sorry couldn't get back sooner but had to go out of town. Buddy you are dead on and I want to thank you so much for solving a 2 year old delima. I can hardly wait to wire it all back up and start ripping some wood with it. Again thanks to you and all that responded to my question.
