Topic tags/keywords: craftsman radial arm saw motor capacitor 11323100 sears question

Noob to this forum and needy of help.

I have a Craftsman Radial Arm Saw Model 113.23100 1977 vintage.

What I’ve already checked:
Has power to the switch.
Has power through the switch when turned on.
Reset button seems to be OK (has power through it). Don’t know how else to test it.
With switch on, power goes to the motor.
Checked capacitor with multimeter, started around 140 and bled down. So, it seems OK.
I blew the motor out with a compressor. It had some sawdust in it.

Any tips on what I could test next, or what the problem might be?

Ok, what I’m about to suggest is what I would do.... and it’s gonna bring the Safety Police to my door, but here goes.

This is assuming the motor spins free…

If you’re sure there is power all the way to the motor, I (that’s ME, not someone else) would use a pencil and standing BESIDE the saw (NOT IN FRONT) I would use the eraser end of the pencil and see if I could give the blade a small “boost start”. I would NOT put the pencil into the teeth, but rather use the eraser against the side of the blade.

DO NOT use something like a screwdriver so in case it DOES start, the metal blade would catch and take my finger off, whereas the pencil would break.

And standing BESIDE the saw means I could be back away from the saw, putting the pencil straight into the blade rather than be reaching alongside the blade with my arm.

If you can’t get it to work there is a recall that you can get $100 for it unless you did the upfit repair offered through the recall earlier. See link below

Does the motor hum briefly when you turn it on or just sit there doing nothing? If you get a hum and the blade turns free with the power off it is most likely a stuck centrifugal switch (inside the end cover of the motor) or a defective capacitor. Testing the capacitor with a multi meter won’t tell you much, but a few dollar replacement capacitor of the same size might fix it.

The centrifugal switch problem is usually a stuck or sticky collar around the shaft that needs to slide on the shaft as the motor comes up to speed to release the centrifugal start switch and disconnect the capacitor and start winding. If it does not return to it’s home position when the motor is shut off the switch will stay open and the capacitor and start winding will remain dis-engaged. The next time you try to start the motor it will fail to start. Usually just a polishing of that area of the motor shaft will make the collar slide easily again. Very fine emery cloth works best for the polishing. If you apply any lubricant at all, just use a very thin film of light weight machine oil. Apply it, and then wipe it off. The remaining oil film will be sufficient.

The shift turns freely. When it was on, I tuned the opposite accessories end of the shaft. No noise or resistance.

The capacitor did check out and discharged.

Is the centrifugal switch on the end of the motor, outside of the windings? I see some springs connected to a device.
