Craftsman motor 115. 5831 need help!

[danandmelrod]

Hi everyone,

I recently picked up this motor at an estate sale but it needs major work. The cord and switch are missing. I’m planning on trying to put it back to safe working condition but don’t really know what in doing. This is my first restoration attempt.
I currently have it disassembled and the cast parts bathing in soapy water in my crockpot. I’m trying to remove the painted parts without damaging the original finish. I would like to save the original finish so it can match my Early 1940’s drill press. It has a newer style motor that I would like to replace it with this one. To keep it all period correct.

That part I will need help with the most is the wiring. I can’t seems to find a diagram and since wires were cut, I don’t know where they go.

Is it worth saving?

If anyone who has restored one can chime in or lead me in the right direction. I would greatly appreciated. Thank you all and keep those post coming. I enjoy reading about everyone’s cool tools. I will post plenty of pics.

I would like to pair it with my drill press

Here is my drill press.

I believe the wires should be attached to this plate?

Here are a few pics of my 115.5454 when I r&r'd it. My wiring was a mess when I took it apart. It looks very similar to yours. Hopefully they'll help. Yes, I believe it's worth saving if all the parts are there. I love mine. It's nice and quiet and works well. I'm about to r&r another motor for another drill press I just picked up.
I'm going to post most of my motor related pics in case you need to see something besides the wiring:

Cleaned, new wires and ready for re-assembly:

Did your motor have a capacitor? I think danandmelrod's does have one. If it doesn't and is like yours here's a wiring diagram I came up with for my similar model.

I believe in theory they should be the same/similar. If it has a capacitor I would need to crack open one of my other motors.

A multimeter would be a great help in figuring out what goes to what...

Mine doesn't Michael. I couldn't see his too clearly in the pics and there doesn't seem to be a ton of info on-line about his part number.

I just wasn't sure what this was?

I suspect you're right that it's the capacitor.

 

[danandmelrod]

Thanks Sgt and Michael. Mine does come with a capacitor. I hope it works.

Sorry, my garage door was covering my overhead lighting. I will take better pics in sunlight tomorrow. This getting dark at 5pm *****

Hey Sgt, what did you use to clean your contacts and coil? Did you replace your bearings?

Thanks again guys. I really appreciate it.

Here is a pic of the parts being removed from their soapy bath. It was covered with 3 layers of paint. For some reason the before pic didn’t come out but here it is after. I’m just going to protect with some gloss clear coat.

Hmmm I'm hoping you have a volt ohm meter? It would definitely help because then you could get the basic schematic drawn and use that as a reference. Having said that here's something that might help?

I don't think yours comes with that thermal switch though...

I just used air and regular old spray contact cleaner. I didn't have to replace any bearings.
