Old craftsman electric motor capacitor

[honza.vosalik]

I'm in need of replacing this capacitor. These were used for drill presses, bench grinders, tabke saws etc. I would really like to find something that will fit in the original space. Has anyone resolved this? I assume I'm not the first one to hit this issue. the capacitor is about 5/8" thick.

The flat ones are no longer available, a round one should fit in the base. Check out Amazon.

That old cloth covered wire is probably crumbling by now as well. You have a big project on your hands.

Keep an eye on your local Craigslist & Facebook Marketplace. I usually don't have any trouble finding these, albeit attached to an old table saw. I can usually get them for $20.

If at all possible, I'd suggest a new capacitor over a used one of unknown history. Capacitors do not age well.

But where can he get a new low profile cap with similar specs?

There's no way a round cap will fit into a CM motor base. The CM low profile caps barely fit unless you route the wires just right.

I used a metal receptacle box mounted on the back out of site to house the cap. Works pretty good.

The receptacle box sounds like a good idea to hide the capacitor, I like that idea.

You can also parallel multiple smaller capacitors if they will fit better.

Yea, I wonder if you can open that "sardine can", gut the insides and then populate it with enough smaller caps wired in parallel and then solder it closed?

Has anyone done that?

I've done something similar with vintage Philco radios that came with those old copper or brass capacitors.

Take a big hammer and customize the cylindrical one. JUST KIDDING!

Cant you fit a AC style oval capacitor in there?

This doesn't get you a cap and I don't know if they came in more than one value but
smeone is selling an old one describing it as a Craftsman motor start cap. From his description and the value clearly stamped in the sheet metal, it is 124 to 155 mfd at 125 volts. It looks similar to yours. Personally, I would not bother with an old cap that is way beyond likely to be good but I would try a similar value. Just google: "Craftsman flat motor cap" and have a look.

I ended up ordering a cylinder one. Waiting for it to come in the mail

You said you did not know the value. What size did you order?

I'm not aware of saying I don't know the value, sorry. The functional value is on the second picture. All I was hoping for was to find a cap in same/similar dimensions to fit the original space since the cylinder cap does not fit/is bigger.

Sorry, I must be seeing things.
