And here's a link for capacitors *LINK*

You need a start capacitor rather than a run capacitor at a guess. I rarely see run capacitors (most I've seen were in HVAC use) but most machinery motors use start capacitors. In the link page the run caps are at the top, so scroll down a bit to find the start caps.

The capacitor should be labeled with a range of values in microFarads, usually abbreviated either MFD or uFD. Just match the range as best you can. Biggest problem I've encountered with replacing capacitors is one time the formed housing on the motor was too small for the replacement capacitor, but that is unusual.

At work we're only a 2.5 hour drive from El Paso, so if we order from McMaster and the product is coming from their El Paso warehouse we get it the following afternoon if the order goes in before 11 am. I believe they have a warehouse in Denver too, so you're about halfway between the two and should get the cap pretty quick.

The only thing about changing capacitors is to always avoid shorting the terminals. With a faulty one the odds of getting a shock from stored charge is minimal, but it is just a very good safety practice to make into habit. Treat all capacitors as charged capacitors and you'll never have a problem.

I took the motor to a repair shop (thank goodness it was not closed by COVID19!). They had to repair the windings. I just got it mounted back on the saw, but I'll wait until tomorrow to reconnect the wiring.

That motor sure is heavy! I got it from the truck to the shop on a dolly. Then I used pieces of 2x4 to lever it into position until I could get the bolts screwed back in. I'm pretty old and rather small, so I've had to learn many tricks for handling heavy or bulky items.

Johanna, I'm with you . . .

. . . about having to leverage large, heavy and bulky things. 2X4s are how I got my motor mounted in place on my saw, as well. When there's no one around to help, which is normal in my shop, you've got to use your ingenuity to move things sometimes.

Work smarter, not harder.

As I age, I am finding more and more used for wheel and levers and jacks and things. And my adult children. (While you are here son, Tip this giant stack of plywood so I can pull out the back piece.)

Anxious to here if your repair is successful. Keep us posted.

Big ol' motors

I couldn't help but think back to the ancient 36" bandsaw we had in my old shop in PA before it burned down. It had a 2HP motor that must've weighed 150 lbs. I wish I could still schlep stuff like that around.
