Starting Capacitor?

[cj7zrcool]

I have a very old Rockwell 14" band saw that will not run right. I pulled the motor off it yesterday and everything seemed in good working order until I took the cover off the starting capacitor. The leads were either completely rusted or burnt off. Where would I find a replacement? I checked Amazon and can't seem to find a direct replacement and I don't know enough about them to look at one and say, "yeah, that'll do." Somebody school me.

This is off the old one:

STM
Motor Starting Capacitor
4207F-171
161-180 MFD
110/115 VAC
1160-6709

If you can't find it by searching 4207F-71 I would try searching for the saw model parts and see

Hopefully someone that knows more about capacitors will see this and chime in with better info

Try Grainger, they have a lot of capacitors. I bought capacitors for two of my shop air compressors and then my shop fan from them.

This looks close.

This one should work. It may not be need but wouldn’t hurt to add a bleed down resistor.

Yeah, that's the same one I pulled up but there's not a direct cross reference and the numbers are off a tad. Just wasn't sure if it was close enough. I just don't want to do anything to burn up the motor.

There is a slight difference in the farads, but that should not be a problem.
If the dimensions fit your application, and the terminals match your application, you should be good to go. If the connections don't match, you could change the terminals on your wires.

Thanks, I just ordered it.

It will work just fine.
