grinder capacitor

[bob15]

Last week I picked up a couple old Stanley bench grinders. They are identical 110vac 60hz Kingston-Conley made machines. I would like to replace the start capacitors on both of them, but am unsure what size to buy.

One grinder's capacitor reads:

Mallory Electric (still paper wrapped ~ 1940's maybe??)
107 MFD
110 VAC
97495 FF

The other grinder reads:

Baldor? (paper is oily and hard to read)
130-157 ?FD (maybe mfd)
110/125 vac
60 DY (definitely DY and not hz)

Which start capacitor should I be buying?

Temco has:

108-130 and 161-193 both 110vac....or should i be looking at something else, size-wise?

I'd get the 108-130 since that sounds like the original cap. The difference between the two isn't all that great and the value isn't super critical.

However I'd up the voltage tolerance to >110 VAC.
