Default Will this capacitor work?

It looks ok, with one possible problem. The capacitor should be
non-polarized.
https://en.wikipedia.org/wiki/Motor_capacitor
Start capacitors above 20 F are always non-polarized
aluminium electrolytic capacitors [4] with non solid
electrolyte and therefore they are only applicable for
the short motor starting time.
I dunno about the "non solid electrolyte" since the capacitor in
question is a "solid" polypropylene metallized film dielectric. Oh
well


The capacitor in question was listed as a motor RUN capacitor,not start.

The top of the data sheet says RUN so the non-polarized electrolyte
part should not be in question.


Oops. I stand corrected. I wasn't paying attention to the
differences between start and run capacitors.

Run vs. Starting Capacitor

In any case, the data sheet is the correct one for a run capacitor:
