Yes, I know ,but 120volts is only the average not the max .In ac
sine wave
the volt starts at 0 then it goes to 177v and back to 0  then to
-177v  and
back. It is an average of 120vac so the cap is subject to the volts of
177volts for 1/60 sec for x 30 times.....

This may be true, however motor run caps are rated in AC Volts RMS,
they are slightly over-rated for the designed voltages, i.e, 165v cap
for 120v power, 370v for 240v power, etc...
