Default OT - Start capacitors

Our small concrete mixer blew the start cap so we have to spin it by hand to
get it going. It is a 110 volt motor, probably 1/3 hp. It uses a 40 mfd, 400
volt cap. The closest Grainger has that I can find is a 43-50 mfd, 250 volt.
Would that work, or do we need to get a 40 mfd? What about the voltage rating,
is 250 ok since this is a 110 volt motor, or do I need to stick to a 400 volt

Default OT - Start capacitors

The tolerances for start caps is uneven. Something like - 20 % plus
100%. I don't think you will have any problem with using the 43-50
mfd 250 volt. If you rewired the motor for 240 volt operation, it
should still be okay. Typically the start winding is always used on
120 volts.
