Sizing starter capacitor

Sizing starter capacitor

Sizing starter capacitor

(OP)
Hi, I'm hoping I can find some help here. I have a fan that recently had the motor's starter capacitor fail. Unfortunately the capacitor is so old that when I tried to clean the dirt off it the specs came off as well and I have no idea how many microfarads it is. The motor is an Emerson model K5 5HXKWN-8586. single phase 120, 1/3 HP, 5.7 FLA, 525 RPM. I couldn't find a service factor so Id assume 1.0. I'd greatly appreciate it if anyone could tell me the size of the starting capacitor I would need.

Also I tried to find the locked rotor current but that wasn;t on the nameplate.

RE: Sizing starter capacitor

Hello

Doing some googling I'm guessing the motor to be ~.612 Kw with power factor of .85 and according to a sizing chart it would require 500/580 uF cap. Perhaps one of the pro's will chime in but here is the link I used.
