    Don't know the particular motor, but it seems possible that the failed
capacitor is a "run" capacitor which should be constantly  in circuit with
the second "run" winding  to provide phase shift to that winding.  The motor
would be in essence a pseudo two phase motor.  Failure of the capacitor
would explain the overheating.  The voltage rating of 450v also indicates a
"run" cap, but 60 uf seems a bit high.??

Failure of a "start" cap would mean the motor would not start, just hum &
heat up.  I would expect a "start" cap to have a value of 150-200uf & 250v.

Have you considered contacting ONGA or one of their agents?
