Vico Ultimax Pump and Motor 370V Capacitor

Rebuilt my vico Ultimax 5hp.. New bearings and seals. Went to dry test and it hums. If I turn the shaft the capacitor kicks in and will run, once I shut it off it just hums until I turn the shaft. I think I need a new capacitor. Before I order one online I would like to make sure I’m ordering the right one. I’ve attached a photo of the one I pulled off my pump. 370 VAC 50/60 hz. The large print number 313, but the other is B 70 C.
