Shaft thread size

[hawthorne90250]

while replacing the bearings on my Hayward superpump i slightly damage the threads on the rotor, the part the impeller threads onto. does anyone the the thread size so i can put a die on it and clean it up. pump is SP2607X10 2 speed 1hp.
Thanks

The shaft on a 56J frame motor should be 7/16"-20, national fine, right hand threaded.
