Put a wrench on the nut . If its a 1/2 wrench it's a 5/16 stud, 9/16= 3/8 stud, 5/8=7/16 stud. Next time split the nut with an abrasive blade on an air die grinder or Dremel tool . You'll save hours of work ....

Parts lookup is a little vague, but apparently they are 7/16" NF 20 TPI, with a flange.

Current CIH part # is 682987C1.
Look under Key 2.
