First of all I want to think everyone for their input .I really appreaciate it. This is what I did...I took my new nut to my work and the machinest took a thread pitch guage and confirmed it was a 18m x 1.0...I told him about my situation and he told me the same thing that Toybreaker said...If the threads weren`t to bad on the shaft I could possibly take a triangle file and file the threads and stand them back up some what...He gave me a triangle file and when I got home I went and took my time and filed the threads back up and put the lock washer on and then the nut...Wow it went right on with no problem...I tighten it up pretty good, bent the lock washer down...I`m ready to try it...I will try it tomorrow.....Thanks guys,I hope I have a chance to help someone like you all have helped me...
I`m still going to check these places for a die rethreader...just in case.
