She moved!! Not under her own power... well, winching counts right?

Up on the trailer, finish one tricky spot on the exhaust at my friends exhaust shop... then I can hope the 7/8" x 20 TPI Atlas output shaft nuts I ordered from Parts Mike won't do what the 7/8" x 20 locking nuts that I had did...
Threaded the nut on by hand over 4 turns. Started turning it with the torque wrench and my shoulder whined (part of the story- not whining about my shoulder!

and I got my little 3/8" Milw impact out. Started zipping the nut in the rear output to get it up tight, then grab the torque wrench and be done... Well, the little impact started moaning after about 4 turns... I thought, "what the heck", put it in reverse and it could barely remove the nut... I was thinking NOOOOoooo... not on my bra d new 300M output shaft!!

Yes, three threads messed up... what happened? Looked at the nut and it looked good enough that you would use it if it came out of your parts bin!! Really!
Course nobody in our State has any Atkas tcase nutso I ordered a pair of standard Atlas output shaft nuts. Mine had the small indentation opposite each other on 2 sides which are the self locking part of the nut. It ruined the 3 threads. I spend almost 4 hours working carefully with a small 3 pt (triangular) file and a thread chase tool. Three of the other nuts threads on the frt output shaft tthe exact same number of turns as the rear output shaft. The threads were clean on the shaft AND rhe nut. Just something I check everytime...
So I"m good until I see what the new nuts look like. I was I'll admit ... a bit concerned for a couple hours... can't believe the nut was unscathed by the end of the shaft but it wasn't...
Anyway... whew. Hope I dodged a bullet.
