Review on Universal Outside Standard Repalce Restore by Tre Boyer

Saved the threads on my 70 year old tractor axles that have 2 keyways! You just keep working it clockwise, then counterclockwise into the keyways, stop and start again... I used the shank of a small tapered file to push it through the keyways until the threads are clean. The tool only works in one direction, and rocking the handle back and forth helps negotiate bumps. I removed the die and cleaned the internal threads on the nuts. Now smooth as butter.
