Thanks for the tip John. I have heard of people doing that but I don’t trust that method. I just bought 3 more of the two piece nuts I wanted so we are set.
The left hand nut does tighten against the end of the crankshaft so it keeps the right hand threads on the bottom part from unscrewing. That is way more reliable than blue Loctite. Both work but I would rather trust in the method we use.
