Outlaw, sounds like this information will help you - I'm going to attach the instructions from the shop manual. This should help with your questions. Note that the left photo is the first "page", the middle is the second and the third (right photo) is the remaining information from the Shop manual. The "installation instruction" will provide some insight, I think. Tightening something up until it stops and then backing off until the cotter pin can be installed seems "strange" but that's what it says! Good luck and happy bolting.
