I just replaced my jack shaft on my 2014 m8000. Putting back to get her and on the tensioner time of the game and I m uncertain of how to put in in. Do I set it with proper tension and then it will take over from there or do you put it in loosely ( which does not seem right ) and let it tighten up some how on its own. I have it right now with about 3/8 of a inch of play on the non tensioner side is that to tight to start with? Thanks for your help in advance
