I am putting 4.56 gears and a detroit in my 14b FF. I would like to know how you guys get the 350 ftlbs on the crush sleeve and how you held the pinion. My plan is to put the pinion assmbly in soft jaw vise, have a buddy hold the yoke with my 18" crescent wrench while hit the nut with my 1/2" impact a little at a time until the preload is set. ( I'll probably order a couple extra crush sleeves just in case) How do you guys do this. I have done this stuff on big ass New Holland,Ford,and Steiger 4WD tractors with the dealerships special tools, but never done a 14 bolt.
