741 - crush sleeve and shims?

The front seal doubled the inch-pounds on the 9 1/4 I just finished doing. With the crush collar eleminator and New bearings it was set at 20 inch pounds. I put the new seal in. tighten it all down checked it and it was at 40 so there is a reason that you check it without the pinion seal.

the seal will maybe add 2-3 in/lbs to the rotating torque --- the reason for the doubling of the torque was when you set the initial preload before installing the seal you must torque the pinion nut to at least 150 ft/lbs to get an accurate reading of the preload -- then when you do the final assembly the torque will be the same except for the 2-3 in/lbs for the seal.
