The manual gives no absolute overall dimension for the shafts, and no inside dimension for the trans case. Just a .002 figure that I assume is endplay. Without the factory jig ,I can only compare what I had to what I have now.
Here is the procedure I used for installing the bearings. I start by using a washer to absolutely guarantee that no force is exerted on the outer race.
I freeze the shaft and use a heat gun on the new bearings. When the bearings hit about 150 degrees, I carefully line up everything in the press. It is easy to feel when the bearing is fully seated.
