i was looking at pics and thinknig bout this. so the way it sits now. with the small bearing in my Tcase and the large gap. I am guessing the nose part of the main shaft is not sitting fully inside the input shaft, it is only riding on 3/4 of the bearing face of the 22 needle bearings in the input shaft. So with the larger bearing it will push the input shaft farther back to fully seat the nose of the main shaft? Is this correct thinking? I am just trying to picture how the larger bearing makes a differnce.
