Ok, so even with the output shaft bearing installed correctly, the center support is still sitting up what looks to be .020” too high, resulting in the snap ring not seating correctly. I verified that the output shaft is making contact with the bearing that rests on the no walk bushing. I can see it functioning correctly through the access hole The thinner snap ring that rests under the center support is installed correctly, in the proper notches and sits flush. . The roller clutch looks fine, nothing missing. Here pics of everything. Sun shaft left off to better show position of bearing, but it is installed in the correct orientation when testing. What is causing the center support to sit just high enough to make the snap ring not go in correctly? When installing the bearing that goes in between the sun gear and the center support, I'm using trans gel on the portion of the bearing that goes into the center support. Then the other two parts of the bearing rest on the sun gear as shown. Trans fluid is used on all the bearings so that they are silky smooth. The bushings in the sun gear shaft, front planet, output shaft, and center support all look to be installed correctly an are not sticking out past the edges of the component they are installed into. I'm not sure why the new bushings look so bad when plenty of trans gel and fluid was used during the install on where they make contact.
The beveled snap ring goes into the case as it should when installed by itself. The reverse band has been left out during all this testing.
I plan to remove the no walk bushing an re-apply the loctite for a re-install since I backed it out a little bit earlier, but right now I need to solve this issue of why the snap ring won't seat correctly. Only then can I proceed with utilizing the pocket in the front planet an putting the bearing/shims back in to verify carrier to center support float, followed by adjusting the rear end play.
Check out page 49 figure 62 in the ATSG manual. Why don't they show the .042" thick washer (#252) that goes in-between the needle bearing race (#249) and the rear ring gear? Mine is in there ofcourse, but I was surprised to not see it in the diagram.
