I need to fill the hole on the transfer case, and of course that would be with a Warn overdrive. I have only had the overdrive for a few seasons, but it goes very well with the 3.15 low gears, because 1-over is like my old low of 94:1, and is used much more than 119:1. Anyway, when I removed it, I noticed it was a little loose, and on inspection, I was missing a spacer on the adapter spud shaft that allowed it to move in and out a little. I think that would explain some noise and some hard shifting. So, I need some small parts. I got out my vintage Warn book and ordered some parts from Advance Adapters.
Parts from AA arrived neatly packaged. I am sure glad I can get these from AA, and not you-know-who. I got new synchros, thrust bearings and races, and the spacer that goes where the PTO output gear was. Yes, for the first time in my life an overdrive on my jeep does not have a PTO on it.
Disassembled the bowl gear to replace the bad bearings in it, and installed the new synchros and little dogs in the main housing.
Installed the bowl gear in the transfer case and torqued to 100 lb. I got pretty lucky, as the washer and snap ring went right in on the first try. That never happens when doing it from below.
I installed the main housing, and dug up the rear bearing cap, that I took off when I did the PTO. Also connected the shift linkage. I hope this little tune up will make it shift better, and maybe quiet down a little. One more step towards getting the tub on.
