Out of the jeep I had the adapter bolted to the tranny. It was fine. I also bolted it to the transfer case. It too was fine. I have a gasket between the front bearing cone and the transmission and a gasket between the tranny and adapter. I used gasket maker between the tc and adapter. Is not having a gasket for the tc to adapter an issue? Also, if the tranny gasket grabbed the edge of the bearing when the adapter was bolted on, would that cause this? I'm just thinking. Also to add, everything went together very easily. I did not have to force a thing.
yea, the gasket i was thinking of was the adapter/trans gasket. I don't have one between the TC and trans adapter.
It sounds like both the trans and TC rotate fine individually and when they're connected when off the jeep, right?
When i installed mine i don't remember trying to turn the yokes on the TC after it was installed and before i connected driveshafts so i don't know how easy/hard they would turn. I'd check for you but i'm not going to be where the jeep is til Friday.
I did not have the tc and tranny bolted together outside of the jeep. I also did first notice the issue when trying to shift it sitting still. I haven't even put the shifter on it since I put it back in. The yoke is noticeably difficult to turn so I just stopped working on it before I found some dynomite to cure all of the issues. Lol. Is it possible that the tranny output shaft is bottoming out in the tc. This is why I was thinking maybe I was missing a shim or something.
if they're both still out of the jeep bolt them up & see if you still have the same stiffness. If they're in the jeep maybe you can back them out from the bell housing enough where the input shaft is disengaged from the clutch and then try to turn the yokes to check for resistance.
I recently switched out a T4 with a T177 (same as T176 cept for internal gearing) and had to problems like you describe with my D300 TC.
Ok. I loosened the trans to bellhousing bolts. There was no effect. It still took two hands to turn the yoke in neutral still. I tightened those back up and loosened the tc adapter to tc bolts... It freed up. I know my tranny tolerances are correct. I used feeler gauges on everything. What gives?
ok, got it narrowed down. Have you checked the depth of the TC input shaft vs. the length of the output shaft of the trans that would engage the TC? Also, look at the splines on the trans output shaft to see if there are any burrs, nicks, etc. that may interfere with sliding into the TC.
I just had a light bulb go off. Is there only one way that a clutch disk installs in jeeps. It's been so long I don't remember. I don't remember seeing a flywheel side or out side written on it. If it can only go one way and I have it reversed, is it a possibility that its pushing everything back by the trans input?
Deep lip of the flywheel should be facing outward but I don't think it can go either way if its like every other flywheel I've installed it goes only one way. The part the bolts to the crank should stick out some so it clears everything
