Nice find, hope it's the culprit.�
Is that a POS overseas replacement bearing?� How does the groove into the old bearing compare to the new?� I'm just wondering if the new bearing will be clamped down or will there be slight in/out movement of the outer race.

I believe that was a Nachi bearing but I don't remember. I always make sure they are US or Japanese so I know it's not a crappy Chinese one. I also can't remember if the snap ring was part of the bearing or separate in the kit.

I didn't compare the grooves on the new and old bearings. The "old" snap ring I reused fit snugly in the groove of the new bearing. No in/out movement.

I just went for a 30 mile rip at times exceeding 60 mph. So far the bellhousing weep hole has not shed a single tear. Let's hope it stays that way or I'll be the one shedding tears.

Well, son-of-a-gun.  That would probably do it.  Nice catch.

Wow Ryan, you found the needle in the haystack!

Just something to watch out for when rebuilding and I would have never thought to look at the snap ring.

Thanks for sharing -

Well at least you found the culprit...and you can expect little or no leakage now..

Nothing worse than looking for the source a problem but finding none....

And then just having to hope that somehow you fixed it....

I think I found the culprit. Looks like I need to seek out a new snap ring. Hopefully I have an old one intact in the junk bin somewhere.






Edit: I just scrounged up the old ring. Here's the difference in thickness.



Installed the old ring and the bearing retainer fits much tighter. That had to be it. I can't decide if I want a happy face here or an angry one  :) >:(

Probably won't make much difference. As we all know they aren't really much of a seal, it mostly depends on not being overloaded with oil for some other reason. Just be sure whatever you use isn't too tight.

What should I use when I put this back together? The felt ring shown in the previous pics with no rubber gasket or this one:

Could the case be cracked?

If it was out where water could have gotten in at one time it's a possibility...

Maybe you know of someone who could Magnaflux it?

Ryan,
I don't think there would be enough room for the bushing to slide rearward.  With a loose OD, it might spin a little.

Ryan .... Thanks for the picture.  I totally missed seeing that hole for the spring.  I knew that the angle was wrong with my bracket but there did not seem to be another choice.  As I tell friends working on cars, work with your eyes open.

Thanks.

Do you have the sealing washers under the three bearing retainer bolts?

Yes. Sealing washers were used.

A new potential culprit has risen to the surface.

This is the same Jeep that I just had the "bad" ring gear on. During the troubleshooting of that mess I swapped flywheels and installed the same pilot bushing numerous times between flywheels. Probably a bad idea and I wouldn't have done it if I had a couple extra bushings on hand. It was a new bushing so the ID was okay but the OD made it a little looser than I would have liked when pressing it into the flywheel for the final time.

Could the bushing have wiggled free? Is there enough clearance on the shaft for the bushing to slide rearward towards the clutch and fall out of the flywheel completely, riding loose on the shaft? I'm not sure if there's enough room there for that to happen with everything assembled. If so, with potentially 60 or 70 miles of driving it like that have I destroyed the needle bearings in the trans?

I'm curious now if utter lack of patience to sit and wait for a new pilot bushing to arrive has resulted in the latest catastrophe.

That part of my transmission is currently in pieces but this should show what you want to see

Ryan ... Yes, I would like to see a picture of how the throw-out bearing spring is attached to the face of the transmission.  It looks like yours uses something in the hole on that side similar to the hole on the other side for the clutch arm pivot pin.
