Bad throw out bearing?

Really? Does it explain why?



Is that specific to these flywheels, or a standard across the industry? I’ve never had one done myself, my manual vehicles still have their original clutches, but I've known a few who have had flywheels turned, and lightened, but that for a different reason.

read post #16. yes as far as I know it is just on jeeps. I dont have time right now to look it up but look at the manual in the resources section here and it tells you why.

from the service manual....

Minor scratches, burrs, or glazing on the flywheelface can be reduced with 180 grit emery cloth. However, the flywheel should be replaced if the disc contact surface is severely scored, heat checked, cracked,or obviously worn.Flywheel machining is not recommended. The flywheel surface is manufactured with a unique contourthat would be negated by machining. However,cleanup of minor flywheel scoring can be performedby hand with 180 grit emery, or with surface grinding equipment. Replace the flywheel if scoring isdeeper than 0.0762 mm (0.003 in.).Heavy stock removal by grinding is not recommended. Excessive stock removal can result in flywheel cracking or warpage after installation. It canalso weaken the flywheel and interfere with properclutch release

What am I looking at here? Anything wrong with the clutch? I’m putting a new one in either way, just interested

Getting that transmission out without a transmission jack was quite difficult, but I did enjoy it for some reason. Was a fun challenge I guess. Will be renting a transmission jack from sunbelt for when I put it back in.

Also, this is in the top of the box on top of the transmission that the actual stick part of the shifter goes into (sorry for lack of fancy terms there, I’ve got no idea what I’m talking about). Hopefully you know what I mean. There were some metal chunks, but when I rubbed them around in my fingers, they kinda broke apart and disintegrated. Anything to be concerned about? It seems like an odd place for that stuff to be, it’s so high up… I don’t know how it would get there.
 
Shift tower. Boot(s) might be ripped or torn. Bushing in there that might need replaced if your shifting feels sloppy. I replaced my stock tower with a B and M short throw...love it.

Clutch doesn't look bad...but yeah you're there so replace it.

How does the throwout bearing sound? Smooth or gravelly? How does the pilot bearing look?

Nice quick work!

What fluid are you running? Good time for fresh stuff.

I pulled and reinstalled my AX-15 a number of times with nothing but a floor jack. It's pretty light as transmissions go.

Might want to preemptively change the output seal.

The boot actually was ripped, and I was planning to buy another, but why would that cause the metal bits to be in there?

What does the bushing look like? Shifting never really felt sloppy to me…

The throw out bearing had fallen apart. When I took the transmission out, 4 of its ball bearings were sitting in the bottom of the bell housing, and the cover of the bearing was just hanging there. I guess that was my problem? Otherwise though, the individual pieces of it looked okay.

I just put the redline transmission fluid in a few months ago, so shouldn’t need to change it, right?

Thanks for your help!

Redline... perfect... shouldn't need to change it unless you knock a bunch of crap in from that tower.

Bushing...goes on the end of the shifter...what engages the gears in the sliding rails below...

What does the tip of your shifter look like? End that goes in the transmission?

My guess is the tower has some wear and that's where the metal is coming from.

There's also a metal seal between the tower and transmission. Mine was missing. I believe that also sets proper spacing. I couldn't find a replacement and that contributed to me just buying the B and M.

That and my transmission shop was finding every excuse for them not rebuilding my AX-15 right...I ended up reinstalling 4-5 times...they did it 2-3 more times. Last round they hairline cracked the tail housing and it really opened up and fluid poured out when it got hot. At that point I was done and ordered a new one from Advanced Adapters.

From what I remember looking at it yesterday, that part looked to be in good condition. Not gonna go check now because I just had surgery this morning, but might go take a picture later in the day.

Would you be able to see that in this picture?

Not ready to spend the kind of money needed for a b and m shifter right now… maybe sometime in the future.

I’ll clean out that tower on Monday before reinstalling everything. Thanks

Nope... that's where it goes...need the stick...

No need to buy the B and M. I mostly bought mine troubleshooting my issues.

Feel better!

It is specific to the TJ whose flywheel has a special dome/convex shape on its surface that machining would remove. You can read the official TJ Factory Service Manual to confirm this.
 
And which part is the metal seal you were talking about?

It's between the tower and the transmission...you didn't take it apart...I swapped my transmission as a core...so I had to move my tower and bell housing to the "rebuilt" one.

No need to touch it.

My new TOB came today. It is clearly not symmetrical. Is this normal? Should I return it?
