I just pulled the engine and tranny and upon seperating the two, I noticed that the sleeve that is over the input shaft and slides into the throwout bearing was broke off flush with the tranny. I have no idea how long it has been like that and havent had any problems. Is this something I can do without or do I need to have it replaced? Thanks in advance for any suggestions.

 

Lt1? or LS1? Either way its best to have it replaced.. The t/o ride's that so it remain's straight and true.. COuld or could not cause problems'.. hard to say. but its out.. might as well do it right!

 

I believe I have the same problem right now...Is it a 2-3inch long cylinder-shaped sleeve? If so, i coudnt figure out where it went either

yep.. its not that long..

 

Yep thats the right part, dont know how importantit is. Hope someone on here can shed some light soon. I took the front cover off and checked it out and it appears to be pressed in front of the input shaft seal. It has no wear narks from the throwout bearing riding on it, so I dont know. It is an LT1 car if that helps.

 

Yeah I tried pushing it back inside the tranny from the input shaft and I dont think its goes there..It didnt come from the TO bearing though so I dont have a clue. Im gonna try and locate some T-56 diagrams and see what I can find..Anyone else had this problem?

Looks like its right before the teeth on the input shaft in this picture..I'll try and find a better pic..

Come on guys, somebody has to have some clue as to what to do. Engine ready to go back in.

 

Found this...T-56 pic

Thats gives me my answer..My question is how the heck did that thing come out?? Im gonna try and push it back in there this next week..

Here's the answer guys: That's the input shaft collar that aligns with the inside of the throwout bearing. If you take it out, small movements in the drivetrain will cause massive amounts of wear to your throwout bearing and your input shaft. If you leave it in, but broken off, if will sometimes work great, and sometimes your clutch will simply refuse to disengage. The only appropriate answer is to replace it, but here's the bad news: It's a dealer only part that is $300+. It is the entire front piece of the tranny (that you bolt the bellhousing to). I had this happen to me!

Mine does not look broken off..Looks like I should just be able to press it back in there

I dont understand paying $300 for that piece at all...

What actually holds that sleeve on the input shaft?

Cody

 

It's actually a solid piece of metal, or at least it was on mine, that is part of the whole front metal piece on the tranny (that the bellhousing gets bolted to).

 

I cant believe I've never heard of this happening...Anyone else have any input on this?

Cody

 

Doesnt make much sense to permanantly install such weak metal. Gonna make a few phone calls tomorrow, will post what I find out.

 

Find anything out?
