Now just have to find time to schedule the uninstall\correct\reinstall procedure...

Good news is you now know what it is. The Bad news is now you have to find the time to actually fix it.

Pardon my ignorance w/the t56's & the TO bearing pieces..... What is the red shrapnel I'm seeing?

It's powder coat from the back side of the pressure plate. When the bolt broke, the fork pressed up against the spinning pressure plate, peeling off the powdercoat and a few aluminum shavings.

That might just happen tomorrow, I've cleared my docket!! :D

I think the hardest part might end up being the retrieval of the two broken bolt pieces.

Might try to re-engineer the setup a bit while it's out also.

Might...Come on we have seen this build of course you are going to re-engineer it.

Well, this should be fun to get out...

Had a very liberal coat of loc-tite on it when it went in the last time about 7 years ago...

Eak - that does not look like fun

Assuming you know this but sharing for all, a little heat helps with removal of items that have loc-tite on them.

The nuts we tried to weld to the stud were so small they melted down before the weld would burn into the stud

Turns out, several drill bits and an easy out with assist from blue wrench was the answer.

New bolt procured and ready to put all back together now.
