Take care of Leon, Brendan. I'm sure you will.

No mods.
I found the older thread on the process of getting the newer engine in there and there was a mount replaced. So you were correct.

I am still trying to decipher the vibration. Last time I had a vibration that seemed similar it was an injector. Electrical connection issues. I don't know if that is it yet.

I do have a TT I can rebuild, and I have boxes and boxes of other parts I would never probably otherwise use, or can simply switch out and repair the outgoing part for my other uses.

I have had two separate 928s have some TT issues - but just noise. Make that three. TT noise - a growling - but when I get them personally, it seems to go away - and never come back. Usually from simple low-usage to high usage, I think the bearings "get better" or something similar.

I don't feel it happening this time. The vibration "ramps up", but I have not quite been able to separate it from the feeling of vibration possibly from the clutch.

I just want to fix what is broken. I can do that without disassembling everything you know. I am actually quite good at it. :P I love having a 928 around again, and I think I could do this somewhat noninvasive-like.

I have replaced the alternator for one that I had that was newer and tested well - so that was good to have the spare parts for that. I think I will be replacing the PS pump and cleaning up the mess its made in a short time.

There are some pictures of a lone 928 from this morning's new Year's Day drive. Can you spot the Cashmire Beige?

The old very brown 1980 has a weak front TT bearing was making some noise and had slide back toward the center ....At 928 Int one day Mark and I put it on the lift dropped down the front of the TT and pounded in another carrier and new bearing......that was YEARS ago. Still have the bearing hum with the clutch out but the shaft is now centered by the additional bearing and no vibration. Thanks Mark

How come my "What if we just........" ideas never work out that well.

That sounds like it might just work.

Brendan,
Great action shot!

Interesting to see proof of you actually driving a 928. Feels good ey?

Hmmm. that add an extra carrier and bearing idea in the TT sounds interesting. Would there be any benefit to doing that on just any TT. Is three better than two in the AT cars? Maybe 4 if you do one at each end?

Default Insults..??

Hey..!
I thought we all agreed that calling names and insulting folks was classless and of no benefit to the community at large...???
We are supposed to insult the corvette guys.. not ourselves..!!

While Adrian digs his ban-hole even deeper, and increasing his useless post count, and indeed his own uselessness, by insulting Gretch and actually suggesting someone else should kill themselves, I will give an update on the thread title.

Over the last two weeks, I have done some more work to Leeroy to bring some things to where then need to be.

I attempted adjustment of the clutch, and while it is better SOMETIMES, sometimes it is NOT. Therefore I am thinking about taking the (nearly new, except for the bearing) clutch pack down and using another release bearing I have, and another intermediate shaft. Those are two possibilities for the clutch hanging up occassionally.

The pinned front bearing seems to have cured SOME of the higher level vibrations, though the gearshift still vibrates most of the time. If the clutch pedal is even slightly released, a low frequency undulating vibration occurs, and I assume it is something still in the TT, or the clutch area.

I also replaced the starter with a newer rebuilt one, as well as the steering pump (thanks Mark). At the same time as I was doing all this I noticed that the steering rack bushings on two of the ears were totally like jello - so I took the rack off as one piece and replaced them with solid bushings I had from the 78. I will get better versions for the 78 from Roger now. The inner and outer tie rods were in very good shape, so I did nothing to them.

I bled the brakes, replaced all the power steering fluid because I removed the rack and replaced the supply line from the metal canister to the pump, and changed the oil and transmission fluid.

It is my belief that the car needs shocks. I found a very good price for lightly used bilsteins from a wrecked GT in LA, so I think I will use those.

But more pressingly I think I really need to get the clutch working properly.

Great to read about the attention you are giving Leeroy. If each person who becomes his caretaker does as much as you he might end up as one highly sought after car.

Unusual color. I like it. Especially with those black wheels.

Keep tweaking it a little, make it functional!

Clutch intermediate shaft polish and lube might help intermittent clutchency.
