Problem NOT solved! same problem. started out on the jack stands and Ebrake on , no problem, as soon as i got down the street, the same problem. vibration in the pedal, tinney rubbing noise (hig frequency) and the clutch started to be grabby. all i can think of is that stupid little part , the clip retainer ring came out again. went on a longer drive in denial, and it got so bad it was like having no clutch, unless you turned off the engine, put it in gear and then let the cutch out. still kind of grabby too.

if its not the clip ring when get this thing out for the 4th time, im going to set the entire car on fire!
(kidding)

If it is the clip ring, i guess thats what i get for using a used 3 dollar part. if it is not, then who knows!
ill have it appart today.
UGGGGGGGG

Well, im getting pretty good at getting the clutch in and out. got it out in about 45mins now.

anyway, the good news I found the problem, bad news i have a problem, AGAIN!

the little $3 clip broke this time!

so, its all making sense. now, if i could get my head ot of my Axx and learn some patience, i could have just waited til the new clip got shipped to me and THEN reinstalled!

does anyone think the T/O bearing should be replaced with a new/rebult one??

Yes .. I do, but you're wasting your time if you don't replace that PP ... the fingers on it are shagged!

mark kibort

Thanks. just felt this T/o bearing and its marginal. i dont want to do this in another year , so may as well just replace it for the bearing sake. the groove looks still pretty good.

as far as the pressure plate, i havent seen any of them that didnt have the wear marks from the contact washer. its been working welll, and the guide tube should make sure things are centered. pulling the clutch apart, the shaft slides very easy out the pilot bearing and the connecting shaft coupler slides off and on the short shaft with no resistance. (very centered). i might take the chance on the PP, only becuase its expensive , mine is working, and its a liittle special.
(however, i think i know how they are making them now! )

Ok, i just got the new assembly into the racer! thanks 928Intl for the rebuilt clutch T/O bearing!! nice and new!! the ring clips are KEY on this job! a new one goes in so much more firm and snaps into place with authority!! never use a used part here again!!!

so, thats 4 clutch jobs this week. i hope i dont have to do that again. however, got pretty good at it. out in 1 hour and back in within 1 hour too. hey, dont laugh but that jb weld trick doesnt hurt at all. just a dab to hold it all together when you are putting this stuff back in the car, works well. and the second time , there is enough residual jbweld still there to make a tigher press fit of the assembly.

anyway, its in and feels a lot better.

going for a test drive now.

UNREAL!! it is smooth as silk! Just got done beating on it for an hour. too much fun. its smoother than its ever been. it always had a vibration from the accident and thats what it was along.
it wasnt the fingers of the pressure plate worn,
H tabs, INT plate
bent flywheel or crank
It WAS the littel retainer ring that was failing. it was jacked up by removing it and what it did was position the T/O bearing at an angle to vibrate when idling, put uneven pressure on the discs as the clutch was released (grabby clutch) and not release the discs so it felt like an INT Plate issue. with a new bearing and clip, along with a good shape large pull-washer (with the tooth), it shifts so smoothly, spins with 0 vibration and relases the engine from the power smooth as silk!

All because of the wear and tear of a $2 part! the retainer ring. did the bearing as well, as WYAIT, and certainly it makes it even smoother as the old bearing wasnt bad, but had a little bearing noise. heck, it had 7 full years of racing on it!

Thanks for all the help along the way on this problem

Just glad the nightmare is over!

BY THE WAY: the H pinning has worked out very very well. gap still at 1mm, and thats fixed. and remember we were talking about when that might not be a good thing after the discs start to wear, but did some checking on how much wear that would have to be. basically, you would have to skin the clutch discs pretty badly for their not to be enough room for the INT plate to move rearward and make pressure contact. sure its a hassle to drill and pin, but it works. Just an FYI.

Mark:

You might note, for the future, that no one on this forum claims to be psychic.

We're all just coming up with potential possibilities when someone asks what could be wrong with their car.

You beating on people's ideas and then putting emphasis on how wrong they were, when you finally take it apart for the fourth time and do a "short term" repair, make us (or at least me) not want to help you, very fricking much.

Sometimes it might be better to tone the ego down a bit and dig really deep to see if you can find any class.

mark kibort

Greg, i appreciate the help. I know you dont like my pinning of the H's but i took it a little perosnal when you suspected that as being the issue. others follow your lead, you have that pull here. the H Pinning is a great solution but a hack, i know, and is a hassle, but there is no downside over time. im proving that now.

heck, most of the other solutions that were suggested and wong were my own and i APPREcIATE all the suggestions. It really helped me think about what could be wrong. the worn fingers had me spooked as well. Im sorry if it came across as a thanks but no thanks for your help. had it not been for the grooup, i would have spun around for an even longer period of time. nice to rule alll the things that are possible, out. torque tube, plastic bushing, replace the entire clutch hydralics, etc etc!

anyway, I think we all know one more possibilty that can cause a major clutch malfunction now! that snap retainer ring is friggen IMPORTANT!!! so is that thick washer.

So, thanks again for the help and the suggestions. I know i got a little short about the H adjusters, but its probably the only thing i know REAL well on the 928 now! I take a littl pride in being able to figure that one out and solve a major issue, without having to replace the INT plate!
by the way, i could have replaced the INT plate with an almost new one. I didnt, i believe it the pinning so much. But then again, i also believed that the used retainer ring would work, even after being damaged. One was knowledge and the other HOPE!

I just hope this helps someone else with the problem in the future. in any case, replacing that thowout bearing is a wise thing to do!!!

by the way, ahemmmmm! Ill try and tone down my ego a little, a little. again, didnt mean to put down anyones ideas, because all of them were appreciated. By the way, what do you know about big egos anyway ????????

the flyin' scotsman

Very well said Greg..........I followed the thread for the technical interest but yes stopped participating weeks ago after being told how wrong we all were.

mark kibort

I didnt like the flavor of some of the posts pointing fingers at a mod that wasnt popular and would have nothing to do with the problem. more like a dig on something that clearly works. I took it a little personally , and probably shouldnt.
Its a discussion. no need to jump on any band wagons here. just trying to figure out what works and what doesnt, and find solutions to problems. there was one post by greg that said that pressure plate would "never" be able to spin true with the grooves.
There are a lot of egos here, if you havent noticed. just by your post alone. what does that do for you? make you feel better? endear you to Greg?
Its the rennlist garage here. cant we all exchage ideals without the personal attacks?
I just read everything past page 5 and it all seems like a pretty good discussion where greg and many others added some great advice and suggestions.
Dan and greg were right in the end. it was all things having to do with the T/0 bearing.

Glad you worked it out MK, your tenacity is inspiring.

GregBBRD

I personally think you (and others) mistake my knowledge of these cars for ego....

I've been doing this a few days, now, and I do know a bit about the topics that get discussed.....

And do not suffer well with fools. I'm abrupt with them.

I know that there are a few people here, that resent my knowledge. Some days those people make me want to just give up.

I could easily become a vendor that does nothing to help others, but simply sells (you know who this is?). That would be easy and require a lot less time, on my part.

However, to let you know a little bit about me and what makes me tick....something that very few people, here, have a remote clue about....

I'll share one of my life's mantras:



People with large knowledge share that knowledge, with others.

People with little knowledge never share.




You can call that "ego", if you want.

mark kibort

I think we know why many of us are here. I subscribe to the same montras as you do below. Now, the ego thing.............well, you know what im talking about. Sometimes things are not as white and black as you may think. Im all about looking at all the possiblities, and options. anaylizing the data and making decisions not based on feelings, (although we all do that sometimes) but based on facts. my HP vs torque discussions are a great example of that. people will use their feelings to try and make decisions that go against facts and laws of physics.

We both have made statements regarding issues that have been wrong before. thats ok. it doesnt discount your knowledge or stature here on the list, it actually enhances it because it shows you are trying to think outside the box. a know it all is usually not. people that are sucessful, make mistakes. YOU learn from those mistakes!

But, when you say something is the way it is and there is no other way, or answer, you BETTER be right! The ego part comes in to where you may have said things that were NOT entirely correct and were actually proven wrong. I know you are trying to help, but it comes across as a ego based comment. The H's and pressure plate finger wear is an example of this. I think we all appreciate your help here, more than you know. we have a lot of egos on the list here, but thats the nature of this kind of group. we are all car guys and most are extremely competitve and have strong egos. its a good group. it pushes us to be at the top of our game when discussing things. BUT, it can create an environment that steps on our feelings so we all have to have a tough skin to survive here.

anyway, i think we get you and appreciate that you help and are here.

Again, thanks for pushing me to figure this one out, even if it was using the hard way! Whats great about this list is that most of us CANT replace everything when something goes wrong. if we could, we ALL would just take cars to your shop and say, "fix it and send me a bill". there is also a bunch of us that LIKE to solve problems and help others. its an amazing group actually. so, in the end, we learn, listen , fix and help others do the same. not a bad deal for anyone here!
