348 clutch, to resurface or not...

From your pics it looks like my plates had more heat damage than yours and the shop I took them to had no problem grinding them to "as new" condition. What can't be determined from your pics is the depth of the scoring from the rivets and/or warping of the plates - only a qualified clutch shop with the parts in hand will be able to determine if there is enough material to grind it out and leave the stack height within spec.

 

If the rivets have worn into the flywheel and intermediate plate, then they need to be machined brother.
Should be someone in your area that can machine them both. Can only go so far to stay in specs.

Replace the clutch plates with new ones or have the clutch plates re-surfaced. There should be someone in your area that can re-surface them.

Then.....its needs to be setup before fitting to the car.

 

I haven't had to replace my flange/release bearing, but there are guys on this board who have used the Hill Engineering units and feel they are superior to OEM.

As for servicing the flywheel, Fchatter Gimme Fuel has an informative tutorial for anyone who would like to know what is involved:

Removing/Cleaning Flywheel
Regreasing Flywheel

 

My clutch burned out while driving across Italy last summer - 1st day of our supposed honeymoon!!!!

It required a 'complete rebuild' which added up to 6,500 Euros - a bombshell just a week after our wedding!

Otherwise, after nearly 3 years owning the car and driving it across Europe nearly twice, I have absolutely had no problems whatsoever except the ridiculous little mishaps which happen with any other normal car.

 

6,500 Euros!!

I just choked on my chips!

 

Ok, the rivets wore into the intermediate plate and scored it. We need to mill it down but don't know the necessary specs in order to do so. I've called around, but no one has answers. Anyone?

 

Whatever gets machined off the intermediate plate, needs to be taken off the flywheel to maintain the 'step'.
Im sure your machine shop should understand that. There are a few cars out there with this type of setup, so they have probably machined something like this before.

I do not have the any specs sorry mate. I had my flywheel and intermediate plate machined here, then I sent them down to the guy who made my clutch. He set it all up and posted it back. I then bolted it into the car and away we went!

 

In case you all missed this, this is a really really bad bet.

Sounds to me like you should not take a chance if the flywheel surface has been so visibly scored. Definitely need some expert to examine the wear for an educated opinion on this. Otherwise, pay the freight and replace eveything. FWIW, if it were my car I'd check the old parts lest I get head slapped by Stooges Plugzit and Ernie first.

 

Hey look at post #4 Which I was referring to. Drew's post is after my comments. I'll still stand by my bet with rick's intermediate plate. You need to evaluate Drew's plate before you can write it off. But I bet you personally that if I stuck Drew's plate in your car with my homemade guts you will tell me my junk is better than the Ferrari OEM clutch you have in your car right now.

 

Page D6 in the 348 WSM indicates the set-up height measurement must be within 47 to 51 mm. You can check out the diagram at Ricambi's site: http://www.ricambiamerica.com/wsm/348/348index.htm

Navigate to section D, index, then click on "Clutch Fitting" (third one down).

 

How much pizza and beer do I need to bring over to bribe a tech session day with you and the stooges?

 

Ooooooooooooo!

Pizza and beer, when is the get together?

 

Saturday...my house...what do you guys want to take apart?

 

Ill ship over my 348 so you guys can do the engine out major for me!

 

550 gearbox...

 

LOL!

 

If this is on, I'd be down for tearing apart whatever and picking up some chow and beverages... any opportunity to learn a bit more about these cars from guys that have "been there and done that."

 

Stay tuned. Jet-X might be up this saturday and we may break something on his 456. It you want to take something off your car I am sure we can arrange it. Bring a creditcard in case you need to stay overnight at the Holiday inn especially if Ernie helps. I have a race on the 24th and need to do a few things to my Z06 racecar.

Dave...that was funny! Thankfully I have never seen the inside of a 550 gearbox. I have owned this car for about 3 months and it is absolutely boring...no drama. I am not sure how much I will ever get to learn about the 550 since it appears that there will be little on the job training. But that's a good thing. On my Z06 racecar I have changed oil about 6 times and changed tires about 6 times, changed brakepads twice. How nice to have "no" mechanical experiance with these cars because nothing breaks.

 

I can just send my clutch so that we can put an end to this whole thread if that would help...

 

I've been able to pull that stunt on my own, lol!

Nah, this is just starting to get interesting - spec for your set-up-height is 47 - 51mm. What did your mechanic say - enough material left to machine it?

 

Sure send it FEDEX 2 day and we will have at it by saturday. I think I even still have a 1/2 can of Kluber grease around here somewhere. It is really not a big deal if the plates are serviceable and we can get the dolts at Friction materials to use their calipers properly.

 

Oh!

You'll get yours lardass.

But that was pretty funny. LOL!

 

Well, I replaced the clutch last time.

Some of you may have read my other update but I shipped the car up north and the car is now bucking violently when I try to start moving in 1st. Took it to a shop yesterday that recommended I replace the clutch. I'd like to just have it resurfaced since its new-ish.

I've called two 'clutch shops' and neither of them knew what I was talking about when I asked if they could 'resurface it'. Can someone dumb down an explanation for me to tell them what I'm looking for? One of them said, 'oh you mean rebuild it? I have to see it...'

Thanks

 

Drew,

What is your status?

What exactly was done to your car?

What exactly was done to the clutch?

What status of throwout bearing?

Flywheel pack greased?

Who did the work? FNA shop? Indy shop in business how long?

 

Thank you!

independent did the last clutch. Drove it for at least 3 months since then as a daily driver, no problems. Throw out bearing was not replaced then and the flywheel looked fine.

Had it shipped up to MA from FL. Transporter took 4 extra days, no doubt dropping off/picking up other cars. I show up to where he is and the car is already off the truck so i didn't get to see him drive it. I get in the car after he leaves and drive away. Get to a stop sign at a little incline and put it in first, the car bucks violently as I try to pull away. I find that riding the clutch with high RPM's gets it to engage without bucking. Smells nasty. It feels like you're at a dead stop and you're trying to start in 2nd or 3rd.

Took it to a shop yesterday and they drove it and looked at a couple things from under the car without removing the pumpkin. Said they believed he warped the disks and I have to replace the clutch.

Car is in a garage here in MA. I can drive it by either riding the clutch at a dead stop or slightly engaging 1st to get it moving (sometimes with the buck) and then quickly dropping it into 1st. Shifts smoothly on the highway once moving. Whats odd is the other morning when I got into it, it seemed to drive fine at first (when cold).
