I've begun compiling a parts list for my truck. I will go ahead and replace the flywheel, clutch, pressure plate, release bearing and possibly the clutch pedal (damn squeak). If you guys can list the part numbers it would be appreciated. So far I have the follwoing numbers:

Flywheel 24232434
Flywheel Bolts 97226124
Clutch 12582860
Pressure Plate ???
Release Bearing ????

Update: Called the dealership this morning. They are willing to look at it tomorrow. I'm trying to talk them into covering this issue under warranty. The truck has 107k. I found a flywheel from Carolina Clutch for $250 and a clutch kit (pressure plate, release bearing & clutch) from dialaclutch for $465. Alldata is showing me about 7 hours labor.

Well if it was me and I was going to put the dual mass back in I would "make sure" it was the latest greatest GM flywheel. The clutch and pressure plate is a different issue IMO. I don't think the GM c/p is all that great and you can buy better for the same money or less. A few guys are saying South bend has a setup that will hold considerably more than stock and no more money than a stock setup. If the dealership will replace the flywheel n/c I would replace the clutch/pressure plate at the same time. It will never be cheaper to do the clutch replacement than when they have the tranny out anyways.

I'm definitely ordering the flywheel from gm with the above part number. I can get it for $287. All parts will be about $700: Flywheel, clutch, pressure plate, release bearing and bolts. Hopefully the dealership will work with me.

Not sure which bearing you mean by release bearing but make sure you do the Pilot Bearings and the Throw Out bearing. Since you have the tranny out do all moving parts to eliminate later failures. OEM version 2 of the flywheel isn't holding up any better than the last one I had in, I have about 20K on it and it is starting to fall apart. This is my 3rd OEM flywheel and will definately be going aftermarket next time.

I know one guy who is running the new GM flywheel and SBC clutch and pressure plate and he has dynoed at 475 RWH and 976 RWTQ with no noise and/ or slippage.
That is what I am going with so I hope that it works.

Where can I get the SBC clutch setup? I took the truck to the dealership today. They confirmed the issue. I had to call GM and setup a file. They are calling me back Friday to see if they will cover it.

here is the web page, get the phone # and talk to Peter.

Mine was at the dealer last weak but they would not put in a SBC, but coalbucket is running one with no problems.

If you cannot get the dealer to du this under warranty, go to a non-dealer shop or do the install yourself. If you got normal tools, a hydraulic jack, couple jackstands and a buddy to help you you can do it yourself in one day. If you have questions PM me and I can give some advice. Also, search the zf6 forum for a thread I started about the install of a CPMac dual disc clutch kit. I posted some pics AND some copies of how to take out a tranny from the GM service manual. You should be able to print and read them. good luck.

If they do not cover I have a friend who owns a shop and he will do it for me for a nominal fee. I'm crossing my fingers. I find out tomorrow afternoon.

I just ordered the parts. GM refused to cover it in any way. A pretty ****ty way to treat someone who has owned 3 new GM vehicles. Although, I really enjoy the truck, it will be my last GM product. Below is a list of parts I ordered:

Flywheel #: 24232434 $287.57
Bolts #: 97226124
Pressure Plate #: 12582859 $206.12
Release Fork Bearing: # 88934649 $27.14
Pilot Bearing #: 12557583 $6.76
Clutch #: 12582860 $100.67
Clutch Pedal #: 15120866 $ 69.66

Oh yeah... just ordered 4 shocks from Kennedy... another $260.
..almost forgot the 4 new BFG AT's 285's (will probably mount them tomorrow).......

Did you have to remore that torsion bars and support to get the trans slid back or is there room to take the t case and trans. apart and slid the trans. back? I think that I am in the same boat as BADDMAX in the fact that I cannot get the local chevy dealer to warrenty my flywheel. even though it was replaced once at 30,000 and its bad again at 65,000. I think that the DMF is what is bad but I am not hearing all the raddleing that i heard alot of ya'll are talking about just under heavy load or acceleration it has a "spring" sounding raddle to it.http://www.dieselplace.com/forum/images/smilies/think.gif Also do you think that it is nessary to replace all the things that BADDMAX is replaceing????? Info is very very helpful.

Thanks

What did the stealer state as their reason for not covering?
So you went with all OEM parts?? Why the clutch pedal? Let me know how is goes, I'm probably the next member in this forum for this!! Let us know how it goes...good luck! I do know on my last clutch install at the stealer they told me they almost had to torch the flywheel bolts off as apparently the thing twisted like 1 or 2 degrees and gave them hell to get it off.

I have 107k on the truck (the reason GM denied me! I only had 100k in March!). I figure if the tranny has to come down.. why not replace all of the parts. I am replacing my clutch pedal (was replaced under warranty @ 30k) because it is squeaking again and hopefully the new part number will not make any noise. I've ran about 60k with the predator @ 40HP with no slipping. Other than the f#%@king flywheel the stock parts have held up fine.

I have 56K on mine and I probably have the stealer install one more so I have a good back-up during the testing of the SD kit. The prices are not too bad for OEM stuff, usually the rape you like an ape!!!

You need to check this and the link in it: http://dieselplace.com/forum/showthread.php?t=25875&highlight=dual+disc

You do not need all the parts 1badmax got unless you know they failed. I only replaced the flywheel, clutch, and pressure plate.

You need to be carful about two things: 1) when you release the hydraulic line from the master cylinder MAKE SURE YOU DO NOT PUSH THE CLUTCH PEDAL UNTIL IT IS HOOKED UP AGAIN. If you do you will blow the master cyninder off the firewall. 2) Make double sure you rehook the hydraulic line properly. The little shine lock wire must be holding the line. Once you rehook it try to pull it out (leaving the lock wire in). If the line is not attached properly the first time you push the clutch pedal you will blow . . . .

The Tq bars do not need to be removed. Neither does the tranny. Just slide it back 8 inches. I did not remove the transfer case but I should have. Refitting the tranny was much harder because of the additional weight on one side. My truck has a 6" lift so it was easier to get under it but the process was a little different. When Craig came over he removed the transfer case when he did the check and it made moving the tranny easier and faster.

so how exactly are y'all able to talk the dealers into replacing your flywheel, clutch, and pressure plate? i have been to three different dealers and they all refused to do anything about the growling and slippage. i guess i am just looking for whatever "trick" or "key words" you guys are using to get this stuff fixed. Please help!

Same problem as you. Why I spent $$$$$$$$$$$$$ to get CPMac's kit. Now I can't get him to reply or do what he promises. I recommend tradin in for an allison.

Come on Deadeye...trade it in for an allison??? That is darn near blaspheme!!! Maybe Super Diesel will come up with a kit to get out of this jamb? $1500 to upgrade the clutch and flywheel vs. $4000 to upgrade the allison? We don't have it that bad.

MaxRock

Max;
at least the allison guys can find someone to provide the kit !!!!!!!! I am not involved in doin a kit for this w/ SD so I don't know much about it. What I do know is that developing a SMF is a complicated, time consuming activity and then the testing and redesign :eek:

Deadeye...we have to keep the faith. Sounds like Craig has a functioning system...just not able to support it for what ever reason. It can be done and I truly believe there will be a marked for it. I hope my DMF lasts long enough for SD or someone else to provide a good workable solution.

MaxRock

I believe you're right, MaxRock...You can replace the 6.5 dual-mass with a solid flywheel...Same is true for the 7.3 powerstroke as well...(these are readily available from almost every parts store) the key here is that these are just a replacement clutch and I doubt they hold much more power over stock...
I would imagine that when Super D and his trusty sidekick ):h Ibdmax"in get their kit done, it will be able to hold much more than the stock unit...

You know that almost every handshaker GM sold will require this update at some time in the truck's life. SD and 1bdmax'in have a captive audience...just waiting for the DMF to give up the ghost.

I pulled my 5er this weekend for the first time w/ the VA 0-70-110 HP box, I towed in the 70 HP mode, no problem with the clutch slipping. Everything went well until I got home. After manuvering the 5er into it's parking spot, the clutch pedal felt weird. Really soft on top and engaged real close to the floor. After driving the truck about 10 miles, everything went back to normal. What the Censored was that all about?

MaxRock

Got my parts yesterday. Opened up the boxes today and took some pictures. The pressure plate comes with a clutch. I guess I didn't need to order the clutch as a separate piece. Anyone need a stock duramax clutch?

Well I got most of the flywheel work done today. Apparently AllData lists the wrong throwout bearing part number. So I'm waiting on the new bearing. Everything went together smoothly until they tried the bearing. I've got some new pictures on the site.

Did you have to remove the ZF or were you able to slide it back to clear the clutch? Doesn't it suck when you want to finish a project and you find out someone sold you the wrong parts. That just Censored me off!

Good luck with the rest of the job.

MaxRock

They removed the transmission and transfer case.
