I have a 2008 2500 heavy duty Dodge Ram with the 6.7 liter Cummings Diesel and the G56 6 speed manual transmission I bought the car about two years ago over the previous 18 months since I bought it I have had to put 3 clutches in it this last time when the clutch failed it was a dramatic failure and caused $14,000 worth of damage bellhousing bolts cracked transmission casing crack transportation as well as wines and other problem is there anyone that can tell me whether or not Chrysler Corporation has had problems with this new clutch design utilizing a single flywheel clutch assembly bolted 2 and 8 inch thick peace of Steel they call a flexplate the second time I replaced the clutch assembly I also had to replace the flexplate as it totally disintegrated can anybody help me or tell me what to do to stop this problem and how I can get Chrysler to pay for it thank you Cowboy horse trainer
 
"Cummings" is a town in Georgia.
Your engine is a Cummins.

Sorry but I'm having problems understanding your post.
Where is this 8" thick piece of steel?
You write about a clutch and then mention a flex plate. FP are in auto trucks.
 
There is a plate that the DMF bolts to, but 8" is weird. That should have been replaced with a SMF, so if your tearing up clutches that fast, it's either your mechanic or manufacture of your clutch. $14,000.00 is also a high cost, you can get a G56 for $5K and SMF with clutch for @ $500.00. Also I'm not aware of a change to a SMF. And yes it's a problematic but not what you describe. Their noisy with a SMF conversion, run hot, and lots of DMF failures.
 
The original DMF (Dual Mass Flywheel) used a drive plate that bolts to the crank, then the DMF bolts to that plate. It is similar to a flex plate but w/o a ring gear. The drive plate is just under 1/4" thick and its about 13 3/8" on the OD. I measured it. IF the eight 10mm bolts that hold the DMF onto it were any part of the failure then those bolts were not properly torqued. When those loosen up they tear up the holes in the drive plate and then the bolts heads tear into the engine to trans adaptor plate, the bolts can break off in the back of the DMF. None of this is good news.

Pic's can help and I wouldn't expect much from Dodge if they didn't install the parts.

3 clutches in 18 months? Either they were all installed with a time bomb in them or we have to look at driving conditions. But knowing anything about the nature of the failed clutches is really important, same mode each time or unique each time.

Good luck.

I highly recommend South Bend Clutch in your situation, but if your running stock, or close to stock power, go with a single disk, in a Single Mass Flywheel. Stay away from the dual disks unless you need the extra pressure due to your application. If you call SBC, they'll go over your application and give you an honest evaluation, and they won't try to sell you something you don't need to pad their profits. I've talked face to face with Peter from SBC, he's a strait talking gentelman, and knows his business well. There has been situations that they covered the warranty, even when it wasn't their fault. And if you have paid someone for your clutch jobs, DO NOT GO BACK THERE.


Good luck
Steve
