I think if you just start pulling off the damaged stuff you may well find the tri flange is not damaged. In fact the damage looks pretty minimal to me. Get all that frayed flex disc out of there and it will look a lot better.

The three fasteners for the flex disc are just through bolts and not at all special.

you likely have the slotted nut, you can put two common screwdrivers together with a hoseclamp, and pry on them. or use the screwdriver/hammer method to remove the nut. you will need a new nut, and it's going to be a 30mm 12point head.

Any update on this? I've had the same issue and am looking for safe ways to remove the nut.

Anthing that was bent should be replaced.

Somepeople had the special Sockets for that slotted Nuts in the Tool Rental, I have not paid attention to which ones are which.

PM Stretch for details on this: In another forum I believe He said that the Replcement Nuts are 12 Point and use a regular Socket. He said it is possible to use a Punch and knock and loosen the Slotted Nut and then replace that Nut with the New 12 Point Nut and avoid buying the special Socket.
I think that may or may not work.

If you are going to use the Punch method I would be sure that you have a source of the 12 point replacement nut first.

Thank you, the 12 point replacement nut is the last thing I need to make this come together.

I appreciate your research and advise.

Think you've seen it all? How's this for a flex disk disaster:

Now thats friggin interesting. After doing the 5spd swap the no name brand flex disk I installed lasted 14,500 miles before it started making a ticking sound. There was no vibration, just very light metalic tick tick tick under hard acceleration. I replaced it promptly with Lemforder/SGF part. Keep in mind that I'm using smaller flex disks than what came originally on the 300D turbo.

Did you notice that car was only 6ish years old but had 202k miles on it already? That's well over 30k a year....sounds like they did not maintain the car properly. That flex disc's rubber looked very dry and baked like it spend a lot of time in a really hot/dry climate. Not surprising it failed under those circumstances.

I've hit a snag here, I never altered the nut to loosen the front of the driveshaft when I removed the flex disk. Now it seems as if there is tons of room between the transmission yolk and the flexdisk.

I must be missing something?

Could the centering bushing also be shot? Thank you for all your help.

I should also add, I am able to slide the front portion of the driveshaft in and out a small amount, just enough to be able to get it on the transmission. Thank you again.
