Trying to set damper plate installed distance. the car is a 94 968 with auto trans. Have found to get anywhere near the correct adjustment I have to remove the bolt from the rear torque converter flange hub and move the center shaft back. when you do this and set the damper then the lock bolt doesn't line up with the notch in the rear. Has anyone had this delemma and if so what was the fix

First off welcome to the forum.

As for your question I haven't had to replace mine yet so I don't have working experience with it but it sounds (as you seem to know) like an alignment issue. If moving the tube around isn't working try to loosen the trans, I would think it should have "some" adjustment in the mounts. I'll look over the manual and and if any thing jumps out I'll post it here.

I could not find any info on the damper install/adjust in the 968 manual but did in the 944 (you really need both 944+968 as allot is not moved over to the 968 manual, get them here http://www.cannell.co.uk/Manuals.htm).

Ad libbed from the 944 manual:

With a straight edge across the engine (over the damper) it should measure 18mm +/-1.2mm from the flat part of the large center flange to the straight edge. Adjustment is made by adding/removing shims on the back side of the damper.



I had a thought, are you sure the torque converter is seated all the way? While turning it by hand lift and wiggle it, it will clunk when it seats. You should not be able to get you fingers behind it, if you can then it's not seated.



Hope this helps.

Thanks for the feed back. The engine and the transmission are out of the car. I have talked to my local porsche parts guy as well as tried to find as much as I could on the internet. The damper plate can be adjusted to spec, but to do it the rear clamp and bolt have to be removed from the torque converter drive hub. When you adjust the damper, even to the smallest shim, the bolt on the rear hub no longer lines up with the hub and the alignment groove in the shaft. I got this car because the damper was not set correctly and it pushed the flywheel into the engine and destroyed the block. I have found that the part numbers for the torque convert hub are different for the 944 and 968, I cannot find anyone who knows the differance, was thinking that possibly the parts were swapped by the owner before me and that created the problem Thanks for all your help Joe D

Joe,



Welcome as well. I can't help with your question, but my car is a tiptronic and had the "rubber buffer plate" replaced on 2005 by a shop in San Diego. Not sure if the folks there might be able to help.
