Flex disk installation
1981 300CD I have searched this forum and looked in the service manual but cannot find the answer I seek. Should the flex disks have a small space between the rubber and the flange at the bolts? There is a metal to metal contact there, but the rubber does not meet the flange. Is this correct? The circular metal tube that is part of the flex disk at each bolt hole that the bolts go through holds the flex disk about 1/8" away from the flange. Unfortunately I did not see the flex disks before they were removed from the propeller shaft and the drawings in the shop manual are not taken at angles that show me that.
Can it be that those tube ends are supposed to seat in the flangesand haven't? Can it be that we are installing the wrong flex disks?

the flex disc sounds fine, but I think there is a front and back to that flex disc. Make sure you get that right. I cant recall at this moment.

Dowel tubes
-------------------------------------------------------------------------------- The dowel tubes mount into differential flange and transmission out put flange. ---------------------------------------------------------------------------------------------------------------------------------------------------- This is what my question is about. Do the dowel tubes seat into the flanges far enough that the rubber part of the flex disks are against the flanges or is there a 2mm 0r 3mm space between the rubber part of the flex disks and the flanges?

That is what I needed to know. There is a gap, though I have not measured it. I was only guessing. The gap appears to be even. Thanks for everyones input.
