Here is part of a draft I’m working on. As you can see, it still needs work.

An important feature is a “dam seal” should not tough the input shaft. It should be slightly toward the clutch from the ground input shaft seal surface. Test fit the disc on the input shaft and make sure the splined hub can’t touch the dam seal.


4)There is the later 915 seal used with the removable guide tube with the O-ring.
The input shaft seal is 999.113.327.40 and is 23x35x8/11 mm size.
The O-ring is 999. is 43x1.5 size.

To remove the tube (and seal) it takes a 5 mm steel loop to grab the tube. The Factory recommended a loop that seems to be about 3 mm. Occasionally it takes a lot of force to pull the guide tube. Some light lateral tapping helps.

Installation uses P381 to install the seal in the clutch release bearing guide tube. Then protection guide tube P382 is installed over the input shaft and use a pipe tool (40+ mm OD, 26.7+ mm ID) to install the assembled part in the transmission.

The “dam seal” is 36x22x6 mm. There is a CR 8690 that is 1.437”x0.875. I haven't test-fit yet.
To install a dam seal the tool “of local manufacture” measures:
