Transmission front drive shaft seal "spacer"
« on: March 12, 2019, 08:32:30 PM »
I am needing to replace the transmission front drive shaft seal on my M3 Half Track. The seal that is in it has AT 1805X128 stamped on it. It is a leather seal, so I assume it is a Chicago Rawhide seal, for which I can not find any info on. i found postings on this website that says a National 410316 will work based on dimension in the manual, but has not been verified. This site also listed SKF 22446 as the seal. Anyone know which seal to use?
Also, there appears to be some sort of fiber spacer that is behind the seal, which parts of which have been chipped off. Anyone know where to get one of these or what can be used as a substitute?  Does it even show up in the parts diagram?  It may be something someone else added to get the seal to ride on a different part of the drive shaft yoke.

I rebuilt my trans/tcase and there was no spacer behind the seal in mine. I see no reference to a spacer behind the seal.  There are shims between the case and the seal housing.
