915 gearbox input shaft seal question
HI,
I'm lucky enough to have a 72 915 with the internal seal. I've installed a new seal from Pelican, but it seems too long & the lip of the seal is past the machined surface on the shaft. See photos - is the seal in backwards? Seems like the spring, etc. should be to the oil side (it matches the orientation shown in the Haynes manual). When the input shaft is fully inserted, the seal is well beyond even the radiused area & sits on the minor diameter of the shaft. Picture one is the sealing surface of the shaft sliding through. Picture two is fully inserted..... Did I get the wrong seal somehow? Thanks, Steve

strangely enough, for a '72, the seal goes the other way. lip out. you might want to search for the grady clay thread about using another seal as a dam on the outside of the 1st seal and having a drain hole between them.

Here's some (hopefully) interesting reading:
