Hi Mark,
The "lip" of the seal always goes toward the side with fluid. Assuming
the fluid is inside the ZF case <wink> then the "face" of the seal
should be to the outside, toward the engine.

The theory is, as the fluid heats up and the air heats up inside the ZF,
it build a small amount of pressure. The pressure gets behind the lip of
the seal and helps push it against the rotating shaft, thereby giving it
a better "seal."

I hope that makes sense.

   What is the correct  orientation of the ZF input shaft seal face ?
   Towards the trans? I can kinda make that out on the schematic , I

   The one just removed was seal face towards engine which leaked a
   little. And I installed it 10 years ago, but can't remember why I
   chose that.

   Why can't I  find my ZF manual

   Thanks,

   Mark
