Np208 oil seal

[Gussie]

Hello gang;
I'm rebuilding my np208 and when removing the oil seal for the transmission to transfer case I had two 19236 oil seals in there. Is this factory? Should this just be one thicker oil seal?
Thanks

Putting them back to back keeps the fluids in the trans & case separated. The factory seals are usually a double or 2-way style. Back to back works fine tho.

Hello, another question on this np208. There are 3 washers/rings?..on the shaft but I didn't see how these were spaced before the needle bearings spilled out. Is there a spacing to these 3 rings or do they all stack up on the end near that sprocket, thanks
