I have 2 O rings that fit over the nose of the crankshaft behind the front seal. I see no purpose of this o ring as it just sits at the front of the crank shaft. What is it supposed to seal?

This O ring is critical. Without it oil will wick between the morse taper of the crankshaft and the crank hub. This results in oil being slung about in most cases.
You can't skip installing it. |
