Front Cover - OIL seal installation question

[Onefast99gsx]

Not a great pic but here is a pic of the underside of the oil seal. You see where it's open. Under the inner lip is a little spring that goes all the way around the circumfrence. The outter lip is what is butting up against that little ledge I was talking about. When the oil seal is pushed into the front cover with a socket, it's not sticking up at all. It sits just below the aluminum surface. I'm putting it in the right way, I was just wondering about how far it was supposed to go down.

I examined the book this morning and looked at the CAD print. It does look like they are showing the open space in there. It's not much, maybe 1/16+" I want to say it's suppose to bottom out at that little raised edge that you can see in my first pics.

Thanks.
