Yes I thought about that also, Execept instead of in the sense of
restricting I was thinking more in the way if increasing oil pressure by
decreasing the diameter of the hole.
But your right, I'll have to pick more brains as to why it has the play.
Is it supposed to be like that? Is something F'd up with the flange?
Tune in next week....

Yup that's exacly what I thought.
What I don't understand is that there is a lip on the inside of bore
that
the pin slides into, the pin has a lip on it also. When these lips meet
there is a gap between the top of the pin and the outside of the flange.
If the top of the pin was flush with the top of the hole then I can see
how
once put into the engine it wouldn't budge, but since there is a gap the
pin
has room to work it's way up and out until it hits the case. Granted a
new
pin is longer then mine now but why the lips? Cause if it is supposed to
be
flush with the case the lips wouldn't meet and there should be no reason
for
them to be there.

I don't believe that part is there to any way keep the flange and
bearing indexed. The interference fit does that. I think it's just a
restriction on the oil flow. As to why is is able to move, you'll have
to ask Luigi, but every one I have been in is the same.
