Be sure to take lots of pics. I had Alpine send me a new nose cone a couple of months back, nd from what I saw, he shaft in the nose cone is geared and goes directly into the blower drive gears. The nose cone is lubed via atomization of the oil in the blower (no separate oil res. like in Dallas' link.) I don't see how there could be a coupler in there also. I didn't take the front of the blower off to see since the nose cone can be changed without draining the oil and I didn't want the hassle.

After the install I still had the chattering, just a little quieter and different pitch. Alpine has assured me, and others, that this is acceptable so I guess I'll keep on truckin' and see.
