No problem man. Thank you for the info. I'm surprised the sprocket didn't come off. Any idea what's holding it on? You think it's just staying on because there really is no force pushing it in that "off" direction? The chain really only pulls on the side of the sprocket so it might be able to stay on. Depends how loose it is I guess.

Your probably looking at north of $2 grand for the preventative repair through the dealer, if they will even do it on your instruction.
Damn.

Each unit is about $305 so around $610 total for the parts. This does not include any gaskets or other things you may want to replace while you are in there.
