First of all go buy a splitting tool, it make life much easier... split it on its side with one side facing down so when it comes apart your transmission stays in place... Done a few motors and its no big deal just take your time and dont use a pry bar... aluminum breaks!!!!!!!!!!

So true, the case spitting tool makes things much easier. They are expensive though, I priced one for my CR 500 motor, and the thing was like $180 if I remember correctly. I just made my own, I make alot of my own specialty tools. Here is the one I made, alot of money can be saved with a welder and cutting tools.

Also, be careful with the tranny, you don't want the gears coming off the shafts, it is a real pain to figure out what goes where if things come apart. I have learned that one the hard way.
