bump anyone.[/b]
You need to crack the case. The shaft sits inside the crankcase parallel to the the crankshaft. At the front of the motor under the exhaust manifolds. You also need some sort of press to get the bearings off and on.

I don't know how you're approaching this... But don't do it from the 'top down'.

Take the motor out of the sled, turn it upside down and remove the bottom crank case half. It's a lot less work than from the top down in the sled.

:chug:

I don't think you can take the motor apart while it is in the sled. Aren't all the bolt heads for the case pointing down?

Yeah, you're right.

Could always flip the sled upside down, remove the bellypan and approach it from there. ;) :lol:

Question? How big of a deal is it to pull the motor out and get it back in positioned properly for belt alignment?[/b]
not a big deal if you have the right tool
