Yes, it will come out! And, before you remove the drive plate from the end of the crank-shaft, carefully measure the distance from the mounting flange on the bottom of the engine block, to the lower face of the drive plate and install the adapter so that the plate will have the same measurement. Another way to say it is: From the top of the place where the engine sits, to the bottom face of the drive disc. It is much easier to do it the first way, with the engine off the machine! This from a long time owner of those machines, Rusty Jones

Thanks Rusty...
I was hoping that it would--I didn't look forward to busting knuckles trying to loosen those allen screws! I was wondering about that measurement too--thanks for clearing it up for me.
