Chris, you responded to my question in the oliver forum a few days ago.  I'm still unsure what to do next. The engine is ready to come out, so I could hoist that, then work on the crankshaft.  But how do I get the engine and clutch separated from the shaft that goes to the transmission?

I thought that shaft maybe just has splines that will slip out of the clutch, but just barely taking the weight off with my hoist, I cannot move the engine forward with a pry (did not put a lot of pressure on). 

The PTO shaft is out.  Also the mechanical lift is off because I will replace that with a hydraulic unit at the end of this project.  The tractor has a belt pulley and I don't see how to move the clutch housing back, if I need to.  

Thanks for any help.  [/list][/i]
