Thanks, that clearly and exactly answers my question. They are bolts
so I'm going to have to get enough clearance to pull them out.
Everything is so closely coupled here that I think they must have put
the shaft into the coupling after making it up or slid the engine back
and forth on the mounts. The only way I can get enough clearance to
undo this is to cut out the stuffing box hose and slide the stuffing
box back. Then, I'll really be committed to the project.
