As has been said the coupler to shaft connection is the hardest part. If possible remove the coupler set screws and fill the holes with PB Blaster. Let sit for several hours, refill and tap the coupler/shaft z couple times with a hammer. Not hard, the vibrations help the PB do it's thing. If you have room, slide the shaft back and use a puller to get the coupler off the shaft. If no room use a socket, quarters, a large nut, what ever fits and try MS's method (it worked for me). Be very careful not to use too much force, the coupling flanges will bend. If it doesn't start to move, leave slight pressure on it and apply more PB and wait for a while.
