Your dseries motor doesn't have a 1/2 shaft.

PS: just remove the pump and push the lines aside. You'll probably have to drain the system, but that will happen when you take the lines off of the pump

A/C: you can just unbolt the compressor from the engine and use some wire or something to hang it. You don't even have to remove the lines or purge the system at all. That's What I did the first time I swapped.
