Cranking and not firing up?

Marty,

That would be me. I've removed and replace the coupling/shaft too many times and I hated it every time. Never had a problem before but, there is always a first time. I see setscrews in...

Regarding setscrews: I don't have any coupling to shaft set screws. The shaft is a "press" fit into the coupling. There is one "setscrew" in the coupling that holds the keyway in place. A...
