The 3ph will be inoperable with the knob turned the other way.

I bet you're not supposed to turn it with a hammer, are you.
Looks like mine may never have been turned in 20 years. It's going to take some work to free it, though it did move with some careful (read harder hits than I want to, but have to) taps with a hammer. Penetrating fluid will help. Of course I'll be careful, as I don't want to break the orange girl!
3ph ball ends drop about an inch or so every 20 mins-½ hour with no load at all on them. /forums/images/graemlins/confused.gif
