Well if you can reach the Lovejoy coupling, try moving it some by hand
while you put your finger over one of the supply or discharge ports.
Usually they seal well enough you can feel some pressure or suction at
the port. Once you know which way it has to turn, reconnect the lines
and bump it over with a quick on off while someone holds a piece of
paper or cardboard against the coupling to see which way it's turning.
Assuming this is a three phase motor, and if the pump design prohibits
any reverse motion at all, (not likely), borrow or buy a motor phase
checker. Grainger used to sell them, maybe they still do. It connects
to the motor leads allows rotation pre checking without actually
running the motor.

Awl--

Ahm about to hook up a very bad-assed Kalamazoo automatic horz'l cutoff saw.
Ahm doin my best not to burn it up/down (which would make *three* in a
goddamm row...), but I don't have a way of predetermining rotation on the
pump.
The saw motor used to be a "reference", but numbers came off the wiring, and
that reference is lost. IOW, even if the saw motor spins right, the pump
could still spin wrong.

How bad is that to do, momentarily? Can I get away with it, ie verify pump
direction w/ the pressure gauge?

As a pita alternative, I could disconnect the lovejoy coupling, and look at
just the motor spinning, IF I knew what direction the pump head should turn.
I looked for the arrow on the head, but did not see it. I know the high and
low side of the pump head--is there a std rotation direction between the
two?

Iny idears??

I'm tryna get this thing going *tonite*, as I got some peeps comin over
tomorrow, who I would like to see turn green w/ envy....
