BTW Vance should be working on that pump dyno by now :)

Paul, and others. I am finally winding down from 200% activity,
leading up to the Camarillo air show/fky in. (We had well over
10,000 attendees - about 8,000 paid adult admissions at the
gate), down to a mere 150%. So perhaps I can show some progress.
The pix shows a mock up of the drive, utilizing the horizontal shaft
mounting base I fabricated. The torque cradle for the motor is
still in work. I think I have to reverse rotation on the motor,
what is the proper direction on the pump? it is not as obvious
from the housing exterior as most pumps, and I do not want
to break the sealing - I would assume it is clocwise looking
at the pulley, as that is usual for belt drive auto accessaries.

pix ?

Looking at it from the pulley side it is indeed clockwise.

I think you will need two belts to transfer the required HP Vance.
What pump RPM does the current ratio work out too?

The nominal ratio is 5 inch on the motor at 3450 advertized
to 3 1/2 on the pump for about 4930 , with Vee belts it is a bit
vague as to the working radius.
I will try the single belt first, with the full wrap I think the
power can be transmitted - if not -- will modify
The single belt was OK for some pretty heavy panel "raising"
but we shall see.
The motor does not appear to be designed for rotation
change, so I will have to mount it "off side" on a wider base
