Here are the Left/Right hoses from the steer orbitol.
Then we used a pair of bulkhead fittings to get thur the drop case mounts.
Then hosed from them to the cylinders. Not quite done as we need a little more hose and some fittings.
I also filled the hydro filters and and the hydros them selves as we will need to fire her up the verify the oil flow to the steering before final hookup.

Tried to fire with hydros hooked up and only LOTS of smoke.
Engine runs on it own just fine.
Determined that the 2 - 1 overdrive is to much load for the engine to get above crank speed and run on it's own. Was told this engine is governed at 1800 rpms. Well there I go not doing my home work and actually check this out.
Removed the drive shaft and the tach said 2500. At least I will be able to lower my over drive and try to fire again.
Does anyone know these fuel pumps and if the rpms are adjustable from the outside of the pump? I would like to bring it up to 3000 to keep the over drive as low as possible and maintain 3600 - 4000 rpm input to the Hydros.

Hey Ducky sorry too hear about the problem.I know this may seem far fetched but even at idle the diesel is only running maybe 1000 rpm so even at 2-1 it still should have no problem turning the hydros.Here's one question for you are both pumps put onto the trans the same way??? The pumps are interchangeable for LH & RH rotation.Maybe you have one running one way and the other running the other way.Seems to me that the hyds are working against itself.You have the pumps facing each other and running on the same shaft ,so your going to have one running CCW rotation and one running CW rotation in order to keep them from working against each other .Larry
This motor turns the opposite direction of the Onan so I left the front pump as is and change the rotation on the rear hydro.
I am going to drop the drive sprocket down from 41 to 30 tooth and leave to driven at 20 tooth. That will give me a final of 3750 rpms with the engine @ high idle.
One interesting thing is in the OEM application this engine had a centrifugal clutch on it so it started under no load all the time. I figured that this was to aid cool weather starting. Now I am starting to wonder.
