I'm in the process of several mods to a 317. Among them is installing the 400 power steering system. I have it installed on the frame and connected to the hydraulics using the 400 N3 controls. No engine yet. That will be a Kohler Command 20 HP.
Just for test purposes, I have turned the Hydro input shaft with a drill motor which runs at approx. 700 RPM (nameplate) All the leaks have been taken care of using this method but it doesn't seem to produce a lot of assist effort to the steering. Never actually taken note of a 400 steering at idle speed, should I expect to see an appreciable amount of assist at that speed? I feel fairly confident I have bled the system adequately but intend to do it again after the engine is installed.
Any info from experienced owners would be appreciated. Thanks.
