Early D17 power steering

My bad, didn't see Ricky Ky's thread until now. Kind of same thing. Darrel

Narrow front or wide front?? If a wide front, he should make sure the swing arm that the tie rods connect to underneath is free and not dragging on the front axle. If it seems to "power steer" to the right and hard back to the left, the steering rack pin has sheared off inside the front support. If both of these things are OK, I would yank off the pump and tear it down. There could be a woodruff key sheared off on the pump gears, which would allow it to make oil flow, but freely flow and never build any PRESSURE, which is required for power steering. If he wants to somehow get a 2,000 psi gauge plumbed into the pressure line from the pump to the steering control valve, that would be best to verify things, but I can have a pump off and stripped down in 60 minutes and it would take longer than that to make a pressure gauge capable test line.

The rack must be "timed" when reassembling so it steers equal distances full right and full left.

I rebuilt the PS in my narrow front. New seals in the bolster, new gears, seals, pins in the PS pump. If it’s an early model driving off the generator make sure the output drive of the generator is in good shape as well as the pump. The connecting collar between the two is an issue. Over time they slip when worn. The collar/coupler is a shocking $95 part but it’s required if you want the PS to perform correctly. This will cause the issue he is having. That would be the first thing I would look for. Not that hard of a job to separate and inspect. My PS works well after I rebuilt it, just wear parts in these 60 plus year old girls starting to go bad.
