Testing steering pump on D17 steering problem

agman · Sep 12, 2017

Have lost power steering on D17 Series IV, with cylinder and valve integrated into gearbox. Was wanting a way to test the pump before tearing the gearbox apart. Small gear pump that is belt drive off the crank. If I pull the hoses off it rotates freely and put a finger over the inlet and outlet and feel pressure when the shaft is rotated. How can I make sure the pump is fully functional? Are these supposed to be primed when setup or do they self prime. Did not seem like much oil in the suction line and didn't hear the typical whine of the ps pump. Wheels just flop back and forth and steers easy to the right, but have to twist the heck out of it to get it to steer left. Any ideas?

If it steers easy one way, doubt it is your pump. Maybe the control valve.

Darn- wish my D-17 had P Steering! Its a pain both ways! He is probably right in the valve- but I would also jack up the front end- off the ground- and then turn both ways- see the difference. Also check ball-joints and any parts that could be froze-up. I have seen cylinders "go bad" that have done this.
