66 power steering

[Lars Kneller 8246]

My power steering is not working. I replaced the pump with a rebuilt one, and it still doesn't work. Do I assume I need a rebuilt steering box? Thanks!

That’s all that’s left

So, you have zero assist and have to muscle the steering wheel around? Did you bleed the system after the new pump install; front wheels off the ground and lock to lock?

That is correct, and I did not bleed the system, so will do that next, and keep you posted. Thanks.

Hello Lars,

Just a point of clarification.  With the front wheels off the ground, you may have to turn the wheels lock to lock 20 to 50 times.  This should be done with the engine OFF.  Once there are no traces of bubbles in the reservoir, lower the car, start the engine, turn the wheels lock to lock a few times (do not hold the wheels in the locked position).  Check for satisfactory operation.

It is possible that the rebuilt pump failed out of the box.  Was your steering working before replacement of the pump?  Hydraulic failure of the steering gearbox would most likely be due to internal seal failure.  Broken parts in the gearbox would be very unlikely, especially if you can steer the car manually.

I rebuilt the pump and steering gearbox on my '67.  If you want to see what I did, see here:

Also check your hoses. Had a clog in my pressure hose. Chased my tail trying to figure it out until I stumbled on the hose (which was brand new) by accident.
