I did quite a bit of searching on this topic and felt that it would be best to continue this thread compared to others and compared to creating another one. I'm rebuilding my power steering control valve and piston assembly. I have my original (which was fairly good, thankfully) as well as 6 donors that I picked up under various circumstances. I used the control valve spool assembly from a donor because mine had two very small nicks.
I used rebuild kits (more than one) from NPD. I also had an NOS Ford kit C6OZ-3C651-A for the piston.
I used the Evaporust method to clean, as well as the gun blue for refinishing mentioned in this thread.
I'm down to three questions.
1. The NPD crimp clamp shown in the first picture is far too wide to put on the original end bell boot. The picture shows the new compared to an original. I tried using two different very nice originals but as soon as I went to pinch them down they snapped. Where do I get a correct sized and looking clamp?
2. For the worm gear clamp on the larger end of the piston bellows dust shield, my collection had various makes/models, so I can't say what would be original. Any recommendations, pictures, etc?
3. For the crimp clamp on the smaller end of the piston bellows dust shield, multiple originals had a very unique style crimp. Something like a diamond for lack of a better term. See picture #2. Any tricks to duplicating this?
4. The last picture shows the Ford kit NOS crimp clamp discussed in question #3. Is this correct? If not, what do I need?
Other notes - the NPD end bell boot was not accurate. I was able to use an original. The NPD rubber shroud seal and sheet metal retainer was inaccurate. I had to use new rubber - old ones were too brittle, but I was able to use an original retainer.
Thanks, John
