Re: Power steering seal ?
I changed this seal years ago on my pickup. It has the same saginaw gear on it. You'll need to get a repair manual that shows how to adjust the steering gear. After you remove the gear from the frame, there is a large lock ring that you remove. Next, you'll need to unthread the valve spool. This will require a spanner wrench. I made a tool to do this job. I had a 2-1/2" socket that I cut a peice of plexiglass into a hex shape to fit into it. Then I drilled two holes in the plexiglass and inserted some machine screws that fit the holes in the valve spool. This also let me use a torque wrench on it when reassembling it.
Be very carefull when unthreading the valve spool that while unthreading it, you keep pressure on the input shaft. If this shaft pulls back, all the recirulating balls fall to the bottom and you'll have to get farther into the gear than you want to. (Learned that one by accident. After I got it together, I had to take it back off for some reason and forgot to hold the shaft. All the balls went "plink, plink...")
Another option is to just replace the whole steering gear with one from a parts store. Last fall I replaced mine with one from a 70's camaro. The box is the stronger one with "76" cast on it. It was $115 for me.
