It was with some hesitation I started restoring the power steering, but thanks to all that have contributed with info and photos. It took me somewhat less than 6 hours changing hoses, and overhauling the control valve assy and the power piston. This is how I did it.
1. car on hoist remove LF wheel.
2. remove Pitman arm with tool W 142 but used a shorter bolt, approx 2", otherwise you hit the freeze plug.
3. removed steering reach rod from bellcrank.
4. removed hoses from power piston, put a tag on the old hose so you know which one goes upper/ lower on the piston. removed hoses from power sttering reservoir and pump.
5. unfasten clips holding hoses to frame, but let them stay in place on hoses.
6. let the control valve assy with all hoses in place slide downwards to the floor. It's handy to have a helper on a ladder guiding the hoses downwards while they descend.
7. remove power piston from bellcrank, tool W80557.
8. remove power piston from bracket on frame.
9. remove hoses from control valve assy, and lay them out on a clean floor.
10. overhauled the power piston and the control valve assy.
11. install all four hoses on the control valve assy.
12. connect steering reach rod to bellcrank, dustboot DOR 13561, while some one holds the control valve assy so it won't fall to the floor.
13. reinstall power piston to bellcrank and to frame.
14. reinstall both hoses to power piston.
15. transfer clips from old hoses and install on frame.
16 guide two remaining hoses upwards and connect to reservoir and pump.
Start the engine, with wheels touching the ground, turn left and right, refill Dexron III, start engine, turn left and right. No more air to bleed.
All in all, 6 hours, all parts came from SI and out of 8 fittings on the hoses I only had to bend, slightly, one fitting. And it really pays off to remove it all.
