Does anyone have a link to an exploded view of the power steering pump on a 95 Ranger 2.3L? I removed the pump and the large fitting came out of the pump instead of the smaller fitting with the hose. A spring and a plunger fell out into my trash can and I want to make sure I got all the parts. I have the spring and a plunger and I am worried where is a check ball deep in the trash can. I have had a leak for a while and I just figured out it is from a cracked reservoir. I plan on putting a new reservoir on it and putting it back on. Yeah I can get a crap Chinese made one for $50 and have to deal with this again in a few months when it dies. I am finding worn out OEM is better than new aftermarket junk. With luck a diagram will come with the rebuild kit.
The 97 shop manual has zero detail, indicated by this instruction:
"The replacement pump..."
The pumps I have messed with have had a brass spring loaded thing that was retained by the fitting. There was no check ball loose that I remember. Just the brass slug-looking thing and a spring.
Ford previously sold re-seal kits that had all the seals and O-rings needed to re-seal a pump.
Do note that the line (high side) screws into the side of the pump, through the reservoir fitting(which retains the reservoir) into the pump body. It does NOT stay solid in one place, and can move. That is normal, even with the line fitting tightened in place to the pump fitting.
Now that I think a bit, the spring and slug are the relief valve, if memory serves. If the pressure in the line goes high enough, the fluid will move the brass thing away from the fitting, and allow the fluid to flow back into the reservoir. The spring is the relief valve 'setting', I guess. It has been years since I took one apart, but do remember needing to compress stuff in place against a spring disk, maybe, at the back of the pump body, internally. If you take the pump apart to install new seals, do not loosen the pump fasteners all the way, do a partial turn on each, and repeat, slowly releasing the spring pressure. Again, if memory serves me up the proper data.
