Good luck to ya on finding that needle in a hay stack. Better stay close by. If ND posts a supplier that actually has any left they will be gone before you can pick up the phone.

 

What 64 PS or 65 250 PS?

 

Bill, In my Light Truck facts it says no P/S as an option on F100-250 2WD till October...oct 65 Im assuming as 65 model year run ended in August. No P/S for 4WD at all...or for F350

I know P/S was used in big trucks well before 64 model year...talk about a hernia parking one of those loaded down w/o P/S !!!
As far as an accy add on...you are correct...BUT, also like you said...good luck finding parts....

Inre to post #10. I made no mention of P/S for 1965's because Ford didn't offer it...factory or dealer installed.

Did'ja look at the illustration in the '64/72 truck parts catalog (Section 36, Page 7) I referenced?

It's the illustration for the following:

C1TZ3A633A .. P/S Installation Kit-Dealer Installed / Fits: 1961/64 F100 292 2WD.

No P/S for 4WD's until 1973.

No P/S for F350's until 1969.
---------------------------
flipklos: The Power Assist P/S system used on 1958/64 F100 2WD's is very similar to what these cars used:

1953/64 full sized Fords / 1955/57 Thunderbird / 1962/71 Fairlane / 1963/70 Falcon / 1965/68 Mustang / 1967/68 Cougar / 1968/71 Torino/Montego / 1970/77 Maverick/Comet / 1975/80 Granada/Monarch.

With Power Assist P/S, the steering gearbox has nothing to do with it. Everything is controlled thru the steering linkage.

Two P/S hoses (pressure & return) run from the pump to the Control Valve which threads onto one end of the draglink.

Two short hoses feed from the Control Valve to the Ram Cylinder, which is mounted on the frame rail on one end, a ball stud on the other connects to the draglink.

If I knew how to scan and post pics from the parts catalog, I would. It's prolly easier to look at the system in one of the cars I referenced above.

 

I get what your saying ND. The signal for the valve is picked up from the pitman arm and transfered to the main circuit driving the ram in the direction of wheel travel. You said no one has these kits anymore and if they do theyll be gone in 10 seconds.... Ill let the concours nuts have them.
I like to use original parts but will upgrade if somthing else is available. PSS has that kit Ill use that. Thanks though.

 

ND: Maybe you know the answer. Do the Ram setups actually work? ie. make the steering easier (at low speeds). I've asked in posts before, but never gotten an answer other than that they usually leak.

 

There's nothing electrical at all about this system.

It's hydraulic and uses Type F A/T fluid.

The Pitman arm attaches to the draglink, as does the control valve and the cylinder.

This system was used from 1953 thru 1980 on FoMoCo vehicles, on 1951/56 Packards, 1952/57 Nashes & Hudsons, 1953/55 Kaisers, 1955/66 Studebakers, prolly other vehicles.

It worked just fine for its time, and is cheaper to fix than the integral P/S boxes.

 

You can use a hydraulic siginal to activate a valve. Called a pilot system. A low or zero boost pressure piston sliding can compress fluid partialy opening a "balanced valve" causing it to move te high pressure valve open. As it slides it allows a limited amount of fluid through to the ram causing it to push in the direction you want. The valve sliding against the limited opening alows a volume of fluid out of the oposing side. Once its alowed that volume out the presure builds limiting ram travel.

The signal is pure hydraulic.

 

My '64 F-250 has FACTORY power steering. It works great even at low speeds. Now, with all that being said, I want to get rid of mine simply because I prefer the manual steering in the old trucks. Take a look at this thread https://www.ford-trucks.com/forums/8...ring-help.html and my pics and if anybody's interested, hit me up! I'm going to start pulling it off my truck as soon as I have a decent offer.
