I'm sure these questions have been asked before, but need to make sure I get the answers I need. My saginaw box on the '72 is leaking and I want to replace the seals. I normally shop at O'Reilly and they showed two different upper and two different lower kits. Not being sure which ones were correct, i decided to wait and consult the experts!!

Also, I would like to get the straight story on the correct kind of fluid to run in the steering system.

Thanks a million! Again, I apologize if these questions are redundant!!

 

As ND says, a seal kit is a bandaid job. For a permanent fix, get a Redhead Steering box. You would be money ahead.

 

In that case of not knowing buy both sets an return the one you don't use if you can.
Many times a special ordered parts they'll only give you a credit and not cash back.

If the shaft has to much side movement it may not hold a seal and still leak. Also if seal area is warn a groove down into the shaft any..

Originally, Ford only offered a master seal kit (C5AZ-3C538-A), but in 1973, broke the kit up by offering an individual sector shaft and input shaft seal kits.

Both part numbers have since been updated.

D7AZ-3E501-A (replaced D3AZ-3E501-A & C5AZ-3C538-A) .. Sector Shaft Seal Kit / Available from Ford.

F3AZ-3E502-A (replaced D7AZ-3E502-A; D3AZ-3E502-A & C5AZ-3C538-A) .. Input Shaft Seal Kit / Available from Ford.

Applications: Myriad 1965/2002 Passenger Cars, 1969/91 F100/350's, 1973/91 Bronco's, 1975/91 Econolines with Ford/Saginaw P/S

 

Thanks, guys!! I'd love to do a new Redhead box, but I just can't swing it right now. I've looked (drooled) over their website a few times. Maybe some point in the future I can do that. I think my box will be ok for now. Hopefully my plan will work. THANKS AGAIN!!

 

Actually the D7AZ3E501A has been discontinued. It was a kit that included some "compression rings" and seals that worked with them with the intention of taking up sector shaft slop. I believe D7AZ3E501B may work in it's place put does not include the compression rings. I personally have never tried the D7AZ-B in place of the D7AZ-A.
Bill. For some reason my computer doesn't paste the DOES II screen (below) here as I see it. The D7AZ3E501A is J'd out.

I deleted your last sentence and all the following fall-der-all.

1973/79 light truck catalog 10/88 final edition (on microfiche) sez: D7AZ-3E501-A

I typed this number into FTE sponsor horizonpartsguy.com before typing post 4 .. the MSRP & discount prices come up, there's no mention of supersession or obsolete.

1973/79 car catalog 11/88 final edition says D7AZ-3E501-A thru 1977, 1978/79: D7AZ-3E501-B

1980/89 light truck catalog 3/94 final edition sez: D7AZ-3E501-B 1980/89 all except Aerostar.

It seems to me that A was replaced by B at some point, but I cannot find a reference.

D2D says inre to D7AZ-3E501-A .. no records available inre to being superceded, but that's nothing new for a part number this old.

No PDC has D7AZ-3E501-A .. but there are many that have D7AZ-3E501-B

I wonder what are the auto parts store applications are?

 

DOES II shows the "A" J'd out. AKA discontinued. Not replaced by the "B" kit. In trucks I've always gone by long shaft (3575) 79 and older Ford P/S boxes took the "A" kit with the compression rings and 80/ with the advent of the E0AZ3575A short shaft taking the "B" kit. I dunno if the long and short shafts are same O.D or not. So it could just be the short shaft car and truck boxes have no room for the compression rings.
One curious note, If Saginaw made the "Ford" boxes in the Bumps I wonder why in the 70's cars they were different. On the cars the top plate where the 3575 adjustment screw came through was held down by 2 bolts. If the same vehicle had a Saginaw that plate was held down by 4 bolts. Example. If someone wanted to buy a seal kit for a 76 Torino. Ford lists Saginaw or Ford boxes. I always asked 2 bolt cover or 4. Check out 73/79 car illustration section 35.1 pages 3 & 8.

 

As you know, there isn't a peep inre to Saginaw, FoMoCo just calls it Ford gear, but try telling that to a coupla hard nosed peeps here in FTE land.

We went around and around with me saying the catalog says nothing inre to Saginaw (owned by Gov't Motors for decades).

I finally gave up, calling it Ford/Saginaw [gear], no one has complained yet.

DOES II Direct Order Entry System II .. I remember the original, a cluck I worked with called it does .. as in deer.

Mr. Wilson it takes 2 sides of the counter for a parts dept to work. You can demand to have perfect vocabulary all day long but if the smuck doesn't come in calling it what he heard it called on the street and you get an understanding of what he wants and offer a part for sale you wont have a job. just sayin

That's always been part of our job John. Especially Front (retail) counter salesmen. But even Back (shop) counter guys also. It's not as bad now but used to be Ford was Horrible calling the same part different names between the parts computer(fische , and books) and the mechanics shop manuals. Usually the mechanic would call it what the parts man is reading since he knows what it is and what it does. Usually the parts man wouldn't. So it was easier on everybody concerned to go by the parts computor's nomenclature.

 

Looks like I might have been right Bill. Notice how all 4 parts that are in the "B" kit were included in the "A" kit. So the 3575 shafts have to be the same O.D. So a "B" kit can be installed in a Ford/Saginaw Bump steering box. But as you always say, resealing one of those boxes is only putting a band aid on the problem.

 

There are a number of generic terms many people use to describe a certain part of a vehicle and while they may not be Ford-specific terms, I think we all generally know what's being referenced, when certain terms are used.

A 'rag joint' is a good illustration of this. Ford called it a steering coupling.

Another example is the reference to a brake 'proportioning valve.' There are no purely proportioning valves on a Ford truck. If a truck does have a brake valve with proportioning, proportioning is not the only function of the valve --there are also other features included along with the proportioning feature.

There's also a large segment of the population that uses the term 'posi' when describing a differential that directs power to both rear wheels. 'Posi' is just short for the name Positraction, which is the trademarked name for a differential produced by General Motors Corporation (in the Mopar, Sure-Grip was the trademark name). In a Ford, the differential that directs power to both rear wheels would have been an Equalok or a Traction-Lok.

Obviously, you wouldn't find a posi in a Ford rear end but, I understand what a person is talking about when they use this term.
