I found a complete power steering system that had been on a 57 Plymouth Belvedere (we think) that I want to put on my 57 Suburban that has manual steering.

I'm assuming there won't be any monumental obstacles but my assumptions have been wrong before.

I'm wondering if anyone else on here has done that swap and can tell me how it went and maybe let me know if there's anything I need to prepare myself for.

Thanks,

Wayne

Check your part numbers on the setups. You should be fine.

So, much to my surprise, the column came right off. It didn't give me any trouble. So I blasted it and am priming it and painting. When I got the column off I noticed that there is an insulator.

Does anyone know where an insulator might be found?
Is it still available?

A while back someone tried to show me how to use the program to locate parts but I don't understand it. I'll try again but in the meantime...help me out again please.

Thanks,

Wayne

I follow that link and looked at it. It looks like it doesn't have the slot that mine has. Can anyone look at that and my picture to confirm if it's the right one...or the wrong one. If it's the right one I'd buy it right now, the sooner the better but it doesn't look like it could work for me.

Probably this thread. Finding your own part numbers and then looking for them on eBay or by Googling (both without the blank in the middle of the PN) can be fun.

I wouldn't use the original rubber insulator. I forget who makes these but nylon seem like it would be more durable over time.

The one I posted is shorter too. Not sure which cars that one fits. But my '57-'58 Chryslers and DeSotos use the longer one like this one.

Ok, I downloaded the parts catalog and could not find the isolator so, I don't know which one I need to order.

Perhaps because what you were looking for is called an "insulator"? (Sorry)

From Nathan's first link:

"Really nice reproduction of MoPar number 1319797, otherwise known as the power steering gear tube insulator for power steering equipped Plymouth, Dodge, 1955-1957 Chrysler and DeSoto 1955-1958, and Chrysler Imperial 1951-1956. The insulator goes inside the flange or "tube" and can really help out with sloppy steering. These pieces have been hard to come by for a long long time. If the rubber is gone on your car it can account for all kinds of steering problems, usually blamed on other more expensive parts!"

The trouble is you are going to need to know some info about the donor 57 Plymouth (VIN, Model, etc) because I think there are five PNs: *1319 797, 1733 778, 1822 668, 1733 769 and 1822 667, as shown below.

Nathan's first link, for the 1319 797:

https://www.ebay.com/itm/1955-1957-Plymouth-Chrysler-DeSoto-Dodge-Po...

Nathan's second link, for the 1822 668:

https://www.ebay.com/itm/1959-1966-Chrysler-Imperial-Power-Steering-...

Andy Bernbaum might have them as his "S-140" or "S-141"

Who is Nathon? Screen name "Powerflite"?

Part of the problem is that I don't know anyone by name here unless it's in their screen name. I saw the first link and it looks like the part I need... Then I saw the second link and it looks like the part I need... LOL I don't have the "tube" disassembled because until I have the part in hand I don't want to damage something that I don't know for sure that I can replace.

Then I downloaded the catalog but since I've never tried looking anything up in it before my eyes started crossing after 40 minutes of reading and trying to figure out what section I needed to be in. I found the steering column and I could see the tube but I didn't see the adjacent end of the shaft or the "insulator" between them in the diagram.

I can see, from the sheets you posted, that I would be needing the "insulator, tube" part number 1319 797. BUT, I don't know how you knew to arrive at that page. Again, I got to a diagram that I thought SHOULD have shown the part and it's number, but I was evidently not quite in the correct section.

I think I see what you did, I think you found the correct diagram and found the part number and then did a search for the part number. How did you arrive at knowing what the part number was?

The first and second link Nathan posted looked like the right part but I didn't know which I needed. I didn't see any part numbers in his reply or in the ebay ads.

I really appreciated him posting them, but until now I didn't know which was the one I needed.

I really want to be able to do that. So it looks to me like you looked at a diagram, found the part number and then plugged it into the search bar of the digital version of the catalog?

How did you know where in the catalog to look to find the diagram with the part numbers on it. Then you plugged it into the search bar right?

In the mean time it appears that I need to order the 1319 797?

Thanks so much, I just getting further and further lost the more information I got.
But I see what you did, I just don't know exactly how you did it. If you can help me a little more I think I might be able to navigate the catalog.

Thanks again,

Wayne

To be fair, I've had way more practice with the pdfs than you have so I can find things faster than you might right now. You'll get better the more you use it.

One thing that I feel bad/stupid about is I created an index for the pdf and posted it in a thread, but not the "How to" (use the pdf) thread. Very sorry about that to you and any one else.

I printed off the index and have it handy here at my desk. When look for something, I check the Index for the most likely Group I need to search on. Then I drag down to the pdf page at the start of the section (using the gray bar at the right side of the pdf screen), in this case, "Group 19 Steering" starting on page 573.

This index (right click copy the image and then save it somewhere and print it off and keep it handy to your computer):



First posted in this thread:

http://www.forwardlook.net/forums/forums/thread-view.asp?tid=72406&...

And now (just now) posted in the "How to use the pdf" thread. Sorry.

http://www.forwardlook.net/forums/forums/thread-view.asp?tid=66548&...

Okay back to your problem:

Once I dragged the pdf (using the grey bar on the right side of the pdf screen) down to page 573. Then I started paging down in the pdf (using the down arrow on the pdf screen), looking for your power steering mechanism and the coupling and the insulator (I had already looked at Powerflite's (Nathan's) links so I knew the name). I went through all the diagrams but DID NOT FIND the insulator (just like you said). So I went back to the 57-58 Coaxial Power Steering diagram (because I thought that that is what you have) and noted the section which had the coupling in it, i.e. 19-15-23. I figured that the insulator must be very close to the coupling in the listings. So I used Ctrl-F to pull up the pdf's search box and then typed 19-15-23 into the box and hit NEXT.

Turns out there are seven listings for 19-15-23. On the 4th click, I got the page with with the list for 19-15-23 "Coupling" (PN 1483 471 - not that we care). The good news was I saw above that, in Section 19-15-11 the word "INSULATOR". There were two listed there. Maybe the right ones? Maybe not.

So I paged one page back and saw Section 19-15-10 with three INSULATORs listed, 1319 797, 1733 778 and 1822 668. I then rechecked Nathan's Bbay links and, if you scroll down in the eBay listings, they do list the OE PNs (1319 797 in the first link and 1822 668 in the second link).

So when you get you Power Steering unit apart you can see which one you have. You can either buy the one you need from eBay or call Andy Bernbaum and buy one of the ones he has.

Hope that helps you the next time you search. (Again, sorry for not posting the pdf Index in the "How to" thread - fixed now).

If I recall correctly it was Sid that made the nylon insulator. I don't think there are any for sale

56D500boy, (I don't know your name) Thanks! You are WAY better at this than I am.

I don't think I'm downloading the PDF's right. My page doesn't give me a sweet "find" box but it does give me something. Let me see if I can put a screenshot in so you can see what I'm working with.

Crap, I give up for now... I can't even find where the darned screenshots are on my own computer. I'm going to go back to work for a while, try again later when I'm not so frustrated!

I got a picture of the isolator removed, it's 1" tall. My next task is to go on ebay and see if the seller would mind measuring it for me.

I'm now also needing a new o-ring for the pump and a new dowel pin for the steering shaft.

Let's see if I can get a couple of pics posted.

Also, I posted a photo of my computer screen, because I'm not smart enough to use a screen shot LOL.
Does that look like a pdf file to you?
Let me know and if I need to download it again and save it differently I'll do that and then look for the pump O-ring.

Thanks,

Wayne

Wayne: That is the pdf alright but you might not be opening it with Adobe Acrobat (??). Control and then "F" should get you the search box.

I think that yours is the shorter of the two offered on eBay (same seller - MoparDirect = Bernbaum??)

If you bought the longer one, you could alway make it shorter. You can't make the shorter one longer.

As for the isolator here is the one from the first link, the 1319 797 (also known as "S-140") :



Here is the taller one from the second link, the 1822668 (also known as "S-141"):

Yea, I took the isolator off and brought it in here where my pc is, opened that link back up and for sure it's the shorter one. I already ordered it.

As for the pdf, I'll have to check that out. I assumed it would have to open as a pdf but I guess it depends on how I saved the file after downloading it. I'll look into that tonight. I have to dig around and try to find the O-ring for my pump anyway.

Thanks,

Wayne: When I first started using the 55-58 Parts catalogue pdf, I downloaded it (went to the DOWNLOAD folder), then I double clicked on it (I have Adobe Acrobat Reader) and it opened. Then I saved it in my 56 D500 info directory. Now when I want to use it, I go to my 56 D500 info directory and double click on it and Adobe Reader opens it (see below):

I won't find the O-ring for you but I will give you a hint (see below):

I'm still not able to figure out how to put a screenshot on the forum or I would put the page I found up for you to see. It seems that the computer puts them in an area that I cannot see when searching for a photo. I may need to save them as a different file format so that I can use them here but, as of yet, I can't find them on my computer to be able to rename them.

So, using the number that the diagram says is the o-ring, I plugged it into the search command (control + F) and it took me to that number. The corresponding number is 1733 015. I think that might be the part number for the o-ring I need but I can't figure out what to do next. I did try googling that number, no luck, and searching ebay for that part number, and searching ebay for a 1957 dodge power steering pump o ring seal. Also no luck.

How do you get a screenshot to show up here in a thread? I assume that's how you're getting pages from the catalog to show up here.

And, is that the part number?

Am I on the right track?

Thanks,

Wayne

Parts rebuilders have access to part number lists and sources for seals that the general public doesn't have access to. Napa might have an old list as well, so you could ask them to get you a seal. The easy way around it is to pay Napa or other rebuilder to rebuild it for you. The hard way is to remove your old one and measure the cross-sectional area. Then measure the ID & OD of the pump where it will ride. Increase the cross sectional area of your measurement by up to 10-20% to account for age, and pick a new O-ring from Parker's catalog that matches what you need.

Wayne: When you take a screen shot with SHIFT - Print Screen, the image goes into a "buffer" in the computer. It sits there waiting to be pasted somewhere (a file, a program) that YOU choose. My choice is IrfanView where I process the image a bit (trimming away unnecessary information). Then I save it somewhere where I can retrieve it later.

I just did that now after searching for section 19-54-207 and the 1733 015 (see below). So you were successful in finding the PN. Congrats. You'll get even better at this with practise.

That was the first step. Finding a 1733 015 might be more challenging (Search with "1733015 Power Steering O-ring") .

Thank you! I will do that. I totally don't trust the o ring that's on it. There was some rust build up between the o ring and the tank. I separated fine but there's some metal/rust transfer on the o ring. If a new one just doesn't exist I'll have to attempt to save this one but I'd rather not try. I'm putting a ton of effort into making everything look pretty before going back under the hood so it would really suck to have it leak trans fluid all over everything due to a leaky o ring.

Also thanks for the advice re the screenshot. I hadn't thought of that and now I'm wondering why I hadn't. Duh!

Thanks again,

Wayne

I'm not having much luck searching ebay. I tried Burnbalm's site too. I may try to call him and see. Not everything can be listed on a site. I've also got a flyer from something about "antique auto" or something like that. I'll try calling them. If I can't find the correct part I may have to try to order the o ring by it's dimensions. I'd like to do that as a last resort because I'm liable to get the wrong one the first time and have it leak all over everything I broke my back painting.

Does Craig deal with that kind of stuff or does he focus mostly on brakes?
If he does other stuff too I'll call him.

If anyone has any other ideas as far as a parts source please let me know.
I got everything related to the steering painted yesterday. If I had the o ring I could reassemble the pump.

The other thing I wanted to inquire about was the pitman arm. The arm that came with the donor car is a little longer than the one that's on my gear box. It is about 3/4 of an inch longer.
My first thought was that I might have to use the one from my car but then I got thinking about it and there may be good reason for them to be slightly different.
If anyone can think about why they might be different and can tell me which why I might want to go I'd like to hear about it.
The longer one looks like, if it will fit over the spline, will work, it'll just extend the drag link a little further from the gear box. I think there will be room for it to clear the engine oil pan. If it came down to it and I had to use the shorter one for clearance reasons, I'll use what fits. But there may be a reason for the different lengths like needing to be a slightly different ratio.

Thanks,

Wayne

The PS pitman arms were a bit longer on the PS cars than they are on the manual steering cars. I'm pretty sure the reason for that is on the PS Gears the Pitman shaft sits back jut a bit further than the manual steering pitman shaft when the gear is bolted into the car.

I ran into that when I did the You Turn PS conversion on my 57 Plymouth.

Also I didn't see it in you pictures but maybe just overlooked it or you have it somewhere else, but as far as I know the 57-8s used a wedge shaped spacer behind one of the mounting bolts that connect the steering gear to the frame.

Yes, Mopar-Direct is the ebay handle for Bernbaums. The price difference is because the ebay price has the shipping charges already built in.

Yes, you are correct. There is a wedge shaped spacer that spaces the gear out from the frame. I didn't have a pic of it because it and the mounting bolts were all soaking in parts washing fluid. But, yea, I hadn't thought about that. The manual gear is much thinner over all so, if it weren't for the spacer it would sit closer to the frame. With the spacer in there...I'm not sure how it's going to work out now that I think about it.

I actually don't know how you're supposed to set those stepped spacers up when mounting a gear. I removed the gear on my buddy's 62 Dodge and just put it back on where it "seemed right" if that means anything. But now I don't know if I should have done something different with the spacer on it. I would have guessed the spacer is just there to keep the rack spaced out evenly from the frame top and bottom but there may be more to it than I'd thought about.

I took some dimensions off the steering pump in an effort to try to identify the correct O ring.
I'm not sure if I can totally trust my numbers though because all I have to measure with is a set of dial calipers and you can't reach directly over the diameter because the internals of the pump are still mounted to the case. I'll try to add a pic of the pump so that makes more sense. There's a gasket in there that I wouldn't want to have to find, in addition to the O ring seal, if it were to get destroyed. So I'm going to try to avoid that unless I find some sort of kit that includes the o ring and gaskets and suck for that particular pump. I really took my time and am pretty comfortable with that set of calipers. I would say I came within a few thousandths of the actual diameter. I came up with 5.314" where the pump housing mates with the cover/tank. I see a width of .165, a depth of .100". I don't know for sure but I would guess that the seal sticks up by at least .002. which matches my measurement of the OD of the O ring while still installed in the slot of 5.315 to 5.316.
The O ring is really hard. I'm shocked it didn't break in removal. It's width is .154 and "height" or "depth" is .122

But, with the numbers I now have I could buy several o rings close to the size I measured and just use the one that works the best.
If I don't find the exact O ring for that pump soon I'll have to just try to get a bunch of O rings and do it like that.

I still haven't tried Burnalm, Allpar or Atlas Obsolete. I used Atlas for my fuel pump a few years ago and was shocked at how much the pump costed me. I forget the number but it was somewhere around the $200 to $250 range! I know I was being a smart azz but I asked the guy if he was rebuilding them with gold parts. He failed to see the humor in that. Since then I found another pump that looks to be a usable core if I can still get rebuild parts for it.

I'll try those sources I mentioned and let you guys know what I find out.

I'll be back,

Wayne

I thought I saw, early on in this thread, someone suggested an industrial supplier by name that I might be able to get an o ring for my pump that way. I would probably have to buy quite a few right near my calculations and then just use the one that fits the best.

Who was that and what was the name of that supplier.

I went back to the beginning of this thread and that post is either gone or I managed to miss it four times!

Thanks,

Wayne

Parker is the manufacturer, but since you only want one of them, it is best to go through a distributor. McMaster is a good source.

Yea, McMaster would probably be a good bet.

I may have solved the problem.
I was thinking about the O ring and how it is a square seal like on a front pump of a transmission and wondered if I had anything among all the leftover kits I had. I didn't but I called a local transmission rebuilder and he did. It's not quite as wide as the original o ring but it's probably wide enough. It stretched over and sits "proud" of the surface. As long as it doesn't sit to far proud of the surface it think it'll seal just fine. If it doesn't work, going to have to buy something from somewhere, like McMaster maybe. The guy I got the system from suggested Caterpillar dealer in nearby Saginaw. There's also another transmission shop in town that I've used in the past to come up with solutions outside of the box. That might be an option too.

I was really hoping it would be available as a part so there'd be no guesswork involved but it looks like that's not going to happen.

We'll see.

Thanks for everyone's help and if anyone runs across one or thinking of something else we haven't talked about yet, please let me know.

Hey guys. I just wanted to kind of cap this thread off for now by letting you know that the rubber O ring I got from that trans shop appears to have worked perfectly. I don't have fluid in it yet, that'll be the real final test but it was quite tight getting the tank to slide over the pump housing and O ring. I had to "help" it a bit with a dead blow hammer but with the paint good and dry for several weeks, it didn't even marr up the paint.

I may have a photo of it assembled I'll add.

Thanks,

Wayne

I didn't take a clear picture of it. I'll take one and add it next chance I get.

Thanks to everyone that helped me get through this project. I couldn't have done it without you.
