Found these photos on eBay and it got me thinking about getting my 56 Dodge wiper pivots re-plated. I can see now that getting them off the car isn't (shouldn't be) a big deal. But then the question is how much can I disassemble? Looks like the actuator arm should press out but what about the bushing?

I'm sure somebody has done this right?

Thanks Sven. I'm not capable of doing that. Anybody does this as a business?

I ordered and installed new oiled bronze bushings online and replaced the C-clips without any difficulty. Lots of rust on the shaft that hid the slot, but it is there.

Now we're talking there Gary. Do you happen to recall where you got the bushings? There are no separate bushing PNs in the Mopar catalog. Just the complete pivot assembly (at least I think so) (??)

Maybe here?:

https://bearing-solutions.isostatic.com/printitems/sleeve-bearings/m...



I found your before and after photos and reference to your use of Muggy Weld to fill in the pits. Did you drill the pits out first or just sand them?

Before (not so nice):



After (very nice):

I ordered the oiled bronze bushings online, but don't recall the source. I measured the shafts and castings and ordered by size. I think I ordered two longer parts and cut them in two, but it was some time ago and my memory is fading.

I drilled out the pits with a Dremel and small bur before sanding and filling with Muggyweld. Yours look much better than mine to start, so you should be able to clean them up much faster.

This is the modification I have done with several wiper pivots. I really think that someone has done this modification earlier on those pivots.
Normally, they are not serviceable since the sleeve is shrunk on the shaft groove.

I didn't have to change any bushings though - the problem was dirt and rust on the shafts. A good cleaning and some fine emery cloth, new grease and they are normally good for many years of service.

If you needd spacers, a stainless tube can be cut and then grinded to correct lenght by putting the tube in the mandrel of a drill machine and run it against a file and/or emery cloth.

I just checked the pivots on all 5 of my '56 Plymouths and they all have the non-serviceable collar on them. The pivot from the Fury that I parted out didn't move very easily, but it freed up quite well with just a little lubrication on the ends.

Since I know none of the history of my Plymouth, I have no idea if any modifications were made by previous owners, but I know that the way it's now assembled, I don't have to worry about that problem in my lifetime!

If I was doing it, I would grind off the peened area (red arrow), remove the lever and remove the shaft from the top side. Then drill and tap the end of the shaft and use a screw (with Loctite) to reinstall the lever.

I agree, that seems like a sensible plan. Much easier than dealing with that collar so close to the pot metal.

Yes, it's easier, but that is the fulcrum point, so any lash will result in that the shaft will eat up more material until it's loose or broken.

That could be fixed by welding it back together. That's what I did to fix my door latch. As long as you aren't likely to need to take it apart too often, that should be a good solution. Another less final solution is to screw it together with some epoxy to prevent any small movements. Burn the epoxy to take it back apart.

I can't see it clearly in the photo, but maybe the collar is meant to be a type of water seal.

FWIW, I recall that I first just cleaned and lubricated, but decided that the shafts had what I thought was too much slop in the bushing and since the bezel pitting was really bad, they had to be repaired. Perhaps my car spent its life in Seattle where it rains 300 days a year!

It's just a collar that covers the gap between shaft and bushing...

Just for clarification, my pivots are still on my car. I was just thinking ahead and mentally preparing for what will have to be done to get these plated. So I am appreciating all the comments and options that have been presented in this thread.

The bonus will be when I take them off I can repaint the area around them much better than I have so far.

I was under the dash of my 56 Dodge this morning looking at something else and while I was there, I took some photos of the underside of the wiper pivot supports. I was a bit shocked to see bolts, not studs and nuts. I imagine that re-installation without a helper up top might be a challenge.

These:

Thanks for all the hints guys. Much appreciated.

I recently found a pair of used 56 Dodge wiper pivots on eBay and they were just delivered today. I have removed the bottom plates and put the components into Rust Check "Rust Wash" so I can get a better view of the threaded end of the pivot and determine how to best disassemble.

These "new" (to me) ones are less pitted than the ones on my car but the splines are pretty much non-existant. So I will get the new ones fixed and plated and then swap the wiper arm stuff from mine into the new ones (my splines are good). Not sure about the bushings.

Here are some photos of the "new" ones today (the Rust Wash looks dark because I am using a combination of fresh green Rust Wash and some previously partially used up Rust Wash). I will leave them soak at least overnight or maybe for 2 days (??)):

I was really hoping that GaryS would be right and that there would be C-clips. *BUT* I just pulled on of the wiper pivots out of the Rust Check Rust Wash bath and, after brass wire brushing, I can not see any C-clips, at least at the upper end. What I do see, unfortunately, is a crimped-on collar, like Sven (wizard) suggested was there. Why would I even think of doubting Sven?

I might try to "stretch" collar to get it off. Barring failure there, I will use my Dremel and E-Z cut cut-off wheel to carefully (I hope) cut a slot in the collar that will allow me to open it up.

A photo of the rust "free" threaded upper end of the pivot (you can see the upper end of the bronze bushing also the very poorly defined splines (rusted away?)):

I tried to open up the collar on both of the pivots but NOPE, not happening. So out came the Dremel and a few minutes later I had cut the collar enough to pry it off.

With the collar off you can see the "C-clip" groove into which the collar was crimped. I think I will try to figure out an actual C-clip and maybe a spacer or fibre washer.

The lower, inner end, has a fibre washer for anti-friction and a thin metal spring washer/shim.

Found some 5/16" C-clips that work (1/4" was too small). With the width of the groove for the OE crimp-on collar as wide as it is, I was able to slip (force) two of the C-clips into that space.

Probably going to need some futzing with washers, etc to take of the rest of the space vacated by the OE collar but I can sort that one way or the other after I get these "new" pivot bases replated.

Before:



After (with one washer and 2 C-clips):

Pivots are back from the "Plater". Not impressed at all

Still some pits that show (the platers technique is to grind them out, rather than fill with copper, etc).

One of the pivots has a "bite" out of it that wasn't there before (I wasn't sure when I picked it up but now that I am home and checked my photos, it WAS NOT there before). Now I will have to put that on the side where the "bite" wont' show or figure out a "hack" fix to camouflage the bite.

The other pivot has an edge that is drooping such that the base will not sit flat. I can fix that by removing the excess material with my Dremel.

But still, why should I have to do any of that?

Time to find another plater. Whoever that will be will be much slower and way more expensive.

"You get what you pay for"

No kidding.

GRRR...

Hi Dave, I like your approach to the repair. Take a look at a Spiral Retainer Ring. Pic attached. Grainger will also have the "Oilite" or similar bushings.
