Wiper transmission reburbish and paint prep ???
« on: February 27, 2014, 04:56:37 AM »


Wondering what people ususally do with these. I need to get my wiper transmission ready to go back in the car.

One of the three ball and socket joints has excessive play in it. The other two seem to be fine. How would you tighten that one back up?

How do you clean and re-lube the three ball and sockets joints without drilling out the rivets and opening them up......or should you drill out the rivets and replace them later?

The rotating posts that the wiper arms go on turn ok but there is a small amount of resistance. You can turn them easily by hand but the are not free spinning............Is that normal?.........Do these need to be re-lubed or just leave them alone?

How do you clean the whole assembly and prep for paint. I have surface rust, factory paint, and old paint job overspray on mine. I don't want to bead blast them for fear of getting media in the joints. Just do the best you can by hand?

Thanks.....Dave

Ok, so my first question would be is it the ball or the socket that has the extra wear? My thoughts would be to replace the one piece (unless both have worn evenly) scuff the whole assembly, paint/(plate?),  lube,  install.

Dave,

I recently completed my wiper transmission not too long ago. It looked exactly like yours when I took it off the car. I soaked the entire assembly in Evaporust for a couple of days. After the Evaporust bath I disassembled what could be removed, zinc plated the bolts and wired wheeled the brass parts. I then masked off the rivets and those parts that should remain natural, and sprayed the linkage 60% gloss black (which is what it appeared to be after the Evaporust bath).

I'm pleased with the final result.

The finished piece looks nice, almost to nice? I assume the brass will darken up and then be fine. Did you have any loose linkage on yours?

Is there such a thing?  Especially if someone is trying to restore their car to the best of their ability..??..   ;)

Linkage looks great.  Makes me want to redo mine before I install the cowl panel..

 All I am saying is if you were trying to reproduce the look of the car when it was new, I would be surprised if it shined that brightly is all. It does look like you could eat off of it though.. ;D

Yes...perhaps an overkill but brass will get that natural patina over time.

Didn't have any lose linkage with mine so I'm afraid I can't offer any advise on how to correct your problem. Hopefully others will chime in.

Darrell, don't take this as a negative response, or a criticism, but I feel the need to represent an alternative view ...  :)

Is there such a thing?  Especially if someone is trying to restore their car to the best of their ability..??..   ;)

Well, Yes, there IS such a thing as 'too nice'.. IF .. the goal is to restore to factory original condition (which is what the word 'restore' means to most of us (ie. restore to a condition it was in at a previous point in time..  typically when it rolled off the production floor, or into the dealer showroom).   

When it looks "TOO NICE", the appropriate description is 'OVER-RESTORED', which is FINE if you want your car to look as good as possible, but it's not 'restored' to factory condition in that situation.   Most shop 'restored cars' are over restored in today's environment, and probably it's driven by the customers, and judges at shows who believe 'prettier must be better'...  :)    There are some auto organizations which take off points for 'overrestored'.. as that approach drives owners and restorers back towards where they should be, and strives to preserve the closest possible representation of the manufacture for that period of time.

Thanks for the replies so far.

Bob, your wiper transmission looks great..........If you soak the entire assembly in Evapo-Rust, when it gets inside the rotating posts (that the wiper arms connect to), doesn't that have any affect on the bearings and lubricant or whatever is in there?

When you say you "disassembled what could be removed", is there anything you can diassemble besides the ball and socket joint (bolted together) that connects to the wiper motor?

Thanks.........Dave

Gary it was a joke..  Put the caffeine enriched coffee down..   ;D


Back on topic: 


Have you tried to form the socket with a hammer and punch (or socket (as in ratchet and socket socket) may work better) to tighten it around the ball?  Just a thought.
