Wiper rebuild

[Patcon]

I have 3 sets of wiper mechanisms on the bench. I finally decided I would rebuild them and plate them since I have some other items that need to go to the platers. Since I didn't know of a comprehensive rebuild thread on CZC I thought I would make one

I did the break down today

So you need to be sure on reasssembly that it looks like this or you're gonna have problems!!

I started on the single pivot end

The little clips aren't spring steel. The bend open. I might go back with snap rings on reassembly

Then the felt. I am working on replacements for these

Also shows the rubber seal that is on the face of the wiper pivot base

[Patcon]

On the wiper side of the pivot there is a tiny spring steel ring. Like a little bull ring. I need to find a source for these. Some of them were rusted away

When you pull the wiper spindle out of the base there is a wavy washer at the bottom to prevent wear

[Patcon]

This is what the single side spindle looks like

This is the drive end of the linkage

Order of the top pieces

Be careful when disassembling this! There is a spring under here and the first one I did the spring and washer went flying.

Order of the lower pieces

Another pivot

Some of the later mechanism had some different parts

This mechanism has a rubber boot on the end of it. I believe Steve Nixon offers this part as a reproduction

Here is it half disassembled

Out of the 3 mechanisms only had the spring in this orientation, but I beleive this is the correct position

The last one also had this little piece of plastic? I'm not sure of it's purpose

[Patcon]

Some of the spindles were bound up in the bases, but we managed to get them all out

Now for the questions...

How do we think these were made??

I'm thinking the main body was yellow zinc by the looks of it, but the pivots almost look like they are hard chromed (??) then riveted through the main body? The drive pivot was tacked welded to prevent rotation maybe...

Thoughts? I have some that are badly corroded. What do you do then? Clean and yellow zinc?

I think you are right on all counts, I would zinc the whole piece.  The cast aluminum triangular body that the spindle spins in has a recess inside, just pack that with hard grease, it will help take up any slack from wear in the spindle.

Are you looking for input into how the pieces were machined and constructed, or input into details about the finish applied after construction?

Both, and recommendations on how to deal with them moving forward

Interessting as my 240z whipers are all over the place.. due to very worn mechanics i guess... so maybe there comes a time that i need your topic. Maybe there is a complete repair set for this? Also.. Have you looked for a complete whipers mechanic part in the orig nissan partslist? maybe you/we can buy it new?

[Patcon]

No I haven't checked the part numbers. That would be very surprising if they were available. The only part Im not sure how you would refurbish are the ball joint ends.

I would for sure check the partnumbers at Nissan

NISSAN made a promise many years ago to make all the sportscarparts available in the coming years.. so i heard.. i don't know if this IS THE CASE !!!!!!!!!!!

But i see the most strangest parts available again for the 240Z

ARE THERE PEOPLE HERE THAT HAVE SEEN THE SAME?  (Original 240z/nissan sportscar parts with the orig nissan/datsun partnumbers on it!)

I checked all of the part numbers listed for the wipers on carpartsmanual.com against courtesyparts.com. All that @Patcon might need are NLA.
