Author Topic: Eaton CV Fan Clutch Restroation Question (Read 13011 times)

I was digging through some of my old 69 Z28 parts and I picked up this fan clutch and started to scrape away the old paint. And low and behold, I saw what I thought was the original Eaton CV application code and E14J date code. But I am no expert on the stamps, so any opinions are appreciated. And if it is original, what would be the best way to clean it up? Try and preserve it and clean off the lousy rattle can finish, or totally restore it? Thanks in advance for any input.

I recall a thread here or over at yenko.net that provided decode info. I'll see if I can find it and post the URL.

I have the code information, I was more interested in the authenticity and restoration info. If you knew where I could find that, I would appreciate it.

Here's my Kirkconnell restored clutch for comparison

BillOhio, that's a nice looking restoration. What shape was it in before you had it restored? I go back and forth on leaving it original or doing what you did. Was that for the Z in your signature? And where do I find Kirkconnell? Thanks.

This will be shocking but this is before. I believe they are corvette parts place and you will find on Google. I think they are in Florida. They did the one for my Chrysler also

I found them after an Internet search. Boy, they sure did a nice job. Fortunately, mine is not like that, that's why I can't decide what to do with it.

I like unrestored parts. No one will ever question what it is if left alone, but restored? Anyone can put that stamp on there, meaning, hard to prove it started out as a CV. If you choose the restoration route, take many pictures of the piece before restoring and put a mark, like a punch prick, in a inconspicuous place along with a picture of that to show it is, in fact, what is represented which is that part. I would like to have it, as is, myself.

clm69z28 - honestly, I would leave it in the condition it is in now.

X2 to what Bryon stated as that is in great shape. Maybe a little careful work to assist with it staying nice long term but that's almost too nice to restore.

I agree on a good clean up without removing stamp

clm69z28 · « **Reply #11 on:** July 18, 2016, 02:33:53 AM »

Ok, what would be a good procedure to clean it up? It appears to be a rattle can job, so how could I strip it and preserve the ink stamps?

68camaroz28 · « **Reply #12 on:** July 18, 2016, 11:49:41 AM »

So it was spray painted (rattle can) but not on the ink stamping? Might want to try some wax and grease remover as many times that will remove rattle can paint. Tedious but use small touch up brush to try opposite area where stamps are located. Alum cleaner used for trailers works well to give a fresh look but again your working with small brushes.

I scrapped the paint off with my finger nail once I saw the stamp. I did try a little paint then lacquer thinner and it wasn't that effective in removing the paint; my nail worked better but the back of the clutch will be tough.

Go to any hardware store and get a can of spray on paint stripper. Carefully mask off the ink stamped area. Spray on stripper. Let sit for several minutes. Use an old stiff brush to loosen down in crevices. Rinse off.

Thanks ko-lek-tor, I'll check that out and give it a try.

Just came across this. Could this be an original stamped unit even though it has the word "Eaton" stamped into it?

I carefully taped off the plated center area that has the ink stampings and glass beaded the fins to just clean them up. I left it that way. Like yours, you can still make out the ink stamps and it doesn't look over-restored. The ink stamp area is towards the radiator anyway and from the engine side it looks clean.

The clutch fan in this thread seems to be a hybrid. Part factory part OTC replacement according to the thread below.

I mixed up a weak solution of purple cleaner and with a toothbrush cleaned the center section. It left the ink stamps and patina. Then I masked that off and the hub and shot the ins aluminum with walnut shells to clean it. Then, to protect from corrosion shot it with Everbrite satin clear.
Looks good to me. Unless you have a mirror you can't see the front anyway when it's installed.

Anyone?

There were several systems pictured in that thread, Danzo, including mine which is all original to my car. WHICH of the ones posted are you questioning?

Danzo · « **Reply #22 on:** January 01, 2017, 02:24:17 PM »

Picture #1 in this thread. It shows a clutch fan with an ink stamp date code along with the word "EATON" stamped into it.

69 Zee · « **Reply #23 on:** January 01, 2017, 04:01:36 PM »

Well that's interesting

I didn't think OTC replacements had date code ink stamps on them.

clm69z28 did you ever clean this up ?

Danzo · « **Reply #24 on:** January 14, 2017, 12:16:11 AM »

Are there any other members with original clutch fans for comparison?

Thanks, Doc.

I have pics before restoration and after for my Delco fan clutch. But that won't answer your question which I believe is valid, because I don't see the EATON pressed into the original example picture here http://www.camaros.org/coolingsystems.shtml.

The restoration done by http://www.kirkconnellcorvettes.com/ was top notch. Fast return and very professional. My clutch had a little wiggle in it, so it needed replaced or restored.

Pic of my original Eaton clutch, my X77 is an 01C build.

Bad part - I spray bombed the fan and clutch black in '75 during a rebuild - thought at the time it looked better, plus I couldn't foresee the stamps and surface finish being as important then as it is today. My bad -

Good part - the paint kept the surface and the stamping intact as you see it today. I got curious about the date coding a while back during one of our other threads, scraped the paint off with a fingernail and discovered the Eaton, CV and date stamps intact (thank goodness). Now, if I could just figure out how to remove the rest of the paint without wearing all of my fingernails to the quick, and taking a month to do it -

Regards,
Steve
