Author Topic: Eaton Fan Clutch, but is it right? (Read 19565 times)

doomer · « **on:** July 12, 2013, 07:46:15 PM »

I am having my engine rebuilt and the mechanic said that the oil leaked out of the fan clutch while the fan was sitting out. He said it must be replaced now.

My car is perhaps 60-80% original. I am trying not to reduce that number any further. So I checked CRG and saw the photos of the original Eaton fan clutchs, comparing them to mine. Someone at some time painted mine black, covering any potential stamps. However, the name "Eaton" is stamped into the metal. It looks just like the CRG images, minus the finish and ink stamps.

Is there another way to know if this is original other than ink stamps? Should there be a stamped in part number? I understand that they can be rebuilt, but the names I saw referenced were posted years ago. I am not sure what the best way to proceed is.

Eaton clutches were dated with ink stamps on the front face. The best Eaton (or Schwitzer) clutch rebuilder/restorer I can recommend is Dan KirkConnell, (813) 477-6217; he installs new seals, bearings, and oil, assembled as original. $175.00, turnaround 3 weeks or less, very well-known in the NCRS Corvette community.

This is the fan and clutch. The name EATON is stamped into the metal, but the ink stamps are painted over. if they were there at all.

I think this may be original, but without the ink stamps, is there any other way to know for sure?

BTW, I called Dan, real nice fellow. Price is $200 plus $20 for return shipping.

I haven't removed the fan yet, but here are a few views. The last one makes me doubt. I don't recall seeing that Eaton impressed into the metal in previus examples.

hard to tell from those pictures was looking for a red seal on the later models that look like that.
I have a ton of these will try to see if they have Eaton stamped on the front.

Yes - I have a serious hoarding problem....

Jeff, Jeff, Jeff...no wonder people are missing their stuff, you have it all. Is that the extent of your collection? You wouldn't happen to have an 834 alternator dated for a 10B 69 Impala do you?

Pacecarjeff · « **Reply #7 on:** July 13, 2013, 01:43:48 PM »

let me check for your date.

Exactly how did he determine it was bad? Some fan clutches have been observed with the Julian date / year with a part number stamped on the waterpump mounting flange.

Schwitzer clutches were dated on the mounting flange, in the format shown in the photo below; Eatons were not.

Attached are photos of my factory original 7 blade fan and Eaton clutch (from my '69 09C Z28)...
I had to do a little light sanding on the fan blade to even tell there were numbers there, but are legible after cleaning away some paint to read the PN 3947772, along with '914087' and date code 'H69' (which I believe is for August '69)..
The Eaton fan clutch still reads: 'H21J' and 'EATON CV'.. both printed, no stamps that I observed.

Bringing this back to life. Was it ever determined if this clutch fan was an original piece? I just removed one from an 05A Norwood Z that is identical right down to the Eaton stamp and black paint.
Thanks, Doc.

I have the same fan clutch the doomer posted on post #4 (3rd pic) with the word Eaton stamped into the metal. From my understanding and what I've been told here on CRG that this/these were service replacements. And that originals were ink stamped like Gary's (69Z28-RS) on post #12

I'm sure others will confirm.

Include some photos and we can hopefully confirm for you...

You need to resize the picture. There are several free sites that allow you to do this. I use PicMonkey.com. Another is befunky.com. I'm sure there are several others.

If your still having trouble and unable, you can email them to me and I'll resize and post for you.

Danzo · « **Reply #19 on:** September 03, 2016, 05:00:52 PM »

Darrell, can you post pictures of your clutch fan assembly?

Thanks, Doc.

69Z28-RS · « **Reply #20 on:** September 03, 2016, 05:14:53 PM »

Danzo sent me his clutch/fan photos, which were a bit too large. I've resized them slightly and they are pictured below.

Danzo: what's been posted previously would imply that your clutch is an OTC unit, and not a factory installed unit, since it's stamped 'EATON' rather than 'inked' with a date. Your unit has also been spray painted, which would have obscured any ink stamped info if it were there.

69Z28-RS · « **Reply #21 on:** September 03, 2016, 05:15:54 PM »

.. and his last photo is here...

Danzo · « **Reply #22 on:** September 04, 2016, 12:21:13 AM »

Gary, thank you for posting my pictures. The only problem I have with this being an OTC piece is that the 772 B69 fan and the clutch assembly were all painted black at the same time. I find it hard to believe someone would change the clutch and bother to reapply paint. Did these come as an assembly(fan and clutch together) OTC? Hopefully Darrell will post pictures of his. The saga continues.

Doc.

Doubt the fan and the clutch came as an assembly because of the different manufacturers - in your case, Schwitzer for the fan (Hayes-Albion produced the unstamped version) and Eaton for the clutch. It would've been necessary to bolt the two together and then repackage the assembly in the parts supply chain somewhere.
Maybe both were repainted together by a PO.
You won't be able to see the clutch stamp once installed in any case.

Just FYI, I have recently discovered "Paint" which is a program which came with my computer. PC, not mac. Re-sizes pics easily. I to use photoshop, but now I can re-size in no time using "Paint". I think most everyone with a computer has this program.

I am using an app on my android phone called reduce photo size. I select the picture and hit reduce and select something like 640x480 and save. Works great

Edgemontvillage · « **Reply #26 on:** September 05, 2016, 04:37:46 PM »

Photos of the original Eaton CV fan clutch from my 2B Norwood RS/Z.

No Eaton stamp on the bottom of the face. B5J (decodes: "B" February, "5" day of month, "J" 1969)

1.5" to top of flange (no stamp on flange edge)

69 Zee · « **Reply #27 on:** September 10, 2016, 05:56:44 PM »

Here you go Doc, my fan clutch with the Eaton stamped into the metal. Again, my understanding is that these were service replacements.

Danzo · « **Reply #28 on:** September 21, 2016, 01:29:52 AM »

Does anyone have a service replacement fan clutch for comparison?

Thanks, Doc.

doomer · « **Reply #29 on:** April 14, 2017, 01:52:23 PM »

Thanks everyone for keeping the discussion going. I believe the service replacement theory is the best one so far.

Kirkconnel corvette does a great job restoring them if it's the original and you want to save it

Ditto what he said. I got mine back in two weeks and it looks awesome.

I'd say worth it. Looks better than NOS to me.

Thanks for the info -
