Re: Scan of Clutch for Chris Henige..Front

Sorry, but this clutch is an aftermarket unit (non-Eaton).

Thanks, hopefully somebody can use it. I need to clean out my old parts.

The pictures confirm it. This is an aftermarket-type fan clutch, for sure. In fact, I believe that this is a non-thermal-type unit. These are the real "cheapo" type units that don't react to engine temperature. I think that they're only engine speed activated.

All non-thermal units are aftermarket. I don't think that any non-thermal type units were ever used in PRODUCTION by ANY manufacturer.

If you put this one on eBay, I'd definitely recommend a "no-reserve" auction with a LOW starting bid.

Re: Lets try this one

Joe,

Just a FYI regarding non-thermal fan clutches. There were a few rare occasions that Eaton (the original fan clutch manufacturer for the big 3)produced non-thermal fan clutches.

The first was back in 1958. This was their first design fan clutch, and was used on 1958 full size Chevys WITH AIR ONLY. As such, they are extrememly rare. Also, there were 2 design variants of this. The first one had short fins (only about 100 of these made), the later one had taller fins. As you state, these clutches had no thermal capability at all and were only 'torque limiting'. Variants of this design were also used on other GM & Chrysler cars in the time frame, however, it's production life was very short.

The second instance Eaton building a toque limiting fan clutch was in the late 60's/early 70's. These clutches had only a single application -- Chrysler Hemi
and 440-6 engines.

However, there were no instances of a Corvette using a torque limiting fan clutch.

Hope this helps.

Thanks for that information; things like that interest me very much. I was not aware that there were ever any use of these non-thermal units in PRODUCTION. Given the very limited use that you described, I'll bet that those, particualr, non-thermal units are worth a king's ransom, especially the Chrysler units considering their application.
