Fan Clutch ID
 

I've got a fan clutch picked up years ago at a swap meet and need help figuring out what it fits. It's 7 1/4" and stamped "Eaton" and "store this face down" on the front. It also has an ink stamp "B7DA" on the face. It has the 1 3/4" small bolt pattern. I always wondered how to id these clutches as there's no part #'s on them. When I look in the AIM it shows several different clutches used so there must be some difference in these things but how do you tell them apart other than obvious sizing?

There should also be another inkstamp on there, like CV, CZ, CO or maybe even something else. http://bestsmileys.com/clueless/4.gif

That's all the help I can give you.
