Re: Schwitzer Fan Clutch Restorer
The difference is the hub length. 1/4 inch difference.

Re: Schwitzer Fan Clutch Restorer
Whatever you do don't try "reclocking" the coil spring on the non-Schwitzer fan clutches - that is a myth and doesn't work and may be harmful.
Here is kirckconnel's response when I asked about this:
=================================================
Hi Frank,
Thank you for your inquiry regarding a very old question. We're assuming that you're talking about "tightening" the spring on the Eaton fan clutch. If you'll be at Corvettes at Carlisle, stop at our booth (IA72 & IA73) and we'll show you just how an Eaton works inside. From that you'll see that "tightening" the spring has nothing to do with how the fan clutch performs. It will, however, through the spring out of the normal coil, which will eventually wear the spring out. The spring will only open or close, allowing the oil into the reservoir or not.
That said.....Dan says that in the very early cars (C1) the coil spring bracket had 3 little slots within 1/16th on an inch, which does allow for a little adjustment, which is probably where this idea of reclocking came from. Hope this helps to answer you question. Again, if you or your buddies stop by our booth, we'll have disassembled units for you to look at.
