That link did not show any specific model number, only the whole Torqflo line.....how many blades on your fan? Armand Minnie recently blogged his use of the Torqflo 922747. Just curious as to which one you selected. Thanks.

Sir: when I click on link I get Auto Zone site showing 922747 only? Clutch fan for `76 Olds Toro. Don`t rmember about # of blades but can go look if you need. The blades do not come with the clutch.

I am a moron. I see on the title of your thread that you had the model number. Missed that. I mention the number of blades because of a warning in the Parts Interchange book that some of the replacement fan clutches come with a warning "not recommended for 7 blade fans" or some such verbage. My coach has 7 blade fan. It is funny you posted this. Because of Armand Minnies blog, I already had one of these on my "stop at Autozone" list for a spare. Thanks.

I believe that clutch is equivalent to a Hayden heavy duty 2747 a severe duty would be a 2797. Either one can use the 7 blade fan.

I believe I will give the 2747 a try. I just out on a Hayden 2797 and I am not sure I want anything that "severe" abusing our ears. The 2797 is coming on at 195 ( with a 185 thermostat) I would rather have it come on at 210 or so. I am thinking that the Severe vs. Heavy duty will not change that, just change the RPMs the clutch pulls the fan to?

Actually the opposite is true. The 2797 is the one I went through 3 of before I got Hayden to admit that they lowered the engagement temperature. It sure caused me problems but their engineers were proud of the fact that they had reduced the engagement temperature. They tried to get me to modify the coiul spring on the front to change the temperature. I refused after going through 3 of them and returned the clutches.
If you like lots of noise, unnecessary engagement, and lower mpg, then that is the clutch to use. As a severe duty clutch it will definitely move some air. It was designed for a larger diameter fan with a larger pitch than we have on a GMC.
