Ok, thanx, but you're only talking 1/16th, I'm gonna pull it and see what happens, I can always cut it down, yes, live & learn. Gary

Gary; I'm not using a spacer between the pulley and the fan, but I have an unusual set-up that requires me to use a 1/16" shim between the fan and the pulley. When I built the motor I thought I needeed a 3 groove crank pulley for the AC and PS. Turns out I only needed 2 grooves, but that pulley is so wide that if I didn't shim the fan out just a bit, the back of the blades would hit the outer edge of the crank pulley. Live and learn. Rono

Rono; Are you running a spacer between pulley and fan, my 1" is to big, maybe with the 2 extra blades one isn't needed?? Gary

I found a 17" 6-blade fan at Larry's. http://www.larrystbird.com/P__8600B.htmlI'll let you now how it works.

I cannot remember if you mentioned it but if you do not have a shroud, you should install one.

Been fighting what's percieved to be a heating problem on my 56 Victoria and with Greenbirds help I'm sure I'm catching up with it. Put in the restricter bypass in today (3/16") hole and temp on the gauge was effected by seeing less movement because of the opening and closing of the high flow thermostat (160) Next will be the smaller pulley when I get home from vacation. I currently have a 6 blade fan which just over 16". The 18" will be after the smaller pulley if that doesn't make me get warm and fuzzy. When I'm finally get happy with the cooling I will look to add AC, the reason for all this. The crank already has an extra pulley so I am part way there. I think when I covered the 5"x24" hole in from of the radiator that helped too forcing more air from the grille. I will look for the upper close off plates too........JD

GREENBIRD56 (6/21/2012)
According to Hayden's propaganda - the "Severe Duty" clutch runs from 80%-90% shaft speed at full engagement - and 20%-30% shaft speed at minimum. But.....they don't publish a temp versus engagement curve. I'd like to see it anyway...
I put the smaller diameter 289/302 sized pulley on my water pump - 180° high flow thermostat - and the fan noise went way up (had a six blade fixed pitch fan on there). The temperature did what I'd hoped - which was narrow the operating range - low end up to 180° and upper came down a bit. The smaller pulley was spinning the pump about 11% "overdrive" compared to stock. Finally decidedthat while the extra pump flow was good - I'd like to lower the fan rev's - and the clutch looked likethe best way to go about it. The advertised "hot" 80%/90% drive speed got the fan back down to where it was before anyway. That was still using a six blade fan - when I found the seven blade, greed set in and I had to hang another piece of aluminum in there - what can I say.
At hot idle it engages and whizes right along - fan is in the right spot in the shroud and all of those blades give good account of themselves. On the road - I don't know what happens - I'm pretty deef from all of the years in excavators, so any change in sound at speed is lost on me.The car seems to like it - but if it freed any power - the pump is probably using it!Thanks for that! I have a clutch fan on my 6.5L diesel Suburban and it's disengaged most of the time. If I'm pulling my boat up a hill long enough to get it "hot", the fan engages and you can REALLY hear it! Similarly, when it disengages, it's just as obvious. I'm hoping that it'll work about the same. I was going to install a Flex-A-Lite dual fan 4600CFM system but I was a little worried about that because they have a GVW max for them. (They use the 6000CFM model for HD use, motor homes, 3/4T trucks ETC) The fan that I have has (2) more and larger blades than original and the radiator is a 4 row instead of the original 3 row so I don't expect it to be a problem but the clutch is sort of an unknown.......

Steve, I have the same clutch and will use a Hayden 19" 6 blade 19" fan in my 55 F-600. I was planning a 190F stat and a 10 psi cap. What are you using and what does it take for your clutch to engage fully (or does it?) Regards, Rick

Thw Summit # is FLX1618P, haven't had the car out yet, but six always cooled better than four on our race cars. The fan is really sturdy, should have it fired up by the 4th.
