Hayden clutch 2765

[Ironmike]

Anyone know the thickness of this unit. My Mopar perf assembly is a no-go. Need something about 3/4 inch shorter.
Dang it! Brand spankin' new, too. Have to get it on the classifieds.

Funny how stuff changes when don't expect it to.

I've needed to check in on this for a while but haven't got around to it. I'm running a fixed fan right now. I can't run a clutch that I have because of clearance issues. This might be informative.

The Hayden clutch 2765 solved my clearance problem. I bought the mopar fan kit. The clutch was too long but the fan worked with the hayden clutch.

Thanks , man! Just what I needed.

Man. Gonna be reeeeal close. I got 3 1/8th from waterpump hub to rad. Might have to do a Felx-a-lite nylon.

What do guys think about that fan clutch being around 3/8 of an inch from my rad? Kinda scary?

 

[mullinax95]

That is scary. I don't know ..... make sure you have a torque strap. lol

I thought this clutch gave more clearance than that! I have a Griffin radiator and know that 3/8 wouldn't be enough. You have a stock rad?

If the clutch fins stick out more than the fan, shave the clutch fins 1/4". 1/2" or more clearance is fine.

rad is not stock. Thicker core. Not by much though. I'm stickin' with my flex a lite nylon. I ran it all last year, up to 6800 RPM. Has an 8000 RPM rating and cooled my 340 really well. I won't be revving this new stroker that high, and it fits perfect in relation to the shroud.

I thought the Hayden gave you more clearance too.

I guess it would save me time, money and aggravation to just let my seven steel blade Flexalite fan go. I dont drive it that much anyways. I have a electric fan mounted in front of the rad on stand by also.

I have the Champion 4 core radiator with the longer aluminum 70 up small block water pump. The Haydan 2765 saved my butt. Only thing that would work.

I just measured the clutch fins are exactly 1/2" from the radiator. The front-most part of the fan blade tip is 15/16" from the radiator.

I've been running the p#ss out of it. All day at Willow Spring to 6100 rpm and on the street hard too. Buzzed it to 6000 coming home from the store a 1/2 hour ago. No traction with the 416 in 1st gear. Even from a 15mph row.

In my case Im running March water pump pulley in which the thickness of it is atleast ¼"... that doesn't help things either.
