Detroit Fan Clutch

Postby oldspwr » Fri May 06, 2016 1:40 pm

Hi guys...

Quick question... I would like to install a fan clutch on my Dad's 671. Are there any pro's or con's to a Horton air actuated clutch, a Bendix oil operated or a conventional thermal clutch?

I like the idea of a air actuated clutch over an oil but I thought I would look for some recommendations first.

Thanks,

Tom

Tom, I know we had this conversation before and I have looked online for something simple that would fit without spending a fortune. Do you have any part numbers on what you've been looking at? I was thinking thermal but couldn't find anything.

Hi Tom, I've used Horton fan clutches for over thirty years. I think they are the best, they are either totally on or off, are easily rebuilt, parts are readily available, the on-off temperatures can be varied by which sensor you pick and you can install a override switch. I know they are expensive but maybe you can find a used one and rebuild if it needs. Get a plastic fan for it also as it will take a lot of stress off the clutch when it kicks on.

I agree. Horton is probably the best out there. You can also adapt a Mack (yeah I know) viscous style thermo-clutch to your Detroit. You need both the fan blade and the hub which with a little modification , will bolt on your Detroit pulley. Drawback is that this style is not controllable and will not work with shutters.
