Deuce Fan Clutch

[dabtl]

Has anyone tried a fan clutch on the M35? Is there one that can be adapted?

It seems to me that after 40 years of service that would have been a great item to increase power. The first that I saw on a vehicle was in the 1970's I think. I am amazed the deuce never had one.

I would guess the military was just interested in simplicity not power.

well you going to move the engine back or the radiator froward? Thats about the only way to stuff a clutch in there.

An electric fan may be the way to go.

Yes, electric. You only need the fan when you are pulling a heavy load at low road speeds. Above about 30 MPH, no fan is needed. Deep water fording requires the fan belt to be removed. Of course, it isn't needed once the bottom of the radiator is wet.

Dabtl,
We have a couple 1995 Chevrolet school buses, Blue bird chassis, 3116 Cat, 5 spd. They refused to heat up in the winter, they would literally run so cold they wouldn't run. New thermostats, cold weather fronts, nothing helped. Finally we took the fans off in early December installed them again end of March or so. Just open and close the cold fronts as needed. We have a couple newer 5 spds & the automatics are fine. I have driven them all & can't tell the difference.
If you are making your living with your Deuce, or driving a pile of miles. It might be worth doing. If you joy ride, don't really haul anything, my guess is you will never re-coup your investment in fuel savings. If you work the crap out of it, or it's hot the fan will run anyway. But if you think you need to do it, have at it.

i am going to take my fan off, i just shortened my m35a2, i'll let you know if its faster with the fan gone, ill take it on the eway and cruise 10 or 20 miles, see if there isn't any power gain, or MPG gain,
i have this hunch i will not notice, but its a big enough difference, i will keep it that way and throw a couple electric fans on there, for when i am in the dream cruise,

I ordered 2 - twelve inch fans for mine and hope to have them installed this week. I also got an idea for a set of no-cost de-splined front hubs.

I use my truck quite a bit ... I think the power and MPH's are just fine ...

If I could get the MPG's up to 10 on a WMO mix, I'd be a pretty happy camper.
