My 78 f250 2wd 460 auto. The fan clutch is wore out . Im thinking of just machining a solid hub for the fan. I understand the principles behind them with fuel and horsepower savings. But honestly how much do we save. I tow a 11, 000 pound trailer with this truck and I think id like the cooling reliability of a solid fan hub.

What are your opinions?

If it's reliability, then yes go solid.


Machining? It's time investment versus vs "does it make sense to do when a rad fan spacer is like $5 from the salvage yard?"


Your call on if you want to make your own.

 

Very good point. And im thinking my pile of parts in the back 40 has a couple kicking around.

The big clutch fan will put a lot more shock load on the water pump if mounted solid.
