Took that fron hub off and it is machined to fit perfectly to the balancer.
Underneath it there was a flathead allen screw securing the balancer.
I have a 41 Chevy truck with a 216, Might just put this in and add a simple turbo to it.
Curious indeed. In a standard car/truck installation the fan blades run very close to the radiator core . . . with that hub installed that snout would protrude through the radiator core (let alone the pulley or gear that is to run on it).
Has to be an agricultural/industrial application with the radiator situated higher - or with more clearance and a shroud. Perhaps a big truck as suggested but with the heater hose outlets plugged a road-going application seems unlikely.
That three bolt mounting flange (attached via two head bolts) is in play here. What's it for? Why are the standard generator mounting holes apparently unused?
