4104 671 fan hub

[Nel]

Getting the bus ready for new season, I always inspect the famous fan hub that eventually fails and launches the fan. I was just wondering if anyone has tried to drill and run a bolt thru the shaft diameter between the hub on the engine and the fan mount. I know its the rubber between the inner and outer shafts that fail, would a bolt work to keep them from seperating?

This is how I protected my radiator on the Silverside.

I've seen both drilled and screwed and straped..
