[6pack] Free spinning fan

[Sally or Dick Taylor]

Alex---The chances of the two pins shearing are remote, if they were ever in there, given their size and duty.  If both the fan and its extension can be turned by hand, or do not keep up with the crank damper with the engine running, I suspect that the long (3/4" diam?) bolt is either loose, or bottomed out in the crankshaft. If so, then the load on the two pins would be much greater, and could then possibly shear. If the bolt is loose, you should be able to lever the damper back and forth a bit, while considering that some of this movement could be at the thrust washers. You may want to try this test with the clutch pedal depressed to hold the crankshaft forward.

Yes, it's necessary to remove the radiator to get to the crank pulley bolt head. (I think it takes a 1-1/8" socket) Know that if this bolt does happen to be loose, there should be some associated noise coming from this end of the engine, as when revving it. The extension would likely be out of balance., and unneccessary wear could be going on between the bolt and
extension. 

It's not a big deal to drain the radiator and take a look at the bolt in question.
