[TR] Free spinning fan hub

[Alex]

Quick question with my 72 TR6. Just noticed that the fan and fan hub is free
spinning, along with the pulley for the AC. Crank is tight with the
alternator, water pump belt as well. I don't have time today to really take
time with it, but my first blush guess is the keyway slot on the fan hub is
gone. My next statement is, I cannot remmeber if there is even a slot or is it
just bolted. Any input appreciated!
