[6pack] free spinning fan update

[Sally or Dick Taylor]

Alex---The large bolt needs to be torqued to specs during installation. The engine will try to rotate when doing this, so you'll need to keep this from happening. Either by using a flywheel lock (Pep Boys?) or use a pipe wrench on the fan extension, while tightening the large bolt.  Clean the crank threads with laquer thinner and an old toothbrush, blow out, and use the Blue loctite on the bolt.

The two dowel pins should feel tight when tapping them in place. Stake the pins with a center punch, if necessary, to make them fit tighter.

If it happens to you, don't drive it! Well after the fix (but still loose
pins), they backed out again. This time so did the crank bolt so some degree.
Happened about 10 miles from home at about 65 miles per hour. :o(

End result, red fan into the radiator, crank bolt bent about 45 degrees after
hitting the cross tube, (extension still on it) and still in the crank. Can
you imagine noise it made rotating against the cross tube. At least I am
hoping that that's the noise.

Damage:
  1.. bent crank bolt......$30
  2.. new pins (2) $3
  3.. fan fins need combing (no charge...and no leaks)
  4.. red fan needs cleaning, minor scuffing on edges.
  5.. A/C belt ok.
Plan and opinions:
  1.. Remove bent bolt with hope of no damage to end of crank and seals.
  2.. Install and "tack weld" pins to extension. (not comfortable with JB
weld) Not sure on balance issues with tack welds.
  3.. Apply heavy duty thread lock to crank bolt.
  4.. Comb out fan.
