[s-cars] sheared crankshaft pulley

[David Giannandrea]

In the thread about t-belt maintenance Robert Myers said he had seen two
sheared pulleys. From what I've read (and experienced with the shop that
ruined the oil pump pulling out the crankshaft seal) the crankshaft pulley
can be ruined if impact tools are used to remove the crankshaft bolt. 

Additionally, it seems fragile enough to simply fail during a proper removal
too. When assembled, the pulley is held so tightly with 300ftlbs of torqued
compression, that I doubt it can move.

Robert. Give up your stories on how it happened. We need to know.
