I have one sitting here on my desk.  It's normal.  Clockwise screws in, counter-clockwise screws out.  I only had to use a 4 ft. pipe.

      I'm trying to remove the triple V-belt pulley (As Bentley describes it) on
the end of the crankshaft. It's held on with a big bolt - which way to turn
it to loosen it?
I've tried both directions with a cheater bar on the end of the breaker bar
and an impact wrench - won't budge. Before I get out "The Pursuader" (the
6-foot pipe) someone tell me which way to turn this bolt so I don't break
it. Thanks!
