Shane

M20 x 1.5 pitch

Also wat direction is it too Undo, and the best way to Take it off

M20 x 1.5 like Dangerous has said, RH thread.... which means clockwise to tighten, counter-clockwise to loosen.

Best way to get the pulley off would be undo the bolt with a socket (I think it's 30mm from memory), then use a pulley puller to gently and evenly pull the pulley off the crank.
