I posted this on a detail thread I'm working on, but realized it should probably be a standalone question.

I am installing the hydro pulley (sheave) on my PM260Z (Kohler CV740 engine). The pulley is asymmetric - it has an offset on both sides of the pulley that are different dimensions. Does the fatter offset go toward the motor or toward the PTO clutch? Neither the Kohler or Gravely manuals give me any indication. There is no marking on the pulley that indicates this either.

Thank you!

Sit it against the shaft and see if the belt run will be strait
