1. Install the snap ring and bearing (A) if removed.

2. Install the pulley shaft and other bearing.

3. IMPORTANT: Avoid damage! The pulley with the teeth is the belt pulley. Install it so that it is lined up with the belt and tensioner pulley.

   NOTE: Pulley can engage threads at two different points on shaft. The crank pin must be 180° apart from its mating flywheel when the pulley is threaded completely. If not, remove pulley and engage threads at opposite point on shaft.
