( 1 ) Put the No. 1 piston at the top center position and identify the correct stroke. Refer to Testing and Adjusting, "Finding the Top Center Position for the No. 1 Piston". After the top center position for a particular stroke is found and the adjustments are made for the correct cylinders, remove the timing pin. Turn the flywheel for 360 degrees in the direction of normal engine rotation. The rotation will put the No. 1 piston at the top center position on the other stroke. Install the timing pin in the crankshaft and complete the adjustments for the cylinders that remain.
( 2 ) SAE Standard Rotation Engines turn in the counterclockwise direction when the engines are viewed from the flywheel end.
( 3 ) SAE Opposite Rotation Engines turn in the clockwise direction when the engines are viewed from the flywheel end.8-Cylinder Engine
