(1) Put the No. 1 Piston at the top center (TC) position and identify the correct stroke. Refer to Testing and Adjusting, "Finding the Top Center Position for the No. 1 Piston". Find the top center (TC) position for a particular stroke and make the adjustment for the correct cylinders. Remove the timing bolt. Turn the flywheel by 360 degrees in the direction of normal engine rotation. This will put the No. 1 piston at the top center (TC) position on the other stroke. Install the timing bolt in the flywheel and complete the adjustments for the cylinders that remain.
