The No. 1 piston at top center (TC) on the compression stroke is the starting point of all timing procedures.Note: Some engines have two threaded holes in the flywheel. These holes are in alignment with the holes with plugs in the left and right front of the flywheel housing. The two holes in the flywheel are at a different distance from the center of the flywheel. This distance ensures that the timing bolt cannot be put in the wrong hole.

Timing bolt (1) is a cover bolt. The timing bolt can be installed in either the left side of the engine at location (2) or in the right side at location (4). Remove both bolts (1) and cover (3) from the flywheel housing. Remove the plug from the timing hole in the flywheel housing.Note: This step can be performed on either side of the engine if cover (3) is located on both sides of the flywheel housing.
Put timing bolt (1) (longer bolt) through the timing hole in the flywheel housing. Tooling (A) and a 1/2 inch drive ratchet wrench are used in order to turn the engine flywheel in the direction of normal engine rotation. Normal engine rotation is counterclockwise. Normal engine rotation is viewed from the flywheel end of the engine. Turn the engine flywheel until the timing bolt engages with the threaded hole in the flywheel.
For the right side of the engine, put timing bolt (1) (longer bolt) through the timing hole in the flywheel housing. Tooling (B), tooling (C), and a 1/2 inch drive ratchet wrench are used to turn the flywheel in the direction of normal engine rotation. Normal engine rotation is counterclockwise. Normal engine rotation is viewed from the flywheel end of the engine. Turn the engine flywheel until the timing bolt engages with the threaded hole in the flywheel.

Using 9S-9082 Engine Turning Tool
(1) Timing bolt
(A) 9S-9082 Engine Turning ToolNote: If the flywheel is turned beyond the point of engagement, the flywheel must be turned in the opposite direction approximately 45 degrees. Then turn the flywheel in the direction of normal rotation until the timing bolt engages with the threaded hole. The procedure will eliminate the backlash that will occur when the No. 1 piston is put on the top center.
Remove the front valve mechanism cover from the engine.
The inlet and exhaust valves for the No. 1 cylinder are fully closed if the No. 1 piston is on the compression stroke. Also, the rocker arms can be moved by hand when the No. 1 piston is on the compression stroke. If the rocker arms cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke.Note: After the actual stroke position is identified, and the other stroke position is needed, remove the timing bolt from the flywheel. The flywheel is turned 360 degrees in a counterclockwise direction. The timing bolt is reinstalled.
