Needed Tools    
9S-9082     Engine Turning Tool     1    
136-4632     Timing Pin     1    The No. 1 piston at top center (TC) on the compression stroke is the starting point of all timing procedures.Note: The engine has 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 so the timing tool cannot be put in the wrong hole.

The timing tool 136-4632 Timing Pin is recommended. The timing tool can be installed in either the left side of the engine at location (2) or in the right side of the engine at timing location (4) . Remove both bolts (1) and cover (3) from the flywheel housing. Remove the plug from the timing hole in the flywheel housing.
Put the timing tool (1) through the timing hole in the flywheel housing. The long bolt that holds the cover on the flywheel housing can be used. The 9S-9082 Engine Turning Tool 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 tool engages with the threaded hole in the flywheel.

Using 9S-9082 Engine Turning Tool (1) Bolt (5) 9S-9082 Engine Turning Tool Note: If the flywheel is turned beyond the point of engagement, the flywheel must be turned in the opposite direction of normal engine rotation approximately 45 degrees. Then turn the flywheel in the direction of normal rotation until the timing tool 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 and the rocker arms can be moved by hand. If the rocker arms can not 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 tool from the flywheel. The flywheel is turned 360 degrees in a counterclockwise direction. Then reinstall the timing tool. Remember to remove the timing tool before you try to start the engine.
