Thread the 136-4632 Timing Pin with the proper timing pin adapter into the timing hole. The timing hole is located approximately 127 to 152 mm (5.0 to 6.0 inch) above the turning hole for the engine turning tool in the flywheel housing.

Note: Never turn the engine by the crankshaft vibration damper. The crankshaft vibration damper is a precision part. Damage to the crankshaft vibration damper can result in major engine failure.
Install the proper engine turning tool into the proper location on the flywheel housing. Turn the flywheel in the direction of engine rotation. The direction of engine rotation is counterclockwise, as the engine is viewed from the flywheel end. Turn the flywheel until the Timing Pin engages with the hole in the flywheel.Note: If the flywheel is turned beyond the point of engagement, the flywheel must be turned in the direction that is reverse of normal engine rotation. Turn the flywheel by approximately 30 degrees. Then turn the flywheel in the direction of normal rotation until the Timing Pin engages with the hole in the flywheel. This procedure removes the play from the gears when the No. 1 piston is at the top center position.
Remove the front valve mechanism cover from the engine.
The inlet and exhaust valves for the No. 1 cylinder are fully closed if No. 1 piston is on the compression stroke and the rocker arms can be moved by hand. If the rocker arms cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke.Note: When the actual stroke position is identified, and the other stroke position is needed, remove the Timing Pin from the hole in the flywheel. Then turn the flywheel by 360 degrees in the direction of normal engine rotation and reinstall the Timing Pin into the hole in the flywheel.
