Flywheel housing RH Side (1) Timing hole | |
- Remove plug (1) from the timing hole that is located in the flywheel housing. Install the assembled timing pin into the timing hole.
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 threaded hole. This procedure eliminates the backlash from the gears when the No. 1 piston is at the top center position.
- Install tool (A) into the center of the vibration damper.
Tool (A) is used for turning the flywheel in the flywheel housing. Turn the damper in the direction of engine rotation. The direction of engine rotation is counterclockwise, as the engine is viewed from the flywheel end. Turn the damper until the timing pin engages with the threaded hole in the flywheel.
- Remove the valve mechanism cover from the engine.
Refer to Disassembly and Assembly, KENR5159, "Valve Mechanism Cover - Remove and Install".
- 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 bolt from the flywheel. Then turn the flywheel by 360 degrees in the direction of normal engine rotation and reinstall the timing bolt.
