Procedure for Pin Timing

Ver imagen


Flywheel housing

(1) Timing hole

1. 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. Thenturn 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.

2. Install tool (A) into the gear in the top left-hand side of the flywheel housing.

Tool (A) is used for turning the flywheel in the flywheel housing. Turn the engine in the direction of enginerotation. The direction of engine rotation is counterclockwise, as the engine is viewed from the flywheel

end. Turn the engine until the timing pin engages with the threaded hole in the flywheel.

Note: Tooling (B) or (C) may also be used to turn the flywheel. Either of the three tools may be useddepending on the application and available space.

3. Remove the valve mechanism cover from the engine.

Refer to Disassembly and Assembly, "Valve Mechanism Cover - Remove and Install".

4. The inlet and exhaust valves for the No. 1 cylinder are fully closed if No. 1 piston is on the compression

stroke. Also, the rocker arms can be moved by hand when the piston is on the compression stroke. If therocker 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 thetiming bolt from the flywheel. Then turn the flywheel by 360 degrees in the direction of normal engine

rotation and reinstall the timing bolt.
