- Prelube the engine. Refer to System Operation, Testing and Adjusting, "Engine Prelube". Use the electrically driven manual barring group in order to turn the engine flywheel in the direction of normal engine rotation. Turn the flywheel in the direction of normal engine rotation until crankshaft timing pin (5) can be installed through mounting bracket (4) . Then, install crankshaft timing pin (5) so that crankshaft timing pin (5) is engaged in the flywheel bracket for timing (3) .
Note: Prelube the engine before you rotate the crankshaft in order to perform service work. Rotating the crankshaft before prelube may damage the crankshaft bearings if the mating surface is dry.
Note: If the flywheel is turned beyond the point of installing the timing pin, the flywheel must be turned opposite the direction of normal rotation. Turn the flywheel opposite the direction of normal rotation for approximately 20 degrees. Then, turn the flywheel in the direction of normal engine rotation until the timing pin can be installed in the flywheel bracket for timing. This procedure is required to ensure that the play is removed from the timing gears.

- Remove the valve cover from the No. 1 cylinder head.
- 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 cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke. Refer to System Operation, Testing and Adjusting, "Crankshaft Position for Fuel Timing and Valve Lash Adjustment".
Note: If the actual stroke position is incorrect and the other stroke position is needed, remove all timing pins from the engine. After all of the timing pins have been removed, rotate the flywheel for 360 degrees in the direction of normal rotation.
