Note: Ensure that the number one piston is in the top center position (TC). Ensure that the timing
marks on gear assemblies (4) are in alignment with the timing marks on the rear housing.
Note: Do not use the alignment marks found on gears (9) and (12). Doing so will create errors. Use
the following steps to align gear (9).
14. Hold gear assembly (6) in the direction of normal engine rotation to remove the backlash. Place gear
assembly (9) on the shaft assembly. The teeth on gear assembly (9) will engage with gear assembly
(12) first. The teeth on gear assembly (9) will engage with the teeth on gear assembly (6) next. If the
teeth on gear assembly (9) do not engage properly, turn the gear assembly to the next tooth, and try
again.
15. Turn the engine in the opposite direction of normal engine rotation for approximately 45 degrees.
Turn the engine in the direction of normal engine rotation until the alignment mark on the vibration
damper and the marker on the engine are aligned. Ensure that timing marks on gear assemblies (4)
are in alignment with the marks on the rear housing.
16. Tighten the bolts on gear assemblies (4) to a torque of 240 ± 40 N·m (177 ± 30 lb ft). Tighten the
