Nitro 2WD V6-4.0L (2007)
TIMING GEAR ALIGNMENT
NOTE: Rocker arm and shaft assembly can be installed either prior to or after (preferred) cylinder head installation.
1. Rotate camshaft gears to the position shown in (1, 8, 9). With the camshaft gears in these positions the lobes are in a neutral position (no load to
the valve). This will allow the rocker arm shaft assembly to be tightened into position with little or no valve spring load on it.
2. Install the rocker arm and shaft assembly making sure that the identification marks face toward the front of engine for left head and toward the rear
of the engine for right head.
3. Tighten rocker arm/shaft assembly bolts in sequence to 31 Nm (275 in. lbs.).
