NOTE: Keep the cam chain away from magnetic fields.
 Before doing this procedure, check that the variable valve timing control (VTC) actuator is locked by
turning the VTC actuator counterclockwise. If not
locked, turn the VTC actuator clockwise until it stops,
then recheck it. If it is still not locked, replace the VTC
actuator.
1. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with
the pointer (B) on the engine block.
2. Set the camshafts to TDC. The punch mark (A) on the VTC actuator and the punch mark (B) on the
exhaust camshaft sprocket should be at the top.
Align the TDC marks (C) on the VTC actuator and
the exhaust camshaft sprocket. 3. To hold the intake camshaft, insert a camshaft lock
pin (07AAB-RWCA120) (A) into the maintenance
hole in camshaft position (CMP) pulse plate A (B)
and through No. 5 rocker shaft holder (C).
4. To hold the exhaust camshaft, insert a camshaft lock pin (A) into the maintenance hole in CMP pulse
plate B (D) and through No. 5 rocker shaft holder
(C).
5. Install the cam chain on the crankshaft sprocket with the colored link plate (A) aligned with the mark
(B) on the crankshaft sprocket.
