Variable Valve Timing Actuator Component Removal Note
WARNING: This page is about a different variant/trim than selected.
CAUTION:
- Do not rotate the crankshaft counterclockwise. The timing chains may bind, causing engine damage.
- Rotate the crankshaft counterclockwise until the keyway is in the 9 o'clock position.
- Slowly compress the camshaft timing chain tensioner (LH) piston by hand.
- Insert an approx. 1.0 mm {0.039 in}
thin wire or paper clip into the camshaft timing chain tensioner (LH) shown in the figure to hold the tensioner piston.
NOTE:
- When the timing chain removed, valve spring pressure will rotate the camshaft (LH) approx. 3 ° to a neutral position.
- Install the SST onto the camshafts (LH).
CAUTION:
- Always use an appropriate tool (TORX or TORX PLUS). If the appropriate tool is not used, it could result in damage to the bolts or the tools.
Tool size
- TORX: T55
- TORX PLUS: 55IP
NOTE:- The camshaft sprocket is integrated with the variable valve timing actuator and cannot be disassembled.
- Remove the variable valve timing actuator, camshaft timing chain and the exhaust camshaft sprocket of the LH bank as a single unit using the appropriate tools.
- Remove the SST from the camshafts (LH).
- Slowly compress the camshaft timing chain tensioner (RH) piston by hand.
- Insert an approx. 1.0 mm {0.039 in} thin wire or paper clip into the camshaft timing chain tensioner (RH) shown in the figure to hold the tensioner piston.
- Install the SST onto the camshafts (RH).
NOTE:
- The camshaft sprocket is integrated with the variable valve timing actuator and cannot be disassembled.
- Remove the variable valve timing actuator, camshaft timing chain and the exhaust camshaft sprocket of the RH bank as a single unit using the appropriate tools.
- Remove the SST from the camshafts (RH).
