Timing Drive Components

Removal

CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

CAUTION: Failure to verify correct timing drive component alignment will result in severe engine damage.

1. Remove the engine front cover.

2. NOTE: This pulse wheel is used in several different engines. Install the pulse wheel with the keyway in the slot stamped 30RFF (orange in color).

Remove the ignition pulse wheel.





3. Install the crankshaft pulley bolt and washer.





4. CAUTION: Only use hand tools when removing or installing the spark plugs or damage can occur to the cylinder head or spark plug.

NOTE: Use compressed air to remove any foreign material in the spark plug well before removing the spark plugs.

Remove the 6 spark plugs (1 shown).





5. Rotate the crankshaft clockwise to position the crankshaft keyway in the 11 o'clock position and position the camshafts in the correct position. This will position the No. 1 cylinder at top dead center (TDC).
^ Verify that the camshafts are correctly located. If not, rotate the crankshaft one additional turn and recheck.





6. Rotate the crankshaft clockwise 120 degrees to the 3 o'clock position to position the RH camshafts in the neutral position.





7. Verify that the RH camshafts are in the neutral position.





8. Remove the RH timing chain tensioner arm.
1 Remove the 2 bolts.
2 Remove the tensioner.
3 Remove the tensioner arm.





9. Remove the RH timing chain.





10. Remove the 3 bolts and the RH variable camshaft timing (VCT) assembly.





11. Rotate the crankshaft clockwise 600 degrees (1-2/3 turns) to position the crankshaft keyway in the 11 o'clock position. This will position the LH camshafts in the neutral position.





12. Verify the LH camshafts are in the neutral position.





13. Remove the LH timing chain tensioner and tensioner arm.
1 Remove the 2 bolts.
2 Remove the tensioner.
3 Remove the tensioner arm.





14. Remove the LH timing chain.





15. Remove the 4 bolts and the LH VCT assembly.





16. Remove the pulley bolt, washer and the crankshaft sprocket.
