Camshaft Timing Chain, Sprocket, and Tensioner Installation

Installation Procedure




1. Install the No 1 chain vibration damper with the 2 bolts (1, 2) and tighten to 21 Nm (16 lb ft).
2. Install the chain vibration damper.
3. Install the chain assembly.
4. Check the No. 1 cylinder TDC/compression.
5. Hand tighten the crankshaft pulley bolt.




6. Turn the crankshaft counterclockwise to position the timing gear key (1) to the top.
7. Remove the crankshaft pulley bolt.




8. Check the timing marks (1) on each camshaft timing gear.





Note:
* Be sure to position the mark plate at the front of the engine.
* The mark plate on the camshaft side is colored orange.
* Do not pass the chain around the sprocket of the camshaft timing gear assembly. Only place it on the sprocket.
* Pass the chain through the vibration damper (4)

9. Align the mark plate (1), orange, with the timing mark as shown in the illustration and install the chain.




10. Place the chain on the crankshaft without passing it around the shaft.





Note:
* Be sure to position the mark plate at the front of the engine.
* The mark plate on the camshaft side is colored orange.

11. Hold the hexagonal portion of the camshaft with a wrench and turn the camshaft timing gear assembly counterclockwise to align the mark plate, orange (2), and timing mark (3).

Note: To tension the chain, slowly turn the camshaft timing gear assembly clockwise to prevent the chain from being misaligned.

12. Hold the hexagonal portion of the camshaft with a wrench and turn the camshaft timing gear assembly clockwise.





Note: The mark plate on the crankshaft side is colored yellow.

13. Align the mark plate (2), yellow, and timing mark (1) and install the chain to the crankshaft timing gear.




14. Recheck each timing mark (1, 2, 3) at TDC/compression.




15. Install the chain tensioner slipper.
