EN-47719 Tensioner Compressor

1. Remove the engine front cover. Refer to Engine Front Cover Replacement.
2. Align the crankshaft timing mark (1) to the timing mark on the bottom of the timing chain tensioner (2).
3. Align the timing mark on the camshaft position actuator gear (4) with the timing mark on top of the timing chain tensioner (3).



4. Remove the camshaft position actuator bolts.
5. Remove the timing chain, camshaft position actuator, and crankshaft sprockets.



6. Remove the timing chain tensioner bolts.
7. Remove the timing chain tensioner.



8. Remove the crankshaft sprocket.



9. Remove the timing chain dampener bolts.
10. Remove the timing chain dampener.



11. Remove and discard the camshaft position actuator filter (1) from the end of the camshaft.

Note: Always install a NEW camshaft position actuator filter anytime the camshaft actuator is removed.

1. Install a NEW the camshaft position actuator filter (1) to the end of the camshaft.



2. Install the crankshaft sprocket.
3. Apply prelube to the crankshaft sprocket thrust surface. Refer to Adhesives, Fluids, Lubricants, and Sealers.



4. Install the timing chain tensioner.

Caution: Refer to Fastener Caution in the Preface section.

5. Install the timing chain tensioner bolts.

Tighten
Tighten the bolts to 21 N·m (15 lb ft).




6. Using the EN-47719 , fully collapse the tensioner, and place he tensioner retaining pin into the retaining hole (1).



7. Align the crankshaft timing mark (1) to the timing mark on the bottom of the timing chain tensioner (2).
8. Hold the camshaft sprocket with the timing chain hanging down and install the timing chain to the crankshaft gear.
9. Align the timing mark on the camshaft position actuator gear (4) with the timing mark on top of the timing chain tensioner (3).



10. Align the dowel in the camshaft position actuator with the dowel hole in the camshaft.
11. Install the camshaft position actuator bolts.




Caution: Use only a Torx Plus® Bit when removing or installing the camshaft position actuator fasteners (1). The Torx Plus® design differs from typical Torx® fastener. Use of a standard Torx® bit on Torx Plus® fasteners may result in a rounded out fastener head or incorrect faster torque.

Note: DO NOT use any type of threadlocking compound on the camshaft position actuator bolts. Usage of a threadlocking compound on the threads could lead to contamination of the camshaft position actuator, possibly resulting in potential damage to the actuator.

12. Draw the camshaft actuator onto the camshaft using the bolts.

Tighten
Tighten the bolts to 16 N·m (12 lb ft).

13. Remove the retaining pin from the timing chain tensioner in order to make the tensioner active.
14. Coat the crankshaft and camshaft sprockets with clean engine oil.
15. Install the engine front cover. Refer to Engine Front Cover Replacement.
