Tools Required

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 gear (3) with the timing mark on top of the timing chain tensioner (4).



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



5. Remove the camshaft sprocket/actuator bolts.
6. Remove the timing chain, camshaft sprocket/actuator, and crankshaft sprockets.



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

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

Notice: Refer to Fastener Notice in the Preface section.




3. Install the timing chain tensioner.
4. Install the timing chain tensioner bolts.

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




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




Important: Always install a NEW camshaft position actuator filter (located in the camshaft pilot nose) anytime the camshaft position actuator is removed or installed. Refer to Camshaft and Bearings Cleaning and Inspection for filter changing instructions.

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



9. Align the dowel in the camshaft sprocket with the dowel hole in the camshaft.

Important: DO NOT use any type of threadlocking compound on the camshaft position actuator mounting 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.

10. Draw the camshaft sprocket onto the camshaft using the mounting bolts.

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

11. Coat the crankshaft and camshaft sprockets with clean engine oil.
12. Install the engine front cover. Refer to Engine Front Cover Replacement .
