Timing Drive Components





NOTICE: 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.

1. Install the RH primary timing chain guide and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).





2. NOTE: It is necessary to tilt the Camshaft Holding Tool toward the rear of the engine to access the rearmost secondary timing chain tensioner bolt.

Install the RH secondary timing chain tensioner and the 2 bolts.

- Tighten to 10 Nm (89 lb-in).





3. Assemble the RH Variable Camshaft Timing (VCT) assembly, the RH exhaust camshaft sprocket and the RH secondary timing chain.
- Align the colored links with the timing marks.





4. Position the RH secondary timing assembly onto the camshafts.





5. Install 2 new bolts and the original washer. Tighten in 4 stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).

- Stage 2: Loosen one full turn.

- Stage 3: Tighten to 10 Nm (89 lb-in).

- Stage 4: Tighten 90 degrees.





6. Remove the lockpin from the RH secondary timing chain tensioner.





7. NOTE: It is necessary to tilt the Camshaft Holding Tool toward the rear of the engine to access the rearmost secondary timing chain tensioner bolt.

Install the LH secondary timing chain tensioner and the 2 bolts.

- Tighten to 10 Nm (89 lb-in).





8. Assemble the LH VCT assembly, the LH exhaust camshaft sprocket and the LH secondary timing chain.
- Align the colored links with the timing marks.





9. Position the LH secondary timing assembly onto the camshafts.





10. Install 2 new bolts and the original washer. Tighten in 4 stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).

- Stage 2: Loosen one full turn.

- Stage 3: Tighten to 10 Nm (89 lb-in).

- Stage 4: Tighten 90 degrees.





11. Remove the lockpin from the LH secondary timing chain tensioner.





12. Install the crankshaft timing chain sprocket.





13. Install the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.





14. Install the upper LH primary timing chain guide and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).





15. Install the lower LH primary timing chain guide and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).





16. Install the primary timing chain tensioner arm.





17. Reset the primary timing chain tensioner.
- Rotate the lever counterclockwise.

- Using a soft-jawed vise, compress the plunger.

- Align the hole in the lever with the hole in the tensioner housing.

- Install a suitable lockpin.





18. NOTE: It may be necessary to rotate the crankshaft slightly to remove slack from the timing chain and install the tensioner.

Install the primary tensioner and the 2 bolts.

- Tighten to 10 Nm (89 lb-in).

- Remove the lockpin.





19. As a post-check, verify correct alignment of all timing marks.





20. Install new VCT housing seals.





21. NOTICE: Make sure the dowels on the Variable Camshaft Timing (VCT) housing are fully engaged in the cylinder head prior to tightening the bolts. Failure to follow this process will result in severe engine damage.

Install the LH VCT housing and the 3 bolts.

- Tighten in the sequence shown to 10 Nm (89 lb-in).





22. NOTICE: Make sure the dowels on the Variable Camshaft Timing (VCT) housing are fully engaged in the cylinder head prior to tightening the bolts. Failure to follow this process will result in severe engine damage.
