Camshafts - RH













Removal

1. Remove the timing drive components. For additional information, refer to Timing Drive Components Removal and Replacement.

2. NOTICE: The camshafts must be in the neutral position before removing the bearing caps or damage to the engine may occur.

Verify the camshafts are in the neutral position.





3. NOTICE: Do not allow the camshaft to rotate from the neutral position while removing the Variable Camshaft Timing (VCT) actuator or damage to the engine may occur.

NOTE: Install a 3/8-in ratchet and extension into the D-slot on the rear of the intake camshaft to hold the camshaft in place for removal of the Variable Camshaft Timing (VCT) actuator bolt.

Remove the bolt and the VCT actuator.





4. NOTICE: Cylinder head camshaft bearing caps must be assembled in their original positions. Some engines have factory markings on the camshaft bearing caps (as shown in illustration). Engines that do not have the factory markings must be marked for correct position and orientation prior to removal. Failure to install the camshaft bearing caps in their original positions may result in severe engine damage.

If necessary, mark the camshaft bearing cap position and orientation as shown in the illustration.





5. NOTICE: After loosening all of the camshaft bearing cap bolts, remove the camshaft bearing thrust caps (5R and 1R) first or damage to the thrust caps may occur.

NOTE: Make sure the camshaft bearing caps are marked as instructed in the previous step.

Loosen the bolts evenly in the sequence shown.

1. Remove the camshaft bearing thrust caps (5R and 1R).

2. Remove the remaining camshaft bearing caps.

3. Remove the camshafts from the cylinder head.





Installation

1. Position the VCT actuator onto the intake camshaft.
- Install the bolt finger-tight.





2. NOTICE: The camshafts must be installed in the neutral position or damage to the engine may occur.

Lubricate the camshafts with clean engine oil and carefully position the camshafts onto the cylinder head.

- Align the camshafts in the neutral position as shown.





3. NOTICE: The camshaft caps must be installed in their original positions or damage to the engine may occur.

NOTICE: Do not install the camshaft bearing thrust caps until all of the camshaft bearing caps have been installed or damage to the thrust caps may occur.

NOTE: Lubricate the bearing surfaces of the camshaft bearing caps with clean engine oil.

Install the camshaft bearing caps.
- Loosely install the bolts.





4. NOTE: Lubricate the bearing surfaces of the camshaft bearing thrust caps with clean engine oil.

Install the camshaft bearing thrust caps.

- Loosely install the bolts.





5. NOTE: Make sure to tighten the camshaft bearing cap bolts in sequence in 2 stages.

Tighten the camshaft bearing cap bolts in the sequence shown in 2 stages.

- Stage 1: Tighten to 10 Nm (89 lb-in).

- Stage 2: Individually loosen and then tighten each camshaft bearing cap bolt to 10 Nm (89 lb-in).





6. NOTICE: Do not allow the camshaft to rotate from the neutral position while tightening the Variable Camshaft Timing (VCT) actuator bolt or damage to the engine may occur.

NOTE: Install a 3/8-in ratchet and extension into the D-slot on the rear of the intake camshaft to hold the camshaft in place for tightening of the VCT actuator bolt.

Tighten the VCT actuator bolt to 40 Nm (30 lb-ft) plus an additional 90 degrees.





7. Install the timing drive components. For additional information, refer to Timing Drive Components Removal and Replacement.
