Camshafts - RH
Camshafts - RHMaterial:
Removal
1. Remove the timing drive components.
2. CAUTION: The camshafts must be in the neutral position before removing the bearing caps.
Verify the camshafts are in the neutral position.
3. CAUTION: Do not allow the camshaft to rotate from the neutral position while removing the variable camshaft timing (VCT) actuator.
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 VCT actuator bolt.
Remove the bolt and the VCT actuator.
4. CAUTION: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions. If the numbers cannot be seen, mark the camshaft bearing caps prior to removing them.
CAUTION: 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.
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. CAUTION: The camshafts must be installed in the neutral position.
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. CAUTION: The camshaft caps must be installed in their original positions or damage to the engine may occur.
CAUTION: 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. Tighten the camshaft bearing cap bolts in the sequence shown to 10 Nm (89 inch lbs.).
6. CAUTION: Do not allow the camshaft to rotate from the neutral position while tightening the VCT actuator bolt.
NOTE: Install a 3/8-inch 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 ft. lbs.) plus an additional 90 degrees.
7. Install the timing drive components.
