Items 7-12: Camshaft Sprocket, Main Bearing Cap Mounting Bolts, Oil Supply Tube, Main Bearing Caps and Camshaft Removal Note
1. NOTE: You must carry out the RH and LH camshaft timing procedure when either camshaft is serviced.
Rotate the crankshaft clockwise to position the number one cylinder at TDC.
2. Remove the retainer and position the A/C manifold tube bracket aside.
3. NOTE: The special tool must be installed on the damper and should contact the engine block, this positions the piston at TDC.
Install the special tools.
4. Install the special tools on the rear of the RH cylinder head and tighten the top two clamp bolts to 10 Nm (89 inch lbs.)
5. CAUTION: The RH camshaft sprocket is a LH threaded bolt.
Using the special tool, loosen the camshaft sprocket bolt.
6. Remove the special tools.
7. Remove the bolt and position the camshaft sprocket aside.
8. NOTE: Mark the position of the camshaft bearing caps so they can be installed in the original position.

Items 12-7: Camshaft, Main Bearing Caps, Oil Supply Tube, Main Bearing Cap Mounting Bolts, and Camshaft Sprocket Installation Note
1. NOTE: The camshaft bearing caps must be installed in the original position.
NOTE: After installing the bolts, check the camshaft for free rotation.
Position the oil supply tube, the camshaft bearing caps, and the bolts.
^ Tighten the bolts in the sequence shown in two stages.
^ Stage 1: Tighten the bolts to 6 Nm (53 inch lbs.).
^ Stage 2: Tighten the bolts to 16 Nm (12 ft. lbs.).
2. CAUTION: The camshaft gear must turn freely on the camshaft. DO NOT tighten the bolt at this time.
Install the camshaft sprocket and loosely install the bolt.
3. The camshafts must be retimed.
Item 6: Valve Seals Installation Note
1. Using the special tool, install the valve stem seal.
Item 5-3: Valve Spring, Valve Spring Retainers, and Valve Spring Retainer Keys Installation Note
1. CAUTION: If air pressure has forced the piston to the bottom of the cylinder, any loss of air pressure will allow the valve to fall into the cylinder. If air pressure must be removed, support the valve prior to removal.
Using the special tool, install the valve spring retainer keys, the valve springs and the retainers.
Item 2: Roller Follower Installation Note
1. NOTE: The roller followers must be installed in their original position.
