Special Tools Required
- Seal Guide 07NAG-PT0010A
- Installer Cup 07NAF-PT0010A

NOTE:
- To prevent the rocker arm assembly from coming apart, leave the camshaft holder bolts in the holes.

1. After wiping down the camshaft and the journals in the cylinder head, lubricate both surfaces and install the camshaft.





2. Clean and install the oil control orifice (A) with a new O-ring (B).
3. Turn the camshaft until its keyway (C) is facing up. (No.1 piston Top Dead Center (TDC).
4. Loosen all the valve adjusting screws.





5. Apply liquid gasket to the head mating surfaces (the shaded areas) of the No. 1 and No. 5 camshaft holders.
6. Set the rocker arm assembly in place and loosely install the bolts. Make sure that the rocker arms are properly positioned on the valve stems.





7. Install the camshaft oil seal (A) using the special tools as shown.
8. Make sure all the rocker arms are aligned with the valves.





9. Tighten each bolt two turns at a time, in the sequence shown, to ensure that the rockers do not bind on the valves.

Specified torque:
8 mm bolts: 22 Nm (2.2 kgf.m, 16 ft. lbs.)
6 mm bolts: 12 Nm (1.2 kgf.m, 8.7 ft. lbs.)
6mm bolts: (11), (12), (13), (14)

10. Check the back cover rubber seal for cranks and other damage.

NOTE:
- If the rubber seal is coming off, reattach it with liquid gasket. Wipe off any excess liquid gasket.

- After installing the rubber seal, check the joints. Apply liquid gasket if there is any gap or opening.
