Assembly
VALVES, VALVE SPRINGS AND VALVE SEALS INSTALLATION1. Coat valve stems with engine oil. Insert the valves in the valve guides.
NOTE: Make sure the valves move up and down smoothly.
2. Install the spring seats on the cylinder head.
3. Install the valve seals using the valve guide seal installer.
NOTE: Exhaust and intake valve seals are not interchangeable.
4. Install the valve spring and valve retainer, then install the valve spring compressor. Compress the spring and install the valve keepers.
NOTE: Place the end of the valve spring with closely wound coils toward the cylinder head.
5. Lightly tap the end of each valve stem two or three times with a plastic mallet to ensure proper seating of the valve and valve keepers.
NOTE: Tap the valve stem only along its axis so you do not bend the stem.
CAMSHAFT, ROCKER ARMS AND CAMSHAFT SEAL/PULLEY INSTALLATION
CAUTION:
- Make sure that all rockers are in alignment with their valves when torquing the rocker assembly bolts.
- Valve locknuts should be loosened and adjusting screws backed off before installation.
- To prevent the rocker arm assembly from coming apart, leave the camshaft holder bolts in the holders.
1. After wiping down the camshaft, camshaft seal and journals in the cylinder head, lubricate both surfaces and install the camshaft.
2. Clean and install the oil control orifice with a new O-ring.
3. Turn the camshaft until its keyway is facing up (No. 1 piston TDC).
4. Apply liquid gasket (Part No. 08718-0001 or 08718-0003) to the head mating surfaces of the No. 1 and No. 5 camshaft holders.
- Apply liquid gasket to the shaded areas.
5. 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.
6. 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: 20 Nm (2.0 kgs.cm, 14 ft.lbs.)
Apply engine oil to the threads.
6 mm bolts: 12 Nm (1.2 kgs.cm, 8.7 ft.lbs.)
Apply engine oil to the threads.
6 mm bolts: (11), (12), (13), (14)
7. Install the back cover, then install the camshaft pulley.
