1. Measure the height (H) of the cylinder head (refer to
Service
data standard
).
2. Check the mating surface of the cylinder head.
3. Mill the sharp edge of the combustion chamber.
4. Re-measure the height (H) of the cylinder head.
5. Seal the intake and exhaust valves.
6. Measure the dimension (T) between the camshaft bearing
and the valve system (refer to
Service data standard
).
7. Mill the cylinder head valve seat (refer to
Service data
standard
