Selection of Crankshaft Main Bearing
1. Crankcase Side
There are seven punching marks on the mating sur-
face to oil pan. This mark is correspondent to the
bearing distinguished by color. Select the relevant
bearing according to the punching mark when re-
paired.

Measurement of Mating Surfac
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).
