3. When the No.1 piston is at the top dead
center, adjust the valve clearance in a se-
quence marked by the black dot.
1) When a feeler gauge is used for such
measurement, resistance to a moving
feeler gauge in the clearance should be
felt.
2) If the feeler gauge moves easily in the
clearance, it is impossible to obtain ac-
curate result.
4. If the measured value is out of specifica-
tion, readjustment shall be performed ac-
cording to the following method.
NOTE:
When the rocker arm at the intake side and
rocker arm at the exhaust side cannot be
turned with hands, it is indicated that the pis-
ton has reached the top dead center of com-
pression stroke. Turning the engine by one
more turn, the top dead center of compression
stroke of No.1 piston and No.6 piston inter-
changes.
