3. Measure:
Valve clearance
Out of specification →
Adjust.
Valve clearance (cold):
Intake valve:
0.11–0.20 mm
(0.0043–0.0079 in)
Exhaust valve:
0.25–0.34 mm
(0.0098–0.0134 in)
Measurement steps:
Turn the drive coupling counterclockwise,
and then check if cylinder #1 is at TDC of
the compression stroke with a dial gauge.
NOTE:
TDC of the compression stroke can be
found when the camshaft lobes are turned
away from each other.
Measure the valve clearance with a thick-
ness gauge 1
.
NOTE:
If the valve clearance is incorrect, record
the measured reading.
Measure the valve clearance in the follow-
ing sequence.
Valve clearance measuring sequence:
Cylinder #1
→ #2
→ #4
→ #3
ÈBow end
To measure the valve clearances of the
other cylinders, starting with cylinder #1
at TDC, turn the drive coupling counter-
clockwise as specified in the following
table.

cation, repeat all of the valve clearance
adjustment steps until the specified clear-
ance is obtained.
