ADJUSTING THE VALVE CLEARANCE
NOTE:
@
• Cover the timing chain opening with a rag to
prevent the valve pad from falling into the
crankcase.
• Make a note of the position of each valve
lifter 1 and valve pad 2 so that they can be
installed in the correct place.
b. Select the proper valve pad from the follow-
ing table.
Valve pad thickness
range
Nos.
120 ~ 240 2.40 mm
NOTE:
@
• The thickness a of each valve pad is
marked in hundredths of millimeters on the
side that touches the valve lifter.
• Since valve pads of various sizes are origi-
nally installed, the valve pad number must be
rounded in order to reach the closest equiva-
lent to the original.
c. Round off the original valve pad number
according to the following table.
Last digit
0 or 2

EXAMPLE:
Original valve pad number = 148 (thickness
=1.48 mm)
Rounded value = 150
d. Locate the rounded number of the original
valve pad and the measured valve clear-
ance in the valve pad selection table. The
point where the column and row intersect is
the new valve pad number.
NOTE:
@
The new valve pad number is only an approxi-
mation. The valve clearance must be mea-
sured again and the above steps should be
repeated if the measurement is still incorrect.
