ADJUSTING THE VALVE CLEARANCE
CHK
ADJ
NOTE:
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
equivalent to the original.
c. Round off the original valve pad number
according to the following table.
Last digit Rounded valve
0 or 2 0
5 5
8 10
EXAMPLE:
Original valve pad number = 148 (thickness
= 1.48 mm)
Rounded value = 150
d. Locate the rounded number of the origi-
nal valve pad and the measured valve
clearance in the valve pad selection
table.
The point where the column and row in-
tersect is the new valve pad number.
The new valve pad number is only an
approximation. The valve clearance must be
measured again and the above steps should
be repeated if the measurement is still incor-
rect.
