b. Calculate the difference between the speci-
fied valve clearance and the measured valve
clearance.
Example:
Specified valve clearance = 0.10–0.16 mm
(0.0039–0.0063 in)
Measured valve clearance = 0.20 mm
(0.0079 in)
0.20 mm (0.0079 in) - 0.16 mm (0.0063 in) =
0.04 mm (0.002 in)
c. Check the thickness of the current valve pad.
TIP
The thickness “a” of each valve pad is marked in
hundredths of millimeters on the side that touch-
es the valve lifter.
Example:
If the valve pad is marked “148”, the pad
thickness is 1.48 mm (0.058 in).
d. Calculate the sum of the values obtained in
steps (b) and (c) to determine the required
valve pad thickness and the valve pad num-
ber.
Example:
1.48 mm (0.058 in) + 0.04 mm (0.002 in) =
1.52 mm (0.060 in)
The valve pad number is 152.
e. Round off the valve pad number according to
the following table, and then select the suit-
able valve pad.
TIP
Refer to the following table for the available
valve pads.
Example:
Valve pad number = 152
Rounded value = 150
New valve pad number = 150
f. Install the new valve pad “1” and the valve lift-
er “2”.
TIP
• Lubricate the valve pad with molybdenum dis-
ulfide oil.
• Lubricate the valve lifter with engine oil.
• The valve lifter must turn smoothly when rotat-
ed by hand.
• Install the valve lifter and the valve pad in the
correct place.
