Example:
If the valve pad is marked “158”, the pad
thickness is 1.58 mm (0.062in)
d. Calculate the sum of the values obtained in
steps (b) and (c) to determine the required
valve pad thickness and the valve pad
number.
Example:
1.58 mm (0.062 in) + 0.05 mm (0.002 in) =
1.63 mm (0.064 in)
The valve pad number is 163.
e. Round off the valve pad number according
to the following table, and then select the
suitable valve pad.
NOTE:
Refer to the following table for the available
valve pads.
Example:
Valve pad number = 163
Rounded value = 165
New valve pad number = 165
f. Install the new valve pad “1” and the valve
lifter “2”.
NOTE:
• Lubricate the valve lifter with engine oil.
• Install the valve lifter and the valve pad in the
correct place.
• The valve lifter must turn smoothly when
rotated by hand.
g. Install the exhaust and intake camshafts,
timing chain and camshaft caps.
NOTE:
• Refer to "CAMSHAFTS" on page 5-9.
• Lubricate the camshaft bearings, camshaft
lobes and camshaft journals.
• First, install the exhaust camshaft.
• Align the camshafts marks with the camshaft
cap marks.
• Turn the crankshaft clockwise several full
turns to seat the parts.
h. Measure the valve clearance again.
i. If the valve clearance is still out of specifi-
cation, repeat all of the valve clearance
adjustment steps until the specified clear-
ance is obtained.

NOTE:
For installation, reverse the removal proce-

SYNCHRONIZING THE THROTTLE BODIES
NOTE:
Prior to synchronizing the throttle bodies, the
valve clearance and the engine idling speed
should be properly adjusted and the ignition
timing should be checked.
1. Stand the vehicle on a level surface.
NOTE:
Place the vehicle on a suitable stand.
