ADJUSTING THE VALVE CLEARANCE
EXAMPLE:
Original valve pad number = 148 {thickness =
1.48 mm (0.058 in)}
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.
e. Install the new valve pad 1 and the valve
lifter 2.
NOTE:
_
• Lubricate the valve pad with molybdenum
disulfide oil.
• Lubricate the valve lifter with engine oil.
• The valve lifter must turn smoothly when
rotated by hand.
• Install the valve lifter and the valve pad in the
correct place.
f. Install the exhaust and intake camshafts,
timing chain and the camshaft caps.
NOTE:
_
• Refer to “INSTALLING THE CAMSHAFTS —
CAMSHAFTS” in chapter 4.
• Lubricate the camshaft bearings, camshaft
lobes and camshaft journals.
• First, install the exhaust camshaft.
• Align the camshaft sprocket marks with the
edge of the cylinder head.
• Turn the crankshaft counterclockwise sev-
eral full turns to seat the parts.
g. Measure the valve clearance again.
h. If the valve clearance is still out of specifica-
tion, repeat all of the valve clearance adjust-
ment steps until the specified clearance is
obtained.
