VALVE CLEARANCE
INSPECTION
HINT:
Inspect and adjust the valve clearance when the engine is cold.
1. REMOVE RH FENDER APRON SEAL
2. DRAIN ENGINE COOLANT
3. REMOVE V-BANK COVER
(a) Using a 5 mm hexagon wrench, remove the 3 cap nuts.
(b) Loosen the V-bank cover fastener counterclockwise.
(c) Remove the V-bank cover.
4. REMOVE AIR INTAKE CHAMBER ASSEMBLY (See
page EM-31)
5. REMOVE IGNITION COILS
6. DISCONNECT UPPER RADIATOR HOSE FROM WA-
TER OUTLET
7. REMOVE CYLINDER HEAD COVERS
(See page EM-31)
8. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with the
timing mark º0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 (IN and EX) are
loose.
If not, turn the crankshaft 1 revolution (360°) and align the mark
as above.
9. INSPECT VALVE CLEARANCE
(a) Check only those valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record out of specification valve clearance mea-
surements. They will be used later to determine the
required replacement adjusting shim.
Valve clearance (Cold):
Intake0.15 - 0.25 mm (0.006 - 0.010 in.)
Exhaust0.25 - 0.35 mm (0.010 - 0.014 in.)

(b) Turn the crankshaft 2/3 of a revolution (240°), and check
only the valves indicated in the illustration. Measure the
valve clearance. (See step (a))
(c) Turn the crankshaft a further 2/3 of a revolution (240°),
and check only the valves indicated in the illustration.
Measure the valve clearance. (See step (a))
10. ADJUST VALVE CLEARANCE
(a) Remove the adjusting shim.
(1) Turn the camshaft so that the cam lobe for the valve
to be adjusted faces up.
(2) Turn the valve lifter with a screwdriver so that the
notches are perpendicular to the camshaft.

(3) Using SST (A), press down the valve lifter and place
SST (B) between the camshaft and valve lifter. Re-
move SST (A).
SST 09248-55040 (09248-05410, 09248-05420)
HINT:

Apply SST (B) at a slight angle on the side marked with
º9º or º7º, at the position shown in the illustration.

When SST (B) is inserted too deeply, it will get pinched by
the shim. To prevent it from being stuck, insert it gently
from the intake side, at a slight angle.

Using a small screwdriver and magnetic finger, remove
the adjusting shim.
(b) Determine the replacement adjusting shim size according
to these Formula or Charts:
(1) Using a micrometer, measure the thickness of the
removed shim.
(2) Calculate the thickness of a new shim so the valve
clearance comes within the specified value.
T .......... Thickness of used shim
A .......... Measured valve clearance
N .......... Thickness of new shim
Intake
N = T + (A - 0.20 mm (0.008 in.))
Exhaust
N = T + (A - 0.30 mm (0.012 in.))
(3) Select a new shim with a thickness as close as pos-
sible to the calculated values.
HINT:
Shims are available in 17 sizes in increments of 0.050 mm
(0.0020 in.), from 2.500 mm (0.0984 in.) to 3.300 mm (0.1299
in.).
