(b) Check that the timing marks (one and two dots) of the
camshaft drive and driven gears are in straight line on the
cylinder head surface as shown in the illustration. If not,
turn the crankshaft 1 revolution (360°) and align the
marks as above.
9. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
Using a thickness gauge, measure the clearance
between the valve lifter and camshaft.
Record the out−of−specification valve clearance
measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake
0.15 − 0.25 mm (0.006 − 0.010 in.)
Exhaust
0.25 − 0.35 mm (0.010 − 0.014 in.)
(b) Turn the crankshaft pulley 1 revolution (360°) and align
its groove with timing mark ”0” of the timing chain cover.
(c) Check only the valves indicated as shown. Measure the
valve clearance (See procedure in step (a)).
10. ADJUST VALVE CLEARANCE
(a) Remove the adjusting shim.
Turn the crankshaft to position the cam lobe of the
camshaft on the adjusting valve upward.
Position the notch of the valve lifter toward the spark
plug side.
Using SST (A), press down the valve lifter and place
SST (B) between the camshaft and valve lifter
flange. Remove SST (A).
SST 09248−55040 (09248−05410, 09248−05420)
HINT:
 Apply SST (B) at slight angle on the side marked with ”9”,
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 shal-
lowly from the outside of the cylinder head, at a slight
angle.

Remove the adjusting shim with a small screwdriver and
magnetic finger.
(b) Determine the replacement adjusting shim size by follow-
ing the Formula or Charts:
Using a micrometer, measure the thickness of the
removed shim.
Calculate the thickness of a new shim so that the
valve clearance comes within the specified value.
T ....... Thickness of removed 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.))
Select a new shim with a thickness as close as pos-
sible to the calculated value.
HINT:
Shims are available in 17 sized in increments of 0.05 mm
(0.0020 in.), from 2.50 mm (0.0984 in.) to 3.30 mm (0.1299 in.).
(c) Install a new adjusting shim.
Place a new adjusting shim on the valve lifter.
Using SST (A), press down the valve lifter and re-
move SST (B).

(d) Recheck the valve clearance.

0.15 − 0.25 mm (0.006 − 0.010 in.)
EXAMPLE: The 2.800 mm (0.1102 in.) shim is
installed and measured clearance is 0.440 mm
(0.0173 in.). Replace the 2.800 mm (0.1102 in.)
shim with a No. 12 shim.
