− VALVE CLEARANCE
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.
INSPECT VALVE CLEARANCE
Check only the valves indicated.
Using a thickness gauge, measure the clearance
S
between the valve lifter and camshaft.
Record the out−of−specification valve clearance
S
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.)
Turn the crankshaft pulley 1 revolution (360°) and align
its groove with timing mark "0" of the timing chain cover.
Check only the valves indicated as shown. Measure the
valve clearance (See procedure in step (a)).
ADJUST VALVE CLEARANCE
Remove the adjusting shim.
Turn the crankshaft to position the cam lobe of the
S
camshaft on the adjusting valve upward.
Position the notch of the valve lifter toward the spark
S
plug side.
Using SST (A), press down the valve lifter and place
S
SST (B) between the camshaft and valve lifter
flange. Remove SST (A).
SST 09248−55040 (09248−05410, 09248−05420)
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.
