11) Turn the crankshaft pulley clockwise until arrow
mark on the camshaft sprocket is set to position
shown in the figure.
NOTE:
Turn the crankshaft using socket wrench.
12) Measure the #1 cylinder intake valve and #3
cylinder exhaust valve clearance by using thick-
ness gauge (A).
NOTE:
• Insert the thickness gauge in as horizontal a di-
rection as possible with respect to the shim.
• Measure the exhaust valve clearances while lift-
ing-up the vehicle.

14) Further turn the crankshaft pulley clockwise.
Using the same procedures described previously,
and then measure the valve clearances again.
(1) Set the arrow mark on camshaft sprocket to
position shown in the figure, and then measure
the #2 cylinder exhaust valve and #3 cylinder in-
take valve clearances.
(2) Set the arrow mark on camshaft sprocket to
position shown in the figure, and then measure
