ADJUSTMENT OF VALVE
CLEARANCE
Adjust the valve clearance in the following procedures:
1. Remove the air filter/resonator assembly and the
relevant parts installed on the cylinder head cover.
2. Remove the cylinder head cover hexagon bolts and
remove the cover.
3. Turn over the crankshaft to make No.1 cylinder
matched with the compression top dead center.
(When the camshaft sprocket notch (d) is aligned with
the timing belt rear cover triangle pointer (e) and the
crankshaft sprocket point (f) is aligned with the oil
pump housing point (g), the compression top dead
center is on the ignition sequence for No. 1 cylinder.)
