7. Valve Clearance

7) Measure #1 cylinder valve clearance by using
thickness gauge.
CAUTION:
IInsert the thickness gauge in at as horizon-
tal a direction as a possible with respect to the
valve stem end face.
IMeasure exhaust valve clearances while lift-
ing-up the vehicle.
Valve clearance:
Intake: 0.20
±0.02 mm (0.0079±0.0008 in)
Exhaust: 0.25
±0.02 mm (0.0098±0.0008 in)

8) If necessary, adjust the valve clearance. to 2-2 [W7B1].>
9) Similar to measurement procedures used for #1
cylinder, measure #2, #3 and #4 cylinder valve
clearances.
NOTE:
IBe sure to set cylinder pistons to their respective
top dead centers on the compression stroke before
measuring valve clearances.
ITo set #3, #2 and #4 cylinder pistons to their top
dead centers on the compression stroke, turn
crankshaft pulley clockwise 90É at a time starting
with arrow mark on left- hand camshaft sprocket
facing up.
