(c)
Turn the crankshaft 1 complete revolution (360°) and align its timing notch with the timing mark "0" of the oil pump.
(d) Check the valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance between the valve lifter and camshaft.
Valve clearance (cold):
for intake: 0.15 to 0.25 mm (0.006 to 0.010 in.)
for exhaust: 0.25 to0.35 mm (0.010 to 0.014 in.)
(2) Record any out-of-specification valve clearance measurements. They will be used later to determine the required replacement adjusting
shim.
9. ADJUST VALVE CLEARANCE
NOTICE: When rotating the camshaft with the timing chain removed, rotate the crankshaft damper counterclockwise 40° from the TDC and
align its timing notch with the matchmark of the timing chain cover to prevent the pistons from coming into contact with the valves.
(a)
Remove the fan and generator V belt.
