5. With the valve spring in a compressed state, remove the cam-
shaft pliers by securely setting the outer circumference of the
valve lifter with the end of the lifter stopper.
●Hold the lifter stopper by hand until the shim is removed.
CAUTION:
Do not retrieve the camshaft pliers forcefully, as the cam-
shaft will be damaged.
6. Move the rounded hole of the adjusting shim to the front with a
very thin screwdriver or like that.
●When the adjusting shim on the valve lifter will not rotate
smoothly, restart from step 4 to release the end of the lifter
stopper from touching the adjusting shim.
7. Remove the adjusting shim from the valve lifter by blowing air
through the rounded hole of the shim with an air gun.
CAUTION:
To prevent any remaining engine oil from being blown
around, thoroughly wipe the area clean and wear protective
goggles.
8. Remove the adjusting shim by using a magnetic hand.
9. Measure the thickness of the adjusting shim using a micrometer.
●Measure near the center of the shim (the part that touches the
camshaft).
10. Select the new adjusting shim from the following methods.
SBIA0185E
SBIA0186E
SBIA0187E
Calculation method of the adjusting shim thickness:
R = Thickness of removed shim
N = Thickness of new shim
M = Measured valve clearance
Intake
N = R + [M - 0.28 mm (0.0010 in)]
Exhaust
N = R + [M - 0.30 mm (0.0118 in)]
