(b) Determine the replacement adjusting shim size by the fol-
lowing Formula or Charts on the next 2 pages:
(1) Using a micrometer, measure the thickness of the
removed shim.
(2) Calculate the thickness of a new shim so that the
valve clearance comes within specified value.
T ....... Thickness of removed shim
A ....... Measured valve clearance
N ....... Thickness of new shim
Intake:
N = T + (A - 0.20 mm (0.008 in.))
Exhaust:
N = T + (A - 0.36 mm (0.014 in.))
Select a new shim with a thickness as close as possible
to the calculated value.
HINT:
Shims are available in 17 increments of 0.05 mm (0.0020 in.),
from 2.50 mm (0.0984 in.) to 3.30 mm (0.1299 in.).
(c) Install a new adjusting shim.
(1) Place a new adjusting shim on the valve lifter.
(2) Using SST (A), press down the valve lifter and re-
move SST (B).

INSPECTION
1. INSPECT TIMING BELT
NOTICE:
Do not bend, twist or turn the timing belt inside out.
Do not allow the timing belt to come into contact with
oil, water or steam.
Do not utilize timing belt tension when installing or re-
moving the mounting bolt of the camshaft timing
pulley.
If there are any defects as shown in the illustration, check these
points:
(a) Premature parting
Check for proper installation.
Check the timing cover gasket for damage and
proper installation.
(b) If the belt teeth are cracked or damaged, check to see if
either camshaft or oil pump is locked.
(c) If there is noticeable wear or cracks on the belt face,
check to see if there are nicks on the side of the idler
pulley lock.
(d) If there is wear or damage on only one side of the belt,
check the belt guide and the alignment of each pulley.
(e) If there is noticeable wear on the belt teeth, check the tim-
ing belt cover for damage and check gasket has been
installed correctly and for foreign material on the pulley
teeth.
If necessary, replace the timing belt.
2. INSPECT IDLER PULLEYS
(a) Visually check the seal portion of the idler pulley for oil
leakage.
If leakage is found, replace the idler pulley.
(b) Check that the idler pulley turns smoothly.
If necessary, replace the idler pulley.

(b) Using the crankshaft pulley bolt, turn the crankshaft and
align the timing marks of the crankshaft timing pulley and
oil pump body.
6. INSTALL TIMING BELT
NOTICE:
The engine should be cold.
HINT:
When re-using timing belt:
Align the points marked during removal, and install the belt with
the arrow pointing in the direction of engine revolution.
(a) Remove any oil or water on the pulleys, and keep them
clean.
NOTICE:
Only wipe the pulleys; do not use any cleansing agent.
(b) Install the timing belt, and check the tension between the
crankshaft timing pulley and camshaft timing pulley.
7. CHECK VALVE TIMING
(a) Loosen the No.1 idler pulley mount bolt, until the pulley is
moved slightly by the spring tension.

5. INSPECT VALVE STEMS AND GUIDE BUSHINGS
(a) Using a caliper gauge, measure the inside diameter of the
guide bushing.

6.010 - 6.030 mm (0.2366 - 0.2374 in.)
(b) Using a micrometer, measure the diameter of the valve
stem.
Valve stem diameter:
Intake5.970 - 5.985 mm (0.2350 - 0.2356 in.)
Exhaust5.965 - 5.980 mm (0.2348 - 0.2354 in.)
(c) Subtract the valve stem diameter measurement from the
guide bushing inside diameter measurement.
Standard oil clearance:
Intake0.025 - 0.060 mm (0.0010 - 0.0024 in.)
Exhaust0.030 - 0.065 mm (0.0012 - 0.0026 in.)
Maximum oil clearance:
Intake0.08 mm (0.0031 in.)
Exhaust0.10 mm (0.0039 in.)
If the clearance is greater than maximum, replace the valve and
guide bushing (See page EM-40).
6. INSPECT AND GRIND VALVES
(a) Grind the valve enough to remove pits and carbon.
(b) Check that the valve is ground to the correct valve face
angle.
Valve face angle: 44.5°
(c) Check the valve head margin thickness.
Standard margin thickness:
0.8 - 1.2 mm (0.031 - 0.047 in.)
Minimum margin thickness:
0.5 mm (0.020 in.)
If the margin thickness is less than minimum, replace the valve.

If the circle runout is greater than maximum, replace the cam-
shaft.
