18. REMOVE TIMING BELT
(a) Set the No. 1 cylinder to the TDC/compression.
(1) Temporarily install the crankshaft pulley bolt and
washer to the crankshaft.
(2) Turn the crankshaft clockwise, then align the timing
mark of the crankshaft timing pulley with the oil
pump body.
(3) Check that the timing marks of the camshaft timing
pulleys and the timing belt No. 3 cover are aligned.
If not, turn the crankshaft by 1 revolution (360).
(4) Remove the crankshaft pulley bolt.
(b) If reusing the timing belt, check that there are 3 installa-
tion marks on the timing belt as shown in the illustration.
(1) If the installation marks have disappeared, put new
installation marks on the timing belt before remov-
ing.
(c) Set the No. 1 cylinder to approximately 60 BTDC/com-
pression.
(1) Turn the crankshaft counterclockwise by approxi-
mately 60.
NOTICE:
If the timing belt is disengaged, having the crankshaft
pulley set at the wrong angle can cause contact of the pis-
ton head with the valve head when removing the camshaft
timing pulley and camshaft, which causes damage. So al-
ways set the crankshaft pulley at the correct angle.
(d) Remove the timing belt tensioner.
NOTICE:
Do not reinstall the tensioner with its plunger extended.

(d) If there is wear or damage on only one side of the belt,
check the belt guide and alignment of each pulley.
(e) If there is noticeable wear on the belt teeth:

Check the timing cover for damage.

Check that the gasket has been installed correctly.

Check for foreign objects on the pulley teeth.
If there is any doubt about the belt condition, replace the timing
belt.
54. INSPECT CAMSHAFT
(a) Inspect the camshaft for runout.
(1) Place the camshaft on V-blocks.
(2) Using a dial indicator, measure the runout at the
center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the runout is greater than maximum, replace the camshaft.
(b) Inspect the cam lobes.
(1) Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
43.132 to 43.232 mm (1.6981 to 1.7020 in.) for intake
43.010 to 43.110 mm (1.6933 to 1.6972 in.) for exhaust
Minimum cam lobe height:
42.98 mm (1.6921 in.) for intake
42.86 mm (1.6874 in.) for exhaust
If the cam lobe height is less than minimum, replace the cam-
shaft.
(c) Inspect the camshaft journals.
(1) Using a micrometer, measure the journal diameter.
Journal diameter:
26.959 to 26.975 mm (1.0614 to 1.0620 in.)
If the journal diameter is not as specified, check the oil clear-
ance.
55. INSPECT CYLINDER HEAD SET BOLT
(a) Using vernier calipers, measure the tension portion diam-
eter of the bolt.
Standard outside diameter:
8.95 to 9.05 mm (0.3524 to 0.3563 in.)
Minimum outside diameter: 8.75 mm (0.3445 in.)
If the diameter is less than minimum, replace the bolt.

79. INSTALL NO.3 CAMSHAFT SUB-ASSY
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while being installed. If the
camshaft is not kept level, the cylinder head or camshaft
may be damaged. To avoid this, the following steps must
be carried out.
(a) Apply new engine oil to the thrust portion and journal of
the camshaft.
(b) Align the timing marks (1 dot marks) of the camshaft drive
and driven gears.
(c) Place the camshaft on the cylinder head.
(d) Install the 5 bearing caps in their proper locations.
(e) Apply a light coat of engine oil to the threads of the bear-
ing cap bolts.
(f) Using several steps, tighten the 10 bearing cap bolts uni-
formly in the sequence shown in the illustration.
Torque: 16 NVm (163 kgfVcm, 12 ftVlbf)
(g) Remove the service bolt.
80. INSTALL CRANKSHAFT TIMING PULLEY
(a) Align the keyway of the timing pulley with the key located
on the crankshaft, then slide the timing pulley into place.
NOTICE:
Do not scratch the sensor area of the crankshaft timing
pulley.
(b) Install the timing belt plate with the bolt.
Torque: 8.0 NVm (82 kgfVcm, 71 in.Vlbf)

pair the gasket with seal packing when the crack length is within
2 to 3 cm (0.79 to 1.18 in.). Replace the gasket when the crack
length is 3 to 4 cm (1.18 to 1.57 in.) or longer.
