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.

(c) Using several steps, loosen and remove the 10 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 5 bearing caps and No. 3 camshaft.
NOTICE:

Do not pry out the camshaft.

Be careful not to damage the contact surface of the
cylinder head that receives the shaft thrust.
30. REMOVE NO.4 CAMSHAFT SUB-ASSY
(a) Using several steps, loosen and remove the 10 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 5 bearing caps and No. 4 camshaft.
NOTICE:

Do not pry out the camshaft.

Be careful not to damage the contact surface of the
cylinder head that receives the shaft thrust.
(b) Remove the oil seal from the No. 4 camshaft.
31. INSPECT CAMSHAFT TIMING GEAR ASSY
(a) Clamp the camshaft in a vise on the hexagonal lobe.
(b) Check that the VVT-i will not turn.
(c) Cover all the oil ports with vinyl tape except the port on the
advance angle side (nearest to the convex portion)
shown in the illustration.
(d) Using the air gun, apply about 100 kPa (1 kgf/cm
2, 14 psi)
of air pressure to the port on the advance angle side.
NOTICE:
Some oil spraying will occur. Be prepared to catch the
spray with a shop rag.
HINT:
This operation releases the lock pin for the most retard angle
lock.
(e) Under the condition above, turn the VVT-i to the advance
angle side (the direction of the white arrow in the illustra-
tion) by hand.
Standard: Must turn
HINT:
Depending on the air pressure, the VVT-i will turn to the ad-
vance angle side without applying force by hand. Also, if the
pressure can be hardly applied because of the air leakage from
the port, the lock pin might not be released easily.

(f) Check that the VVT-i moves freely within about 30
range. Avoid moving the VVT-i unit to the most retard
angle position as the lock pin will engage again.
Standard: Smooth movable range is about 30
(g) Turn the VVT-i by hand, then lock it at the most retard
angle position.
32. REMOVE CAMSHAFT TIMING GEAR ASSY
NOTICE:
Do not remove or install the camshaft timing gear (VVT-i)
unless you are replacing the VVT-i or camshaft.
(a) Clamp the camshaft in a vise on the hexagonal lobe.
NOTICE:
Be careful not to damage the camshaft.
(b) Using a 46 mm socket wrench, remove the lock nut by
turning it clockwise.
NOTICE:

Remove it with the lock pin engaged and locked at the
most retard angle position.

The lock nut has LH threads.

Never use any tools other than the socket wrench.
Other tools will deform the cam angle rotor.
(c) Remove the camshaft VVT-i.
NOTICE:
Never remove the 3 bolts on the gear.
If it is difficult to remove VVT-i, tap it lightly using a plastic-faced
hammer, then remove it.
33. REMOVE CAMSHAFT SUB GEAR
(a) Clamp the camshaft in a vise on the hexagonal lobe.
NOTICE:
Be careful not to damage the camshaft.

51. REMOVE OIL PUMP SEAL
(a) Using a screwdriver, pry out the oil seal.
52. REMOVE SPARK PLUG TUBE GASKET
(a) Bend up the tab on the ventilation baffle plate which pre-
vents the gasket from slipping out.
NOTICE:
Be careful not to damage the baffle plate of the cylinder
head cover.
(b) Using a screwdriver and hammer, tap out the gasket.
(c) Using needle-nose pliers, pry out the gasket.
NOTICE:
Be careful not to damage the cylinder head cover.
53. INSPECT TIMING BELT
NOTICE:

Do not bend, twist or turn the timing belt inside out.

Do not allow contact of the timing belt with oil, water
or steam.

Do not use the timing belt tension when installing or
removing the mounting bolt of the camshaft timing
pulley.
Check the belt for any defects as shown in the illustrations.
Also, check these points below.
(a) If the belt tears in a short time:

Check if the belt is installed properly.

Check if the timing cover gasket is damaged and if
it is installed properly.
(b) If the belt teeth are cracked or damaged, check if either
camshaft is locked.
(c) If there is noticeable wear or cracks on the belt face,
check if there are nicks on the side of the idler pulley lock
and water pump.

(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.
