90. INSTALL TIMING BELT TENSIONER ASSY
(a) Set the timing belt tensioner upright on the press.
(b) Slowly press in the push rod.
NOTICE:
Do not apply pressure more than 9.8 kN (1,000 kgf, 2,205
lbf) to the rod.
(c) Align the holes of the push rod and housing, then pass a
1.5 mm hexagon wrench through the holes to keep the
setting position of the push rod.
(d) Release the press.
(e) Temporarily install the tensioner with the 2 bolts. Alter-
nately tighten the 2 bolts.
Torque: 27 NVm (280 kgfVcm, 20 ftVlbf)
NOTICE:
Be sure to tighten the bolts uniformly. Installing the ten-
sioner at an angle may cause failure of its proper operation.
(f) Remove the 1.5 mm hexagon wrench from the tensioner.
(g) Turn the crankshaft 2 revolutions slowly, then align the
timing mark of the crankshaft timing pulley with the oil
pump body.
NOTICE:
Always turn the crankshaft clockwise.
(h) Check that the timing marks of the RH and LH timing pul-
leys are aligned with the timing marks of the timing belt
No. 3 cover as shown in the illustration.
If the marks are not aligned, remove the timing belt and reinstall
it.
(i) Remove the crankshaft pulley bolt.
91. INSTALL TIMING BELT GUIDE NO.2
(a) Install the timing belt guide with the cup side facing the en-
gine front.

(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.
(e) Remove the timing belt in this order.

27. REMOVE NO.2 CAMSHAFT
(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. 2 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. 2 camshaft.
28. 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.

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.

(e) Using SST, align the holes of the camshaft main gear and
sub gear by turning the camshaft sub gear counterclock-
wise, then temporarily install a service bolt.
SST 09960-10010 (09962-01000, 09963-00500)
(f) Align the gear teeth of the main gear and sub gear, then
tighten the service bolt.
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
NOTICE:
Be careful not to damage the camshaft journals.
HINT:
When installing the camshaft, make certain that the torsional
spring force of the sub gear has been eliminated by installation
of the service bolt.
31. INSTALL CAMSHAFT TIMING GEAR ASSY
(a) Align the alignment pin with the alignment pin groove,
then install the VVT-i on the camshaft.
NOTICE:
Install it with the lock pin engaged and locked at the most
retard angle position.
(b) Apply engine oil to the nut, mounting surface of the VVT-i
and screw threads.
NOTICE:
Be sure to apply the oil, otherwise the specified
torque cannot be obtained.
New nut must be used when replacing the VVT-i unit.
(c) Using a 46 mm socket wrench, install and tighten a lock
nut by turning it counterclockwise.
Torque: 150 NVm (1,530 kgfVcm, 111 ftVlbf)
NOTICE:
The lock nut has LH threads.
Never use any tools other than the socket wrench.
Other tools will deform the cam angle rotor.
32. INSTALL NO.2 CAMSHAFT
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.
