(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.

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.
41. INSTALL CYLINDER HEAD GASKET
(a) Place a new cylinder head gasket on the cylinder block
with the R mark upward.
NOTICE:

Remove any oil from the contact surface.

Be careful of the installing orientation.

Place the cylinder head on the gasket carefully in or-
der not to damage the gasket at the bottom part of the
head.
42. INSTALL CYLINDER HEAD SUB-ASSY
NOTICE:
The cylinder head bolts are tightened in 2 successive
steps.
(a) Apply a light coat of engine oil to the threads of the cylin-
der head bolts.
(b) Install the plate washers to the cylinder head bolts.
(c) Using several steps, install and tighten the 8 cylinder
head bolts uniformly in the sequence shown in the illustra-
tion.
Torque: 54 NVm (550 kgfVcm, 40 ftVlbf)
(d) Mark the front side of each cylinder head bolt head with
paint as shown in the illustration.
(e) Retighten the cylinder head bolts by 90in the same se-
