(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.

(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.
75. INSTALL CAMSHAFT TIMING GEAR ASSY
(a) Align the alignment pin with the alignment pin groove,
then install the VVT-i into 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.

Other tools will deform the cam angle rotor.
76. 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
