25. REMOVE TIMING BELT NO.3 COVER
(a) Disconnect the 3 engine wire harness clamps from the
timing belt No. 3 cover.
(b) Remove the 6 bolts and timing belt cover.
26. REMOVE CAMSHAFT
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while being removed. 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) Align the timing marks (2 dot marks) of the camshaft drive
and driven gears by turning the camshaft with a wrench.
(b) Secure the exhaust camshaft sub gear to the main gear
with a service bolt.
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
Recommended service bolt
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 to 20 mm
HINT:
When removing the camshaft, make certain that the torsional
spring force of the sub gear has been eliminated by installation
of the service bolt.
(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 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) 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.

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.
