Torque: 5.4 Nm (55 kgf-cm, 48 inch lbs.)
NOTICE: Do not 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.
29. INSTALL CAMSHAFT TIMING GEAR ASSY
a) Align the alignment pin with the alignment pin groove and install the VVT-i on the camshaft.
NOTICE: Install the VVT-i with the lock-pin engaged and locked at the most retarded angle position.

30. INSTALL NO.2 CAMSHAFT
NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be held level while it is being installed. If the camshaft is not level, the portion of the cylinder head receiving the shaft thrust may crack or be damaged, causing the camshaft to seize or break. To avoid this, the following steps must be carried out.
a) Apply new engine oil to the thrust portion and journal of the camshaft.

^ Insert the oil seal until it cannot be pushed any further.
e) Remove any old packing material from the contact surface.
f) Apply seal packing to the No. 1 bearing cap as shown in the illustration.
Seal packing: Part No. 08826-00080 or equivalent
NOTICE:
^ Install the No. 1 bearing cap within 5 minutes after applying seal packing.
^ Do not expose the seal to engine oil for at least 2 hours after installing.
g) Install the 5 bearing caps in their proper locations.
h) Apply a light coat of engine oil on the threads of the bearing cap bolts.
i) Uniformly tighten the 10 bearing cap bolts in the sequence shown in the illustration.
Torque: 16 Nm (163 kgf-cm, 12 ft. lbs.)
31. INSTALL CAMSHAFT
NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be held level while it is being installed. If the camshaft is not level, the portion of the cylinder head receiving the shaft thrust may crack or be damaged, causing the camshaft to seize or break. To avoid this, the following steps must be carried out.
a) Apply new engine oil to the thrust portion and journal of the camshaft.
b) Align the camshaft drive and driven gear's timing marks (2 dot marks each).
c) Place the camshaft on the cylinder head.
d) Install the 5 bearing caps in their proper locations.
