(f)

Hold the hexagonal portion of the No. 4 camshaft
with a wrench, and tighten the camshaft timing gear
set bolt.
Torque: 100 N*m (1,020 kgf*cm, 74 ft.*lbf)

(g) Remove the pin from the No. 3 chain tensioner.

(h) Release the chain tension between the camshaft

timing gear (bank 1) and crankshaft timing gear by
turning the crankshaft pulley clockwise slightly.

INSTALL CAMSHAFT
NOTICE:
Keep the camshaft level while it is being removed.
The camshaft thrust clearance is very small and
failing to keep it level could crack or damage the
cylinder head journal surface, which receives the
thrust force. This could subsequently lead the
camshaft to seize or break. Perform the following
steps to avoid such problems.

(a) Align the yellow mark link with the timing mark (1 dot

mark) of the camshaft timing gear as shown in the
illustration.

(b) Apply new engine oil to the thrust portion and

journal of the camshafts.

(c) Temporarily install the No. 1 chain onto the No. 2

chain of the camshaft timing gear.

(d) Align the knock pin hole in the camshaft timing gear

with the knock pin of the No. 1 camshaft, and insert
the No. 1 camshaft into the camshaft timing gear.

(e) Temporarily install the camshaft timing gear set bolt.

(f)

Install the No. 1 camshaft onto the bank 1 cylinder
head with the cam lobes of the No. 1 cylinder facing
downward as shown in the illustration.

(g) Install the 4 bearing caps in the proper locations as

shown.

(h) Apply a light coat of engine oil to the threads and

under the heads of the bearing cap bolts.

(i)

Using several steps, uniformly install and tighten the
8 bearing cap bolts in the sequence shown in the
illustration.
Torque: 10 mm (0.39 in.) head

9.0 N*m (92 kgf*cm, 80 in.*lbf)
12 mm (0.47 in.) head
24 N*m (245 kgf*cm, 18 ft.*lbf)

(j)

Rotate the No. 1 camshaft clockwise using a wrench
so that the timing mark of the camshaft timing gear
is aligned with the timing mark of the camshaft
bearing cap.

(k) Align the paint mark of the No. 1 chain with the

timing mark of the camshaft timing gear.

(l)

Hold the hexagonal portion of the No. 1 camshaft
with a wrench, and tighten the camshaft timing gear
set bolt.
Torque: 100 N*m (1,020 kgf*cm, 74 ft.*lbf)

5.

INSTALL NO. 2 CHAIN TENSIONER ASSEMBLY
(a) While pushing in the tensioner, insert a pin of

φ 1.0

mm (0.039 in.) into the hole to fix it.

(b) Temporarily install the camshaft timing gear and No.

2 chain tensioner and align the yellow mark links
with the timing marks (1 dot mark) of the camshaft
timing gears.

(c) Tighten the No. 2 chain tensioner bolt.

Torque: 19 N*m (194 kgf*cm, 14 ft.*lbf)

INSTALL NO. 2 CAMSHAFT
NOTICE:
Keep the camshaft level while it is being removed.
The camshaft thrust clearance is very small and
failing to keep it level could crack or damage the
cylinder head journal surface, which receives the
thrust force. This could subsequently lead the
camshaft to seize or break. Perform the following
