(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)

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
