(5) When the camshaft timing gear comes to the 

most advanced position, release the 
compressed air on the timing retard side path, 
and release that on the timing advance side 
path.
NOTICE:
Camshaft timing assembly gear 
occasionally shifts to the retard side 
abruptly if the air compression on the 
advanced side path is released first. This 
often causes breakage of the lock pin.

(e) Check the smooth revolution.

(1) Rotate the camshaft timing gear several times 

within the movable range except for the most 
retarded position and check it rotates smoothly.
Standard:

Moves smoothly in a range of about 31

°

NOTICE:
Be sure to perform this check by hand, 
instead of using compressed air.

(f)

Check that the lock is in the most retarded position.
(1) Confirm that the camshaft timing gear 

assembly is locked in the most retarded 
position.

(g) Remove the set bolt, then remove the camshaft 

timing gear assembly.
NOTICE:
Do not remove the other 3 bolts.

INSTALLATION

1.

INSTALL NO. 3 CAMSHAFT SUB-ASSEMBLY
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 (2 dot 

marks) 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 put the No. 1 chain on 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. 3 camshaft, and insert 
the No. 3 camshaft into the camshaft timing gear.

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

(f)

Set the No. 3 camshaft onto the bank 2 cylinder 
head with the cam lobes of the No. 2 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.

24 N*m (245 kgf*cm, 18 ft.*lbf)

(j)

Align the paint mark of the No. 1 chain with the 
timing marks of the camshaft timing gear.

(k) Hold the hexagonal portion of the No. 3 camshaft 

with a wrench, and tighten the camshaft timing gear 
set bolt.
Torque: 100 N*m (1,020 kgf*cm, 74 ft.*lbf)

2.

INSTALL NO. 3 CHAIN TENSIONER ASSEMBLY
(a) While pushing in the tensioner, insert a pin of 

φ 1.0 

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

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

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

(c) Tighten the No. 3 chain tensioner bolt.

INSTALL NO. 4 CAMSHAFT SUB-ASSEMBLY
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

the No. 4 camshaft into the camshaft timing gear.

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

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

shown.

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