(b) Check that the timing marks of the camshaft timing 

gears are aligned with the timing marks of the 
bearing caps as shown in the illustration.
If not, turn the crankshaft 1 complete revolution 
(360

°) and align the timing marks above.

(c) Place paint marks on the No. 1 chain links 

corresponding to the timing marks of the camshaft 
timing gears.

14. REMOVE NO. 1 CHAIN TENSIONER ASSEMBLY

NOTICE:
•

Never rotate the crankshaft with the chain 
tensioner removed.

•

When rotating the camshaft with the timing chain 
removed, rotate the crankshaft counterclockwise 
40

° from the TDC first.

(a) Remove the 4 bolts, then remove the timing chain 

cover plate and gasket.

(b) While turning the stopper plate of the tensioner 

upward, push in the plunger of the chain tensioner 
as shown in the illustration.

(c) While turning the stopper plate of the tensioner 

downward, insert a bar of 

φ3.5 mm (0.138 in.) into 

the holes in the stopper plate and tensioner to fix the 
stopper plate.

(d) Remove the 2 bolts, then remove the chain 

tensioner.

15. REMOVE 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 
steps to avoid such problems.

(a) While raising the chain tensioner No. 2, insert a pin 

of 

φ1.0 mm (0.039 in.) into the hole to fix it.

(b) Hold the hexagonal portion of the No. 2 camshaft 

with a wrench, and remove the camshaft timing gear 
set bolt.
NOTICE:
Be careful not to damage the cylinder head or 
valve lifter with the wrench.

(c) Separate the camshaft timing gear from the No. 2 

camshaft.

(d) Rotate the camshaft counterclockwise using the 

wrench so that the cam lobes of No. 1 cylinder face 
upward as shown in the illustration.

(e) Using several steps, uniformly loosen and remove 

the 8 bearing cap bolts in the sequence shown in 
the illustration.

(f)

Remove the 4 bearing caps and No. 2 camshaft.

16. REMOVE NO. 2 CHAIN TENSIONER ASSEMBLY

(a) Remove the No. 2 chain tensioner bolt, then remove 

the No. 2 chain tensioner and camshaft timing gear.

17. REMOVE 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) Hold the hexagonal portion of the No. 1 camshaft 

with a wrench, and loosen the camshaft timing gear 
set bolt.
NOTICE:
•

Be careful not to damage the cylinder head or 
valve lifter with the wrench.

•

Do not disassemble the camshaft timing gear 
assembly.

(b) Slide the camshaft timing gear and separate the No. 

1 chain from the camshaft timing gear.

(c) Rotate the No. 1 camshaft counterclockwise using 

the wrench so that the cam lobes of No. 1 cylinder 
face downward as shown in the illustration.

(d) Using several steps, loosen and remove the 8 

bearing cap bolts in the sequence shown in the 
illustration.

(e) Remove the 4 bearing caps.

(f)

Remove the camshaft timing gear set bolt with the 
No. 1 camshaft lifted up, then remove the No. 1 
camshaft and camshaft timing gear with No. 2 
chain.

(g) Tie the No. 1 chain with a piece of string as shown 

in the illustration.
NOTICE:
Be careful not to drop anything inside the timing 
chain cover.

18. REMOVE 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 
camshaft to seize or break. Perform the following 
steps to avoid such problems.

(a) While pushing down the No. 3 chain tensioner, 

insert a pin of 

φ 1.0 mm (0.039 in.) into the hole to fix 

it.
