(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.
