TIMING CHAIN

16. Remove internal chain guide, tension guide and slack guide.

NOTE:
Tension guide can be removed after removing timing chain (pri-
mary).

17. Remove timing chain (primary) and crankshaft sprocket.

CAUTION:

After removing timing chain (primary), never turn crankshaft and camshaft separately, or valves
will strike the piston heads.

18. Remove timing chain (secondary) and camshaft sprockets as follows:

a.

Attach a suitable stopper pin (B) to the bank 1 (A) and bank 2
(C) timing chain tensioners (secondary) (1).
NOTE:
• Use approximately 0.5 mm (0.02 in) dia. hard metal pin as a

stopper pin.

• For removal of timing chain tensioner (secondary), refer to

EM-84, "Exploded View"

. [Removing camshaft bracket (No. 1)

is required.]

b.

Remove camshaft sprockets (INT and EXH) mounting bolts.
• Secure the hexagonal portion of camshaft using a wrench to

loosen mounting bolts.

CAUTION:

Never loosen mounting bolts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.

c.

Remove timing chain (secondary) together with camshaft sprockets.
• Turn camshaft slightly to secure slackness of timing chain on timing chain tensioner (secondary) side.

• Insert 0.5 mm (0.020 in) thick metal or resin plate between tim-

ing chain and timing chain tensioner plunger (guide) (F).
Remove timing chain (secondary) (1) together with camshaft
sprockets with timing chain loose from guide groove.

CAUTION:

Be careful of plunger coming-off when removing timing chain (secondary). This is because
plunger of timing chain tensioner (secondary) moves during operation, leading to coming-off of
fixed stopper pin. 
NOTE:
• Camshaft sprocket (INT) is two-for-one structure of sprockets for timing chain (primary) and for timing

chain (secondary).

• Figure is shown as an example of bank 1.

• When handling camshaft sprocket (INT), be careful of the following caution:

CAUTION:

• Handle carefully to avoid any shock to camshaft sprocket.
• Never disassemble. [Never loosen bolts (A) as shown in

the figure].

19. Remove timing chain tensioners (secondary) from cylinder head as follows, if necessary.

• Remove timing chain tensioners (secondary) with a stopper pin attached.

20. Use a scraper to remove all traces of old liquid gasket from front

timing chain case, and opposite mating surfaces.

• Remove old liquid gasket from bolt hole (B) and thread.

INSTALLATION

NOTE:
The below figure shows the relationship between the mating mark on each timing chain and that on the corre-
sponding sprocket, with the components installed.

1.

Install timing chain tensioners (secondary) to cylinder head as follows if removed. Refer to 

EM-84,

"Exploded View"

.

• Install timing chain tensioners (secondary) with a stopper pin attached and new O-ring.

2.

Check that dowel pin hole, dowel pin and crankshaft key are
located as shown in the figure. (No. 1 cylinder at compression
TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.

CAUTION:

Hole on small dia. side must be used for intake side dowel pin hole. Never misidentify (ignore big
dia. side).

3.

Install timing chain (secondary) and camshaft sprockets (INT and EXH) as follows:

CAUTION:

Mating marks between timing chain and sprockets slip easily. Confirm all mating mark positions
repeatedly during the installation process.

a.

Push plunger of timing chain tensioner (secondary) and keep it
pressed in with stopper pin (A).

b.

Install timing chain (secondary) (1) and camshaft sprockets (INT
and EXH).

NOTE:
Figure shows bank 1 (rear view).
• Align the mating marks on timing chain (secondary) (orange

link) with the ones on camshaft sprockets (INT and EXH)
(punched), and install them.
NOTE:
• Mating marks for camshaft sprocket (INT) are on the back

side of camshaft sprocket (secondary).

• There are two types of mating mark, circle and oval types.

They should be used for the bank 1 and bank 2, respectively.

Camshaft dowel pin hole (intake side)

: At cylinder head upper face side in each bank

Camshaft dowel pin (exhaust side)

: At cylinder head upper face side in each bank

Crankshaft key

: At cylinder head side of bank 1
