INSPECTION AFTER REMOVAL
Timing Chain
Check tor cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as necessary.
INSTALLATION
NOTE:
The above figure shows the relationship between the mating mark on each timing chain and that on the
corresponding sprocket, with the components installed.
Parts with an identification mark (R or L) should be installed on the corresponding bank according to the
mark.
Parts with an identification mark:
–Camshaft sprocket (INT)
–Dowel pin groove of camshaft sprocket (EXH) (camshaft sprocket is same part both banks)
–Chain tension guide
–Chain slack guide
To install timing chain and related parts, start with those on right bank. The procedure for installing parts
on left bank is omitted because it is the same as that for installation on right bank.

1. Make sure that crankshaft key and dowel pin of each camshaft
are located as shown in the figure. (No. 1 cylinder at compres-
sion 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.
2. Install camshaft sprockets.
Install onto correct side by checking with identification mark
on surface.
Install camshaft sprocket (EXH) by selectively using the
groove of dowel pin according to the bank. (Common part
used for both banks.)
Lock the hexagonal part of camshaft in the same procedure
as for removal, and tighten mounting bolts.
3. Install crankshaft sprockets for both banks.
Install each crankshaft sprocket so that its flange side (the
larger diameter side without teeth) faces in the direction
shown in the figure.
NOTE:
The same parts are used but facing directions are different.Camshaft dowel pin
: At cylinder head upper face side in each bank
Crankshaft key
: At cylinder head side of left bank

4. Install timing chains and related parts.
Align the mating mark on each sprocket and timing chain for installation.
NOTE:
Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for
that on each sprocket for alignment.
CAUTION:
For the above reason, after the mating marks are aligned, keep them aligned by holding them
with a hand.
Install slack guides and tension guides onto correct side by checking with identification mark on sur-
face.
Install chain tensioner with plunger fixed as described in its removal.
CAUTION:
Before and after the installation of chain tensioner, make sure that the mating mark on timing
chain is not out of alignment.
After installing chain tensioner, remove stopper pin to release tensioner. Make sure tensioner
is released.
To avoid chain-link skipping of timing chain, do not move crankshaft or camshafts until front
cover is installed.
5. Perform the same procedure as for right bank, install timing chain and related parts on left side.
6. Install oil pump. Refer to LU-30, "
OIL PUMP" .

7. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank-
shaft key and the two flat surfaces of oil pump inner rotor.
If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi-
tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
8. Install front oil seal on front cover.
Apply new engine oil to both oil seal lip and dust seal lip.
Install it so that each seal lip is oriented as shown in the fig-
ure.
CAUTION:
Be careful not to scratch or make burrs on circumference
of oil seal.
Using front oil seal drift (commercial service tool), press fit
until the height of front oil seal is level with the mounting sur-
face.
Make sure the garter spring is in position and seal lips not
inverted.
9. Install chain tensioner cover to front cover.
Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 ( — )] to front cover as shown in the
figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
10. Install front cover as follows:
