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 onsurface.
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 (thelarger 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 ar e aligned, keep them aligned by holding them
with a hand.
Install slack guides and tension guides onto correct si de by checking with identification mark on surface.
Install chain tensioner with plunger fixed as described in its removal.
CAUTION:
Before and after the installation of chain tens ioner, make sure that the mating mark on timing
chain is not out of alignment.
After installing chain tensioner, remove stoppe r 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-29
.
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.

TIMING CHAIN
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak. Before starting engine, check oil/fluid levels incl
uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-9, "
Fluids and Lubricants"
Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
Bleed air from lines and hoses of applic able lines, such as in cooling system.
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

CAMSHAFT
3. With hexagonal part of camshaft locked with wrench, loosen
bolts securing camshaft sprocket to remove camshaft sprocket.
CAUTION:
Do not loosen mounting bol ts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike the piston head.
4. Remove intake and exhaust camshaft brackets. Mark camshafts, camshaft brackets and bolts so placed in the same position and direction for installa-
tion.
Equally loosen camshaft brackets and bolts in several steps in reverse order as shown in the figure.
Lightly tapping with plastic hammer, remove camshaft bracket (No. 1) and camshaft bracket (No. 6).
NOTE:
The bottom surface of each bracket will be stuck to cylinder
head because of liquid gasket.
5. Remove camshaft.
6. Remove valve lifter if necessary. Identify installation positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journalof camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft
sprocket) because it has a differe nt diameter from the other
four locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
