In this figure, the drum of exhaust side camshaft sprocket has been omitted.
1. Install timing chain tensioners (secondary) to cylinder head as follows if removed. Refer to EM-77,
"INSTALLATION" .
a. Install timing chain tensioners (secondary) with stopper pin attached and new O-ring.
b. Install camshaft brackets (No. 1). Refer to EM-77, "
INSTALLATION" .
2. Measure difference in levels between front end faces of cam-
shaft bracket (No.1) and cylinder head.

Measure two positions (Both intake and exhaust side) for a
single bank.

If the measured value is out of the standard, re-install cam-
shaft bracket (No.1).
3. Install rear timing chain case as follows:
1. Internal chain guide 2. Camshaft sprocket (INT) 3. Timing chain (secondary)
4. Camshaft sprocket (EXH) 5. Timing chain tensioner (primary) 6. Slack guide
7. Timing chain (primary) 8. Crankshaft sprocket 9. Water pump

c. Align rear timing chain case and water pump assembly with dowel pins (right and left) on cylinder block
and install rear timing chain case.

Make sure O-rings stay in place during installation to cylinder block.
d. Tighten mounting bolts in numerical order as shown in the fig-
ure.

There are two types of mounting bolts. Refer to the following
for locating bolts.
e. After all bolts are tightened, retighten them to the specified in
numerical order shown in the figure.

If liquid gasket protrudes, wipe it off immediately.
f. After installing rear timing chain case, check the surface height
difference between following parts on oil pan (upper) mounting
surface.

If not within standard, repeat the installation procedure.
4. Install water pump with new O-rings. Refer to CO-23, "
WATER PUMP" .
5. Make sure that dowel pin (A) and crankshaft key (1) 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.
6. Install timing chains (secondary) and camshaft sprockets as follows:
CAUTION:

When replacing camshaft sprocket (EXH), replace valve timing control cover (including magnet
retarder and cover).

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

INSTALLATION
1. Install timing chain tensioners (secondary) (1) on both sides of
cylinder head.

Install timing chain tensioner with its stopper pin (C) attached.

Install timing chain tensioner with sliding part facing down-
ward on right-side cylinder head, and with sliding part facing
upward on left-side cylinder head.
2. Install valve lifter.

Install it in the original position.
3. Install camshafts.

Follow your identification marks made during removal, or fol-
low the identification marks that are present on new cam-
shafts for proper placement and direction.

Install camshaft so that and dowel pin (A) on front end face
are positioned as shown in the figure. (No. 1 cylinder TDC on
its compression stroke)
NOTE:
Though camshaft does not stop at the portion 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. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.

If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gaskets.
2. Turn crankshaft until No. 1 piston is set at TDC.

Crankshaft key should line up with the right bank cylinder cen-
ter line as shown in the figure.
3. Install cylinder head follow the steps below to tighten cylinder
head bolts in numerical order as shown in the figure.
CAUTION:
If cylinder head bolts re-used, check their outer diameters
before installation. Refer to EM-91, "
Cylinder Head Bolts
Outer Diameter" .
a. Apply new engine oil to threads and seat surfaces of cylinder
head bolts.
b. Tighten all cylinder head bolts.
c. Completely loosen all cylinder head bolts.
CAUTION:
In step “c”, loosen bolts in reverse order of that indicated in
the figure.
d. Tighten all cylinder head bolts.Limit : 0.1 mm (0.004 in)
