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

CAUTION:
Do not overtighten slack guide mounting bolts. It is normal
for a gap to exist under the bolt seats when mounting bolts
are tightened to specification.
9. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab up (or turn lever downward) so as to
remove plunger stopper tab from the ratchet of plunger.
NOTE:
Plunger stopper tab and lever are synchronized.
b. Push plunger into the inside of tensioner body.
c. Hold plunger in the fully compressed position by engaging
plunger stopper tab with the tip of ratchet.
d. To secure lever, insert stopper pin through hole of lever into ten-
sioner body hole.

The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.
e. Install timing chain tensioner (primary).

Remove any dirt and foreign materials completely from the
back and the mounting surfaces of timing chain tensioner (pri-
mary).
f. Pull out stopper pin after installing, and then release plunger.
10. Make sure again that the mating marks on sprockets and timing chain have not slipped out of alignment.
11. Install new O-ring (1) on rear timing chain case.
12. Install new front oil seal on front timing chain case.

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.

Using suitable drift (1), press-fit oil seal until it becomes flush
with front timing chain case end face.

Make sure the garter spring is in position and seal lip is not
inverted.
13. Install front timing chain case as follows:
a. Apply a continuous bead of liquid gasket with tube presser [SST:
WS39930000 ( — )] to front timing chain case back side as
shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-45, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
NOTE:
Apply liquid gasket, start and end up application at the portions
(a) shown in the figure.
b. Install front timing chain case as to fit its dowel pin hole together dowel pin on rear timing chain case.

c. Tighten mounting bolts to the specified torque in numerical order
as shown in the figure.

There are two types of mounting bolts. Refer to the following
for locating bolts.
d. After all bolts are tightened, retighten them to the specified
torque in numerical order shown in the figure.
CAUTION:
Be sure to wipe off any excessive liquid gasket leaking on surface mating with oil pan (upper).
e. After installing front timing chain case, check the surface height
difference between the following parts on the oil pan (upper)
mounting surface.

If not within standard, repeat the installation procedure.
14. Install right and left valve timing control covers as follows:
a. Install new seal rings (1) in shaft grooves.
CAUTION:
When replacing seal rings, replace all rings with new one.
b. To check the joint between dowel pins and dowel pin holes,
check the looseness in the axle direction by pushing the mating
surface of magnet retarder (A) at several places and the circum-
ferential looseness (between dowel pins and dowel pin holes) by
twisting in the circumferential direction.
CAUTION:
Always perform this procedure when removing because the
gap between dowel pins and dowel pin holes may not be
caused on purpose.M8 bolts : 1, 2, 3, 4, 5, 6, 7

c. Install valve timing control cover to front timing chain case.
CAUTION:

Do not face the magnet retarder side down to prevent
magnet retarder from dropping.

Check the mating surface of magnet retarder and the
drum of exhaust side camshaft sprocket for foreign mate-
rials.

Align the center of both shaft holes of the shaft and the
intake side camshaft sprocket, and then insert them.

Be careful not to drop the seal ring from the shaft groove.

When setting the valve timing control cover in position
by hand, if valve timing control cover is not contacting with the front timing chain case, the
dowel pin of magnet retarder may not be aligned with the dowel pin holes of cover. In this case,
return to step “b”.
d. Tighten mounting bolts in numerical order as shown in the fig-
ure.
CAUTION:
Completely tighten the mounting bolts with the seat surface
of valve timing control cover contacting with front timing
chain case.

After all bolts are tightened, tighten No.1 bolt to the specified torque again.
15. Install oil pans (upper and lower). Refer to EM-26, "
OIL PAN AND OIL STRAINER" .
16. Install rocker covers (right and left banks). Refer to EM-40, "
ROCKER COVER" .
17. Install crankshaft pulley as follows:
a. Fix crankshaft using ring gear stopper [SST: KV10118600 (J-48641)].
b. Install crankshaft pulley, taking care not to damage front oil seal.

When press-fitting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
c. Tighten crankshaft pulley bolt.
d. Place a paint mark (A) on crankshaft pulley (2) aligning with the
angle mark (C) on crankshaft pulley bolt (1). Tighten the bolt 90
degrees (one marks) (b).
18. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns
smoothly.
