d. 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.
e. After all bolts tightened, retighten them to the specified torque in numerical order as shown in the figure.
5. Install two mounting bolts in front of oil pan (upper) in numerical
order as shown in the figure.
6. Install oil pan (lower). Refer to EM-26, "
OIL PAN AND OIL STRAINER" .
7. Install right and left valve timing control covers as follows.
a. Install new seal rings (1) in shaft grooves.
CAUTION:
When replacing seal ring, 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.M10 bolts : 1, 2, 3, 4, 5, 6, 7

c. Install valve timing control cover with new gasket 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 bolt are tightened, tighten No.1 bolt to the specified torque again.
8. 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).
9. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns
smoothly.
10. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluid leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
RECOMMENDED FLUIDS AND LUBRICANTS" . : 11.3 N·m (1.2 kg-m, 8 ft-lb)

Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.

Warm up engine thoroughly to make sure there is no leakage of exhaust gases, or any oil/fluids including
engine oil and engine coolant.

Bleed air from lines and hoses of applicable 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.

b. Shaft is engaged with intake side camshaft sprocket center hole
on inside. Pull straight out so as not to tilt until the joint is disen-
gaged.

The mating surface of magnet retarder may be fitted with the
exhaust side camshaft sprocket via the engine oil. Open valve
timing control cover carefully.

If the mating surface of magnet retarder is fitted with the cam-
shaft sprocket, open the cover within the range that the load is
not applied to the harness. And then, remove it so as to pre-
vent magnet retarder from dropping.
CAUTION:

Be careful not to damage magnet retarder.

When carrying valve timing control cover, face the magnet retarder side up to prevent the cover
from falling from magnet retarder.

Do not remove magnet retarder from valve timing control cover. (Disassembly prohibited parts)
8. Remove rocker covers (right and left banks). Refer to EM-40, "
ROCKER COVER" .
9. Obtain No. 1 cylinder at TDC of its compression stroke as follows:
a. Rotate crankshaft pulley clockwise to align timing mark (grooved
line without color) with timing indicator.
b. Make sure that intake and exhaust cam noses on No. 1 cylinder
(engine front side of right bank) are located as shown in the fig-
ure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.
10. Remove crankshaft pulley as follows:
a. Remove rear cover plate and set ring gear stopper [SST:
KV10118600 (J-48641)] (A) as shown in the figure.
