tions marked “×” as shown in the table below (locations indi-
cated with black arrow in figure).

c. Rotate crankshaft pulley clockwise (when view from engine
front) by 270 degrees from the position of No. 1 cylinder com-
pression TDC to align No. 3 cylinder at TDC of its compression
stroke.
NOTE:
Crankshaft pulley mounting bolt flange has a angle mark every
90 degrees. They can be used as a guide to rotation angle.

4. For measured value are out of the standard, perform adjustment. Refer to EM-217, "
ADJUSTMENT" .
ADJUSTMENT
CAUTION:

Adjust valve clearance while engine is cold.

After adjusting, make sure that the valve clearance is within the standard while engine is hot.
1. Thoroughly wipe off engine oil around adjusting shim using rag.
2. Rotate crankshaft to position cam nose on camshaft of valve that must be adjusted upward.
3. Using small screwdriver, turn the round hole of adjusting shim in
the direction of the arrow.
CAUTION:
perform (the above procedure) during camshaft do not con-
tact with adjusting shim.
4. Install lifter stopper [SST: 10115120 (J38972-2)] as follows:
a. Except exhaust side of No. 7 and No. 8 cylinder;
i. Place camshaft pliers (SST) around camshaft as shown in the
figure.
ii. Rotate camshaft pliers so that valve lifter is pushed down.
CAUTION:
Be careful not to damage cam surface, valve lifter and cylin-
der head with camshaft pliers.

iii. Place lifter stopper between camshaft and the edge of valve
lifter to retain valve lifter.
CAUTION:

Lifter stopper must be placed as close to camshaft
bracket as possible.

Be careful not to damage cam surface, valve lifter and
cylinder head with lifter stopper.
iv. Remove camshaft pliers.
CAUTION:
Camshaft pliers should be removed by rotating it slowly
because lifter stopper hits and damages journal portion by
rotating camshaft pliers quickly.
b. Exhaust side of No. 7 and No. 8 cylinder;
NOTE:
Exhaust side of No. 7 and No. 8 cylinder does not have space for installing camshaft pliers [SST:
KV10115110 (J38972-1)]. therefore, install lifter stopper [SST: KV10115120 (J38972-2)] according to the
following instructions.
i. Rotate crankshaft to press cam nose to the adjusting part of valve lifter.
ii. Place lifter stopper between camshaft and the edge of valve lifter to retain valve lifter.
CAUTION:

Lifter stopper must be placed as close to camshaft bracket as possible.

Be careful not to damage cam surface, valve lifter and cylinder head with lifter stopper.
iii. Rotate crankshaft slowly 180 degrees clockwise.
CAUTION:
Rotating crankshaft slowly because lifter stopper hits and damages journal portion by rotating
crankshaft quickly.
5. Blow air into the round hole to separate adjusting shim from
valve lifter.
CAUTION:
When blowing, use goggles to protect your eye.
6. Remove adjusting shim with magnetic hand.
7. Use the equation below to calculate adjusting shim thickness for replacement.

Rotate crankshaft slowly 180 degrees clockwise. then remove lifter stopper.
10. Manually rotate crankshaft pulley a few turns.
11. Make sure that the valve clearance is within the standard.
12. Make sure again that the valve clearance for hot engine is within specifications by referring to the speci-
fied values.

Crankshaft key should line up with the left 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 are re-used, check their outer diame-
ters before installation. Refer to EM-226, "
Cylinder Head
Bolts Outer Diameter" .
a. Apply engine oil to threads and seating surface of cylinder head
bolts.
b. Tighten all bolts. 98.1 N·m (10 kg-m, 72 ft-lb).
c. Completely loosen all bolts.
CAUTION:
In step “c”, loosen bolts in reverse order of that indicated in the figure.
d. Tighten all bolts to 44.1 N·m (4.5 kg-m, 33 ft-lb).
e. Turn all bolts 60 degrees clockwise. (Angle tightening)
CAUTION:
Check and confirm the tightening angle by using angle
wrench (SST) and cylinder head bolt wrench (commercial
service tool). Avoid judgment by visual inspection without
SST.
f. Turn all bolts 60 degrees clockwise again. (Angle tightening)
4. Install in the reverse order of removal after this step.

Press-fit pilot converter with its chamfering side facing crank-
shaft as shown in the figure.

It is possible to remove pilot converter without hoisting engine
with engine stand.
5. Install crankshaft to cylinder block.

While turning crankshaft by hand, make sure it turns smoothly.
6. Install main bearing caps.

Align the identification number to the journal position to install.

Install the upper side of the identification number facing the
front of engine. (The number shall be read correctly from the
rear of engine.)

Using plastic hammer or similar tool, tap them lightly to seat
them on the installation position.
NOTE:
Main bearing cap cannot be replaced as a single parts, because
it is machined together with cylinder block.
7. Install each main bearing cap bolt as follows:
a. Apply new engine oil to threads and seating surface of main
bearing cap bolts, and tighten all bolts temporarily.
b. Tighten main bearing cap bolt (M12) in order of 1 to 10.
c. Tighten main bearing cap sub bolt (M9) in order of 11 to 20.
d. Tighten main bearing cap bolt (M12) to 40 degrees clockwise in
order of 1 to 10. (Angle tightening)
CAUTION:
Use angle wrench (SST) to check tightening angle in step
“d” and “e”. Do not make judgment by visual inspection.
e. Tighten main bearing cap sub bolt (M9) to 30 degrees clockwise
in order of 11 to 20. (Angle tightening)
f. Tighten side bolt (M10) in order of 21 to 30.

After installing main bearing cap bolts, make sure that crankshaft can be rotated smoothly.

Check the crankshaft end play. Refer to EM-256, "CRANKSHAFT END PLAY" .
