PRECAUTIONS

CAUTION:

Do not use home heating oil, gasoline or other alternate fuels in your diesel engine. The use of
those can cause engine damage.

Do not use summer fuel at temperatures below –7°C (20°F). The cold temperatures will cause wax
to form in the fuel. As a result, it may prevent the engine from running smoothly.

Do not add gasoline or other alternate fuels to diesel fuel.
Precautions for Multiport Fuel Injection System or Engine Control SystemEAS000FT

Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.

Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.

Be careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Turbocharger (If Equipped)EAS000FU
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean sup-
ply of oil flowing through the turbocharger and to follow all required
maintenance instructions and operating procedures.

Always use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.

Avoid accelerating engine to a high rpm immediately after start-
ing.

If engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting if off.
Precautions for HosesEAS000FV
HOSE REMOVAL AND INSTALLATION

To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.

To reinstall the rubber hose securely, make sure that hose inser-
tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)

DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00KN7
WARNING:
Be sure to perform this step when the engine is stopped.

Make sure that the indicator (single line notch on fixed side) of drive belt auto-tensioner is within the pos-
sible use range (between three line notches on moving side).
NOTE:

Check the drive belt auto-tensioner indicator (single line notch on fixed side) when engine is cold.

When new drive belt is installed, the indicator (single line notch on fixed side) should be within the
range “A” in the figure.

Visually check entire belt for wear, damage or cracks.

If the indicator (single line notch on fixed side) is out of the possible use range or belt is damaged, replace
drive belt.
Tension AdjustmentEBS00KN8
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationEBS00KN9
REMOVAL
1. Remove splash guard on RH undercover.
2. With box wrench, and while securely holding the hexagonal part
in center of drive belt auto-tensioner pulley, move the wrench
handle in the direction of arrow (loosening direction of ten-
sioner).
CAUTION:
Avoid placing hand in a location where pinching may occur
if the holding tool accidentally comes off.
3. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole of the retaining boss to fix
drive belt auto-tensioner pulley.
4. Loosen drive belt from water pump pulley in sequence, and
remove it.

ley, move the wrench handle in the direction of arrow (loosening direction of tensioner).
CAUTION:

2. Insert a rod approximately 6 mm (0.24 in) in diameter such as short-length screwdriver into the hole of
retaining boss to fix drive belt auto-tensioner pulley.
3. Hook drive belt onto all pulleys except for water pump, and then onto water pump pulley finally.
CAUTION:
Confirm belt is completely set to pulleys.
4. Release drive belt auto-tensioner, and apply tension to drive belt.
5. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
6. Confirm tension of drive belt at indicator is within the range of possible use. Refer to EM-13, "
Checking

CYLINDER BLOCK


Main bearing with an oil hole and groove goes on cylinder
block. The one without them goes on lower cylinder block.

Only main bearing (on cylinder block) for No. 3 journal has dif-
ferent specifications.

Before installing main bearings, apply new engine oil to the
bearing surface (inside). Do not apply new engine oil to the
back surface, but thoroughly clean it.

When installing, align main bearing stopper to the notch.

Ensure the oil holes on cylinder block and those on the corre-
sponding bearing are aligned.
4. Install signal plate to crankshaft if removed.
a. Position crankshaft and signal plate using a dowel pin, and
tighten mounting bolts.
b. Remove dowel pin.
CAUTION:
Be sure to remove dowel pin.
NOTE:
Dowel pin of crankshaft and signal plate is provided as a set for
each. If dowel pin is not available (when reusing crankshaft and
signal), use M6 bolt [length 10 mm (0.39 in) or more] as a substi-
tute.
5. Install crankshaft to cylinder block.

While turning crankshaft by hand, make sure that it turns smoothly.
6. Install lower cylinder block with the following procedure:
a. Apply liquid gasket with a tube presser (special service tool:
WS39930000) to lower cylinder block as shown in the figure.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
After liquid gasket is applied, rear oil seal installation must
be finished within 5 minutes. Therefore, the following pro-
cedure must be performed quickly.
NOTE:
Lower cylinder block cannot be replaced as a single part,
because it is machined together with cylinder block.
b. Tighten lower cylinder block mounting bolts with the following
procedure:
i. Apply new engine oil to threads and seat surfaces of mounting bolts.
ii. Tighten M8 bolts in numerical order from No. 11 to 22 in the fig-
ure.
NOTE:
There are more processes to complete the tightening of mount-
ing bolts. However stop procedure here to install rear oil seal.
c. Install rear oil seal. Refer to EM-65, "
Removal and Installation of Rear Oil Seal" .
d. Restart tightening of lower cylinder block mounting bolts with the following procedure:
