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.)

INSTALLATION
1. With box wrench, and while securely holding the hexagonal part in pulley center of drive belt auto-ten-
sioner, move the wrench handle in the direction of arrow (loosening direction of tensioner).
CAUTION:
Avoid placing hand in a location where pinching may occur if the holding tool accidentally comes
off.
2. Insert a rod approximately 6 mm (0.24 in) in diameter into retaining boss to fix auto-tensioner pulley.
3. Hook drive belt onto all pulleys except for water pump. Hook drive belt onto water pump pulley at the end.
CAUTION:
Confirm belts are completely set to pulleys.
4. Release auto-tensioner, and apply tensions to belt.
5. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
6. Confirm tensions of belt at indicator is within the allowable use range. Refer to EM-12, "
Checking Drive
Belts" .
Removal and Installation of Drive Belt Auto-TensionerEBS00KNA
REMOVAL
1. Remove splash cover on RH undercover.
2. Remove drive belt.
●Keep auto-tensioner pulley fixed with a tool such as a short-length screwdriver.
3. Remove drive belt auto-tensioner.
●Remove and install drive belt auto-tensioner by fixing auto-tensioner pulley.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
Install drive belt auto-tensioner carefully not to damage the water pump pulley.

CYLINDER BLOCK
CAUTION:
Identify installation positions, and store them without mixing them up.
ASSEMBLY
1. Fully air-blow the engine coolant and engine oil passages in the cylinder block, the cylinder bore and the
crankcase to remove any foreign material.
CAUTION:
Use a goggles to protect your eye.
2. Install each plug to the cylinder block.
●Apply liquid gasket.
Use Genuine Liquid Gasket or equivalent.
●Replace the copper washers with new ones.
3. Install the main bearings and the thrust bearings.
a. Remove dust, dirt, and engine oil on the bearing mating sur-
faces of the cylinder block and the lower cylinder block.
b. Install the thrust bearings to the both sides of the No. 3 journal
housing on the cylinder block.
●Install the thrust bearings with the oil groove facing the crank-
shaft arm (outside).
c. Install the main bearings paying attention to the direction.
●The main bearing with an oil hole and groove goes on the cyl-
inder block. The one without them goes on the lower cylinder
block.
●Only the main bearing (on the cylinder block) for No. 3 journal
has different specifications.
●Before installing the bearings, apply engine oil to the bearing
surface (inside). Do not apply engine oil to the back surface,
but thoroughly clean it.
●When installing, align the bearing stopper to the notch.
●Ensure the oil holes on cylinder block and those on the corre-
sponding bearing are aligned.
4. Install the signal plate to the crankshaft.
a. Position crankshaft and signal plate using a positioning dowel
pin, and tighten mounting bolts.
b. Remove dowel pin.
CAUTION:
Be sure to remove dowel pin.
NOTE:
Dowel pins of crankshaft and signal plate are provided as a set
for each.
If dowel pin is not available (when reusing crankshaft and sig-
nal), use M6-bolt (length below the head of the bolt should be 10
mm or more) as a substitute.
