5. Apply a bead of sealant (TB-1207C or equivalent) in the
grooves of both bearing shells.

Important!
After installation of bearing cover, press in sealing compound
again from above, until compound emerges at the joints.


Torque - Angle Method

m) +45
to
60
.
Use new bolts.

6. Install oil pump, oil pan, bearing bridge rear crankshaft
sealing, flywheel/drive plate, and aggregates according to
the corresponding operations.









Inspection
Bearing play - bearing cover removed

Measure
With "Plastigage" (ductile plastic threads)
Cut threads to length of bearing width and lay axiaity between
crankshaft journal and bearing shell (arrowed).
Install bearing cover with correct torque.

Important!
Grease crankshaft journal and lubricate bearing shell slightly
so that the thread does not tear when the bearing cover is
moved.


Crankshaft
Inspection
End play when bearing shells are installed.
Front end contact surfaces of flywheel/flexible plate.
Permissible end play - see "Technical Data "

6C-14 ENGINE FUEL (C24SE)
Removal
CAUTION: When repair to the fuel system has been
completed, start engine and check the fuel system
for loose connection or leakage. For the fuel system
diagnosis, see Section “Driveability and Emission".
1. Disconnect battery ground cable.
2. Loosen slowly the fuel filler cap.
NOTE: To prevent spouting out fuel to change the
pressure in the fuel tank.
NOTE: Cover opening of the filler neck to prevent any
dust entering.
3. Jack up the vehicle.
4. Support underneath of the fuel tank with a lifter.
5. Remove the inner liner of the wheel house on rea
r
left side.
6. Remove fasten bolt to the filler neck from the
body.
7. Disconnect the quick connector (8) into the fuel
tube from the fuel pipe and the evapo tube from
evapo joint connector.
NOTE: Cover the quick connector to prevent any dus
t
entering and fuel leaking.
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in
this section when performing any repairs.
8. Remove fasten bolt (1) to the tank band and the
tank band (2).
9. Disconnect the pump and sender connector on the
fuel pump and remove the harness from weld clip
on the fuel tank.
10. Lower the fuel tank (6).
NOTE: When the fuel tank is lowered from the vehicle,
don’t scratch each hose and tube by around other pars.


Installation
1. Rise the fuel tank into position.
NOTE: Ensure hoses and tubes do not foul on othe
r
component.
2. Connect the pump and sender connector to the
fuel pump and install harness to into the plastic clip
welded to the top of the fuel tank..
NOTE: The connector must be certainly connected
against stopper.
Ensure tank band anchor mates with guide hole on
frame.
3. Install the tank band to fasten bolt.
Torque: 68 N




m (6.9kg




m/50 lb ft)
NOTE: The anchor of the tank band must be certainly
installed to guide hole on frame.
4. Connect the quick connector from the fuel tube to
the fuel pipe and the evapo tube from evapo join
t
connector.
NOTE: Pull off the left checker into the fuel pipe.
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in
this section when performing any repairs.
5. Install the filler neck to the body by bolt.
6. Install the inner liner of the wheel house on rea
r
side.
7. Remove lifter to support underneath of the fuel
tank.
8. Put back the vehicle.
9. Tigten the filler cap until at least three clicks are
heard.
10. Connect the battery ground cable.

0A-2 GENERAL INFORMATION
GENERAL REPAIR INSTRUCTIONS
1. Park the vehicle on level ground and chock the front or rear wheels before lifting the vehicle.
2. Raise the vehicle with a jack set against the axle or the frame.
3. Support the vehicle on chassis stands.
4. Use covers on the vehicle body, seats, and floor to prevent damage and/or contamination.
5. Disconnect the grounding cable from the battery before performing service operations.

This will prevent cable damage or burning due to short circuiting.
6. Handle brake fluid and antifreeze solution with great care.

Spilling these liquids on painted surfaces will damage the paint.
7. The use of the proper tool(s) and special tool(s) where specified is essential to efficient, reliable, and safe
service operations.
8. Always use genuine ISUZU replacement parts.
9. Discard used cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts at disassembly.
Normal function of these parts cannot be guaranteed if they are reused.
10. Prepare new cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts for installation.
11. Keep the disassembled parts neatly in groups.
This will facilitate smooth and correct reassembly.
12. Keep fixing nuts and bolts separate.
Fixing nuts and bolts vary in hardness and design according to installation position.
13. Clean all parts before inspection or reassembly.
14. Clean the oil ports and other openings with compressed air to make certain that they are free from dirt and
obstructions.
15. Lubricate the rotating and sliding faces of all moving parts with oil or grease before installation.
16. Use the recommended liquid gasket to prevent leakage.
17. Carefully observe all nut and bolt torque specifications.
18. When removing or replacing parts that require refrigerant to the discharged from the Air conditioning system, be
sure to use the Vehicle Refrigerant Recovery and Recycling Equipment (VRRRE) to recover and recycle R134a,
to promote the movement for the protection of the ozone layer covering the earth.
19. Check and recheck your work. No service operation is complete until you have done this.
