GENERAL REPAIR INSTRUCTIONS
1. For assurance of safety, park the vehicle on level ground and brace the front or rear wheels when lifting the vehicle.
2. Raise the vehicle with a jack set against the axle or frame and perform service operation after supporting the vehicle
on chassis stands.
3. Before performing service operation, disconnect grounding cable from the battery to reduce the chance of cable
damage and burning due to short-circuiting.
4. Use a cover on body, seats and floor to protect them against damage and contamination.
5. Brake fluid and anti-freeze solution must be handled with reasonable care as they can cause paint damage'
6. The use of proper tools and special tools where specified, is important to efficient and reliable service operation.
7. Use genuine lsuzu parts.
8. Used cotter pins, gaskets, O-rings, oil seals, lock washers and self lock nuts should be discarded and new ones
should be prepared for installation as normal function of the parts can not be maintained if these parts are reused.
9. To facilitate proper and smooth reassembly operation. keep disassembled parts neatly in groups.
Keeping fixing bolts and nuts separate is very important as they vary in hardness and design depending on position
of installation.

1 -2 GENERAL INFORMATION
10. Clean the parts before inspection or reassembly. Also clean oil ports, etc. using compressed air to make certain
they are free from restrictions.
1 1. Lubricate rotating and sliding faces of the parts with oil or grease before installation.
12. When necessary, use a sealer on gaskets to prevent leakage.
13. Carefully observe all specifications for bolt and nut torques.
14, When service operation is completed, make a final check to be sure service has been done properly.
15. For assurance of safety, always release air pressure solely from the air tanks before disconnecting pipes, hoses or
other parts from any unit under air pressure.
HOW TO USE THIS MANUAL
Find the Wpe of unit or equipment to be serviced by referring to the "Application chart" or "ldentification of unit or
equipment" included in this section.
Find the applicable section by refering to the index.
This manual includes "General information" section in which service data, maintenance items and specifications
with torques are included.
Each section includes removal and installation, disassembly, inspection and repair and reassembly. When the
same service operation applies to more than one un;ts or equipments. notice is inserted stating, "Refer to manual for
other units or equipments".
ln removal and installation section. description of self-explanatory items such as removal of individual parts from
unit to be removed, is omitted and important operation such as adjustments, torque specifications, etc. are dealt
with mainly.
6. The service standard is indicated in terms of "Standard" and "Limit".
The "standard" means the assembly standard and standard range within which the parts are considered serviceable.
"Limit" indicates the limit value (Correction or replacement is necessary when measurement is beyond this limit.)
7. ln this manual, the components and parts are printed in singular form.
