NON-OEM PARTS IN CRITICAL SYSTEMS
For safety reasons, Komatsu America Corp. strongly recommends against the use
of non-OEM replacement parts in critical systems of all Komatsu equipment. Critical
systems include but are not limited to steering, braking and operator safety sys-
tems.
Replacement parts manufactured and supplied by unauthorized sources may not be
designed, manufactured or assembled to Komatsu's design specifications; accord-
ingly, use of such parts may compromise the safe operation of Komatsu products
and place the operator and others in danger should the part fail.
Komatsu is also aware of repair companies that will rework or modify an OEM part
for reuse in critical systems. Komatsu does not generally authorize such repairs or
modifications for the same reasons as noted above.
Use of non-OEM parts places full responsibility for the safe performance of the
Komatsu product on the supplier and user. Komatsu will not in any case accept
responsibility for the failure or performance of non-OEM parts in its products,
including any damages or personal injury resulting from such use.

OM1085 01/16 Introduction - Section 10
Page 10-1
FOREWORD
This manual is written for use by the operator and/or the service technician and is designed to help these persons
to become fully knowledgeable of the truck and all its systems in order to keep it operating safely and efficiently.
All operators and maintenance personnel must understand the content in this manual before operating, maintain-
ing or performing operational checks on the truck. All safety notices, warnings and cautions must be understood
before operating or repairing the truck.
The first section is an introduction to the manual and contains a table of contents to locate specific areas of inter-
est. Other sections include Safety, Operation, Maintenance, Specifications, and Optional Equipment.
This manual shows dimensioning of metric and (U.S. standard) units throughout. All references to right, left, front,
or rear are made with respect to the operator's normal seated position, unless specifically stated otherwise.
Standard torque requirements are shown in torque charts in the Introduction section and individual torques are pro-
vided in the text in bold face type, such as 135 N·m (100 ft lb). All torque specifications have ±10% tolerance
unless otherwise specified.
The illustrations used in this manual are typical of the component shown and may not be an exact reproduction of
what is found on the truck.
A product identification plate is located on the frame in front of the right side front wheel and designates the truck
model number, product identification number (vehicle serial number), and maximum Gross Vehicle Weight (GVW)
rating.
The product identification number (vehicle serial number) contains information which will identify the original manu-
facturing bill of material for this unit. This complete number will be necessary for proper ordering of many service
parts and/or warranty consideration.
The GVW is what determines the load on the drive train, frame, tires, and other components. The vehicle design
and application guidelines are sensitive to the total maximum GVW. GVW is the total truck weight. This is equal to
the empty vehicle weight + the fuel & lubricants + the payload.
To determine allowable payload: Service all lubricants to the proper level including the fuel tank. Weigh the empty
truck This includes all accessories, body liners, tailgates, etc. Record this value and subtract from the GVW rating.
The result is the allowable payload.
NOTE: Accumulations of mud, frozen material, etc. become a part of the GVW and reduces allowable payload. To
maximize payload and to keep from exceeding the GVW rating, these accumulations must be removed as often as
practical.
Exceeding the allowable payload will reduce expected life of truck components.

This manual shows dimensioning of U.S. standard and metric (SI) units throughout. All references to right, left,
front, or rear are made with respect to the operator's normal seated position, unless specifically stated otherwise.
When assembly instructions are provided without references to torque values, standard torque values are to be
assumed. Standard torque requirements are shown in torque charts on the following pages of this section, and in
the General Information section of the truck service manual. Individual torques when provided in the text are in bold
face type, such as 135 N·m (100 ft lb). All torque specifications have ±10% tolerance unless otherwise specified.

TORQUE TABLES AND CONVERSION CHARTS
This manual provides dual dimensioning for many
specifications. Metric units are specified first, with
U.S. standard units in parentheses. When torque val-
ues are not specified in the assembly instructions
contained in this manual, use the standard torque
value for the hardware being used. Standard value
torque tables are contained in this chapter for metric
and SAE hardware.
NOTE: This truck is assembled with both metric and
SAE (U.S.) hardware. Reference the correct table
when determining the proper torque value.
References throughout the manual to standard
torques or other standard values will be to one of
the following tables. Do not use standard values
to replace specific torque values in assembly
instructions.
For values not shown in any of the charts or tables,
standard conversion factors for most commonly used
measurements are provided in the following tables.

EFFECT OF SPECIAL LUBRICANTS
On Fasteners and Standard Torque Values
The Komatsu engineering department does not
recommend the use of special friction-reducing
lubricants, such as Copper Coat, Never-Seez®, and
other similar products, on the threads of standard
fasteners where standard torque values are applied.
The use of special friction-reducing lubricants will
significantly alter the clamping force being applied to
fasteners during the tightening process.
If special friction-reducing lubricants are used with
the standard torque values listed in this chapter,
excessive stress and possible breakage of the
fasteners may result.
Where the torque tables specify “Lubricated
Threads” for the standard torque values listed, these
standard torque values are to be used with simple
lithium base chassis grease (multi-purpose EP NLGI)
or a rust-preventive grease (see below) on the
threads and seats unless specified otherwise.
Ensure the threads of fasteners and tapped holes are
free of burrs and other imperfections before
assembling.
Suggested* Sources for Rust Preventive Grease:
• American Anti-Rust Grease #3-X from Standard
Oil Company (also American Oil Co.)
• Gulf NoRust #3 from Gulf Oil Company.
• Mobilarma 355, Product No. 66705 from Mobil
Oil Corporation.
• Rust Ban 326 from Humble Oil Company.
• Rustolene B Grease from Sinclair Oil Co.
• Rust Preventive Grease - Code 312 from the
Southwest Grease and Oil Company.
This list represents the current engineering approved
sources for use in Komatsu manufacture. It is not
exclusive. Other products may meet the same
specifications of this list.
STANDARD TIGHTENING TORQUES
For Class 10.9 Cap screws & Class 10 Nuts
The following specifications apply to required
assembly torques for all metric class 10.9 finished
hexagon head cap screws and class 10 nuts.
• Cap screw threads and seats shall not be
lubricated when assembled. These specifications
are based on all cap screws, nuts, and hardened
washers being phosphate and oil coated.
If zinc-plated hardware is used, each piece must
be lubricated with simple lithium base chassis
grease (multi-purpose EP NLGI) or a rust

STANDARD TIGHTENING TORQUES
For SAE Grade 5 and Grade 8 Cap screws
The following specifications apply to required assem-
bly torques for all grade 5 and grade 8 cap screws.
• Cap screw threads and seats shall be lubricated
when assembled.
Unless instructions specifically recommend
otherwise, these standard torque values are to be
used with simple lithium base chassis grease
(multi-purpose EP NLGI) or a rust- preventive
grease (see list, previous page) on the threads.
• Torques are calculated to give a clamping force
of approximately 75% of proof load.
• The maximum torque tolerance shall be ±10% of
the torque value shown.
• In the following table under Cap Screw Size, the
first number represents the shank diameter (in.).
The second number represents threads per inch.
Example: 7/16 - 20
7/16 = shank diameter (7/16 inch (0.438 inch))
20 = threads per inch
