Proposition 65 Warning
Mercury and mercury compounds are known to the State of California to cause developmental prob-
lems. This machine may be equipped with optional HID lamps which contain mercury. There is no risk
of exposure unless the lamps are broken. However, the lamps must be reused, recycled or properly
disposed of in accordance with Local, State and Federal Laws at the end of their useful lives.

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 Kom-
atsu product on the supplier and user. Komatsu will not in any case accept responsi-
bility for the failure or performance of non-OEM parts in its products, including any
damages or personal injury resulting from such use.

INTRODUCTION
FOREWORD
This manual is written for use by the operator and/or the service technician. It is designed to help these persons to
become fully knowledgeable of the truck and all of its systems in order to keep it operating safely and efficiently. All
operators and maintenance personnel should read and understand the information in this manual before operating
the truck or performing maintenance and/or operational checks on the truck. All safety notices, warnings, and
cautions should be understood and followed when operating the truck or performing repairs on the truck.
A product identification plate is located on the frame in front of the right side front wheel. It designates the Truck
Model Number, Product Identification Number (vehicle serial number), and Maximum GVW (Gross Vehicle Weight)
rating.
The KOMATSU truck model designation consists of three numbers and one letter (i.e. 860E).
The three numbers represent the basic truck model.
The letter “M”, when present, designates a Mechanical drive system.
The letter “E”, when present, designates an Electrical wheel motor drive system.
The Product Identification Number (vehicle serial number) contains information which identifies the original
manufacturing bill of material for this unit. This complete number will be necessary for proper ordering of many
service parts and/or warranty consideration.
The Gross Vehicle Weight (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 maximum GVW.
GVW is total weight: empty vehicle weight + fuel & lubricants + payload.
To determine the allowable payload, fill all lubricants to the proper level and fill the fuel tank of an empty truck
(which includes all accessories, body liners, tailgates, etc.), and then weigh the truck. Record this value and
subtract it from the GVW. The result is the allowable payload.
NOTE: Accumulations of mud, frozen material, etc, become part of the GVW and reduces the allowable payload.
To maximize payload and to keep from exceeding the maximum GVW rating, these accumulations should be
removed as often as practical.
Exceeding the allowable payload will reduce the expected life of truck components.

OM1200 02/11 Torque Tables And Conversion Charts - Section 12
Page 12-1
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.
NOTE: Ensure the threads of fasteners and tapped
holes are free of burrs and other imperfections before
assembling.

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
preventive grease (see list, this page) to achieve
the same clamping forces provided below.
• Torques are calculated to give a clamping force
of approximately 75% of proof load.
• The maximum torque tolerance shall be within
±10% of the torque value shown.
• In the following table under “Cap Screw Size”, the
first number represents the shank diameter
(mm). The second number represents threads
per millimeter.
Example: M20 x 2.25
M20 = shank diameter (20 mm)
2.25 = thread pitch in millimeters

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
