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.
The first section covers component descriptions,
truck specifications and safe work practices, as well
as other general information. The major portion of the
manual pertains to disassembly, service and
reassembly. Each major serviceable area is dealt
with individually. For example, the disassembly,
service and reassembly of the radiator group is
discussed as a unit. The same is true of the engine
and engine accessories, and so on through the entire
mechanical detail of the truck. Disassembly should
be carried only as far as necessary to accomplish
needed repairs.
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.
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 specific torque values, standard torque
values should be used. Standard torque values are
shown in torque charts later in this section. Specific
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.
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. 960E).
The three numbers represent the basic truck
model.
The letter “E” designates an Electrical wheel
motor drive system.
The Product Identification Number (vehicle serial
number) contains information which identifies several
characteristics of this unit. For a more detailed
explanation, refer to the Operation and Maintenance
Manual.
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 fuel &
lubr 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.
