Komatsu 140E-7 Series Engine Shop Manual SEN06498-16 – PDF DOWNLOAD 

Foreword, Safety, Basic Information
How to Read the Engine Shop Manual
• Some of the attachments and options described in this shop manual may not be available in some areas. If
they are required, consult your Komatsu distributor.
• The materials and specifications are subject to change without notice.
• Shop manuals are available for “machine part” and “engine part”. For the engine unit, see the shop manual
for the machine which has the same engine model.
• Actual machine may differ from the images which are contained in this manual. A typical model is shown in
the illustrations of this shop manual.
Composition of the Shop Manual
This shop manual contains technical information necessary to perform services in workshops. It is divided into
the following chapters for the ease of use.
00 Index and Foreword
This section describes the index, foreword, safety, and basic information.
01 SpecificationS
This section describes the specifications of the machine.
10 Structure and Function
This section describes the structure and operation of each component with respect to each system. “Structure
and Function” is helpful in not only understanding the structure of each component but performing troubleshooting.
20 Standard Value Table
This section describes the standard values for new machine and failure criteria for testing and adjusting, and
troubleshooting. Use the standard values table to check the standard values for testing and adjusting, and judge
troubles in troubleshooting.
50 Disassembly and Assembly
This section describes the special tools, work procedures, and safety precautions necessary for removal, installation,
disassembly, and assembly of the components and parts. In addition, tightening torques, quantity, and
weight of the coating materials, lubricants, and coolant necessary to these works are shown.
60 Maintenance Standard
This section describes the maintenance standard value of each component. The maintenance standard shows
the criteria and remedies for disassembly and assembly.
