DESCRIPTION:
KOMATSU WA430-6E0 WHEEL LOADER SHOP MANUAL VEBM948102 – PDF DOWNLOAD
Composition of shop manual
This shop manual contains the necessary technical information for services performed in a workshop. For ease of understanding, the manual is divided into the following sections.
00.Index and foreword
This section explains the shop manuals list, table of contents, safety, and basic information.
01.Specification
This section explains the specifications of the machine.
10.Structure, function and maintenance standard
This section explains the structure, function, and maintenance standard values of each component. The structure and function sub-section explains the structure and function of each component. It serves not only to give an understanding of the structure, but also serves as reference material for troubleshooting. The maintenance standard sub-section explains the criteria and remedies for disassembly and service.
20.Standard value table
This section explains the standard values for new machine and judgement criteria for testing, adjusting, and troubleshooting. This standard value table is used to check the standard values in testing and adjusting and to judge parts in troubleshooting.
30.Testing and adjusting
This section explains measuring instruments and measuring methods for testing and adjusting, and method of adjusting each part. The standard values and judgement criteria for testing and adjusting are explained in Testing and adjusting.
40.Troubleshooting
This section explains how to find out failed parts and how to repair them. The troubleshooting is divided by failure modes. The “S mode” of the troubleshooting related to the engine may be also explained in the Chassis volume and Engine volume. In this case, see the Chassis volume.
50.Disassembly and assembly
This section explains the special tools and procedures for removing, installing, disassembling, and assembling each component, as well as precautions for them. In addition, tightening torque and quantity and weight of coating material, oil, grease, and coolant necessary for the work are also explained.
90.Diagrams and drawings (chassis volume)/Repair and replacement of parts (engine volume)
A. Chassis volume
This section gives hydraulic circuit diagrams and electrical circuit diagrams.
B. Engine volume
This section explains the method of reproducing, repairing, and replacing parts.
