KOMATSU WA380-3MC WHEEL LOADER SERVICE REPAIR MANUAL (SN:A51001 and up) KOMATSU WA380-3MC

• This shop manual has been prepared as an aid to improve the quality of repairs by giving the serviceman an accurate understanding of the product and by showing him the correct way to perform repairs and make judgements. Make sure you understand the contents of this manual and use it to full effect at every opportunity.
• This shop manual mainly contains the necessary technical information for operations performed in a service workshop. For ease of understanding, the manual is divided into the following sectio ns. These sections are further divided into each main group of components.
• GENERAL
  This section lists the general machine dimensions, performance specifications, component weights, and fuel, coolant and lubricant specification charts.
• STRUCTURE AND FUNCTION
  This 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.
• TESTING AND ADJUSTING
  This section explains checks to be made before and after performing repairs, as well as adjustments to be made at completion of the checks and repairs. Troubleshooting charts correlating “Problems” to “Causes” are also included in this section.
• DISASSEMBLY AND ASSEMBLY
  This section explains the order to be followed when removing, installing, disassembling or assembling each component, as well as precautions to be taken for these operations.
• MAINTENANCE STANDARD
  This section gives the judgement standards when inspecting disassembled parts.
