What’s inside and how it helps

The HM350-2 Parts Book is organized to mirror how technicians think about a machine, moving from broad system overviews to precise part details. You’ll find:

• System-by-system diagrams for the engine, hydraulic circuits, cooling and lubrication, fuel system, transmission, electrical harnesses, and control panels.
• Exploded views that show how assemblies break down into sub-assemblies and individual components, making disassembly and reassembly processes clearer and less error-prone.
• Part numbers and descriptions linked to each diagram, enabling quick ordering and accurate stock checks.
• Serial-number cross-references to confirm you’re looking at components that fit HM350-2 units in the ecot3/JPN specification, reducing misfits and returns.
• Torque values, fastener types, and installation notes where applicable, helping to avoid over- or under-tightening and related issues during repairs.
• Interchange and compatibility notes that clarify when a part number applies across related HM350-2 configurations, streamlining sourcing across your fleet.

Who benefits most

• Independent repair shops servicing Komatsu HM350-2 excavators in Japan or with Japanese-spec configurations.
• Fleet managers and maintenance schedulers who need a reliable reference to plan part renewals and preventive maintenance.
• Field technicians who require dependable, portable documentation for on-site troubleshooting and quick repairs.
