What’s inside

The Komatsu 730E Parts Book compiles a comprehensive catalog of components organized by major assemblies. Expect exploded-view illustrations that clearly show how each part fits within the system, from the engine bay through the drive train, hydraulic circuits, braking systems, and electrical harnesses. Each illustration is paired with OEM part numbers, compatible sub-assemblies, and notes that help technicians confirm fitment across related components. The content is indexed for quick navigation, making it easier to locate service parts, wear items, and replacement fasteners without paging through irrelevant pages.

Key areas covered

While the exact layout may vary by edition, you can typically rely on detailed references for:

• Engine, fuel system, and cooling components
• Transmission, differentials, and driveline assemblies
• Axles, steering, and suspension hardware
• Hydraulic pumps, valves, cylinders, and plumbing
• Brake systems, air and hydraulic lines
• Electrical harnesses, controllers, and sensor placement
• Structural brackets, fasteners, and wear-items organized by subsystem

Benefits

• Faster parts identification: Exploded views and grouped assemblies reduce the time needed to locate the correct part number and description.
