The Komatsu GD675-3 (JPN) S/N 51301-UP Parts Book is the official reference for service teams, fleet operators, and parts departments maintaining this robust excavator. It’s designed to help you identify the exact components you need, quickly and accurately, so downtime is minimized and maintenance stays on track.

This digital downloadable PDF manual is tailored for units built for the Japanese market, covering serial numbers from 51301 upward. Inside, you’ll find exploded-view diagrams, system-by-system part lists, OEM part numbers, and cross-references that map each component to its assembly and function. The manual is organized by major subsystems—engine and powertrain, hydraulic circuitry, undercarriage and track components, electrical harnesses, and linkage—so technicians can locate the right part without hunting through unrelated pages. The file is designed for practical use on the workshop floor: high-contrast images, readable callouts, and a clean layout that supports quick scanning during disassembly, ordering, and reassembly. Because it’s a digital downloadable PDF manual, you can store it on your laptop, tablet, or phone, annotate pages with notes, and print the sections you need for a job—whether you’re in a shop or at a remote site.
