Why This Parts Book Belongs in Your Workshop

When you are rebuilding a D85ESS-2 steering clutch, chasing a hydraulic leak through the PPC piping, or simply replacing a worn track roller, guessing part numbers wastes time and money. This Komatsu D85ESS-2 parts catalog gives you the exact original part number for every component on the machine, indexed by assembly and tied to the correct serial-number range so you order the version that actually fits your dozer. It is the same reference used at the parts counter – now on your screen.

Because the book is organized by system, you can also use it as a teardown and reassembly guide: exploded illustrations show how components stack together, and the quantity columns tell you exactly how many bolts, washers, O-rings and shims are needed. Whether you maintain one machine or run a fleet, having the correct part numbers on hand shortens every repair and prevents the costly mistake of installing the wrong component.
