Working through this Komatsu GD755-5R parts book FEN04876-01 gives a technician, parts counter, or fleet owner a full map of the machine. Each illustration is exploded so every bracket, bolt, seal, bushing, harness, hose, cylinder, pump, valve, and plate appears at its exact position in the assembly. The parts lists that follow quote the Komatsu part number, name, quantity used per machine or per assembly, and the serial number range the part applies to. Where a part number has been superseded, the interchangeability codes in the code column tell you the substitute that Komatsu now supplies. Where a part is only sold as an assembly, service kit, or semi-finished item, the code column flags that as well so you know what will actually arrive.

How the Komatsu GD755-5R FEN04876-01 Parts Catalog Is Organised

The book opens with the parts book foreword, explanation of codes, and the illustration and parts list conventions. It then moves into an illustrated table of contents grouped by machine system, so the entire hydraulic section, the entire power train section, the entire cooling system, and the whole work equipment group are contiguous. Each figure is numbered (FIG. A1110-001001, for example, covers the Rocker Arm Housing Cover) and every figure is followed immediately by its matching parts list. The 634-page document ends with the field repair service kits and a numerical index that lets you jump straight from a part number to the page and index number that uses it.

Because the catalog separates the chassis volume (machine serial 10250 and up) from the engine volume (SAA6D125E-5HR engine serial 663013 and up), the applicable serial number columns in each parts list make it easy to confirm a part fits the specific unit sitting in front of you, even when a running change happened mid-production.

What This Komatsu GD755-5R Motor Grader Parts Catalog Lets You Do

With the Komatsu GD755-5R parts book FEN04876-01 on hand you can identify the correct replacement part for any major system on the grader without guesswork. That means the right hydraulic cylinder seal kit, the right blade lift check valve, the right ECMV assembly inside the clutch control valve, the right tandem brake caliper component, the right SAA6D125E-5HR fuel injector, or the right ROPS cab door latch, all traced from the exploded view to the exact part number and quantity in a single pass.

Getting the correct Komatsu part number is the difference between a machine that goes back to work the same day and a machine that sits idle while the wrong component is returned and re-ordered. The serial number range columns, the interchangeability codes, and the assembly-only flags in this parts catalog exist precisely to prevent that kind of downtime. It also means accurate parts quotes, reliable inventory planning, and a clear picture of what components belong to which subassembly before anything is dismantled.
