Description

Komatsu GD655-3C Parts Book KEPB074501

This is the complete illustrated parts book for the Komatsu GD655-3C motor grader, covering the 6D665-3C differential lock type from serial number B15001 and up. The engine referenced throughout is the SAA6D114E-2BB-VH starting at engine number 2B80003 and up. Every assembly is broken down into its component parts with index numbers, part numbers, descriptions, quantities and serial-number applicability, so you can identify exactly which part belongs to your machine before ordering or cross-referencing.

Each section is laid out so the illustration page sits on the left with numbered index callouts, and the corresponding list page on the right carries the part number, description, quantity and serial-number applicability. The symbols used on the list pages — interchangeable parts, discontinued parts, parts supplied as assemblies, kit parts and components — are explained in the foreword, so you can read the tables with confidence. Because the entire machine is documented assembly-by-assembly rather than as a general overview, you can work through the drivetrain, hydraulic system, work equipment, operator’s cab and electrical system down to the nut-and-bolt level.

What This Komatsu GD655-3C Parts Book Gives You

For anyone maintaining, repairing or restoring a GD655-3C grader, the practical value is in the part numbers themselves. Instead of guessing a description or calling a dealer with a vague idea of the component, you can locate the exact illustration, read off the index number and find the corresponding part number and quantity in the adjacent list. The serial-number columns tell you whether the part applies to your specific machine — important on a production series that was updated across B15001-up — and the symbol codes flag items that have been superseded, replaced, or are only available as part of an assembly.

The engine section alone covers the SAA6D114E-2BB-VH from cylinder head and turbocharger through to fuel injection pump, injection nozzles, starting motor, alternator and gasket kits, with exploded views showing how each sub-assembly fits together. The transmission and rear axle sections break down the torque converter, clutch packs, final drives, tandem cases, brake calipers and differential lock components. The hydraulic section documents the main control valve, hydraulic pump, priority valve, steering valve, pilot check valves, swivel joint and every hose and tube run across the machine. The operator’s compartment section covers the cab structure, doors, wipers, air conditioning, heater piping, control levers, pedals and electrical console in similar detail.

Why It Matters

Ordering the wrong part on heavy equipment is expensive and slow. A correct parts book removes the guesswork: you confirm the part number, the quantity required and the serial applicability before the order goes out. It also makes cross-referencing possible when a part has been superseded — the symbol codes point you to the current replacement. For anyone rebuilding a component, the exploded illustrations show assembly order and relationships that a parts description alone cannot convey.
