What This Parts Catalog Provides

This is not a service manual or a repair guide. It is a comprehensive parts identification and ordering reference. Every illustration is an exploded view that shows how components fit together, and every item number on those illustrations corresponds to a line in the parts table with the Komatsu part number, description, quantity required, and serial number applicability.

Because this catalog covers serial number 60001 and up, you can confidently identify the correct part for your specific machine. Where a part changed during production, the catalog shows both options with the serial number break point clearly marked. This is critical for avoiding ordering mistakes, especially on wear items, seals, gaskets, and components that were revised mid-production.

The engine section alone covers the complete SAA6D114E-3D-WT diesel engine, including cylinder head, cylinder block, front gear train, flywheel housing, crankshaft, camshaft, pistons, turbocharger, air intake, cooling, fuel, lubrication, and electrical systems. Each system is broken down to the individual bolt, O-ring, and gasket.

The hydraulic section covers the main pump, main valve in every configuration (standard, 1-actuator, 2-actuator with quick coupler, 2-actuator), all lines and piping, solenoid valves, pressure switches, and accumulators. The undercarriage section covers the complete track frame, idlers, track rollers, carrier rollers, track shoes, and final drives. The work equipment section covers booms, arms, buckets, cylinders, and all attachment lines.

The operator’s compartment section is particularly detailed, covering every cab configuration and interior component, from the seat and seat belt to the air conditioner, monitor, wiring harness, floor components, and all control levers and valves.

Why This Parts Catalog Matters

Ordering the wrong part is expensive and frustrating. It costs you time, return shipping, and downtime. This catalog eliminates that risk by giving you the exact part number for your machine’s serial number. The exploded diagrams also help you understand how assemblies come apart and go back together, which is invaluable when you are working on a complex system like the main valve or the swing machinery.

Whether you are a Komatsu dealer parts counter, an independent repair shop, a fleet maintenance manager, or an owner-operator who does their own repairs, having the complete parts catalog for your machine means you can identify any component on the excavator and order it with confidence.
