Komatsu GD825A-2 Motor Grader Parts Book FEN01742-03 – Serial 12643 and Up

Description

Komatsu GD825A-2 Parts Book – FEN01742-03

This is the complete Komatsu GD825A-2 parts catalog, published under document number FEN01742-03. It covers the GD825A-2 motor grader from machine serial number 12643 and up, fitted with the S6D140E-2B-6 engine from engine serial number 39616 and up. Every entry in the book carries its part number, part name, quantity required per machine, and the serial number range over which that part applies, all cross-referenced to illustrated exploded views of the assemblies.

Because this is a serial-number-specific parts book rather than a generic catalog, the parts listed here match the build configuration of the covered machines. That detail matters whenever a machine has been through running production changes – ordering from the wrong catalog is one of the most common reasons a replacement arrives and does not fit the machine in front of you.

Put together, this is a complete factory-style parts reference for the GD825A-2 – useful both as a lookup tool when ordering and as a reference for understanding how the machine is assembled. The exploded diagrams show how each component breaks down, the parts lists identify the individual pieces, and the serial number columns tell you whether a particular part applies to a given machine.

What This Parts Book Lets You Do

With the Komatsu GD825A-2 parts book on hand you can identify a component from the diagram instead of guessing at a description, quote the exact part number to a dealer or supplier, check that the part is correct for your specific machine serial number before ordering, and see how a sub-assembly is put together when a part has to be replaced.

It also helps with the practical side of parts work: confirming quantities per machine so you order the right number of bolts, seals, and gaskets; spotting superseded part references shown with the catalog’s own interchange symbols; and locating options and attachments such as water separators, rippers, accumulators, and cold-weather specification parts that appear in the same book as the standard items.

Why It Matters

A wrong part number costs time. It means a return, a re-order, and downtime on a machine that is usually needed back on site. This book removes the guesswork by tying every part number to a specific serial number range, so what you look up matches what is on the machine. For anyone maintaining a GD825A-2, that accuracy is what separates a fast fix from a long wait.
