Komatsu GD705A-4 Motor Grader Parts Book – Serial 23063 and Up PDF

Description

Komatsu GD705A-4 Motor Grader Parts Book – Serial Numbers 23063 and Up

Document PEPB057403 is the complete illustrated parts book for the Komatsu GD705A-4 Motor Grader, covering machines from serial number 23063 and up. Each assembly on the machine is broken down into a numbered exploded illustration on the left-hand page and a matching parts list on the right-hand page, giving the part number, part name, quantity used per machine, and the serial number range that part applies to. For anyone maintaining, rebuilding or simply ordering parts for a GD705A-4, this is the reference that turns a vague description of a broken component into an exact, orderable line item.

Taken as a whole, this Komatsu GD705A-4 Motor Grader Parts Book gives an owner or workshop a complete, illustrated map of the machine, from the cylinder head down to the blade edge. Every figure is keyed by index number to a list that states exactly which part number, part name, quantity and serial-number range apply, so you can trace a component through its parent assembly, confirm a substitution, and order without guesswork. Because the GD705A-4 was built in several configurations, including the cold-terrain packages and the D.D.V. setup, the book lists the alternative part numbers side by side where the machine changed. That is the difference between ordering a part that fits and one that almost fits.

How the Parts Lists Are Read

Each illustration page carries an index number against every visible component. The facing list then repeats those index numbers in order and gives the part number in the PART No. column, the part name in the DESCRIPTION column, the quantity in the QTY column, and the applicable machine serial number in the SERIAL No. column. Where a part name is marked with a dot it is part of the assembly named on the line above; where it is marked with two dots it belongs to a sub-assembly inside that assembly. This is what lets you jump from a single bolt, seal or bracket straight to the parent group it belongs to, and vice versa.

Symbols, Substitutions and Kits

The book uses a coded symbol system alongside the part numbers. These markers flag interchangeable parts, parts that can be used in place of the part listed immediately above, discontinued parts with the replacement shown on the line above, parts supplied only as a complete set, parts supplied only as an assembly, kit parts, semi-finished parts requiring further work, parts shipped with an undercoat, and parts shipped in a colour different from the machine’s original. Cold-weather parts for the A specification (-30 degrees C) and B specification (-50 degrees C) machines are also marked with their own codes. Reading these markers correctly is what stops you ordering a superseded or kit-only part on its own.

Serial Number Coverage and Spec Variants

This edition applies to GD705A-4 machines from serial 23063 and up. Many groups are printed twice within the same figure set, once for the standard machine and once for the cold-terrain specification, and the hydraulic sections split again for the D.D.V. specification. The serial number column in each list tells you at a glance whether a part applies to your machine. If your GD705A-4 falls inside the 23063-and-up range, this book covers it.

What This Parts Book Lets You Do

With this Komatsu GD705A-4 Motor Grader Parts Book open, you can identify any assembly or sub-assembly on the machine, pull the exact part number for the piece you need, check the quantity used, confirm whether a newer or interchangeable number replaces the original, and see whether the part is supplied on its own, as a kit or only as a complete assembly. It supports engine work, power-train and transmission work, hydraulic and steering repairs, control and frame work, blade and drawbar replacement, and the everyday business of keeping a working motor grader in service. Every diagram is a reference you can zoom into on a phone, tablet or laptop, and every page can be printed for the workshop bench.
