Komatsu GD705A-4 Motor Grader Parts Book PDF – S/N 21001-UP Illustrated Parts Catalog

Description

This Komatsu GD705A-4 Motor Grader Parts Book is the illustrated parts catalog covering machines from serial number 21001 and up. Every major assembly on the grader is broken down into exploded illustrations with numbered callouts that link directly to part numbers, descriptions, quantities and the serial-number ranges each part applies to. If you need to identify a bracket, a hose, a seal kit, a control lever or a complete assembly for a GD705A-4, this catalog is where the answer is written down.

Read together, these figure groups give you a complete walk-around of the GD705A-4 as a parts system rather than a machine narrative. Mounting hardware for the engine and transmission sits beside the radiator and oil cooler group, which in turn sits beside the fuel and hydraulic tank group, the battery and electrical system, the transmission internals, the final and tandem drives, the wheels, the complete control lever and linkage family, the frames and guards, the cab and canopy options, the air and brake circuits, the whole hydraulic system from pump through valve to cylinder, and finally the work equipment – drawbar, blade, circle support, scarifier, front blade and rear ripper. Each figure carries its own item list with part numbers, descriptions and quantities, plus the serial-number options that tell you whether a given part fits your particular machine build.

How the Catalog Is Organised

Every assembly is presented the same way: an exploded illustration with numbered balloon callouts, followed by a table keyed to those numbers. The table columns give you the item number, the part number, the description, the quantity required and an options column showing the serial-number range each part applies to. Because the GD705A-4 was built across a long production run, many figures show two or three alternative part numbers side by side with their serial-number boundaries – for example the radiator and oil cooler group differs either side of #23001, the instrument panel changes several times across the run, and the hydraulic control levers split between the earlier and later arrangements. You can therefore check a part number against your machine serial before you commit to a purchase, instead of ordering on appearance alone.

Where This Parts Book Pays Off

Reassembly jobs are where an illustrated catalog earns its keep. When a control lever linkage comes apart, when a hose route is unclear, when a shim pack or a spacer has to go back in the right sequence, or when a bracket has to be identified simply by its position on the frame, the exploded figure shows the order and the item list gives the number. The same applies to the hydraulic and air circuits, where elbows, unions, O-rings, gaskets, clamps, bands and clips are all individually listed rather than lumped into a single assembly number. Service kits appear with their own part numbers alongside the individual components they contain, so you can buy the kit or the single piece depending on what the job needs.

For anyone maintaining a GD705A-4 across its full serial range, the value is in the completeness. The catalog runs from the engine and transmission mounts all the way out to the ripper points, covering every option the machine was offered with – air conditioning, car heater, noise suppression, canvas or steel canopy, ROPS cab, front blade, scarifier, rear ripper, blade accumulator and blade float. Whatever configuration your grader is in, its parts group is almost certainly drawn here.
