23A-70-13130 ADJUSTER KOMATSU

The 23A7013130, 23A-70-13130 ADJUSTER KOMATSU is publicly listed as ADJUSTER, R.H. and is consistently tied to Komatsu motor grader work-equipment assemblies rather than engine, transmission, or undercarriage groups. Catalog and aftermarket references place it in circle support, blade and circle support, and circle drawbar support / circle reverse sections, which makes it a grader implement-control component used around the moldboard-circle support area.

From the uploaded banner image, this part has the visual profile of a heavy cast-and-machined right-hand adjuster with a large pivot bore, reinforced triangular body, a central mounting boss, and a toothed adjustment face. That geometry is consistent with a component designed to help set, retain, or fine-tune the position of connected circle-support hardware on a grader, where strength, repeatable alignment, and resistance to shock loads matter more than cosmetic finish. The image also suggests this is a side-specific piece rather than a universal bracket.

What the 23A-70-13130 adjuster does

Komatsu’s grader documentation describes the circle as the structure that supports blade rotation, while the drawbar and circle support assembly carries and controls that rotating workgroup. A Komatsu grader brochure describes the circle as a forged ring with replaceable support-shoe wear surfaces and 360-degree hydraulic circle reversing control, while a grader patent explains that the circle support mounts the circle and blade for rotation about an upright axis. In that context, an adjuster in the circle-support group is there to help maintain proper positioning and support conditions within a mechanism that is constantly working under load, vibration, and rotational force.

In practical terms, this means the 23A7013130 adjuster is not just a simple hanger or spacer. It belongs to the group that helps the grader’s blade-support assembly stay properly controlled while the circle rotates, the moldboard changes angle, and the machine works across hard-packed roads, rocky cuts, and uneven surfaces. Because Komatsu graders rely on the circle-support system to keep the blade working accurately, even a relatively compact adjuster like this plays an important role in precision grading, wear control, and long-term stability.

Why this part matters on Komatsu motor graders

On a motor grader, blade performance depends heavily on how well the circle, drawbar, and support hardware work together. Komatsu’s grader literature highlights the circle support shoes, replaceable wear surfaces, and hydraulic circle reverse system because these are critical to keeping the moldboard controllable under real jobsite loads. When a support-side adjustment component wears, loosens, or loses correct alignment, the operator may feel it through reduced grading precision, uneven circle support, extra play, or accelerated wear in related support pieces.

That is why buyers looking for 23A-70-13130 are usually not shopping for a cosmetic repair. They are usually solving a real implement-support issue on a grader that still needs to hold its blade accurately. In road maintenance, finish grading, ditch shaping, and slope work, small changes in circle-support fit can affect how confidently the operator holds line, angle, and finish quality. A correctly matched adjuster helps restore the mechanical integrity of that support zone.

Product identity and catalog position

Multiple public references identify this part number as a right-hand adjuster. The main 3GENEXPORT listing shows the exact number 23A-70-13130 and connects it to Komatsu grader catalog pages for circle support and blade-and-circle-support sections. 3GEN also lists the same code as ADJUSTER R.H. for Komatsu graders, and 3GEN places it under Circle Drawbar Support and Circle Reverse for GD511. Together, those sources strongly support the same mechanical identity.

This matters for SEO as well as sales accuracy. Buyers may search 23A-70-13130, 23A7013130, ADJUSTER R.H., Komatsu grader adjuster, or circle support adjuster. A strong product page should therefore carry both number formats, the plain-language part name, and the likely grader application group so that workshops, traders, fleet buyers, and procurement teams can all reach the correct page through their own search habits.

Compatible Komatsu models

Public catalog and aftermarket references consistently associate this adjuster with the following Komatsu grader models:

• GD505A-3
• GD510R-1
• GD511A-1
• GD611A-1
• GD621R-1
• GD661A-1

A separate aftermarket source also lists compatibility with GD505A, GD510R, GD511A, and GD611A in simplified model format, which supports the same core machine family even where the serial-format notation is shortened.

Some additional aftermarket references associate 23A-70-13130 with GD663A-2 as well. Because that fitment is not as consistently shown across the main catalog mirrors as the six models listed above, the safest professional approach is to treat GD663A-2 as a serial-verification application rather than a blanket fitment claim.

There is also an important serial nuance on GD505A-3. One scanned GD505A-3 parts-manual copy shows 23A-70-13130 as the right-hand adjuster for SN 1001–1001, while later GD505A-3 serials use 23A-70-13160 instead. That is exactly why old part number, machine model, and serial number should always be checked before order confirmation.

Technical details and specification summary

The publicly visible specification details for this part are limited, but the available catalog information is still useful for buyers who need a reliable summary:

• Part number: 23A-70-13130
• Alternative search format: 23A7013130
• Catalog description: ADJUSTER, R.H.
• Application group: Circle Support / Blade and Circle Support / Circle Drawbar Support and Circle Reverse
• Machine type: Komatsu motor grader
• Catalog reference weight: 30 kg

That 30 kg value appears in catalog snippets for GD511A-1, GD621R-1, and GD505A-3 application pages, so it is reasonable to present it as the catalog weight reference for the part itself. As always with export logistics, final packed shipping weight can be higher depending on crate size, packing timber, and protective materials.

Build features visible in the uploaded image

The uploaded image is commercially helpful because it shows several features buyers care about before requesting a quote. First, the part has a substantial pivot-bore area, which suggests that it is designed to work with pins, collars, or bushings rather than simply bolt flat to a plate. Second, the main arm is reinforced with a broad triangular web, a shape commonly used where a component needs to resist bending and repeated directional loading. Third, the upper toothed section indicates a positive-contact adjustment interface rather than a smooth sliding face, which is exactly the kind of detail many workshop buyers want to inspect visually before ordering.

The finish and machining details in the image also support the idea that this is a serious implement-side replacement part rather than a rough placeholder item. The bore area appears machined, the mounting surfaces look defined, and the toothed face appears intentionally formed for controlled engagement. For a grader support adjuster, those are the areas that matter most because they influence fit, repeatability, and wear behavior in service.

Why correct adjustment components protect the grader workgroup

Komatsu grader brochures make it clear that the circle and its support system are built to take real load, with hardened teeth, support shoes, and rotating control built into the design. A component placed in that support chain has to contribute to keeping the circle assembly properly retained and correctly positioned. If the wrong part number is fitted, or if a worn adjuster is left in service too long, the result can be misalignment, unwanted looseness, faster wear in related guides and collars, and reduced consistency at the blade edge.

That is especially important on graders because the blade is the machine’s profit center. The engine, transmission, and tandem drive move the machine, but the circle-and-blade assembly is what actually produces finish, crown, slope, and clean material flow. Components like the 23A7013130 right-hand adjuster are small compared with the whole grader, but they help protect the accuracy and stability of the system that does the real shaping work.

Buying advice for 23A7013130

When sourcing this part, the best practice is to confirm:

• full machine model
• serial number
• old part number on the removed component
• whether the machine uses circle support or blade-and-circle-support configuration
• whether related collars, guides, washers, or pins also need replacement

That last point matters because public catalog pages show this adjuster alongside guides, collars, pins, washers, and support parts in the same assembly. In other words, it is part of a system, not an isolated bolt-on item. If the adjuster has worn because of play elsewhere, replacing only one piece may not fully restore the intended fit.

SEO value of this product page

This part has excellent search value because it can be searched in several different ways:

• 23A-70-13130
• 23A7013130
• ADJUSTER R.H.
• Komatsu grader adjuster
• circle support adjuster Komatsu
• GD511 adjuster
• GD621R circle support adjuster

A page that combines the exact part number, the part-name variant, application wording, model list, and a useful mechanical explanation is more likely to perform well not only in traditional search but also in AI-assisted product discovery. That is because buyers searching through Google or Search GPT are often trying to answer several questions at once: what the part is, where it fits, what it does, and whether the supplier understands the application. This page structure helps answer all four.
