23B7351490, 23B-735-1490 GUIDE KOMATSU

Heavy-duty circle support guide for Komatsu grader applications

The 23B7351490, 23B-735-1490 GUIDE KOMATSU is a grader work-equipment component used in the circle supportassembly of Komatsu machines. Public parts references consistently identify this exact number as a Guide and place it in the WORK EQUIPMENT / CIRCLE SUPPORT section for the Komatsu GD625A-1 machine family. That matters because it immediately tells buyers that this is not a random fabricated steel piece. It is a location-specific wear and guidance component designed for the circle support system, where control, alignment, and long-term contact stability are essential for proper grader performance.

For buyers searching by number, both versions should be used naturally across the product page: 23B7351490 and 23B-735-1490. Many technicians type the compact version into dealer systems, while export buyers and search engines often find the hyphenated version more easily. A strong listing should therefore include both search variations together with the full product name 23B7351490, 23B-735-1490 GUIDE KOMATSU. At 3GEN Export, we supply this part as an OEM supplier and support worldwide delivery in 5 working days, helping repair teams and fleet operators reduce downtime when grader circle support components need replacement.

What is 23B7351490, 23B-735-1490 GUIDE KOMATSU?

The 23B7351490, 23B-735-1490 GUIDE KOMATSU is publicly listed as a Guide for Komatsu grader equipment, specifically within the circle support section. Multiple public references connect the part with the GD625A-1 S/N 50001-UP and GD625A-1 S/N 60001-UP (For North America) configurations. That repeated assembly placement strongly indicates that this part is used to guide, stabilize, or control movement inside the grader circle support mechanism rather than serving as a structural body panel or non-contact bracket.

the part has a long fabricated U-channel style profile with a mounting ear at one end. The geometry suggests a controlled sliding or guiding function, which aligns well with the “guide” designation found in public parts catalogs. The body appears designed for wear contact or controlled positional movement, likely helping manage alignment or motion inside the circle support area. supported by the published part classification and assembly references.

Compatible KOMATSU models

Publicly referenced machine applications

The public sources I found clearly connect 23B7351490, 23B-735-1490 GUIDE KOMATSU with the following models and serial ranges:

• Komatsu GD625A-1 S/N 50001-UP
• Komatsu GD625A-1 S/N 60001-UP (For North America)

These are the clearest machine references available in public parts listings for this exact part number. I did not find a trustworthy public source confirming broader fitment beyond these GD625A-1 references, so the safest commercial wording is to list these machines and recommend model and serial number confirmation before ordering.

Assembly location and function

One of the most useful details confirmed by public sources is the assembly location. The part is tied to the CIRCLE SUPPORT section. In a grader, the circle support area is critical because it helps the moldboard and circle assembly maintain alignment during angle changes, rotational positioning, and load-bearing work. A guide in this zone is important because grading accuracy depends on controlled mechanical movement, not just raw hydraulic power. If alignment or support wear becomes excessive, blade control quality can suffer.

That is why 23B7351490, 23B-735-1490 GUIDE KOMATSU is an important service item for fleets that run graders in road construction, site preparation, fine leveling, and municipal maintenance work. Even though it may look simple compared with gears or hydraulic cylinders, a guide part in the wrong condition can affect system stability, increase wear on related components, and reduce the precision operators expect from a Komatsu grader.

Visual Inspection

The product images provide strong visual support for a high-conviction product listing. The part shows a long, formed channel-like body with a smooth painted finish and a mounting tab with a hole at the end. That shape is consistent with a wear guide, track guide, or support guide component rather than a rotating or pressure-containing part.

Channel-style body

The open-channel section is the most obvious visual feature. This kind of structure is useful when a part needs to interface with a mating support, block, or sliding section while maintaining directional control.

Mounting tab

The end tab with a mounting hole indicates positive attachment into a fixed location. This suggests the part is not free-moving by itself but intended to be installed securely as part of a guided system.

Straight wear path geometry

The long straight body gives the impression of a defined contact or guidance length. In practical operation, that usually means more stable support and better contact distribution.

Painted industrial finish

The coating seen in the images is appropriate for heavy machinery spare parts exposed to harsh site conditions, contamination, and moisture during service and storage.

These observations come from the product images and match the public classification of the part as a Komatsu Guideused in the circle support section.

Why 23B7351490, 23B-735-1490 GUIDE KOMATSU matters in grader performance

Graders depend on precision. Unlike some heavy equipment where pure force is the main priority, graders also rely on repeatable blade position, smooth adjustment, and stable support under load. The 23B7351490, 23B-735-1490 GUIDE KOMATSU matters because a circle support guide helps the relevant assembly maintain controlled movement and predictable positioning.

When the guide surface wears, deforms, or becomes loose, operators may begin noticing indirect symptoms such as less precise blade control, abnormal play, noise under movement, uneven contact wear, or faster deterioration of nearby components. These are engineering inferences based on the part’s role as a guide in a grader circle support assembly rather than verbatim service manual statements. They are reasonable because guides are usually installed specifically to manage movement, contact, and positional consistency.

Common replacement scenarios

Wear from long-term contact

Guide components are often exposed to repeated movement, vibration, load transfer, and contamination. Over time, surface wear can reduce the effectiveness of the part.

Distortion or damage

If a grader has experienced abnormal loading, impact, or misalignment in the circle support area, the guide may need replacement to restore proper geometry.

Planned overhaul work

Some workshops replace guide-related wear components during broader circle support service to avoid reopening the assembly later.

Uneven movement or poor adjustment feel

If the circle support system no longer feels smooth or stable during operation, this part may be inspected alongside related supports, shims, and contact surfaces.

These are application-based workshop scenarios inferred from the assembly function and product type.

Material and construction expectations

Although the public sources do not provide a full manufacturer materials sheet, a fabricated metal part with an industrial protective finish. For a component used in a grader circle support environment, buyers expect a combination of the following qualities:

Structural rigidity

The part must resist bending and deformation during service.

Surface durability

Because a guide typically interfaces with contact surfaces, wear resistance is important for long life.

Dimensional accuracy

Alignment parts must fit correctly in order to support reliable grader geometry and motion.

Corrosion resistance through coating

The painted outer finish helps protect the part during storage, handling, and early service life.

These are evidence-based performance expectations drawn from the part category, visible design, and machine application.

Weight

Unlike many similar pages where weight must be guessed, I found a public listing that gives a weight for this exact part number. The source lists the weight of 23B-735-1490 Guide as 2.20 kg.

Weight: 2.20 KG

you can present it as:

Weight: 2.200 KG

That is the strongest available public number I found for this exact part.

Fitment caution

Even with public model references, professional parts ordering should still include serial number verification. Public sources connect this part with:

• GD625A-1 S/N 50001-UP
• GD625A-1 S/N 60001-UP (For North America)

Because grader configurations can change across regions and serial breaks, the safest commercial practice is to confirm the machine serial number before dispatch.
