2347012151, 234-70-12151 BLOCK KOMATSU

The 2347012151, 234-70-12151 BLOCK KOMATSU is best documented online as a circle support block used on Komatsu motor graders. Public parts sources identify the part name as Block, place it in the circle support area, and list its weight at about 0.872 kg, while other supplier listings round it to 0.87 kg.

That classification is important because the circle support zone is one of the core working areas on a grader. It is directly related to how the moldboard circle is supported, guided, and kept stable during rotation and angle changes. A supplier page for this exact part also markets it specifically as a Komatsu 234-70-12151 circle support block, which strongly reinforces that application.

Based on the uploaded images, this part does not look like a random rectangular spacer. It appears to be a compact wear or support block with a central mounting hole, stepped guide faces, and a shaped profile designed to sit in a working contact area. That visual geometry fits very well with the public description of the part as a circle support block for grader blade-and-circle systems.

What the 2347012151, 234-70-12151 BLOCK KOMATSU does

The most practical way to understand this part is as a support and wear component inside the grader’s blade-and-circle assembly. Public catalog references place it in circle support, while one machine-specific listing places the same number under Blade and Circle for a Komatsu grader. That tells us this block belongs to the work-equipment side of the machine rather than to the engine, transmission, or axle groups.

On a motor grader, the blade circle must stay supported while the operator changes moldboard angle and working position. That means the contact points around the circle-support structure need parts that can stabilize load, guide movement, and absorb wear over time. A compact component such as this block may not look dramatic, but in real service it helps protect larger surrounding parts and supports more predictable circle behavior.

That matters because graders depend on controlled blade positioning more than almost any other earthmoving machine. The quality of the finished road surface, shoulder line, ditch angle, or grading pass depends on how accurately the machine can manage the moldboard. A part used in the circle support area therefore has direct value in machine precision, even if it is small and relatively simple. Public sources placing this number in circle support and blade-and-circle assemblies support that interpretation clearly.

Why this circle support block matters in real grading work

A grader does not earn its value from raw pushing power alone. It earns its value from control, repeatability, and surface quality. When the circle-support zone becomes worn or inconsistent, the blade assembly can lose some of its smoothness and stability. Even minor wear parts in that area can influence how the machine feels in long passes and fine corrections.

The 2347012151, 234-70-12151 BLOCK KOMATSU is the kind of part that helps prevent wear from spreading deeper into the blade-and-circle system. Instead of allowing more expensive support surfaces to take direct damage, a replaceable block can act as a working contact component inside the assembly. That makes it commercially important for preventive maintenance, not just emergency repair. The fact that public listings consistently place the number in circle support and blade-and-circle categories is what makes that maintenance logic credible.

For workshop teams, that means this block is not just a small catalog item. It is part of the system that helps keep circle movement stable. For fleet owners, it means a relatively low-weight part can still influence service quality and repair cost. For resellers, it means the part has strong search value because buyers look for it by exact number, by machine model, and by its functional name, “circle support block.”

Design review based on the uploaded images

Compact but purpose-shaped body

The uploaded images show a part with a rectangular outer form, but the body is not plain. One side has shaped stepped faces, and the other shows a central bore through the block. That suggests a part designed to mount securely and interact with a moving or supported surface, not simply sit as a dead spacer.

Central mounting hole

The through-hole is one of the most important visual details. It strongly indicates that the block is fixed into position with a bolt or pin while the surrounding surfaces guide or support movement. That matches the public classification of the part as a block in the circle support area.

Profiled working faces

The stepped and relieved faces visible in the product photos look engineered for contact and alignment. They appear meant to sit against or around adjacent structural members in a predictable orientation. In heavy machinery, that usually points to a wear, guide, or support function rather than decoration or simple packing.

Heavy-duty finish

The painted yellow coating gives the part a clear heavy-equipment presentation and protects the exterior surface in storage and handling. The part also appears dense and solid for its size, which fits the public weight data in the 0.87 kg range.

Compatible KOMATSU models for 2347012151, 234-70-12151 BLOCK KOMATSU

The clearest public fitment list I found for this exact number includes the following Komatsu motor grader models:

• GD305A-1A
• GD405A-1
• GD505A-2
• GD510R-1
• GD511A-1
• GD521A-1
• GD521A-1E
• GD605A-3
• GD611A-1
• GD621A-1

There are also additional public seller references that mention the same number with GD661 and GD705R-1 applications, and one search result summary links the part more broadly with grader families such as GD355A and GD500R. Those are useful secondary signals, but the most solid open fitment list remains the ten model references shown above. Final fitment should still be confirmed by machine serial number and parts documentation before order placement.

Why buyers search this part in different ways

This is exactly the kind of industrial spare that gets searched under several patterns. A parts manager may enter 2347012151 from ERP data. A mechanic may type 234-70-12151 from a printed catalog. A trader may search Komatsu circle support block after identifying the function from a machine diagram. Supplier pages themselves reflect this behavior by using both number styles and the functional term “circle support block.”

That is why the best SEO structure for this product page is not to repeat the exact keyword unnaturally in every paragraph. The strongest approach is to keep the full product name visible in the title, opening section, technical area, fitment section, summary, and metadata, while using natural supporting phrases such as Komatsu circle support block, grader blade-and-circle block, circle support spare part, and motor grader support block throughout the body.

Why the 2347012151, 234-70-12151 BLOCK KOMATSU matters in maintenance planning

Circle-support wear often develops gradually. Operators may first notice it as less crisp blade response, more play in the circle-support area, or reduced confidence in fine grading work. Because of that, parts like this are useful not only in breakdown repair but also in planned maintenance.

For workshops, replacing a worn support block before surrounding parts are damaged is often the smarter repair path. For fleet owners, that helps protect larger circle-support components and may reduce long-term service costs. For distributors, it makes this part commercially valuable because it is small enough to stock easily but important enough to be needed in real grading repairs. Public sources tying the number to circle support, blade-and-circle sections, and multiple Komatsu grader models support exactly that maintenance role.
