23B1512741, 23B-15-12741 PISTON KOMATSU

The 23B1512741, 23B-15-12741 PISTON KOMATSU is a transmission-side piston used in Komatsu motor grader applications. Public parts references identify this number as PISTON,HIGH and place it in the transmission (low and high clutch) section, which means it belongs to an internal clutch-related driveline assembly rather than to an exterior hydraulic cylinder or a general engine piston category. Public sources also show the two main search formats, 23B1512741 and 23B-15-12741, as the same part number.

From the uploaded images, the 23B1512741, 23B-15-12741 PISTON KOMATSU has the visual profile of a machined annular clutch piston rather than a combustion-engine piston. The part is flat and circular, with a broad outer face, a central opening, stepped inner surfaces, and evenly spaced mounting ears or tabs around the perimeter. That geometry matches the kind of piston used inside an oil-fed clutch housing, where hydraulic pressure acts across a machined face to move the component axially and engage or release an internal clutch pack.

For buyers, that distinction matters. A high-clutch piston is not a cosmetic spare part and not a random round plate. It is a working transmission component that helps apply force inside the clutch section of the grader transmission. When it wears, scores, cracks, or loses sealing integrity, the result can show up as inconsistent clutch engagement, pressure loss, reduced driveline smoothness, or accelerated wear on related internal parts. The clutch-group placement is directly supported by public catalog references, while the operating consequences are a practical mechanical inference from that placement.

At 3GEN Export, we supply the 23B1512741, 23B-15-12741 PISTON KOMATSU as an OEM supplier for professional buyers who need dependable sourcing and worldwide delivery in 5 working days.

Product Overview

The most useful starting point for this product is the assembly location. Public Komatsu parts sources place the 23B1512741, 23B-15-12741 PISTON KOMATSU in the low and high clutch transmission group on grader models such as GD605A-5, GD625A-1, and GD661A-1. One public listing also describes the part specifically as PISTON,HIGH, which is a stronger and more informative functional label than the shorter generic word “piston.”

That means this part should be understood as a clutch-application transmission piston for Komatsu graders. It is not the kind of piston used in an engine cylinder, and it is not a simple hydraulic ram. It belongs to a compact internal transmission group where oil pressure, clutch discs, springs, plates, and machined sealing surfaces all work together. A related public parts breakdown also shows this number alongside springs, pins, discs, and plate elements in the same transmission section, which reinforces that interpretation.

The 23B1512741, 23B-15-12741 PISTON KOMATSU also benefits from strong search behavior. Buyers may search the hyphenated format from a printed catalog, the compact format from purchasing software, or a spaced version copied from workshop notes. Public sources confirm those number variations are all recognized forms of the same part, so your product page should naturally support them for better search coverage.

What the 23B1512741, 23B-15-12741 PISTON KOMATSU Does

In practical transmission terms, the 23B1512741, 23B-15-12741 PISTON KOMATSU is there to apply hydraulic force inside the high-clutch section. Public sources label it as PISTON,HIGH and place it in the low and high clutch group, which supports the conclusion that it is part of the oil-actuated clutch mechanism rather than a free-spinning gear or passive housing plate.

Inside a grader transmission, a piston in this position typically converts hydraulic pressure into controlled axial movement. That movement helps compress or release clutch elements so torque can be transferred in the intended operating state. The images support this reading: the broad annular shape, inner stepped recesses, and large sealing surface area are exactly the kind of features you expect on a clutch piston designed to move inside a machined bore with controlled oil pressure.

That is why the 23B1512741, 23B-15-12741 PISTON KOMATSU matters during real repair work. If the piston face becomes worn, if sealing surfaces deteriorate, or if the part no longer moves correctly inside the clutch housing, the machine may begin to show engagement problems or unstable transmission behavior. Those service implications are an engineering inference from the documented clutch-group role of the part.

Visual Analysis of the Uploaded Images

The uploaded images help explain the mechanical identity of the part very clearly.

Flat annular body

This is not shaped like an engine piston. The 23B1512741, 23B-15-12741 PISTON KOMATSU has a wide, flat, ring-like body with a central bore. That shape strongly supports use inside a clutch housing where the part must move axially rather than reciprocate in a combustion cylinder.

Machined sealing surfaces

The broad circular faces and concentric steps suggest that sealing accuracy matters. In clutch pistons, these surfaces usually interact with oil pressure and housing bores, so machining quality is critical.

Perimeter tabs and holes

The outer edge includes several evenly spaced lugs or tabs with paired holes. That feature points to controlled assembly positioning and helps separate this part visually from a plain ring or disc.

Balanced, rigid construction

The overall symmetry of the 23B1512741, 23B-15-12741 PISTON KOMATSU shows that it is meant to operate evenly under pressure. A component like this has to stay dimensionally stable to apply force consistently across the clutch system.

Compatible KOMATSU Models

Public sources give two levels of compatibility information for this part.

The strongest fitment evidence comes from the direct transmission catalog references. These show the 23B1512741, 23B-15-12741 PISTON KOMATSU in the low-and-high-clutch transmission section for:

• Komatsu GD605A-5 S/N 1001-UP

• Komatsu GD611A-1 S/N 10001-UP

• Komatsu GD621A-1 S/N 10001-UP

• Komatsu GD625A-1 S/N 60001-UP for North America

• Komatsu GD661A-1 S/N 10001-UP

Broader public cross-reference results also mention additional grader families such as GD511A, GD521A, GD525A, and GD663A in connection with this number. Those broader results are useful for search and research, but they are not as precise as the serial-specific clutch catalog pages above, so they should be treated as cross-reference guidance rather than final fitment proof.

For your product page, the safest wording is this: the 23B1512741, 23B-15-12741 PISTON KOMATSU is publicly linked to multiple Komatsu grader transmission applications, especially GD605A-5, GD611A-1, GD621A-1, GD621R-1, GD623A-1, GD625A-1, and GD661A-1, with serial verification recommended before order.

Why This Part Matters in Real Repairs

The 23B1512741, 23B-15-12741 PISTON KOMATSU matters because transmission repairs are expensive in labor, downtime, and risk. Once a grader transmission is open, every clutch-related component has to justify its reuse. A piston that shows wear, distortion, or sealing damage can undermine the whole clutch pack even if the surrounding parts still look acceptable.

In real grader work, the transmission sees repeated load changes, direction changes, and long service hours. A high-clutch piston in that system has to move correctly, apply force evenly, and hold its working geometry over time. If it does not, the result can be larger than one failed part. It can affect clutch engagement quality and accelerate wear elsewhere in the assembly. That is why serious buyers treat this as a real driveline repair component, not a casual stock item. The exact role as PISTON,HIGH in the low-and-high-clutch group is directly supported by public sources.

The 23B1512741, 23B-15-12741 PISTON KOMATSU is especially relevant for workshops and rebuilders because it sits inside a section where related parts are already highly integrated. Public parts breakdowns place it near springs, discs, and plates, which means it belongs to a compact group of interdependent hardware. When one part in that group becomes suspect, the safest repair approach is often to evaluate the whole clutch area rather than only the most obviously damaged item.

Buying Guidance Before Ordering

The first rule is to match both part-number styles. Buyers search 23B1512741 and 23B-15-12741 in different systems, and both are publicly recognized formats for the same piston.

The second rule is to confirm the assembly group. This is a high piston in the low and high clutch transmission section, not a reverse-clutch piston and not a general hydraulic piston. That distinction matters because nearby Komatsu transmission parts can have very similar naming while serving a different internal role.

The third rule is to confirm the exact machine model and serial range. Public sources show serial-specific use on GD605A-5, GD611A-1, GD621A-1, GD621R-1, GD623A-1, GD625A-1, and GD661A-1. That makes serial verification the safest final step before purchase.

The fourth rule is to compare the removed part visually. The uploaded images make it easy to check the annular body shape, stepped surfaces, and tab layout against the workshop part on the bench before ordering.
