23B1512360, 23B-15-12360 CARRIER KOMATSU

The 23B1512360, 23B-15-12360 CARRIER KOMATSU is a heavy internal transmission component used in Komatsu grader applications. Public parts sources place this number in the transmission second-clutch section and list its weight at 6.92 kg, which immediately shows that this is a serious driveline part rather than a light support item.

From the uploaded images, this part has the visual structure of a carrier body designed for rotating internal service. It combines a large machined mounting flange, a raised gear-like outer ring, multiple drilled and threaded holes, and an open center structure that reduces excess mass while preserving rigidity. That design fits well with the public catalog placement in the second-clutch assembly, where supported rotating members need accurate positioning and stable geometry.

For workshops, rebuilders, and fleet owners, the 23B1512360, 23B-15-12360 CARRIER KOMATSU matters because transmission work is expensive in labor, downtime, and risk. Once the gearbox is open, buyers are not simply replacing a named item from a list. They are protecting the whole repair schedule and trying to restore internal stability before the machine goes back to work.

At 3GEN Export, we supply this part as an OEM supplier for professional buyers who need dependable sourcing and worldwide delivery in 5 working days.

Product Overview

Public listings use both number styles, 23B-15-12360 and 23B1512360, and treat them as the same Komatsu carrier part. That matters for search visibility because some buyers work from hyphenated catalog data while others search the compact numeric format from invoices or stock systems. A strong e-commerce page should support both naturally so that qualified buyers can find the product regardless of how the number is written.

The most useful technical clue is the assembly location. Public parts catalogs place this component in the transmission second-clutch group for several Komatsu grader models, including GD605A-5, GD625A-1, and GD661A-1. That means the part works in an active internal clutch-related section rather than in an exterior housing area or non-rotating bracket position.

That context makes the role of the 23B1512360, 23B-15-12360 CARRIER KOMATSU much clearer. A carrier in a second-clutch assembly has to do more than fit physically. It must hold alignment, resist distortion under load, and support the working relationship between nearby transmission elements over long service cycles. When a part in this position loses dimensional accuracy, the resulting problem can affect neighboring pieces through poor contact patterns, unstable rotation, and uneven wear. That is a practical mechanical inference from the documented clutch-group location and the type of components listed around it in public parts diagrams.

What This Part Does in the Transmission

Based on public catalog placement, this carrier belongs to the second-clutch section of the grader transmission. In practical terms, that means it functions as an internal support and positioning member within a clutch-related rotating assembly. Its job is not decorative and it is not passive. It belongs to a working part of the driveline where correct internal relationships directly affect how the transmission behaves under load.

The surrounding catalog context is important here. Public assembly pages for the same group show nearby gears, bushings, discs, and plates in the second-clutch system. That strongly suggests that the carrier helps locate and support internal elements that must remain in precise relationship to one another while the grader operates.

In field service, that matters because a grader transmission sees repeated load changes, vibration, long operating hours, and continuous oil-lubricated motion. A carrier body in this environment has to remain rigid and dimensionally stable. If it wears, cracks, or deforms, the effect rarely stays isolated to one surface. The surrounding clutch hardware may begin to show abnormal contact or premature wear as well. That is why buyers usually search this part during real repair work, not just general stock browsing.

Visual Analysis of the Uploaded Images

The uploaded photos help confirm the mechanical identity of the part and make the listing much more useful for technicians.

Broad mounting flange

The lower flange is large, evenly machined, and drilled with a ring of threaded holes. This immediately suggests fixed installation into a larger transmission assembly. Parts that work in rotating clutch groups often rely on this kind of flange to maintain repeatable mounting and accurate alignment.

Fine external tooth ring

One of the most visible features is the narrow, evenly spaced toothed outer circumference. That detail indicates an active mechanical relationship with surrounding internal hardware. The teeth are too deliberate and too uniform to be ornamental. They point to a real driveline function.

Open structural center

The open window areas between the upper ring and lower flange show a carrier-style design choice. They reduce unnecessary mass while preserving enough strength for internal support duty. This is one of the strongest visual signs that the 23B1512360, 23B-15-12360 CARRIER KOMATSU is not just a plain gear disc or spacer.

Machined bores and seating surfaces

The multiple machined holes and smooth contact faces indicate that precision matters. Even without assigning a factory-defined purpose to each individual bore, the layout clearly shows that this is an assembly-specific part with controlled mounting and support points.

Compatible KOMATSU Models

Public references connect this part number with several Komatsu motor grader applications. The clearest serial-based listings I found include these models and ranges: GD605A-5 S/N 1001-UP, GD605A-5S S/N 4001-UP, GD611A-1 S/N 10001-UP, GD621A-1 S/N 10001-UP, GD621R-1 S/N 10001-UP, GD623A-1 S/N 30001-UP, GD625A-1 S/N 50001-UP, GD625A-1 S/N 60001-UP for North America, GD661A-1 S/N 10001-UP, and GD663A-2 S/N 1001-UP.

For website presentation, the compatible family list can be shown like this:

Komatsu GD605A

Komatsu GD611A

Komatsu GD621A

Komatsu GD621R

Komatsu GD623A

Komatsu GD625A

Komatsu GD661A

Komatsu GD663A

These model associations are supported by public parts sources, but serial-number verification remains the safest final step before purchase because clutch-group transmission parts are often range-sensitive.

Weight and Technical Details

Public catalog references list the weight of 23B-15-12360 at 6.92 kg. Because that figure appears consistently in multiple parts references, it is the strongest practical published weight for quoting, shipping, and warehouse planning.

Why the 23B1512360, 23B-15-12360 CARRIER KOMATSU Matters in Real Repairs

A transmission repair is never only about replacing one named item. Once the gearbox is open, the cost of labor, inspection time, and machine downtime becomes part of every purchasing decision. That is why the 23B1512360, 23B-15-12360 CARRIER KOMATSU matters so much to serious buyers. It is positioned inside a clutch-related transmission section where accurate support and internal alignment influence the durability of the surrounding assembly.

In real grader work, second-clutch hardware sees repeated operational cycling, changing traction conditions, and long hours under load. A component in this position must resist distortion and maintain its geometry through all of that. A part that looks correct but does not hold alignment properly can shorten the life of nearby gears, bushings, or clutch elements. That is the practical reason experienced workshops treat this kind of carrier as a real transmission repair part rather than a simple hardware item.

Buying Guidance

The best heavy-equipment product pages help buyers avoid mistakes before the order is placed.

Support both number styles on the page. Buyers search 23B-15-12360 and 23B1512360 in different systems, so both should appear naturally in the listing.

Confirm the assembly section. This is a transmission second-clutch part, not a random housing piece and not a component from a different clutch group. Assembly location matters just as much as the number itself.

Confirm model and serial range before ordering. Public references clearly show serial-specific use across several grader families, especially GD605A-5, GD625A-1, and GD661A-1.

Compare the removed component visually. The uploaded images make it easy to check the flange size, hole pattern, outer tooth ring, and open center design against the part on the bench. That visual cross-check can prevent costly delays.
