23S-15-21280 PIN KOMATSU

The 23S-15-21280 PIN KOMATSU is a machine-specific transmission component used in selected Komatsu grader and crane applications. Public parts references connect this part number with reverse clutch assemblies, and catalog data also identifies the alternate search format 23S1521280. For buyers searching by exact code, both formats matter because many procurement systems, dealer-style catalogs, and spare-parts platforms index them separately.

From the product images, this component has the long, slim, straight profile expected from a precision locating or retaining pin rather than a large structural pivot pin. That shape matches the public catalog description that notes a diameter and length format of D=10 and L=285. In other words, the 23S-15-21280 PIN KOMATSU is a compact but important internal transmission part, designed for accurate positioning inside the related clutch group.

For heavy equipment owners, workshop managers, rebuild specialists, and export buyers, this kind of part is usually ordered by exact number rather than by general category. That is because a small mismatch inside a clutch-related assembly can create installation delays, unwanted play, uneven wear, or repeated disassembly. The value of the 23S-15-21280 PIN KOMATSU is therefore not visual complexity, but correct fit, proper seating, and stable performance in the machine’s reverse clutch section.

Product Overview

The 23S-15-21280 PIN KOMATSU appears in public Komatsu parts references under reverse clutch or transmission reverse clutch sections. One catalog entry for GD605A-5 shows it in the reverse clutch group, and another for GD625A-1 places it in the same assembly family. Those listings are useful because they clarify the function of the part: this is not a random hardware pin, but a transmission-related component intended to work inside a specific mechanical arrangement.

The same reference trail also shows that this part may be used in multiple positions within the assembly. One public diagram snippet lists a quantity of five pieces in the reverse clutch group. That detail suggests the pin works as part of a repeating internal layout where uniform length, diameter, and finish matter across several identical positions. For professional maintenance teams, that is an important purchasing point, because overhaul work may require more than one unit at the same time.

Another practical detail is weight. A public application page lists the part at 0.18 kg, which makes it lightweight in shipping terms but still critical in mechanical terms. Small internal components often have an outsized effect on transmission reliability because they help keep surrounding parts aligned during repeated machine operation.

What This Pin Does

The 23S-15-21280 PIN KOMATSU is associated with reverse clutch assemblies, which means its job is tied to alignment, positioning, and repeatable internal movement inside the transmission group. In assemblies like these, even a simple cylindrical pin can be essential for holding parts in their intended relationship under vibration, load change, and repeated directional use. When dimensions drift or a worn part is reused, the result can be extra movement, premature wear, or inconsistent performance over time.

This is exactly why buyers search for 23S-15-21280 PIN KOMATSU by the full part number instead of using generic phrases. A transmission pin must match the intended application precisely. Diameter, length, surface finish, and straightness all influence how the part sits in the assembly. Even when a component looks simple on the outside, the tolerance expectations behind it are not simple at all.

From a service perspective, this Komatsu pin supports dependable assembly geometry. In heavy-duty roadwork, grading, and crane-related operations, machines cycle through demanding conditions that expose transmission components to constant mechanical stress. A correctly matched replacement helps technicians restore the intended internal layout instead of improvising with a near-fit alternative that may create future problems.

Technical Details and Specifications

Part Identification

The main reference number is 23S-15-21280, and the alternate search format is 23S1521280. Public listings name the part simply as a pin, while catalog references place it in reverse clutch-related sections of Komatsu equipment documentation.

Dimensional Reference

Public parts data identifies this item as PIN (D=10 L=285). That indicates an approximate 10 mm diameter and 285 mm length in catalog notation. For online buyers, this is one of the most useful confirmation points because it supports both part-number matching and visual verification against the supplied images.

Approximate Weight in KG

The listed reference weight for this part is 0.18 kg. This is the figure shown on the publicly available application page and is the safest value to use on the product page unless your warehouse has a measured packed weight for its own inventory record.

Compatible Komatsu Models

Public fitment references connect the 23S-15-21280 PIN KOMATSU with the following Komatsu machines:

LW250L-1H
LW250L-1NH
LW250L-1NX
LW250L-1X
GD605A-5
GD605A-5S
GD611A-1
GD621A-1
GD621R-1
GD623A-1
GD625A-1
GD661A-1
GD663A-2

In addition, cross-reference snippets from public parts catalogs associate part 23S-15-21280 with GD605A, GD611A, GD621A, GD621R, GD623A, GD625A, GD661A, GD663A, and LW250L machine families. Because production ranges and serial breaks can affect internal transmission parts, it is still best to confirm by machine serial number before dispatch.

Why Buyers Replace This Part

The 23S-15-21280 PIN KOMATSU is commonly sourced during transmission service, reverse clutch inspection, or preventive rebuild work. Technicians may replace it because of wear, scoring, bending, installation damage, uncertain service history, or because the related clutch section has already been opened and the labor cost of reopening it later is far higher than changing the pin during the current repair.

This is especially true in fleet environments. If one internal locating pin has visible wear, buyers often prefer to replace all matching positions in the same assembly so the rebuilt section starts from a more consistent condition. Since public diagrams show multiple units in at least one reverse clutch layout, quantity planning becomes part of the ordering process rather than an afterthought.

Why This Part Matters on an E-Commerce Page

A strong product page for 23S-15-21280 PIN KOMATSU should do more than repeat the part number. It should help the buyer confirm three things immediately: what the part is, where it is used, and why the exact number matters. Buyers in this category are usually not browsing casually. They are searching after a workshop diagnosis, checking a transmission diagram, matching a removed part, or preparing a purchase request for a repair order.

That is why the best-performing copy balances SEO with technical clarity. The page should include the two searchable number formats, a clear application context, a realistic dimensional note, compatible machine families, and a clean supply message. Overusing the exact phrase weakens readability, so this revised version keeps the part number visible without making the text feel mechanical.
