23A4612520, 23A-46-12520 CAP KOMATSU

The 23A4612520, 23A-46-12520 CAP KOMATSU is a Komatsu grader spare part publicly identified as a cap and linked to frame-related applications in several parts references. Public seller and catalog sources associate this number with rear-frame usage on grader models such as GD505A-3, GD505A-3A, GD525A-1, and GD661A-1, while another grader-parts seller connects the same number with circle drawbar support and circle reverse on GD655. Taken together, those references strongly suggest a structural retaining cap rather than a filler cap, plug, or cosmetic cover.

A public seller page from 3GENEXPORT lists the weight as 5.2 kg and places the part in the Frame and Body category, specifically under Other Frame and Body Parts. Another marketplace-style listing shows a higher number, but the clearest directly published seller weight I could verify is 5.2 kg, so that is the safest primary figure to display while still confirming packed weight before dispatch.

From the uploaded images, the part does not look like a simple closing plug or thin stamped guard. It has a heavy bridge-style curved body, two mounting holes, thick side walls, and a shaped inner radius that appears designed to sit over or around a larger cylindrical or pivoting component. In practical service terms, that makes it look like a retaining or support cap intended to hold a pin, bushing, shaft seat, or structural support member in position.

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

Product Overview

The biggest challenge with a part like this is that the word cap is not descriptive enough on its own. In heavy equipment, that word can refer to anything from a pipe cap to a structural retainer. Public sources make the situation clearer by consistently placing this number in frame-related rather than fluid-system or engine-side categories. 3GENEXPORT lists it under Frame and Body. The 3GEN result connects it with rear-frame schemes. The stronger public signal is therefore structural machine-frame usage, not a sealing plug or service lid.

That context matters for buyers because category placement often reveals function even when the short name does not. A part that appears in rear-frame groupings and is sold through frame-and-body sections is usually expected to help retain, clamp, or support a loaded mechanical connection. This is especially true when the photographed part has a strong curved profile and a two-bolt fixing pattern rather than threads, tabs, or a sealing flange.

Another useful market clue comes from 3GENEXPORT, which labels 23A-46-12520 for Komatsu grader GD655 and places it in the circle drawbar support and circle reverse area. That phrasing is not identical to the rear-frame wording from the other references, so it should not be treated as a universal final definition. Still, it points in the same broad direction: this number belongs to a structural grader assembly, not a light-duty accessory.

What This Part Likely Does

Based on the public frame-side application references and the visible design in the uploaded images, this component most likely functions as a retainer or support cap in a grader structure that carries meaningful load. A part with this shape usually sits across a circular seat or support point and uses two bolts to hold another member in place. In workshop terms, that often means helping secure a pin, bushing, pivot point, or support element so that movement remains controlled and the surrounding parts wear evenly.

This interpretation becomes more believable when combined with the broader public application context. The 3GENEXPORT result ties the number to rear-frame schemes. 3GEN places it in frame-and-body parts. Another seller links it to circle-support related areas. Those are not the kinds of categories where buyers would expect to find a decorative or low-duty cap. They are categories where retention, alignment, and structural stability matter.

In real grader service, a retention piece in one of these areas can play a larger role than its simple shape suggests. If a cap is bent, cracked, worn at the contact surface, or incorrectly machined, the surrounding support point may begin to move more than intended. Once that happens, nearby bushings, pins, or bracketed frame members can develop uneven wear. That engineering explanation is an inference from the documented frame-related use of the part and from the robust bridge-style geometry visible in the images.

Visual Analysis of the Uploaded Images

Bridge-shaped body

The first thing that stands out is the broad curved form. The part is not flat and not round. It has a defined arch that appears meant to pass over a circular or semi-circular support zone.

Two-bolt retention layout

There is one mounting hole on each end. That means the part is designed to be clamped down in a simple but strong way. This is a classic layout for retaining caps that hold a support member inside a structural assembly.

Thick cross-section

The section thickness is substantial. That tells a buyer the part is meant to resist load rather than just cover an opening. It has the mass and shape of a structural retainer.

Smooth finished faces

The visible surfaces are clean and even. That usually indicates the part must sit flush against a mating face. In heavy-machine frame assemblies, that matters because uneven seating can introduce movement and premature wear.

Compact, purposeful design

Nothing in the shape looks decorative. The geometry is minimal and functional, which is exactly what buyers expect from a grader frame retention component.

Compatible KOMATSU Models

The strongest publicly visible machine references for this number point to Komatsu grader applications. The 3GENEXPORT result links the part to GD505A-3A and rear-frame usage, and public seller references also associate it with GD505A-3, GD525A-1, and GD661A-1. 3GENEXPORT presents it as a Komatsu spare part in frame-and-body applications, while market references extend the grader-family relevance more broadly.

The clearest model references supported by the available public evidence are:

GD505A-3
GD505A-3A
GD525A-1
GD661A-1

Broader public market references also point toward GD521A, GD611A, and GD655 in related grader contexts, but those should be treated as secondary fitment guidance rather than primary catalog-grade confirmation. For a professional product page, the safest wording is that the part is publicly linked to several Komatsu grader families and should be confirmed by exact model and serial number before order.

Weight and Handling Information

The clearest directly published seller weight I verified is 5.2 kg from 3GENEXPORT. That source also places the part in the Frame and Body category and identifies the OEM number as 23A-46-12520. Because another marketplace-style listing shows a higher value, the safest commercial presentation is to use 5.2 kg as the primary published figure and confirm the final packed weight before shipment.

For your website, this is the safest weight section to show:

Part weight: 5.2 kg
Shipping note: packed weight should be confirmed before dispatch.

That format is useful because it gives the buyer a working technical number without pretending there is perfect cross-market uniformity in every listing.

Technical Details and Specification Summary

The strongest practical summary for this item comes from combining the public category references with the visible engineering of the uploaded images. Publicly, the number is identified as a Komatsu cap used in frame-related machine sections. It is listed under Frame and Body, and public references connect it to rear-frame or closely related grader support assemblies.

From the image side, the part can be described as a heavy curved retaining cap with two fastening holes, a bridge-like profile, and an inner arc designed to sit over a cylindrical or supported member. Those are exactly the details a technician wants to compare against the removed workshop part before approving a purchase.

Why This Part Matters in Real Repairs

A part like this may look simple on the bench, but simple-looking structural retainers often have a direct effect on long-term machine stability. In a grader frame or circle-support area, a cap can help keep a support member seated, distribute clamping load, and prevent unwanted movement at a connection point. If that cap is damaged or incorrectly matched, the surrounding joint may begin to shift, and once movement begins, adjacent wear usually accelerates.

That is why the 23A4612520, 23A-46-12520 CAP KOMATSU should not be treated like a generic hardware item. Public sources already place it in grader frame-related contexts, and the visible design supports a structural role. In practical repair terms, replacing the correct retainer helps protect the larger, more expensive components around it.

This is especially important on motor graders because they work under constant vibration, variable blade loads, and long-duty cycles over uneven surfaces. A structural retention part in that environment has to hold its shape and maintain reliable seating under repeated stress. That is why buyers searching for this number are usually solving a real mechanical problem, not just restocking a shelf.

Buying Guidance Before Ordering

Match both number formats during search and procurement. Buyers use both 23A4612520 and 23A-46-12520, and public listings recognize both styles.

Confirm the machine section before ordering. Public evidence places this number in frame-related grader use, not in fuel, lubrication, or fluid-service categories.

Verify by model and serial number whenever possible. The strongest exact references point to GD505A-3, GD505A-3A, GD525A-1, and GD661A-1, while broader grader-family guidance exists but is less precise.

Compare visually before purchase. The uploaded images make it easy to check the arc, thickness, hole spacing, and side profile against the removed part.
