23B2211100, 23B-22-11100 BEVEL GEAR ASSY KOMATSU

The 23B2211100, 23B-22-11100 BEVEL GEAR ASSY KOMATSU is a final-drive gear set for Komatsu motor graders. Public parts catalogs place this number in the FINAL DRIVE GEAR (1/2) group, including differential-lock and no-spin differential variants, and catalog references show a listed part weight of 27.592 kg. Other public listings describe the same part as a bevel gear set or pinion and gear assembly, which matches the uploaded images very closely.

From the uploaded images, this is clearly a matched ring-and-pinion style assembly rather than a loose single gear. The set includes a large spiral bevel ring gear and a mating pinion shaft with a splined end, which is exactly the type of geometry used to transfer torque through a grader final drive or differential-side gear train. Public seller pages also tag this number with terms like crown wheel, crown pinion, bevel gear set, and final drive, reinforcing that this is a complete power-transfer assembly rather than a simple service ring.

For real buyers, that matters immediately. A bevel gear assembly is not a cosmetic or low-priority item. It sits in one of the most load-sensitive areas of the driveline, where tooth contact pattern, shaft fit, and gear-mesh stability directly affect traction, noise, heat, and service life. If this kind of set is worn, chipped, misaligned, or incorrectly matched, the surrounding final drive components can suffer quickly. That practical explanation is a mechanical inference based on the part’s public placement in final-drive gear groups and on the visible ring-and-pinion construction in the images.

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

Product Overview

Public references give a strong foundation for understanding what this assembly is. 3GENEXPORT listing identifies 23B-22-11100 as BEVEL GEAR ASS’Y, shows it in FINAL DRIVE GEAR (1/2), and describes it as a Pinion and Gear Assembly. 3GENEXPORT lists it as Komatsu 23B-22-11100 Bevel Gear Set, while related category tags on that page include final drive, crown wheel, and crown pinion. Taken together, those sources show that this is a matched final-drive bevel set used in Komatsu grader applications, not a loose replacement pinion or standalone ring gear.

That classification is important because the simple name “bevel gear assy” can still hide a lot of technical meaning. In practical workshop language, the part is the gear pair that changes torque direction and ratio inside the final drive or differential-related section. The large ring gear carries the driven side of the mesh, while the pinion shaft engages it at an angle. The uploaded images make this easy to recognize, and the public sources support that interpretation through both naming and category placement.

Another useful point for a strong product page is search behavior. Buyers may search the exact catalog form 23B-22-11100, the compact ERP-style format 23B2211100, or even the spaced version 23B 22 11100. Public seller pages and catalog results explicitly surface those variants, so a well-built listing should include them naturally without repeating the full keyword excessively.

What This Assembly Does

In operating terms, this bevel gear set transfers rotational force through the grader final-drive section. Public parts catalogs place it in final-drive gear diagrams for machines such as GD505A-3, GD521A-1E, and GD661A-1, which means the assembly belongs to a loaded driveline group rather than a static support structure.

A ring-and-pinion set like this has to do several jobs at once. It must carry torque cleanly, maintain a consistent tooth contact pattern, resist shock loading, and stay dimensionally stable under heat and continuous load. If tooth wear becomes uneven or if the shaft or bearing support geometry changes, the machine may begin to show noise, vibration, heat buildup, backlash, or accelerated wear in neighboring final-drive components. Those performance effects are engineering inferences from the documented final-drive role of the part and the visible matched gear-set design.

This is also why buyers do not usually search this number casually. A component in the final drive is normally sourced when a grader is already under serious driveline service or when a teardown has already identified ring-and-pinion wear. Public seller tags such as final drive, crown wheel, and crown pinion support that real-world repair context.

Visual Analysis of the Uploaded Images

Large spiral bevel ring gear

The ring gear in the images has a broad circular body and deep spiral-cut teeth. That tooth form is designed for angled mesh with a mating pinion rather than straight-line spur engagement. The size of the ring also shows that this is the torque-carrying half of a serious final-drive set, not a light auxiliary gear.

Matching pinion shaft

The mating pinion is integrated with a shaft section and ends in a splined drive portion. That tells a technician two important things immediately. First, this is a matched set rather than a random gear assortment. Second, the pinion is designed to connect positively to a shaft-side drive interface, which fits the public final-drive classification very well.

Precision-machined bearing and seat areas

The shaft section shows stepped machined surfaces and defined seat areas near the pinion. Those features are exactly what you expect where bearings, shims, and preload-related hardware have to control mesh position. Even without over-claiming factory dimensions, the images show a part built for precise driveline setup.

Matched tooth geometry

Both gears present as a coordinated pair. The tooth form, size relationship, and overall finish indicate that the ring and pinion are intended to work together as one set. That matters because replacing only one side of a final-drive pair is often risky in real service conditions.

Compatible KOMATSU Models

Publicly visible model references for 23B-22-11100 are strongest for Komatsu grader applications. Seller and catalog sources connect this number with GD505A-3, GD505A-3A, GD521A-1, GD521A-1E, GD525A-1 / GD525A-1C, GD611A-1, GD661A-1, and in some marketplace references GD663A-2. Shop & Supply specifically lists GD521A-1, GD521A-1E, GD525A-1C, GD611A-1, and GD661A-1, while broader parts-directory pages add GD505A-3 and GD505A-3A.

The most reliable machine families to publish on your page are:

GD505A-3
GD505A-3A
GD521A-1
GD521A-1E
GD525A-1 / GD525A-1C
GD611A-1
GD661A-1
GD663A-2

For a professional product page, the safest wording is that this bevel gear set is publicly linked to multiple Komatsu grader final-drive applications and should always be confirmed by machine model and serial number before order. That is especially important in final-drive parts, where visually similar sets may differ by ratio, shaft form, or differential type.

Weight in KG

Public weight references are close but not perfectly identical. Catalog-style parts sources list 27.592 kg for the part itself, another 3GENEXPORT result shows 29.000 kg, and 3GENEXPORT gives a box weight of 30 kg. The cleanest way to publish this for buyers is to separate bare-part reference weight from shipping weight.

For your website, the best practical wording is:

Reference part weight: 27.592 kg
Typical boxed weight: approximately 30 kg

That presentation is useful because it gives a technically grounded figure for the product itself while still preparing international buyers for realistic shipping calculations.

Why This Part Matters in Real Repairs

The 23B2211100, 23B-22-11100 BEVEL GEAR ASSY KOMATSU matters because final-drive repairs are among the most expensive and alignment-sensitive jobs on a grader driveline. Once the axle or final-drive section is open, the buyer is no longer shopping for a generic spare. They are protecting the tooth pattern, preload, backlash, and long-term stability of the whole drive group. Public sources placing this set in final-drive diagrams make that repair context clear.

In real operating conditions, graders see heavy traction loads, changing ground resistance, long work cycles, and repeated shock from uneven surfaces. A matched bevel set in that environment must remain true under load and maintain a stable mesh pattern. If it does not, the damage spreads fast: bearings run hotter, seals suffer, contact patterns shift, and noise increases. That is why an accurate listing and correct application support matter so much for this type of part. The public sources establish the final-drive role, and the rest follows from standard mechanical behavior of matched ring-and-pinion sets.
