23A1512280, 23A-15-12280 HUB GEAR KOMATSU

Heavy-Duty Transmission Hub Gear for Komatsu Motor Grader Applications

The 23A1512280, 23A-15-12280 HUB GEAR KOMATSU is a Komatsu motor grader transmission and torque component publicly listed as HUB GEAR. Public seller listings consistently connect this exact part number with Komatsu grader GD511, and one broader Komatsu grader spare-parts list also describes 23A-15-12280 as a GD505 transmission hub gear in Turkish. Taken together, the public evidence strongly supports positioning this part as a grader transmission hub gear used in the GD511 / GD505 family context, though exact fitment should still be confirmed by serial number and parts book before sale.

For buyers searching by OEM number, this is not a generic round gear. The images show a large, precision-machined hub gear with an internally splined center bore, an integrated gear ring, and a thick mounting body, which is consistent with a heavy-duty transmission or torque-transfer part. The visual description comes from the images you provided, while the public sources place the part in Transmission and Torq Parts for Komatsu graders.

At 3GEN Export, we present 23A1512280, 23A-15-12280 HUB GEAR KOMATSU as an OEM supplier solution for professional buyers who need exact-number grader transmission parts. We deliver all over the world in 5 working days, helping workshops, resellers, contractors, and fleet managers reduce downtime when drivetrain and transmission components need urgent replacement.

What Is 23A1512280, 23A-15-12280 HUB GEAR KOMATSU?

The clearest public identification available online is simple: 23A-15-12280 HUB GEAR KOMATSU GRADER GD511. Multiple 3GEN category and tag pages repeat that exact naming, and the same public seller environment places the part inside Transmission and Torq Parts. That gives us the strongest reliable baseline for the product page: this is a Komatsu grader transmission-side hub gear, not a hydraulic, cab, or undercarriage part.

A broader Komatsu grader parts list from the same seller environment adds more context. That page describes 23A-15-12280 as GD.505 şanzuman hub dişli, which translates to GD505 transmission hub gear. Because this source is a broad commercial list rather than a factory catalog page, the safest interpretation is that the part is commercially associated with Komatsu grader transmission applications around GD505 / GD511 families, but final fitment must be checked carefully.

That is exactly why part-number SEO matters here. Buyers looking for 23A1512280 or 23A-15-12280 are usually trying to match a specific transmission component from an existing gearbox or parts list. A strong product page should support both part-number formats and also include related search phrases like Komatsu grader hub gear, Komatsu transmission hub gear, and GD511 hub gear Komatsu without repeating the exact keyword too aggressively.

Why This Hub Gear Matters in Real Grader Operation

A hub gear in a grader transmission system is a precision component, not a cosmetic part. Public seller sources place 23A-15-12280 in the Transmission and Torq Parts group, which means it belongs in a system responsible for controlled power transfer inside the grader drivetrain. From a mechanical standpoint, a part with internal splines and an external gear ring like the one shown in your images would typically serve as a torque-transfer interface between shafts, carriers, or related transmission components. That functional explanation is an inference from the part’s geometry and category, but it is consistent with the public classification.

When a transmission hub gear wears, chips, cracks, or develops spline damage, the effects can spread quickly across the assembly. Poor engagement, backlash, noise, vibration, and uneven load transfer can all become more likely. Even if only one gear component is visibly damaged, professional workshops often inspect the mating shaft, bearings, carriers, and surrounding gears at the same time. That is not stated word-for-word in the public listings, but it is standard transmission-service logic for a part of this type.

For machine owners, that makes 23A1512280, 23A-15-12280 HUB GEAR KOMATSU an important replacement item. It helps maintain reliable torque transfer, stable gear engagement, and the overall service condition of the transmission assembly. On a motor grader, where smooth and dependable driveline behavior matters for long grading passes and controlled work under load, that reliability is critical.

Technical Details of 23A1512280, 23A-15-12280 HUB GEAR KOMATSU

Part Number Formats

This part should be listed in both primary searchable formats:

23A1512280
23A-15-12280

Including both formats is important because buyers may search from invoices, gearbox parts lists, warehouse labels, or online catalogs that use different styles.

Product Name

The strongest public product naming is:

HUB GEAR
HUB GEAR KOMATSU GRADER GD511

Product Category

The clearest public category is:

Transmission and Torq Parts

Machine Type

Public sources identify the part in a Komatsu grader context, especially GD511, with additional commercial reference to GD505 transmission hub gear.

Visual / Structural Features Visible in the Product Images

From the images you uploaded, the part clearly appears to have:

• an integrated external gear ring
• a splined internal bore
• a thick hub body
• a multi-hole machined face
• a heavy-duty cylindrical center section

These are image-based observations, not public catalog specs. They are useful because they support describing the item as a transmission hub gear rather than a plain spur gear or simple flange.

Weight in KG

I could not verify a trustworthy public KG weight for 23A1512280, 23A-15-12280 HUB GEAR KOMATSU from the accessible search results. The sources I found confirm the part number, product name, category, and grader association, but they do not expose a reliable physical weight figure. Because of that, the safest product-page wording is:

Weight: please confirm before shipment

I do not want to invent a number where the public evidence is insufficient.

Compatible KOMATSU Models for 23A1512280, 23A-15-12280 HUB GEAR KOMATSU

This is the most careful way to present fitment from the public evidence.

Strongest Publicly Referenced Model

GD511 , multiple public seller pages explicitly list 23A-15-12280 HUB GEAR KOMATSU GRADER GD511.

Additional Commercial Reference

GD505 , a broader Komatsu grader spare-parts list describes 23A-15-12280 as GD505 transmission hub gear. Because this comes from a commercial list page rather than a detailed factory diagram, it should be treated as supporting market reference rather than definitive universal fitment.

Safest Customer-Facing Fitment Statement

• Komatsu Grader GD511
• Commercially referenced for GD505 transmission applications
• Final fitment must be confirmed by exact part number, machine model, and serial number

That wording protects accuracy and still helps the page rank for realistic buyer searches.

Product Design and Working Characteristics

The 23A1512280, 23A-15-12280 HUB GEAR KOMATSU stands out visually because it combines two critical functional features in one body: a toothed outer gear section and a splined inner hub. That combination usually means the part is designed to both receive torque internally and transmit it externally through gear engagement. This is a mechanical inference from the shape visible in the images, but it fits perfectly with the public classification as a transmission and torque part.

The machining visible on the face and bore suggests the part is made for close-tolerance installation. Transmission parts of this type are typically not forgiving of poor dimensional matching. That is why exact part-number sourcing is so important. A visually similar hub gear may still be wrong if its spline count, pitch, bore, or face dimensions differ slightly.

For workshops, that means the part should be treated as a precision replacement item. For resellers, it means that part-number SEO and exact-number listing are much more valuable than broad keyword stuffing. For contractors, it means the right replacement can help reduce avoidable downtime in grader transmission repairs.

Key Benefits of 23A1512280, 23A-15-12280 HUB GEAR KOMATSU

Supports Transmission Torque Transfer

Because the part is publicly sold under Transmission and Torq Parts, it should be positioned as a working transmission component rather than a cosmetic or structural accessory.

Built for Komatsu Grader Applications

Public listings tie the part directly to Komatsu grader contexts, especially GD511.

Useful for Gearbox Rebuild and Repair

A hub gear of this type is especially relevant for professional workshops handling transmission overhaul, worn gear replacement, or driveline restoration. This is a practical inference from the component type and public category.

Fits 3GEN Export’s OEM Supplier Positioning

This part is exactly the kind of model-specific heavy machinery component that suits a specialist aftermarket and OEM supplier marketplace.

Common Reasons for Replacement

The public sources do not list failure modes for this exact part, but for a hub gear in a grader transmission, the most realistic replacement reasons are:

• gear tooth wear
• chipped or broken teeth
• spline wear
• looseness in the transmission assembly
• rebuild work during gearbox overhaul
