What is 22W1522421, 22W-15-22421 GEAR KOMATSU?

The 22W1522421, 22W-15-22421 GEAR KOMATSU is publicly cataloged as a gear under Komatsu transmission parts. One supplier listing classifies it directly as Komatsu 22W-15-22421 — Gear, and multiple public parts references connect it with grader transmission assemblies rather than engine, hydraulic, or exterior body sections. That classification is important because it helps buyers immediately understand the role of the part: this is a load-bearing drivetrain element used inside a gear-driven motion system, not a general hardware piece.

the part shows a compact cylindrical profile with evenly machined external teeth and a smooth central bore. That visual structure is consistent with a transmission gear designed to deliver stable rotational engagement under repeated operating load. The teeth appear deep and uniform, which is exactly what professional buyers expect when they compare a worn removed part against a replacement listing. The visible geometry supports the catalog classification and reinforces the part’s role in transmission power flow. supported by the public catalog context.

Where 22W1522421, 22W-15-22421 GEAR KOMATSU is used

Public model references show that 22W-15-22421 is associated with Komatsu grader applications in the GD series. Search results and parts references connect the number with GD505A-3, GD505A-3A, and GD511A-1, while an aggregated Komatsu catalog reference also lists GD505A, GD511A, GD521A, and GD525A for this same part number. That makes the safest fitment conclusion this: the part is clearly tied to Komatsu GD-series graders, but final ordering should still be confirmed by model and serial number because transmission parts can vary across production breaks.

Compatible KOMATSU models

Publicly referenced applications

The public sources indicate compatibility or catalog association with the following machines:

• Komatsu GD505A
• Komatsu GD505A-3
• Komatsu GD505A-3A
• Komatsu GD511A
• Komatsu GD511A-1
• Komatsu GD521A
• Komatsu GD525A

These references come from public parts catalogs, manual snippets, and aftermarket parts indexing. Because some listings are family-level and others are serial-number-specific, fitment should be treated as model-and-serial verification required before purchase.

Product function in the transmission system

In grader transmissions, gears like 22W1522421, 22W-15-22421 GEAR KOMATSU are responsible for controlled rotational transfer between connected shafts and clutch-related assemblies. Since public references place this number in the forward and 3rd clutch transmission section, the part should be understood as an important contributor to ratio engagement and torque continuity within the grader’s powertrain. That means buyers are usually replacing it during a targeted rebuild, wear correction, or internal transmission service rather than during routine cosmetic maintenance.

When a transmission gear begins to wear, common consequences can include noisy engagement, poor load distribution, accelerated wear on mating parts, and reduced operating smoothness. Those are engineering inferences based on the function of transmission gears in heavy machinery and on the publicly referenced assembly location of this part number. For workshops, that is why using the correct part number matters so much. A gear that is close in appearance but wrong in tooth profile, width, or bore dimension can create far more costly damage later.

Visual Inspection

the product images of 22W1522421, 22W-15-22421 GEAR KOMATSU show a solid cylindrical transmission gear with a machined central bore and uniformly spaced external gear teeth. The tooth pattern appears straight and robust, indicating a design focused on dependable contact engagement and resistance to repeated rotational stress. The body is compact but dense-looking, which is typical for an internal transmission gear where strength must be concentrated in a relatively small part envelope.

External tooth geometry

The tooth form is the most important visible feature. These evenly spaced teeth are responsible for stable meshing with a corresponding gear in the transmission assembly. Precision in this area affects noise level, wear rate, and torque transfer quality.

Central bore

The internal bore appears smooth and machined for controlled fitment on its shaft or seat location. Proper bore dimension is critical because excessive looseness or interference can compromise the assembly.

Body width

The visible width of the gear suggests it is intended for sustained engagement rather than light intermittent contact. In practical workshop terms, that makes it a serious internal drive component rather than a thin auxiliary gear.

Finish and machining

The surface finish visible in reflects industrial machining quality and a production standard suitable for heavy-duty grader repairs. This matters for buyers who compare photos carefully before placing export orders.

These observations are grounded in and align with the public classification of the part as a Komatsu transmission gear.

Why this gear matters in real operating conditions

A grader spends long hours under changing load, surface resistance, and operator input. Inside that machine, every transmission gear must maintain predictable engagement under stress. The 22W1522421, 22W-15-22421 GEAR KOMATSU matters because the grader’s driveline depends on each internal gear functioning with the correct tooth integrity and dimensional stability. Even a small deviation in wear profile can affect how the surrounding transmission parts behave.

That is why serious buyers do not order parts like 22W1522421, 22W-15-22421 GEAR KOMATSU casually. They usually need the exact number after teardown, inspection, or parts-book confirmation. For that reason, an SEO page should do more than repeat the part name. It should reassure the buyer that the listing is aligned with the correct mechanical category, the right machine family, and the real needs of transmission repair work.

Common reasons to replace 22W1522421, 22W-15-22421 GEAR KOMATSU

Tooth wear over time

Long service cycles can wear the gear teeth, especially if lubrication intervals were missed or if adjacent gears were already damaged.

Transmission rebuilds

This part is often relevant during full or partial transmission overhauls, particularly when the forward and 3rd clutch assembly is being serviced.

Abnormal noise or poor engagement

If a grader transmission begins producing unusual sound or inconsistent drive response, inspection may reveal wear in gears of this class.

Preventive replacement

Experienced workshops may replace internal gears proactively once the transmission is open, reducing the chance of another future teardown.

These are practical workshop scenarios inferred from the part type and assembly context rather than quoted service-manual language.
