23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU

The 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU is a hydraulic transmission pump assembly used in Komatsu motor graders. Public catalog and seller references identify this part number as a pump assembly for the transmission circuit, and current listings repeatedly connect it with grader applications such as GD505A, GD511A, GD521A, GD605A, GD611A, GD621A, GD621R, GD623A, GD625A, and GD661A. Public sources also place its reference weight at about 6.8 kg.

From the uploaded images, the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU has the visual form of a compact gear-style hydraulic pump built for heavy-duty grader service. The yellow body, splined input shaft, machined front mounting face, and side port layout all point to a component designed for stable oil flow, controlled pressure delivery, and secure installation in a transmission-related hydraulic system.

For workshops, fleet managers, and spare-parts buyers, this is not a casual replacement item. A pump in the transmission circuit is one of those parts that directly affects machine response, lubrication quality, and drive-system reliability. When it wears, loses efficiency, or is damaged, the machine can begin showing pressure-related performance problems long before the operator sees a complete failure. That is why the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU deserves a detailed and technically clear product page.

At 3GEN Export, we supply this part as an OEM supplier and deliver worldwide in 5 working days for buyers who need dependable sourcing and fast global support.

Product Overview

The 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU appears online under both the hyphenated and non-hyphenated number styles. That matters for real-world procurement because different buyers search in different ways. Some use 23A-60-11200 from older parts catalogs, while others search 23A6011200 from ERP systems, invoices, or supplier databases. Public listings consistently connect both formats to the same Komatsu grader pump assembly.

Public catalog snippets describe the unit as a hydraulic pump for transmission use, while model-fitment listings describe it as a transmission pump or hydraulic gear pump for graders. Taken together, those sources support a clear commercial description: the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU is a grader transmission pump assembly designed to circulate and pressurize oil within the transmission system.

That function is important because a motor grader depends on consistent hydraulic and transmission oil flow for smooth power delivery and stable operation. When a pump in this circuit starts to lose performance, the result can spread across the machine through weaker pressure control, reduced lubrication stability, and increased stress on related transmission components. This is a practical inference from its catalog placement as a transmission hydraulic pump and from the role such pumps play in grader driveline systems.

What the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU Does

The most reliable way to understand the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU is to start with how public sources classify it. A 777parts catalog result labels it as a hydraulic pump for transmission use, and compatible-model listings repeatedly tie it to Komatsu motor graders rather than to excavators, loaders, or dozers. That tells buyers this is a grader-specific transmission-side hydraulic unit rather than a generic pump with broad unrelated fitment.

In practical operating terms, the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU is there to keep transmission oil moving where it needs to go. A component of this kind supports oil circulation, pressure generation, and lubrication continuity inside the transmission system. Even when seller terminology varies between “transmission pump,” “hydraulic pump,” and “gear pump,” the intended role remains consistent: controlled movement of transmission oil under working conditions.

That is why this part matters so much in field service. A grader may still move with a weak pump for a while, but performance quality can begin to degrade before a full breakdown happens. Pressure inconsistency, rising internal heat, unstable lubrication, and harsher wear on surrounding parts are exactly the kinds of downstream problems buyers try to prevent by replacing a transmission pump assembly before it becomes a larger repair event. That interpretation follows directly from the pump’s transmission function and from standard hydraulic-system failure behavior.

Visual Analysis of the Uploaded Images

The uploaded images make the design of the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU much easier to explain.

Splined input shaft

The front drive end features a splined shaft, which is one of the clearest visual indicators that this pump is driven mechanically by a mating component. Splines are used when torque transfer must be positive, repeatable, and resistant to slippage. On a pump assembly, that usually means the pump is expected to engage directly with the machine’s drive arrangement rather than through a loose or friction-based connection.

Machined front mounting face

The front face is fully machined and includes mounting-hole geometry around the shaft area. This points to a secure bolt-on installation into a transmission or hydraulic mounting position. A pump working in a grader transmission circuit cannot afford mounting movement or misalignment, so the robust front face is exactly what buyers expect to see.

Side port configuration

The side opening with threaded fastener points suggests a controlled port connection for fluid flow. Even without over-claiming an exact inlet-versus-outlet orientation from the photo alone, the visible geometry clearly shows the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU is built for sealed oil routing through a defined connection surface.

Compact heavy-duty housing

The main housing has a short, dense, industrial shape. That matters because a transmission pump for a grader has to survive vibration, temperature variation, and long work cycles while remaining compact enough to fit within the machine’s driveline packaging constraints. The visual balance of the housing, shaft, and mounting surfaces strongly supports its role as a grader-duty hydraulic pump.

Compatible KOMATSU Models

Publicly available seller and catalog references connect the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU with a broad group of Komatsu motor grader models.

The strongest recurring model family references include:

• Komatsu GD505A

• GD625A-1 S/N 60001-UP for North America

• GD661A-1 S/N 10001-UP.

For product-page accuracy, the safest wording is that the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU is used in multiple Komatsu grader applications and should always be checked against the exact machine model and serial number before order. That final serial confirmation matters because grader transmission and hydraulic parts often change across production ranges even when the machine family name stays the same.

Weight and Technical Details

One of the more useful details buyers want immediately is weight. Public catalog and seller sources agree closely on this point, listing the 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU at 6.8 kg or 6.800 kg. That makes 6.8 kg the strongest current reference weight for quoting, shipping, and packing calculations.

They need a page that quickly confirms the part type, application family, and physical logic of the unit. A product page that does that well reduces hesitation and improves conversion quality.

Why This Pump Matters in Real Repairs

The 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU matters because transmission health is never just about gears and clutches. The oil circuit behind the system is what keeps those components working under stable conditions. A failing pump can undermine pressure delivery and lubrication quality long before a complete mechanical failure appears. Seller descriptions of this part repeatedly emphasize its transmission use and its role in maintaining oil circulation and hydraulic performance, which is why it is treated as a high-value service component rather than a minor accessory.

In grader work, that matters even more. Motor graders spend long periods under variable load, surface resistance, and directional adjustment. If oil supply becomes weak or inconsistent inside the transmission circuit, the machine may begin to show reduced smoothness, added internal wear, and more heat stress across the driveline. That is why transmission pump replacement is often approached as preventive protection for the whole system, not just as a one-part repair. This is an inference grounded in the part’s documented transmission-pump role.

The 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU is therefore especially important for fleet operators and rebuild shops. When a grader is down, the cost is not only the part itself. It is the lost machine availability, the delayed work schedule, and the labor hours tied up in the repair window. A correct pump assembly helps protect all three.

A strong heavy-equipment product page should help the buyer avoid mistakes before they happen.

Match both number formats

The 23A6011200, 23A-60-11200 TRANSMISSION PUMP ASSY KOMATSU should always be searchable in both styles. Some buyers search with hyphens, some without, and some by mixing spaces from printed parts documents. Including all common variants naturally on the page improves search reach and helps procurement teams find the right listing faster.

Confirm the grader model

Public sources tie the part to GD505A, GD511A, GD521A, GD605A, GD611A, GD621A, GD621R, GD623A, GD625A, and GD661A families. That gives the buyer a strong starting point, but it should not replace serial verification.

Confirm the serial range

Where serial-specific data is available, use it. Public listings show that this part number is associated with particular ranges such as GD511A-1 S/N 10001-UP, GD623A-1 S/N 30001-UP, and GD625A-1 S/N 60001-UP for North America. That is exactly the kind of detail that prevents wrong orders.
