23A-70-15180 Plate Komatsu

The 23A-70-15180 Plate Komatsu is a catalog-matched Komatsu drive-system component used in motor grader applications, and parts references place it inside the circle reverse gear area of the machine. Online listings also place this part in the drive group / chain power transmission category, which already tells buyers that it is not a cosmetic cover or a generic washer-style plate, but a functional part inside a load-bearing assembly.

From the uploaded images, the 23A7015180 Plate Komatsu has the visual form of a thick circular precision plate with a central bore and two smaller mounting or locating holes spaced opposite one another. That geometry is important. It suggests a part designed to sit flat, register accurately, and maintain controlled alignment inside a Komatsu transmission or circle reverse gear housing rather than a free-form bracket or rough spacer. In working equipment, a part with this shape is typically expected to help stabilize part-to-part positioning, support assembly accuracy, and preserve consistent internal clearances during operation.

Because this is a plate used in a grader drive-related system, the value of the 23A-70-15180 Plate Komatsu is not about visual complexity. Its importance is in dimensional correctness. A part like this has to match the bore size, thickness, face flatness, and hole placement of the original assembly drawing so that the adjacent bushings, housing surfaces, dowels, seals, and rotating parts stay correctly positioned. That is why buyers searching for 23A7015180 Plate Komatsu are usually not browsing casually. They are solving a mechanical fit problem, preventing assembly delay, or replacing a worn internal item during transmission or circle reverse gear service.

What the 23A7015180 Plate Komatsu Does

In practical workshop terms, the 23A-70-15180 Plate Komatsu works as a locating and supporting plate within the circle reverse gear assembly. Catalog context shows it grouped alongside a housing, bushings, oil seals, dowel pins, shims, and related reverse-gear components, which strongly indicates that the part helps define how surrounding pieces sit relative to one another in the assembly.

That matters because Komatsu grader systems rely on controlled movement rather than loose tolerance. When one internal plate wears, distorts, or no longer seats properly, the result can be more than simple replacement inconvenience. It can affect how the housing closes, how mating components align, how oil-sealed sections remain supported, and how the assembly responds under repeated directional and working loads. The 23A7015180 Plate Komatsu therefore supports more than one static point. It contributes to the overall dimensional discipline of the reverse-gear area.

For fleet managers, this is exactly why a part that looks simple on the bench can be critical on the machine. Once installed inside a drive-related assembly, the 23A-70-15180 Plate Komatsu becomes part of the structure that keeps the entire unit properly stacked, seated, and mechanically consistent. That makes it a small part with a large effect on service quality.

Where the 23A-70-15180 Plate Komatsu Fits

Searchable parts-book references connect the 23A7015180 Plate Komatsu to Komatsu motor grader circle reverse gear assemblies. One catalog snippet identifies it directly under “CIRCLE REVERSE GEAR,” and another places it together with 23A-70-15150 bushing, 23A-70-15160 bushing, 23A-70-15210 housing, an O-ring, shims, and dowel pins. That surrounding catalog context is valuable because it helps buyers understand that the 23A-70-15180 Plate Komatsu belongs inside a controlled internal assembly rather than a random external mounting point.

This also explains why correct part-number matching matters. In Komatsu grader assemblies, a plate that is close in appearance but wrong in thickness, bore finish, or dowel-hole location can create avoidable installation problems. The 23A7015180 Plate Komatsu must match the intended catalog position so the surrounding housing and internal rotating or supported parts can be assembled without forcing, rework, or guesswork.

Compatible Komatsu Models for 23A7015180 Plate Komatsu

Online catalog references associate the 23A-70-15180 Plate Komatsu with multiple Komatsu motor grader models. Search results and parts-book references report compatibility with the following model families, depending on serial range and catalog break:

GD305A-1A
GD405A-2
GD510R-1
GD511A-1
GD521A-1
GD521A-1E
GD525A-1C
GD605A-5S
GD611A-1
GD621A-1
GD661

Some sources also provide serial-specific examples, including GD305A-1A S/N 6734-UP, GD510R-1 S/N 15001-UP, GD511A-1 S/N 10001-UP, GD405A-2 S/N 1001-UP, GD611A-1 S/N 10001-UP, and GD605A-5S S/N 4001-UP. Because Komatsu fitment can vary by serial break, the safest purchasing method is always to confirm the exact part number on your existing catalog, machine plate, or service record before ordering.

Visual and Technical Characteristics

The uploaded images show a flat round plate with a machined center opening, a uniform outer diameter, and two auxiliary holes that appear intended for fixing, doweling, or controlled placement. The finish looks like a precision-machined industrial surface rather than an unfinished casting, and the overall profile suggests a component designed for face-to-face seating against a mating part. That is exactly the kind of shape buyers expect when they search for 23A-70-15180 Plate Komatsu for grader transmission-related service.

Several details matter here. First, the central bore must be dimensionally correct because it governs how the plate centers around or clears the adjoining feature. Second, the outer face must sit evenly because any rocking or uneven seating can compromise the entire subassembly. Third, the secondary holes must be positioned accurately because dowel or fastener mismatch turns a straightforward repair into an installation problem. In other words, the usefulness of the 23A7015180 Plate Komatsu is in its machining discipline, not just in its outline.

Why a Correct Plate Matters in Grader Service

Motor graders work in long cycles, under vibration, shock, and repeated directional correction. Even though the 23A-70-15180 Plate Komatsu is not itself a large rotating mass, it belongs to a section of the machine where internal relationship between parts matters. A correct plate helps preserve how the housing, bushings, shims, seals, and neighboring components sit together. When technicians rebuild or refresh the circle reverse gear area, using the correct 23A7015180 Plate Komatsu can help restore intended assembly geometry rather than simply filling space.

This is especially important in fleets where machines are expected to return to work quickly. A part that fits immediately reduces downtime, prevents repeated trial fitting, and supports a more predictable rebuild process. That is why many professional buyers look for the exact code 23A-70-15180 Plate Komatsu instead of shopping by appearance alone.

Installation and Service Considerations

When installing the 23A7015180 Plate Komatsu, technicians typically focus on five practical checks. The first is face condition. The mating surface should be clean and free from burrs, old sealant residue, or impact marks. The second is hole alignment. The two smaller holes should line up naturally rather than requiring force. The third is bore fit. The center opening should register correctly with the adjoining feature without drag from distortion. The fourth is thickness consistency. The plate should sit evenly and support proper stack-up with related bushings, shims, or housing parts. The fifth is surrounding component condition. If the plate is being replaced because of wear, the housing, bushings, dowels, and seals around it should also be checked.

In real service environments, technicians often discover that a plate has been affected by more than simple age. Poor lubrication conditions, long-term vibration, improper tightening sequence, or damage elsewhere in the assembly can all leave marks on a precision part. Replacing only one item without inspecting the surrounding reverse gear components may solve the immediate fit issue but leave the underlying cause untouched. That is another reason the 23A-70-15180 Plate Komatsu should be viewed as part of an assembly solution, not just a single loose spare.
