23B1511150, 23B-15-11150 HOUSING KOMATSU

The 23B1511150, 23B-15-11150 HOUSING KOMATSU is publicly sold as a Komatsu grader transmission spare part. The clearest seller references place it in Transmission and Torq Parts or Power Train / Housing Parts, and the public sources I could verify most clearly connect this number with GD655 and GD661 grader applications. One Turkish trade listing also describes this part as “piston gövdesi,” which translates to piston body, adding an important clue about its likely function inside the transmission group. 3GENEXPORT lists the weight as 3.14 kg.

From the uploaded images, this part does not look like a simple outer cover or a general frame ring. It has a large machined inner bore, a broad circular body, multiple precision holes around the flange, and several reinforced outer lugs or bosses that suggest controlled mounting and load retention. In practical workshop terms, it looks like a clutch-side or piston-body housing designed to seat, guide, or support transmission components inside a compact oil-fed assembly.

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

Product Overview

The main challenge with a part like this is that the short name “housing” is too generic on its own. In grader transmissions, a housing can be a drum body, piston body, clutch housing, support housing, or another internal carrier-style structure. Public marketplace references help narrow that down. 3GENEXPORT sells the part specifically as 23B-15-11150 Housing Komatsu Grader GD655 in its transmission-and-torque category, while 3GEN ties the same number to GD-661. 3GENEXPORT places the item in Power Train / Housing Parts and publishes the weight at 3.14 kg.

An especially useful clue comes from the Turkish parts-market listing that describes 23B 15 11150 as  piston body. That wording is not the same as an official Komatsu catalog drawing title, so I would not treat it as fully confirmed factory terminology. But it is still valuable because it matches the geometry in your images much better than a loose guess would. A part with this shape is consistent with a piston-body or clutch-body style housing used inside a grader transmission.

There is also a second market-side clue from 3GEN’s broader Komatsu grader parts page, where 23B-15-11150 appears as küçük housing, meaning small housing, among other transmission parts such as cages, pistons, sleeves, gears, hubs, and carriers. That does not give a perfect engineering definition, but it supports the same conclusion: this is not an external body cover or random ring. It is part of an internal transmission assembly.

What This Housing Likely Does

Based on the public category placement and the visible shape in the uploaded images, the most grounded interpretation is that this part functions as an internal transmission housing or piston body in a grader clutch group. The public evidence supports the transmission context, and the “piston body” description supports the idea that this component surrounds, guides, or retains a piston or clutch member rather than acting as a simple passive flange.

In mechanical terms, a housing of this kind usually has several jobs at once. It provides a rigid circular structure. It creates precise seating surfaces for moving parts. It helps keep hydraulic or clutch-related components aligned. It also distributes load through the surrounding bolts and mating parts so the assembly stays concentric under working pressure and repeated shifting cycles. That functional explanation is an engineering inference from the visible design and the public transmission-side classification.

That is why the 23B1511150, 23B-15-11150 HOUSING KOMATSU matters so much during real repairs. A component like this can look deceptively simple on a bench, but if its bore is worn, its flange is distorted, or its mounting surfaces are damaged, the whole surrounding clutch or piston assembly may begin to behave poorly. Problems like uneven engagement, internal leakage, loss of alignment, abnormal heat, or premature wear on cages and related rotating parts can all begin with a housing that no longer holds its geometry correctly.

Visual Analysis of the Uploaded Images

Circular machined body

The part has a large annular form with a precisely machined inner bore. That immediately separates it from flat retaining plates and from lightweight covers. The inner diameter appears intended to locate a rotating or sliding transmission member with controlled clearance.

Multiple bolt and oil-pass holes

Around the circumference, the flange shows many drilled holes in a carefully repeated pattern. Some appear to be for mounting, while others may serve alignment, retention, or fluid-routing roles. This is exactly the sort of layout found on internal transmission housings where accurate assembly order matters.

Reinforced outer lugs

The housing includes several heavier outer sections instead of being a perfectly uniform ring. Those reinforced zones suggest localized clamping or support points. In real service, this usually means the part is meant to carry load and maintain stability under pressure or torque reaction.

Stepped internal seating surfaces

The inner recesses are not simple straight cuts. They appear stepped and layered, which is typical when the housing must accept seals, rings, pistons, or clutch-related hardware in a controlled stack-up.

Substantial material thickness

This is not a thin pressed shell. The visible section thickness suggests a part made to resist distortion. That matters because internal transmission housings must stay dimensionally stable if the machine is going to shift and carry load consistently.

Compatible KOMATSU Models

The public model evidence I could verify most clearly links this number to Komatsu grader applications in GD655 and GD661 families. 3GEN markets it as a Komatsu Grader GD655 transmission part, while 3GENEXPORT and older trade-list pages connect the same number with GD-661.

The safest fitment list to publish from the sources I found is:

• GD655

• GD661

I did not find a strong public factory-style catalog snippet that clearly proved a wider model list for this exact number, so I would not expand the compatibility beyond GD655 and GD661 without a serial-number check. That is especially important for transmission housings, because visually similar parts can belong to different clutch groups, shift stages, or serial-range revisions.

Weight in KG

The clearest published seller weight I found for this part is 3.14 kg from 3GENEXPORT. Their page lists the OEM number as 23B-15-11150, places the part in Power Train / Housing Parts, and gives the weight directly as 3.14 KG.

For a professional product page, the best way to present that is:

Weight: 3.14 kg
Shipping note: confirm final packed weight before dispatch.

That wording gives buyers a usable technical figure while staying realistic about export packing, pallet choice, and final shipping calculations.

Technical Details and Specification Summary

The strongest practical summary for this part comes from combining the public seller evidence with the uploaded images. Publicly, the number is identified as a housing, sold in transmission-and-torque or power-train housing categories, linked most clearly to GD655 and GD661 grader applications, and described by one Turkish trade source as a piston body.

From the visual side, the part can be described as a circular machined transmission housing with a broad flange, multiple drilled mounting holes, reinforced outer bosses, and stepped internal seating surfaces suitable for clutch-side or piston-body service.

Why This Part Matters in Real Repairs

A transmission housing is one of those parts that is easy to underestimate until the machine is already apart. Gears, pistons, cages, hubs, and rings usually get most of the attention, but those parts only work correctly when the housing around them holds alignment, seating depth, and bolt-loaded stability. If the housing is worn or distorted, the rest of the repair can still fail even when the more obvious components are new.

That matters even more on a grader, where transmission parts work under repeated directional change, shifting load, long operating hours, and constant vibration. An internal housing in that environment must stay round, hold its faces true, and keep the internal stack-up in the position the assembly expects. Once the geometry is compromised, small issues can turn into expensive repeat labor.

The visual design of this part supports that seriousness. This is not a decorative shell. It is a load-bearing machined structure. In practical service language, that means buyers should inspect it the same way they would inspect a carrier, a cage, or a clutch hub: by looking at bore condition, face wear, bolt-seat integrity, and surface damage before deciding whether the assembly can be reused.

Buying Guidance Before Ordering

Match both number styles during procurement. Buyers search this part as 23B1511150 and 23B-15-11150, and both appear in public seller references.

Confirm the machine family first. The public evidence I found most clearly supports GD655 and GD661 grader use.

Treat the piston-body interpretation as strong market guidance, not fully proven factory wording. One public listing uses that description, and the image shape supports it, but I did not find a Komatsu diagram snippet that named the subassembly that precisely.

Compare visually before purchase. The machined inner bore, stepped recesses, outer bosses, and hole pattern are all useful checkpoints against the removed workshop part.
