23B1511161, 23B-15-11161 HOUSING KOMATSU

The 23B1511161, 23B-15-11161 HOUSING KOMATSU is publicly listed as a housing assembly for the forward and 3rd transmission section of the Komatsu GD661 grader. Another public seller page lists the same part number simply as a housing, which supports the same OEM identification in the aftermarket.

From the uploaded images, this component is clearly more than a light cover. It has a heavy cast body, a large precision-machined inner bore, reinforced outer sections, and multiple machined seating faces. In practical workshop terms, that design strongly suggests a structural role inside the transmission, where correct alignment and stable support matter as much as the moving parts around it.

At 3GEN Export, we supply this part as an OEM supplier for customers who need dependable sourcing, export-ready service, and worldwide delivery in 5 working days.

Product Overview

The term housing can describe many different parts in heavy machinery. Some housings are simple enclosures. Others are critical structural bodies that help keep internal components correctly positioned under heat, load, and vibration. In this case, the public description is unusually specific: 3genexport identifies this number as a housing assembly for the forward and 3rd section of the Komatsu GD661 grader and places it in the transmission and torque parts category. That gives the 23B1511161, 23B-15-11161 HOUSING KOMATSU a clear drivetrain identity from the beginning.

That context matters to buyers because transmission components are not ordered by shape alone. A part in this section has to do more than fit physically into place. It must also support neighboring elements, preserve bore geometry, and help maintain the dimensional stability of the section during operation. When a machine is already open for overhaul, the housing often becomes one of the quiet decision-makers in the quality of the final repair.

The two number formats are also important for search visibility. Many buyers search the compact style 23B1511161, while others search the catalog style 23B-15-11161. Public product listings connect both formats to the same item, which makes both part-number versions commercially relevant.

What This Part Likely Does

Based on the publicly stated application and the visible construction, this housing is best understood as a fixed structural transmission component. It appears intended to locate and support internal members in the forward and 3rd section while providing a rigid and accurately machined environment for the surrounding assembly. The public listing does not publish a full engineering drawing, but the section description and product category make that interpretation reasonable.

In heavy-duty grader transmissions, parts like this usually help maintain the relationship between moving components and the stationary structure around them. A housing of this type may carry load through bolted joints, preserve alignment between adjoining pieces, and provide the machined surfaces needed for correct seating and controlled fit. That is why this type of part often matters far more than its simple name suggests.

For rebuild work, this becomes especially important. Gears, discs, pistons, seals, and carriers may be the parts that wear most visibly, but those parts depend on the supporting structure around them. If the main support body is worn, distorted, or damaged, the rest of the rebuild may never feel fully correct in service.

Visual Features Seen in the Uploaded Images

Deep machined bore

The most obvious feature is the large inner bore. It is smooth, wide, and clearly finished to a controlled surface. That indicates a functional fit area rather than a rough pass-through opening.

Reinforced cast body

The outer form shows meaningful thickness and mass. This is consistent with a part designed to resist flex under working load rather than a simple thin-wall enclosure.

Raised mounting sections

Several raised outer sections appear around the circumference. These likely provide added structural support and controlled mounting geometry where adjoining pieces connect.

Mixed cast and machined surfaces

The contrast between the cast body and the machined internal and upper faces follows classic heavy-machinery design practice: strength where mass is needed, accuracy where fit matters most.

Purpose-built transmission construction

Nothing in the part’s shape appears decorative. The visible geometry is all business. Every shoulder, face, bore, and fastening area appears to serve support, alignment, or mounting purposes.

Why the Housing Role Matters

In any transmission, moving parts can only perform properly when the stationary parts around them remain dimensionally correct. That is one of the easiest ways to understand the value of the 23B1511161, 23B-15-11161 HOUSING KOMATSU. Even when the wear parts are replaced, a damaged or out-of-true housing can still affect fit, contact pattern, and overall service life.

This is even more relevant in grader duty. A Komatsu grader transmission operates under long work cycles, repeated load changes, vibration, and heat. A structural transmission body has to absorb those conditions without losing its alignment function. In workshop terms, that means the quality of the support structure often defines whether the repair will last or return for a second intervention.

Publicly Referenced KOMATSU Models

The clearest public model reference for this OEM number is GD661. The 3genexport product page directly identifies the item as a housing assembly for the forward and 3rd section of the Komatsu grader GD661.

A separate public procurement record shows the same part number requested for GD655A-5. That does not replace serial-number confirmation, but it is still useful because it shows real market-side use of the same OEM number in connection with that model family.

So the strongest public application references for the 23B1511161, 23B-15-11161 HOUSING KOMATSU are:

GD661

GD655A-5 procurement-side reference

For professional ordering, final fitment should still be checked by machine serial number before purchase.

Technical Description

The 23B1511161, 23B-15-11161 HOUSING KOMATSU is best described as a transmission housing assembly used in the forward and 3rd section of a Komatsu grader drivetrain. Publicly accessible parts pages place it in the transmission and torque parts group and identify GD661 as the clearest model reference.

Commercially, the most useful description is not the longest one but the clearest one. This part is a structural transmission housing. It is associated with the forward and 3rd section. It is publicly listed under both 23B1511161 and 23B-15-11161. It is sold in the Komatsu grader transmission parts space rather than in general hardware or external body categories.

That makes it highly relevant to buyers searching by OEM number, model-based transmission repair, or grader driveline overhaul.

Installation and Inspection Considerations

When sourcing a transmission housing, the buyer should verify more than the general name. The most important checks are the OEM number, the machine model, the transmission section involved, and the machine serial range if available. This is particularly important with internal drivetrain parts, because neighboring components can look similar while belonging to different positions or revisions.

The uploaded images help a lot with practical comparison. A technician can compare the depth of the body, the size and finish of the bore, the placement of the reinforced sections, and the general fastening layout against the removed part on the bench. That kind of visual confirmation is often what prevents costly ordering errors.

For inspection, the main attention points should be the condition of the bore, the machined seating lands, the mounting faces, and any signs of impact damage or distortion. Those are the areas most likely to affect how the rebuilt section performs once the grader returns to work.

Weight in KG

I could verify public application information for this part number, but I could not verify a reliable published net weight for the 23B1511161, 23B-15-11161 HOUSING KOMATSU from the sources available online. The pages I found confirm the part identity and transmission context, but they do not publish a trustworthy exact kilogram value.

So the most accurate commercial wording is:

Weight in KG: exact net weight not publicly verified online
Packed weight: confirm before shipment

That is the safest way to avoid quoting an unsupported figure.
