6131115230, 6131-11-5230 JOINT KOMATSU

When buyers search for 6131115230, 6131-11-5230 JOINT KOMATSU, they are usually looking for an exhaust-side connection part used in Komatsu engine and machine applications built around the 6D105 / S4D105 / S6D105 family, not a generic pipe sleeve. Public parts references identify 6131-11-5230 as JOINT, place it in muffler and mounting or related exhaust groups, and connect it with applications including S6D105-1MM-B S/N 80070-UP, S6D105-1JJ S/N 79301-UP, S6D105-1NN S/N 81519-UP, JV100WA-1, and broader compatibility tags such as 6D105, JV100WA, JV100WP, S4D105, and S6D105. Public seller references also show a gross weight around 0.67–0.68 kg.

From the uploaded images, 6131115230, 6131-11-5230 JOINT KOMATSU has the shape of a machined exhaust connection flange rather than a simple ring. It features a broad two-bolt mounting face, a cylindrical inner passage, and an outer sealing shoulder or groove, all of which are consistent with a part designed to join exhaust components while maintaining alignment and seal integrity. Based on the public catalog placement in muffler-and-mounting diagrams and the visible geometry in the photos, the most reasonable interpretation is that this part functions as a muffler / exhaust connection joint or intermediate flange in the Komatsu exhaust system. That functional description is an inference, but it is strongly supported by the surrounding catalog context.

For an e-commerce page, that distinction matters. A buyer searching 6131115230 is usually not doing broad research. They are trying to match a known exhaust connection part in a Komatsu engine or machine already in service. That means the page should explain the exhaust application clearly, show the main public model references, and confirm that 3GEN Export supplies the part as an OEM supplier with worldwide delivery in 5 working days.

Product Overview

6131115230, 6131-11-5230 JOINT KOMATSU is best understood as a machine-specific exhaust connection joint used in Komatsu muffler and mounting assemblies. Public parts-manual references repeatedly place this number in the same group as the muffler, bracket, bolts, spacers, seal ring, drain pipe, hose, clip, and exhaust pipe. In the S6D105-1MM-B parts list, the number appears as item 9, directly followed by 6131-11-5360 BOLT and 6114-11-5280 RING,SEAL, which is exactly the kind of parts neighborhood expected for a flanged exhaust joint that must bolt in place and seal against the adjoining component.

The same pattern appears in the GD505A-3 public parts-manual snippet. There, 6131-11-5230 JOINT is listed in the muffler and mounting group for S6D105-1JJ S/N 79301-UP, together with a seal ring, mounting bolts, drain pipe, hose, and exhaust pipe. That repeated arrangement across different Komatsu applications is important because it shows that 6131115230, 6131-11-5230 JOINT KOMATSU is not an isolated one-off component. It is a reusable design within the Komatsu exhaust system architecture for several 105-series engine installations.

The images also support that conclusion. The part is not a loose gasket or thin spacer. It is a solid machined body with a two-hole flange and a deep cylindrical section that appears designed to seat, align, and support the joint between adjoining exhaust parts. In commercial terms, that makes 6131115230, 6131-11-5230 JOINT KOMATSU a fit-sensitive exhaust hardware part rather than a commodity consumable. Workshops and dealers therefore benefit from sourcing it by exact number instead of relying on dimensions alone.

What 6131115230, 6131-11-5230 JOINT KOMATSU Does

The practical job of 6131115230, 6131-11-5230 JOINT KOMATSU is to provide a secure, aligned, and sealed transition between connected exhaust-system components. Public parts references do not spell out the engineering function in narrative form, but their assembly context makes the use case clear. This joint is positioned in the muffler and mounting group, and it is paired with a seal ring and mounting bolts. That strongly indicates it works as the connection interface between the muffler-side assembly and the adjoining exhaust section.

In real equipment use, that role matters because exhaust connections must do more than just pass gas from one part to another. They also need to preserve alignment, keep leakage under control, and tolerate heat, vibration, and engine movement. A poorly matched or worn connection part can lead to exhaust leakage, unstable pipe positioning, gasket or seal failure, and stress on nearby brackets or pipes. That is one reason buyers search 6131115230, 6131-11-5230 JOINT KOMATSU by exact number: they need the correct flange-style connection, not just a similar-looking ring.

Because the public parts references show this number across multiple engine and machine applications, it is also fair to say that this joint design serves as a standardized exhaust connection solution within part of the Komatsu 105-series platform. The number is publicly associated with 6D105, S4D105, S6D105, and machine-linked applications such as GD505A-3, GD661A-1, and JV100WA-1. That cross-application reuse is common in industrial engine platforms, where the same exhaust interface part is carried into different machine installations with similar engine architecture.

Visual and Engineering Features

Two-bolt flange layout

One of the clearest visible features of 6131115230, 6131-11-5230 JOINT KOMATSU is the flat two-bolt flange. This is a classic heavy-equipment connection format because it helps maintain stable alignment while allowing the joint to be removed during service. In exhaust applications, a flange like this helps distribute clamping force more evenly than a thin ring or clamp-only connection. The public parts pages support that reading because the joint is repeatedly listed together with dedicated bolts and washers in muffler-and-mounting sections.

Machined inner bore

The inner passage is smoothly machined and cylindrical. That matters because exhaust flow parts need a controlled internal path, especially where they connect to adjoining pipe or muffler components. The consistent bore also supports correct fit and centering when the part is installed. From a service standpoint, the machined bore helps distinguish this item from a pressed sheet-metal adapter or simple spacer.

Sealing shoulder / ring seat

The outer cylindrical section appears to include a shoulder or groove area where a seal ring seats. That matches the public parts references showing 6114-11-5280 RING,SEAL or 6136-12-5280 RING,SEAL positioned right next to the joint in the same assembly. This is one of the strongest reasons to describe 6131115230, 6131-11-5230 JOINT KOMATSU as a sealing and connection component rather than only a mounting flange.

Rigid machined body

The part’s body looks heavy and rigid relative to its size, which is exactly what is needed in an exhaust connection that must tolerate vibration and heat cycles over time. A rigid machined joint helps preserve flange flatness, keep the seal ring seated correctly, and reduce misalignment between the connected exhaust parts. For workshops, this is a practical quality point because exhaust leaks often begin at stressed or poorly supported interfaces.

Technical Context and Specification Clues

Public references consistently identify the part name simply as JOINT, but the assembly context tells more of the story. In the S6D105-1MM-B parts list, the joint appears in MUFFLER AND MOUNTING rather than in lubrication, cooling, or intake sections. In GD505A-3 public references, it appears in MUFFLER AND MOUNTING(#79301-92777) and MUFFLER AND MOUNTING(#92778-) for the relevant engine installation. That repeated placement strongly supports the exhaust-joint interpretation.

Weight references are also relatively consistent. A public B2B parts listing shows 0.67 kg, while another public marketplace-style listing shows 0.680 kg for 6131-11-5230 JOINT. Those are gross or listing weights rather than engineering mass values, but they are still useful for quoting, packing, and logistics planning. The close agreement between the two public sources makes about 0.67–0.68 kg a practical reference weight for e-commerce use.

Another useful technical clue is the number of companion parts listed around the joint. The public engine and grader parts references consistently place it with a seal ring, mounting bolts, spacers, muffler, bracket, drain pipe, hose, and exhaust pipe. That is important because it confirms that the joint is not a standalone exhaust ornament or cosmetic flange. It is part of a working sealed connection within the mounted exhaust assembly.

Compatible KOMATSU Models and Engine Families

Public compatibility data around 6131115230, 6131-11-5230 JOINT KOMATSU is spread across engine, machine, and application pages. The broadest public catalog snippets associate the part with 6D105, S4D105, S6D105, JV100WA, and JV100WP applications. That is useful because it shows the part belongs to a wider Komatsu 105-series ecosystem rather than to only one machine.

The more specific public machine-linked references include the following:

Engine-linked and machine-linked public examples

S6D105-1MM-B S/N 80070-UP in MUFFLER AND MOUNTING, where the joint is listed with seal ring, bolts, drain pipe, and exhaust pipe.

Public seller references also mention applications tied to GD355A-1, GD405A-1, GD510R, and related 105-series installations. Because these applications are serial-sensitive and sometimes engine-coded rather than machine-coded, the safest commercial wording is this: 6131115230, 6131-11-5230 JOINT KOMATSU is publicly linked to multiple Komatsu 105-series engine installations and selected machine applications, but final fitment should always be checked by exact machine model, engine code, and serial number before order confirmation.

Why This Part Matters in Maintenance

Exhaust connection parts often get less attention than mufflers or manifolds, but they are critical to system reliability. If the joint no longer holds the connected parts squarely, the seal ring may not seat correctly. If the flange face is stressed or damaged, leakage may develop. If the connection is loose or misaligned, the surrounding pipe, bracket, or hose may be subjected to unnecessary vibration and load. That is why 6131115230, 6131-11-5230 JOINT KOMATSU matters in real maintenance even though it is smaller than the muffler or exhaust pipe itself.

For workshops, this part is especially important during exhaust repairs, engine overhauls, muffler replacement, or whenever the mounted exhaust system is being rebuilt. In those cases, replacing a worn joint can help restore proper sealing and alignment instead of reusing a connection piece that may already be heat-cycled, distorted, or worn at the seal seat. Because the public parts references consistently pair the joint with a ring seal, it is also practical to inspect or replace the sealing element at the same time.
