1545071180 / 154-50-71180 FLANGE KOMATSU

The 1545071180 / 154-50-71180 FLANGE KOMATSU is a heavy-duty round mounting part used in the equalizer bar and pivot shaft area of selected Komatsu bulldozers. Online parts sellers market this number as a flange for D85EX-15 applications, while catalog references also place the same number inside the pivot shaft and equalizer bar group and classify it under washer-style terminology. In practical e-commerce terms, that means buyers search this item in more than one way, so a strong product page should support both the commercial name and the catalog number format.

From the images you provided, this component has a thick circular body, a raised center hub on one side, a recessed face on the other side, and eight evenly spaced bolt holes. That shape strongly suggests a structural mounting and load-distribution role inside a high-load assembly rather than a light auxiliary function. For fleet owners, workshops, resellers, and contractors, this is the type of part that matters because fit, alignment, and machining accuracy directly affect long-term service performance.

At 3GEN Export, we supply this part as an OEM supplier for customers who need dependable industrial spare parts with fast export handling. We deliver worldwide in 5 working days, helping reduce downtime for Komatsu dozers working in construction, quarry, mining, roadbuilding, landfill, and earthmoving operations.

Product Overview

The 1545071180 / 154-50-71180 FLANGE KOMATSU is associated with the D85 platform and is tied to the equalizer bar, bogie, and pivot shaft section in seller listings. 3GENEXPORT identifies it specifically as “154-50-71180 FLANGE KOMATSU DOZER D85EX15” and places it in the equalizer bar, bogie, and pivot shaft category. Other catalog-style sources list the same number in pivot shaft and equalizer bar diagrams, which confirms that this is not a cosmetic part but a mechanically important component in the machine frame-related assembly.

That matters for two reasons. First, the part must fit correctly into a stressed structural zone. Second, buyers may search for it by different names depending on whether they come from workshop practice, catalog research, or purchasing history. Some users type only the full number 1545071180. Others search 154-50-71180. Others search by machine model and function, such as D85EX-15 flange or pivot shaft flange. A properly optimized page should satisfy all of those search patterns without sounding repetitive or unnatural.

What the Images Reveal About the Part

Machined Circular Body

The visible design shows a thick, round, machined metal disc with smooth finished faces. That kind of construction usually indicates a component that must seat securely and distribute force evenly across a bolted connection. In heavy machinery, this is especially important in frame-related sections where constant movement, vibration, and shock loads are present.

Raised Center Section

One face includes a centered raised hub. This kind of feature often helps guide location, maintain alignment, or create a controlled seating surface between adjoining parts. Even without public engineering drawings, the geometry suggests a role beyond simple coverage.

Eight-Bolt Hole Pattern

The face shows eight equally spaced mounting holes. This balanced bolt layout supports stable fastening and more even load transfer across the part. On equipment such as Komatsu dozers, symmetry in fastening points is important because the assembly is exposed to repeated side loads and ground impact.

Thick Outer Profile

The side-view photos show a clearly substantial thickness rather than a thin hardware disc. That visual mass supports the idea that this is intended for serious structural use in a heavy-duty mounting area.

Where This Part Is Used

The strongest published association for this number is the D85 series, especially the equalizer bar and pivot shaft section. 3genexport sells it directly for the D85EX15 dozer and places it in the equalizer bar / bogie / pivot shaft category. 3genexport catalog snippets and other parts-catalog snippets place the same number inside pivot shaft or equalizer bar and pivot shaft assemblies on multiple D85 variants.

This assembly area is important because it supports load handling and stability across the machine frame. When parts in this section are worn, distorted, or poorly matched, the result can be looseness, uneven loading, accelerated wear in neighboring parts, and costly downtime during field operation. For that reason, buyers sourcing this component are usually not making a casual purchase. They are looking for a part that helps maintain machine integrity in demanding conditions.

Compatible KOMATSU Models

Public catalog snippets consistently connect this part number with selected Komatsu D85 bulldozer variants. The most commonly referenced models are:

• D85MS-15

• D85PX-15

• D85PX-15E0

• D85EX-15

• D85EX-15E0

• D85PX-15R

• D85EX-15R

Some catalog sources also show serial-based application ranges, such as D85MS-15 S/N 1006-UP, D85PX-15 S/N 1001-UP, D85EX-15 S/N 10001-UP, D85EX-15E0 S/N 11609-UP, and early D85PX-15R / D85EX-15R ranges. Because Komatsu dozers can differ by market, serial break, regional specification, or running changes, the safest purchasing method is always to confirm the full model and serial number before final order approval.

If your workshop handles D85-series maintenance, this number is especially relevant when servicing pivot shaft and equalizer bar related assemblies. It is a good candidate for inventory visibility because it attracts both exact-number searches and machine-model searches.

Weight of the Part

A current online listing gives the package weight for this number as 8.18 lbs (3.72 kg). Because that figure is presented as listing weight rather than a factory engineering sheet, the most accurate way to show it on your website is as an approximate weight of 3.72 kg. That is useful for freight planning, warehouse handling, and buyer expectations.

Why This Part Matters in Real Operation

On working bulldozers, the equalizer bar and pivot shaft zone deals with repeated stress from pushing loads, uneven terrain, turning resistance, shock input, and long operating hours in dirty environments. A part installed in this area must do more than just match a hole pattern. It must also support stable contact, accurate alignment, and consistent fastening over time.

That is why the 1545071180 / 154-50-71180 FLANGE KOMATSU has genuine commercial importance for repair teams. A poorly machined or dimensionally inconsistent part in a structural assembly can lead to difficult installation, imbalance in clamping force, premature movement, or faster wear in adjoining parts. By contrast, a correctly supplied part helps the machine go back into service with greater confidence.

From a buyer’s perspective, that means value is not only about the purchase price. It is also about the speed of fit-up, the ability to finish a repair without rework, and the long-term protection of surrounding components in the same assembly.

Commercial Search Value for E-Commerce

This part number has strong SEO potential because it can be searched in several ways. Buyers may use the continuous number 1545071180, the hyphenated form 154-50-71180, the market name flange, or the machine application D85EX-15. Seller listings prove that the same number is already being used in commercial search environments in exactly those formats.

For that reason, your product page should naturally support these search intentions:

1545071180

154-50-71180

154 50 71180

Komatsu D85EX-15 flange

Komatsu pivot shaft flange

Komatsu equalizer bar flange

Using these variants carefully improves discoverability for Google, Search GPT, AIO, GEO, and AEO style search behavior while keeping the content readable for real customers.

Technical Buying Notes

Part Number Formats

The published number appears in both continuous and hyphenated formats: 1545071180 and 154-50-71180. Both forms are widely used in listings and catalog references, so both should appear on the page.

Product Position

The part is associated with the equalizer bar and pivot shaft section on D85-series machines. That positioning indicates a structural or mounting role in a high-load area.

Market Naming

In direct product listings it is sold as a flange for D85EX15, while catalog-style references describe the same number within washer terminology inside the same assembly family. For e-commerce, keeping both naming styles in mind helps you capture more buyer searches without confusing the customer.

Approximate Weight

The published listing weight is about 3.72 kg.

Installation and Maintenance Guidance

Before ordering, always verify the full machine model and serial number. That step is especially important on D85-series machines because public parts references show multiple serial-based variations across D85MS, D85PX, D85EX, and their E0 or R derivatives.

Before installation, inspect the mating surfaces and the surrounding pivot-related assembly for damage, scoring, distortion, or bolt-hole wear. Clean all contact faces thoroughly and check the condition of associated bolts, seals, spacers, rings, and adjoining shaft components. If the surrounding hardware is already worn, simply replacing one part may not restore the assembly to stable working condition.

After the repair is completed, it is wise to check the assembly again after initial service hours. Early inspection can help detect seating issues, bolt loosening, or unwanted movement before they become larger maintenance problems.

Why Workshops and Dealers Buy This Number

There are several reasons this number is commercially valuable for spare-parts sellers and maintenance operations.

First, it sits in a part of the bulldozer that customers are willing to source carefully because failure in this zone can have wider service consequences.

Second, it benefits from mixed search behavior. Buyers search by part number, by application, by component name, and by dozer model. That gives the product page broader organic reach than many low-value consumables.

Third, it is visually distinctive. The round disc profile, raised center hub, and eight-hole pattern create a clear product identity in catalog thumbnails and marketplace listings. That helps users compare the visual part they removed from the machine with the replacement they are sourcing online.
