17A5012112 / 17A-50-12112 EQUALIZER BAR KOMATSU

The 17A-50-12112 EQUALIZER BAR KOMATSU is a heavy-duty undercarriage support component used on selected Komatsu D155 bulldozers. Public parts references identify 17A5012112 and 17A-50-12112 as an equalizer bar, and seller pages connect the same number most clearly with D155AX-3 and D155AX-5 applications. Published catalog-style references also show an approximate weight of 235 kg, which fits the scale of the part shown in your images.

From the product photos, the 17A-50-12112 EQUALIZER BAR KOMATSU has the form expected from a major load-bearing dozer part. The long reinforced body, oversized end-eye sections, and heavy center mass all suggest a component built to absorb force and maintain alignment across a large working assembly. The crate images add another practical signal: this is not a small service item but a serious structural part prepared for industrial export handling.

At 3GEN Export, we supply the 17A-50-12112 EQUALIZER BAR KOMATSU as an OEM supplier and deliver all over the world in 5 working days. For workshops, fleet managers, resellers, and contractors, that means a faster route from parts identification to machine recovery.

Product Overview

The 17A-50-12112 EQUALIZER BAR KOMATSU belongs to the equalizer bar, bogie, and pivot shaft family on Komatsu bulldozers. 3genexport lists the number in that category and markets it directly for the D155AX-5 dozer, while other commercial catalog sources list the same number as an equalizer bar assembly for D155AX-3 and D155AX-5. Those references place the part in a structurally important section of the machine rather than in a secondary frame bracket group.

That matters because a part in this location supports the machine where frame movement, undercarriage articulation, and heavy working loads meet. Buyers searching for 17A5012112 are usually not looking for a simple replacement bolt-on panel. They are looking for a major support member that affects how the dozer carries load and handles field stress over time.

The commercial search value is also strong. Some buyers search the continuous number 17A5012112. Others search the hyphenated version 17A-50-12112. Others search by machine family, using phrases such as D155AX-5 equalizer bar or Komatsu D155 equalizer bar. A well-written page should support all of those search habits without repeating the same wording unnaturally.

What the Images Show

Long reinforced main body

The most obvious visual feature is the long beam-style body. It is not flat or lightweight. It has a reinforced shape designed for strength, which is exactly what buyers expect from a large dozer equalizer bar. The geometry suggests a part intended to resist flex while handling repeated shock and working load.

Large end-eye sections

Both ends of the 17A-50-12112 EQUALIZER BAR KOMATSU have large circular eye sections. These areas are where fit and wear usually matter most because they work with shafts, pins, bushings, or related pivot components. On a part in this size class, end-eye accuracy is critical for dependable assembly behavior.

Heavy center section

The middle of the component is visibly thicker and more substantial than a simple straight beam. That extra mass suggests a design built to handle concentrated stress in the central load path of the assembly.

Export-ready crate packing

The wooden crate and protective wrapping shown in the images are also useful selling details. They reflect the reality of the part’s size and handling requirements. Buyers immediately understand that the 17A-50-12112 EQUALIZER BAR KOMATSU is prepared as a serious export item, not as a light parcel shipment.

Compatible KOMATSU Models

The clearest publicly visible fitment references connect the 17A-50-12112 EQUALIZER BAR KOMATSU with Komatsu D155AX-3 and D155AX-5 bulldozers. 3gen lists the number as EQ BAR ASS for both models, and 3genexport markets it specifically for the D155AX-5 platform. Broader parts-database references also connect the number with the wider D155A and D155AX family.

For a product page, the most dependable way to present compatibility is:

Commonly referenced models

D155AX-3
D155AX-5

Broader public family references

D155A family
D155AX family

Because large bulldozer assemblies can differ by serial range, service history, and machine revision, final model and serial confirmation is still the safest step before ordering. That is especially important on machines that have undergone earlier undercarriage or frame-related repair work.

Weight of 17A-50-12112 EQUALIZER BAR KOMATSU

Public parts references consistently show the 17A-50-12112 EQUALIZER BAR KOMATSU at approximately 235 kg. That figure appears in 3genexport spare-parts listings and in marketplace references for the same number. For freight planning, workshop lifting, and packing expectations, this is the most practical published weight to use.

Approximate weight

235 kg.

That figure also matches the visual impression from the photos. This is clearly a substantial structural component rather than a light support piece.

Technical Details

Part number formats

The two main search formats are 17A5012112 and 17A-50-12112. Public catalog and seller references use both formats, so both should appear in the page content for better discoverability.

Product type

Public sources identify the part as an equalizer bar or equalizer bar assembly.

Product group

The 17A-50-12112 EQUALIZER BAR KOMATSU is grouped under equalizer bar, bogie, and pivot shaft in public aftermarket listings.

Related assembly context

Public equalizer-bar section references for D155AX-5 also show related parts such as shafts, covers, and other components in the same main frame and related-parts group, which confirms that this part belongs to a larger structural assembly rather than functioning alone.

Why This Part Matters in Operation

A Komatsu D155-class dozer works under constant pushing force, ground impact, torsional stress, and undercarriage movement. In that environment, the 17A-50-12112 EQUALIZER BAR KOMATSU matters because it belongs to the support system that helps manage those forces in a controlled way. Public references consistently place the number in equalizer bar and pivot-related product groups, which matches the heavy-duty role suggested by the product design.

When a part like this is worn, cracked, or dimensionally compromised, the problem often extends beyond one damaged component. Extra movement can affect nearby shafts, bushings, covers, and other related hardware. That is why the 17A-50-12112 EQUALIZER BAR KOMATSU is important not only as a replacement part but as a foundation for restoring the wider assembly.

For fleet owners and workshop teams, this is the real commercial value of the part. It supports better structural stability in one of the most demanding areas of the machine and helps protect the service life of surrounding components after repair.

Benefits of a High-Quality Replacement

Better fit during installation

A properly made equalizer bar helps reduce correction work during assembly. On a part weighing more than 220 kg, predictable fit is not a small advantage. It can save workshop time and reduce frustration during lifting and positioning.

Improved assembly stability

Because the 17A-50-12112 EQUALIZER BAR KOMATSU works in a major structural zone, dimensional stability matters. A dependable replacement helps the wider assembly return to a more secure operating condition.

Reduced risk of follow-up wear

When the main support part aligns correctly, nearby shafts, bushings, pins, and covers are less likely to carry uneven stress caused by a worn or distorted member.

Strong search value online

This part number is commercially valuable because buyers search it by exact number, by hyphenated number, and by machine model. That makes a strong product page useful for both direct-parts searches and broader Komatsu dozer parts discovery.

Installation Guidance

Before installing the 17A-50-12112 EQUALIZER BAR KOMATSU, confirm the machine model and serial range. Public references most clearly support D155AX-3 and D155AX-5, with broader D155 family references also appearing in parts sources. Verifying the exact machine before ordering is the safest approach.

During installation, inspect the surrounding assembly carefully. Public equalizer-bar section references show that this part sits in a broader main-frame and related-parts area with nearby shafts and covers, and seller listings place it in the bogie and pivot shaft group. That means related wear parts should be checked at the same time instead of assuming the bar alone is the whole repair.

Because the part weighs approximately 235 kg, safe lifting equipment and careful workshop handling are essential during fitment.
