HeavyEQ parts intelligence
Research first. Identify the installed component. Confirm the application.
Model discovery • Exact part fitment requires machine identification
Dash-24 intelligent-machine-control configuration · United States reference. Production-year bounds have not been established in this parts catalogue.
View the accepted equipment specifications →Blade, shoe width, undercarriage, cab, drawbar, winch, ripper and grade-control equipment can materially change operating weight and dimensions. Use the applicable configuration sheet.
Equipment-class discovery • Systems vary with configuration
Identify the track system, blade arrangement and drive architecture independently. A dozer family can include materially different configurations.
Record installed track geometry, blade linkage and ripper configuration. Preserve model suffixes such as XE and documented assembly codes when requesting a drivetrain or control component.
Blade width and operating weight are not a parts application. Do not collapse parallel drive variants or assume that a track component fits every machine in a family.
Start with the manufacturer, model suffix and installed equipment. The following specialist subjects help describe a sourcing request; they do not identify a specific orderable part.
Record the installed assembly identification, its position and configuration. Ask the supplier which documentation connects the proposed replacement to that assembly.

For a used or rebuilt component, ask for its donor-unit provenance, inspection record, repair scope and any remaining identification marks. A donor model is context, not proof of fitment to another machine.
These are equipment-class discovery subjects. Confirm whether each is installed on the actual unit.

Equipment specifications and generation evidence stay on the accepted model page. They are not proof that a specific replacement part fits.

Use the accepted model identity to explore component families. Confirm the installed assembly, configuration and serial/PIN with the manufacturer before ordering.
Technical research & specification evidence
Original machine-model research; source-specific market and generation qualifiers retained; actual installation unknown
Use the existing model record to organize component research, retain qualified manufacturer observations and identify the evidence still needed for the actual installed equipment.
The reviewed first-party reference records Published US engine designation: Komatsu SAA4D107E-3; Published US emissions qualifier: EPA Tier 4 Final. Record the exact engine plate designation and its serial or build list separately from the machine PIN. Check whether the engine is original, a later service replacement or a rebuild with retained accessories. An emissions label and the machine brochure help identify the appropriate document set; neither identifies every internal or external engine part. Official indexed global brochure names SAA4D107E-7 while current US page names -3. Global brochure URL returns404; no current global full-text claim or universal suffix correction accepted.
The accepted HeavyEQ model identity remains Komatsu D51PXi-24, with generation recorded as Dash-24 intelligent-machine-control configuration and regional context recorded as United States reference. This identifies the research owner rather than every machine bearing the badge. Keep each cited source edition and its own market qualification beside the observation. A Canadian model table, a Tier 4 Final product guide or a current United States webpage must not be silently generalized into a worldwide specification. Historical revisions and dealer-installed or rebuilt equipment can require a different document set. Preserve discrepancies for review instead of choosing an apparently convenient number or suffix.
Record machine identity and component identity in separate private evidence records. Collect the applicable machine PIN information, a readable assembly tag, engine serial or build list where relevant, and evidence of what is currently installed. Check service history for replacement assemblies and retained accessories. Use those records to request the correct manufacturer application or service documentation. Share only the minimum necessary identifiers through an appropriate private process. The model context here does not certify an installation, authorize a substitution or identify a purchasable service part. No new exact assembly number, serial-specific fitment or supplier offer is established by this research.
Published values retain their exact reference scope. Empty fields mean the value has not been established; they never mean zero. General model associations do not establish installed or serial-specific fitment.

United States reference; Dash-24 intelligent-machine-control configuration; contextual research only, no installed-component identification
Identify the Komatsu D51PXi-24 machine generation and the actual electrical assembly as separate research subjects. This investigation preserves the accepted model context and records what the available evidence can establish about gnss receivers, antennas and machine-position interfaces.
D51PXi-24 IMC feature verified; separate IMC overview gives integrated-system context. A GNSS receiver, antenna and machine guidance application have different identities and responsibilities. A positioning product can provide useful data without establishing machine control accuracy, compatibility or a safe automated function. Research the receiver variant, antenna arrangement, correction/service context and installed application separately, preserving the machine maker's integration evidence and the conditions behind any later performance claim. For Komatsu D51PXi-24, retain receiver positioning vs machine guidance/grade control system as observed evidence rather than completing the record from a similar machine. No machine-grade accuracy, compatibility or survey certification without complete system.
Komatsu D51PXi-24 retains its existing canonical research owner. The investigation concerns gnss receivers, antennas and machine-position interfaces. Read the source in its stated market and generation; a currently advertised feature can describe an option, a package or a later configuration. Record the issuer and complete designation on the actual assembly separately from the machine name. A housing mark, a general technology label and an orderable service identity answer different questions. Missing identifiers stay unknown. A prior repair or assembly replacement can also make the original build information insufficient to identify what is present now.
Use the existing equipment specifications for the retained model and generation. A general model association supplies discovery context; it does not prove the particular controller, sensor, harness or operator device installed on an individual machine. A qualified review should connect the actual hardware revision, harness and connector configuration, signal interpretation and applicable application or calibration evidence. Keep full PIN/serial identifiers, software credentials and service access private. Neither the absence of a fault nor a matching supply voltage establishes interchangeability. This page does not provide energized tests, wiring adaptation, programming steps or a replacement approval. The linked component research explains which evidence belongs in each part of that review.
Published values retain their exact reference scope. Empty fields mean the value has not been established; they never mean zero. General model associations do not establish installed or serial-specific fitment.
