HeavyEQ parts intelligence
Research first. Identify the installed component. Confirm the application.
Model discovery • Exact part fitment requires machine identification
Current 430 manufacturer record · United States / North American reference. Production-year bounds have not been established in this parts catalogue.
View the accepted equipment specifications →Standard and extendable dipper configurations, loader linkage, bucket, 4WD, tires, controls and auxiliary hydraulics can change weight and working range.
Equipment-class discovery • Systems vary with configuration
A backhoe combines loader, rear digging equipment and stabilizers on one carrier. Identify the working end and joint or cylinder position explicitly.
Document standard or extendable dipper, installed coupler/work tool, stabilizer arrangement and axle or transmission identity. A loader lift-cylinder request is distinct from a backhoe boom-cylinder request.
Do not infer hydraulic kit fitment from digging depth or a broad model generation. Cylinder revision and installed options require confirmation.
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.
