Technical Notes
The HE400VG and HE431VE designations indicate variable-geometry turbine technology, which typically helps manage airflow efficiency in heavy-duty applications. The visible side-mounted actuator with an electrical wiring harness suggests an electronically controlled unit; verify the actuator type and related electrical detail pinout against your existing assembly. The square exhaust flange with four bolt holes and clamp-style housing fasteners are visible features that help confirm physical alignment during installation. Since specific internal wheel dimensions and material grades are not provided, cross-check the compressor and turbine wheel specifications against your service manual. Confirm the electrical related electrical detail compatibility and mounting orientation before finalizing your order.
