What these pages represent- Every relationship comes from a manufacturer-published interchange/cross-reference source or verified successor notice.
- Each exact model page cites the source and preserves its claim scope.
- Multiple publishers can map different Brook Hansen S3 Series configurations to different target families.
What still needs verification- Ratio, torque, motor/input, bore or shaft, mounting dimensions and accessories.
- Service factor, duty cycle, starts, shock load, lubrication and environment.
- Any source-specific caveat such as mounting differences or required hardware changes.
