How do I confirm CF-20621N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Barber Greene BG8820, Barber Greene BG8820B, Caterpillar CS66B and related applications.

Which fields matter most?

Start with Voltage: 24V, Amperage: 100A, Rotation: CW, Pulley Class: W/O PULLEY, then cross-check OE numbers Caterpillar 20R-4763, 378-9640, Claas 0005011080, 05011080.

What if I only have a photo or partial number?

Share label photos, drive-end and connector shots, and any partial number or Lester Numbers 20621, 21827. That usually narrows the match quickly.
