The Fabco 45-tooth upper helical gear, part number 4320682 or 432-0682, is the OEM upper shaft helical gear listed in the illustrated parts manuals for Fabco transfer case models TC-142, TC-1421, and TC-143. The earlier part number 432-682 cross-references directly to this updated designation. Helical-cut tooth geometry provides smoother, quieter engagement compared to straight-cut gears, making this an exact fit for the upper shaft position in these Fabco units.
