Buy Gearbox for 2007 Winnebago Sightseer RV Steps | Kwikee & Lippert Parts

Do not choose a gearbox from the 2007 Sightseer model year or the chattering symptom alone. Partial travel does not prove that the gearbox is the only failed component, or that the motor and controller are healthy. A gearbox/linkage can be a separately identified service part on some Kwikee systems, but the installed step series, generation and linkage must be verified first.

Lippert's Kwikee manual CCD-0001625, revision 09.04.24, pages 3–5 distinguishes pre-IMGL, IMGL and IMGL II components and different A/B/C linkage applications. For the covered IMGL systems, a motor/controller replacement may require a matched upgrade rather than mixing generations; Series 23 has a separate chart. The coach year does not establish which assembly is fitted today.

The three product cards below are identification references, not confirmed compatible recommendations. Part 379160 is the curved A gear/linkage in the manual's applicable series charts. Part 379147 is a motor with screws, not the complete motor/gearbox assembly described in the earlier answer. Part 676061 is also a motor with screws with its own generation/application limits. They are different service items, not interchangeable solutions to chattering.

Record the step assembly label/series and part number, motor and controller identifiers, linkage shape, connectors and mounting geometry. Compare those with the exact manufacturer parts chart and service procedure, including any prior upgrades. Have a qualified technician diagnose the installed system before ordering or working on moving steps. The correct gearbox, need for other components and repair outcome remain unconfirmed.
