Abstract
A method of retrofitting a window covering with a motorized tilting assembly. The method includes removing a tilt rod from a blinds tilting mechanism and introducing the motorized tilting assembly into the blinds tilting mechanism. The assembly includes a motor, a gearbox having an internal enclosure and an external enclosure, and an output shaft. The internal enclosure encloses gears, and the external enclosure encloses the internal enclosure. The output shaft includes a through-channel and extends through the internal enclosure and the external enclosure. The method further includes: selecting a tilt rod adapter having an internal shape complementary to the tilt rod and an external shape complementary to the through-channel of the output shaft; inserting the tilt rod adapter into the output shaft; and reinstalling the tilt rod such that the tilt rod passes completely through the output shaft and the tilt rod adapter.
