  • Patent number: 6216551
    Abstract: An improved transfer lever for a 4WD vehicle is arranged such that the position of a knob attachment piece remains the same even when used with transmissions of two different lengths. The difference between the two lengths is a distance D. This retains the knob attachment piece in an optimal shift position can be attained. The transfer lever is bent, proximate its base, at an angle that places the knob attachment piece a distance D/2 from a centerline of its base. The transfer lever is installable in two orientations 180 degrees apart. When the longer transmission is used, the transfer lever is installed to position the knob attachment piece D/2 forward of the centerline, and when the shorter transmission is used, the transfer lever is installed to position the knob attachment piece D/2 rearward of the centerline, whereby the knob attachment piece is positioned in the same fore and aft location regardless of which transmission is used.
