Abstract
A vibration isolated shift lever comprises a control lever, a shift plate, a transmission plate, a transmission lever and resilient bushings located between the shift plate and transmission plate. The shift plate triangularly shaped and is provided with three shift plate apertures one being located at each of the apexes of the triangular shift plate. The transmission plate provided with a transmission lever receiver that is bolted to the transmission lever. The transmission plate is triangularly shaped and provided with three transmission plate apertures that are located at the apexes of the triangular transmission plate. The shift plate and the transmission plate are aligned so that the three shift plate apertures are lined up with the three transmission plate apertures. Three mounting bolts extend through the lined up shift plate apertures and transmission plate apertures. Each of the bolts is provided with a resilient rubber bushing. The resilient bushing is positioned between the shift plate and the transmission plate with the resilient bushings extending into and through the respective shift plate apertures. A rigid sleeve is located in the central tunnel of the bushing. The rigid sleeve is shorter than the central tunnel. The mounting bolts are provided with a washer that engages the rigid sleeve and the resilient bushing. A cap portion of the resilient bushing is positioned between the shift plate and the transmission plate. The resilient bushing is compressed by the application of a lock nut engaging the mounting bolts on the other side of the transmission plate. Compressing the bushing radially deforms the sleeve portion of the bushing outwardly between the washer and the shift plate.
