Abstract
Abstract A mobile construction vehicle comprises a frame having a transmission assembly mounted on a rearward end thereof in cantilevered relationship. The transmission assembly comprises a bell housing solely mounted on an annular support of the transmission by first anti-vibration and noise suppressing means which isolates the housing from metallic contact with the support member. If so desired, second anti-vibration and noise suppressing means may be utilized to solely mount the support member on the frame to also prevent metallic contact therebetween.
