ABSTRACT:
An intake manifold assembly includes a housing, a shaft assembly, an intake insert, and a flange seal. Bushings are located at each end of the shaft and spaced along the shaft to absorb vibrations and provide a low friction surface for shaft assembly rotation. In addition, the bushings allow for differences in the thermal expansion of the shaft and the intake manifold housing. A bearing is located adjacent a shaft locator to provide a hard mounting surface for the shaft assembly when assembled with the housing.
