ABSTRACT:
An intake manifold assembly includes a housing, a shaft assembly, and an intake insert. The shaft assembly has a metal shaft with bearings located at each end to provide hard mounting surfaces for the shaft assembly when assembled in the housing. The bearings support the shaft within the housing and allow the shaft to freely rotate. Bushings are spaced along the shaft to absorb vibrations and assist is providing a low friction surface for shaft assembly rotation. Journal pockets in the housing and in the intake insert surround the bushings. Isolators located within the journal pockets and housing surround the bushings and assist in dampening vibrations.
