Abstract:
1. An air induction system for supplying compressed induction fluid to an intake manifold of an internal combustion engine wherein the engine includes a rotatable crankshaft, said induction system comprising: a blower including a rotatable impeller operable to compress induction fluid for the engine when rotated; and a drive assembly operable to drivingly connect the impeller to the crankshaft, said drive assembly including a bracket, a bearing tube shiftably coupled to said bracket, a shaft rotatably supported in said tube, a pulley coupled to said shaft, and an endless element entraining said pulley for rotation therewith, said shaft being eccentrically positioned in said tube, said bearing tube including a generally cylindrical body and an internal bore extending axially through said body, said bore being eccentrically positioned relative to said body, said bracket including a tube-receiving aperture formed therethrough and at least one elongated slot positioned adjacent said aperture, said bore and shaft extending through said aperture, said slot being arcuate, said drive assembly further including a fastener coupled to said body and extending through said slot, said body and fastener shiftable relative to said bracket between at least two differing positions wherein said bore rotates relative to said bracket when said body is shifted between said positions, said fastener being adjustably coupled to said body and operable to selectively prevent said body from shifting out of a respective one of said positions.
