ABSTRACT:
An arrangement for attaching a blade to a shaft for use in intake manifolds, uses fasteners that create a load on the blade. Fasteners are inserted through fastener holes in the blade and through shaft holes in the shaft. Once inserted outward pressure by the fastener on the shaft and the blade places the assembly under a constant load. The load prevents the shaft and the blade from vibrating against each other during engine operation. The same attachment method can also be used to retain and bias a shaft locater to the shaft.
