ABSTRACT:
An assembly of housings is secured is secured together by a plurality of bolt members. The assembly is subject to a source of vibration, such as an internal combustion engine. To ensure the natural frequency of the bolt is outside the operating range of the engine, tolerance support rings are installed to reduce the effective length of the bolts and thereby increase the natural frequency.
