Flywheel with adjustable weights

Abstract

A flywheel capable of accommodating various automotive engines and transmission systems having different points of balance. The flywheel has a hub portion for securing to a crank shaft output arbor and a web portion integral with said hub portion on the periphery of said web portion and a weight is secured to the flywheel in such a way that the effective weight and effective position thereof is adjustable to a plurality of discrete positions, each of which is precisely correlated to each of the different points of balance of said various automotive engines having different points of balance, respectively. In a preferred embodiment, the weight is angularly and radially adjustable and is guided to each discrete position by at least one slot formed in the web, and a bolt passing through said weight and the slot. The bolts passing through the slots have safety attaching indentations therein for non-slip positive attachment of the weight in the different positions. An adaptor ring press is fitted within a hole in the hub for accommodating different output arbors of engine crank shafts and the adaptor ring and hub have cut-outs forming an elongated alignment slot for an alignment pin on the crank shaft arbor. A hole or aperture formed 180 degrees opposite the slots has an area of sufficient size as to provide a neutral balance condition when said weight means has been removed therefrom.
