Embodiments herein provide formed wire tie strap for a saw chain. Embodiments also provide a saw chain including one or more formed wire tie straps. The formed wire tie strap may include a body with one or more integrated rivets extending from the body. In some embodiments, the body may be substantially flat. The rivet may include a rivet head configured to engage a rivet hole of an opposing tie strap and a shoulder configured to engage a rivet hole of a connecting link, such as a drive link. Some embodiments of the formed wire tie strap may include a pair of integrated rivets extending from the body. Some embodiments may include a rivet hole disposed in the body of the formed wire tie strap.

A method of assembling a clutch includes assembling a wedge chain by connecting a plurality of wedges together with links such that the wedges are movable relative to each other, and wrapping the wedge chain around an inner race. The method further includes connecting an end one of the links to an end one of the wedges to secure the chain to the inner race. The may also include installing the inner race into an outer race such that the wedge chain is radially disposed between the inner and outer races.

A chain includes a plurality of inner links and a plurality of outer links. Each of the inner links includes a pair of inner plates each having a bush hole and a bush. The bush includes both end portions which are press-fitted into bush holes of the pair of the inner plates. Each of the outer links includes a pair of outer plates and a pin. A diametric dimension in a pitch direction of an inner diametric surface of the bush is constant along an entire axial length of the bush. A diametric dimension in a height direction of the inner diametric surface at each of the both end portions of the bush is smaller than a diametric dimension in the height direction of the inner diametric surface at an intermediate part of the bush located between the pair of inner plates.
