A fastenerless chain snubber is provided that consists of a snubber body, and one or more attachment arms that form positioning blocks. The snubber is positioned in a housing by channel surfaces in the chain housing that locate the positioning blocks of the snubber. The snubber is firmly secured during chain operation by the substantial contact between the snubber attachment arm surfaces opposite the chain cover and the corresponding surface of the installed chain cover.

A chain and sprocket system includes a plurality of chains and sprockets. The system includes a central shaft, two chains, and two identical sprockets. Although the two sprockets have identical size, shape, and features, they can be assembled onto the central shaft in different orientations. These orientations are achieved by rotating one sprocket with respect to the other. Assembling one sprocket onto the shaft in a different orientation from a second sprocket results in a system where the outer sprocket teeth of one sprocket are phased with respect to the outer sprocket teeth of the other sprocket. In this way, a phased chain and sprocket assembly is composed of identical sprockets, which eases manufacture and assembly.
