Abstract
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.
