Abstract: A tensioner that includes a mount, a pair of tensioner arms, and a spring. The mount defines a movement axis. Each tensioner arm assembly has a first tensioner arm, which is coupled to the mount for sliding movement about the movement axis, a tensioner pulley and a spring guide. The tensioner pulley and the spring guide are coupled to an associated tensioner arm for movement therewith. The spring is mounted on the spring guides and biases the tensioner arm assemblies about the movement axis in respective directions that urge the tensioner pulleys toward one another.
