Abstract: A tensioner system imparting tension to a chain comprising a pair of tensioner arms, at least one link piece, and a tensioner. The pair of tensioner arms have a pivoting end for rotation about a fixed pin, a link end, and a shoe with a chain sliding face. At least one link piece has a first end pivotally attached to the link end of each of the tensioner arms. The tensioner has a housing for receiving a piston with an end in contact with a pin that joins the second end of the link pieces together. When the piston of the tensioner is biased outwards from the housing, the end of the piston contacts the pin joining the link pieces of the tensioner arms, moving the tensioner arm toward a chain centerline and tensioning the chain equally on both sides.
