Abstract: A chain tensioner arm or chain guide includes a main body extending in a longitudinal direction and including side walls, each side wall defining a ledge. The main body has a first end including a first tab formed by a set of first grooves extending inwardly from the first end towards a center of the main body, and having a tab end. The tab end of the first tab includes a first protrusion extending away from the main body. The chain tensioner arm or chain guide also includes a shoe with a chain sliding surface on which the chain slides. The shoe includes a side protrusion extending in a longitudinal direction along each side of the shoe. The side protrusion fits into the ledge of the main body. Methods of assembling the tensioner arm or chain guide are also disclosed.
