Abstract

A chain guide and tensioner for guiding and applying tension to a chain may include a first tensioner arm, a second tensioner arm being positioned in a spaced relationship with respect to the first arm member, a shaft member for connection to the first arm member, and a roller member including a groove for guiding the chain. The roller member may include a pair of opposing flanges to define the groove and the height of the opposing flanges may be at least the height of the chain. The first tensioner arm may be biased by a biasing member, and the biasing member may include a spring. The biasing member may include a shock absorber, and the roller member may be positioned by a collar member. The collar member may move along a roller bushing member to adjust the roller member to be aligned with the chain, and the spring may be positioned over a spring bushing member. The spring bushing member may maintain a spaced relationship between the first tensioner arm and the second tensioner arm, and the second tensioner arm may be connected to the vehicle. The flange may include a chamfered edge.
