Abstract
A chain tensioner assembly includes a bracket with a main wall and a ramp surface. A blade assembly is connected to the bracket and includes a blade located adjacent the main wall of the bracket. The blade includes: (i) a first blade end with a pivot aperture; (ii) a second blade end contacting the ramp surface; and, (iii) a central blade portion that extends between the first and second blade ends. The central blade portion includes a chain engaging surface. A first spring-retaining slot is located in the first blade end and includes inner and outer open sides that open respectively through inner and outer faces of the blade. A second spring-retaining slot is located in the second blade end. A spring includes a first end located in the first spring-retaining slot, a second end located in the second spring-retaining slot; and, a central portion that abuts the central blade portion. A pivot fastener extends through the pivot aperture and obstructs the outer open side of the first spring-retaining slot such that the pivot fastener captures the first end of the spring in the first spring-retaining slot.
