Abstract:
1. An adjustable camshaft sprocket assembly comprising: a hub adapted to be secured to an associated camshaft, said hub comprising a flange; a sprocket body selectively engaged with said hub flange using at least one fastener, wherein said sprocket body is selectively angularly adjustable relative to said hub flange when said at least one fastener is loosened and said sprocket body is angularly fixed relative to said hub flange when said at least one fastener is tightened; a stud-receiving opening defined in one of said hub flange and said sprocket body, and a tool-receiving opening defined in the other of said hub flange and said sprocket body, said tool-receiving opening aligned with said stud-receiving opening and adapted to receive a body portion of an associated adjustment tool, and said stud-receiving opening adapted to receive an eccentric stud of the associated adjustment tool, wherein either the stud-receiving opening or the tool-receiving opening is elongated to allow relative sliding movement of the associated adjustment tool therein, wherein rotation of the associated adjustment tool when its body is located in the tool-receiving opening and its eccentric stud is located in the stud-receiving opening causes relative angular movement between said hub and said sprocket body when said at least one fastener is loosened.
