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 by at least one fastener that non-rotatably connects said sprocket body to said hub flange when said at least one fastener is tightened and that allows relative rotation between said sprocket body and said hub flange when said at least one fastener is loosened; a stud-receiving opening defined in said hub flange and a tool-receiving opening defined in 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 a projecting eccentric stud of the associated adjustment tool, wherein the stud-receiving opening is elongated for relative sliding movement of the eccentric stud of the associated adjustment tool therein, and 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.
