Abstract

Method and apparatus for adjusting tension on a timing belt of an engine. The engine includes a driving pulley on its crankshaft, a driven pulley on its camshaft, an auxiliary pulley, a timing belt bridging over the pulleys and a tension pulley pressing against the belt at one side. The driving pulley is first reversely rotated while the driven pulley is held fixed in position thereby tensioning the portion of the belt between the auxiliary pulley and the driven pulley. The driving pulley is then rotated normally to overtension the tension side portion of the belt while the tension pulley is advanced to take up any slack. Thereafter, the tension pulley is retracted while the driving pulley is reversely rotated until deflection of the tension side portion of the belt reaches a predetermined target adjustment value. The tension pulley is then fixed in position.
