Before installing onto a pulley, it is always a good idea to place each belt into its pulley groove. Figure 58.4 is an illustration of how a V-belt should sit in the pulley groove. The top of the belt should be within 1 16-inch of the outer surface of the pulley.If the belt top is deeper in the groove, the groove or belt is worn, which can shorten the remaining belt life by as much as 50 per cent.
