A method of maintaining proper tension in belt or chain drive systems comprising attaching one end of a tensioning assembly to a mounting surface so as to permit unrestrained pivotal movement but negligible axial movement and positioning the opposed end adjacent the drive system belt or chain. A torquing tool is then applied at the mounting point and the assembly is rotated about a central axis until a predetermined torque value is attained and the assembly is locked against pivotal movement. The tensioner for carrying out the method includes an elongate arm with an idler pulley attached to one end. The opposed end receives a mounting member for securing the arm to a supporting surface first in pivotal relationship thereto and then in locked relationship. The mounting member also serves as a torquing member for applying the predetermined torque value.
