b) After making sure that the wire is in the inner groove of the wire pulley, pass it down over
the idler pulley to the underside of the wire driving pulley (but do not seat the wire in the
idler pulley groove). The wire should be wound around the driving pulley 5-1/2 turns,
beginning from the idler pulley side of the wire driving pulley and ending on the opposite
side (see Fig. 4-6).

In performing the above procedure, it is possible to seat the wire in the idler pulley groove
during the process, rather than at the end. Should this be done, however, it is necessary to
loosen the tension spring tiedown bracket before beginning the installation; and at the com-
pletion of the installation, the bracket must be repositioned for proper wire tension.
