right of the idler pulley and to the left, around the rear, and to the right of the capstan.
(9) Holding the idler pulley in this position, reach down and pull the forward portion of the trim
cable over the idler pulley and seat it in the top cable groove on the idler pulley. The left trim
cable should now be routed as shown in Figure 5.
