ARMY TM 9-2815-255-24 AIR FORCE TO 38G1-95-2 MARINE CORPS TM 2815-24/4 bh. Install throttle shaft assembly (18) partially through its bore in housing.  Slide barrel and spacer (20) and throttle shaft lever (19) over throttle shaft so that projection in lever (19) engages rear key way on shaft.  Position forked end of throttle lever so it straddles guide stud, refer to FIGURE 3-84. bi. Slide  damper  barrel  assembly  (41)  over  damper  piston  (43)  and  slide  throttle  shaft  assembly  (18)  through damper barrel (41), throttle shaft spacer (20), and throttle lever (19). bj. With throttle shaft assembly (18) in low idle position and governor control spring relaxed, forked end of throttle lever (19) should straddle and engage flats on bushing (8, FIGURE 3-46).  Adjust low idle screw (39, FIGURE 3- 45) until forks of lever make contact with flats on bushing.  Tighten low idle lock nut (40) 30 to 35 in-lbs (3.5 to 4 Nm). FIGURE 3-84.  Installing Throttle Shaft Assembly (Typical) bk. Turn adjusting cap (2, FIGURE 3-46) counterclockwise (from transfer pump end) to end of adjustment, then turn clockwise  1/16  of  a  turn.    This  prevents  binding  between  control  rod  bushing  (8)  and  throttle  shaft  lever  (19, FIGURE 3-45). bl. Install shutoff shaft assembly (30) through its bore using a slight rotary motion so as not to damage seal ring (22).
