ARMY TM 9-6115-464-34 AIR  FORCE  TO  35C2-3-445-2 NAVY  NAVFAC  P-8-624-34 (o) At a pump speed of 200 rpm, repeat steps (n) and (o). Delivery shall be 2 mm3 maximum. (p) Check minimum cranking speed delivery as follows: 1. Check transfer pump for 8 psig minimum and close the shutoff valve to gauge. 2. Check for 35 mm3 per stroke, minimum, at 75 rpm. (q)  Remove  pump  from  test  stand. g. Installation. (1)  Remove  fuel  injector  nozzle  from  No.  1  cylinder. (2) Turn the engine over until the 20 degree before top dead center (BTDC) mark on the flywheel is lined up with the timing mark on the flywheel housing, and No. 1 cylinder is on compression stroke. (3) Remove the timing hole cover on the injection pump and rotate the pump shaft until the timing marks line up. NOTE The pump shaft should never be turned backwards to align internal timing marks. (4)  Install  pump  on  engine  and  install  attaching  hardware. (5) Recheck flywheel timing marks then rotate the fuel pump body until the pump timing marks are exactly in line. Tighten pump attaching nuts to 35 to 40 ft-lb. NOTE After fuel injection pump is installed, rotate engine 180 degrees backwards. Then rotate engine in correct rotation until 20° BTD timing marks on the flywheel appears in flywheel timing hole and recheck pump timing marks. (6)  Install  pump  timing  hole  cover. (7)  Install  fuel  Injection  lines. NOTE New injection pumps received from supply have a high idle adjustment of 1,860 rpm for 60 HZ applications. Installation on 400 HZ generator sets requires resetting the high idle adjustment screw (29, figure 3-21 ) to 2,250 rpm Adjustment is accomplished using an engine speed tachometer, with actuator linkage (6, figure 3-20) disconnected, the shutoff lever (21, figure 3-21 ) in the on-fuel condition, then manually operating the throttle lever (35, figure 3-21 ) against high idle stop. NOTE When replacing the fuel lines, always use new gaskets. (8)  Connect  throttle  linkage  and  stop  control. (9)  Connect  fuel  supply  and  return  lines. (10) Replace No. 1 fuel injection nozzle in No. 1 cylinder. (11) Bleed the air from the fuel system. 3-65
