TM 9-2910-226-34 Figure 3-50. Fuel control lever identification (code G pump). (3) Final inspection of the fuel control unit will be accomplished at fuel injection pump calibration c. Assembly. Refer to figure 3-47 and install plunger sleeve pin (A). Install new control unit packing (B). 3-24. Repair of Fuel Density Compensator Assemblies. NOTE There are no service or spare parts for fuel 3-36 density compensator assemblies. Do not disassemble. a. Discard original type (2910-017-9776) and retain other types (2910-907-0665 or 2910-125-3793) for possible reuse. b. New compensator assemblies are furnished calibrated and do not have to be checked for calibration before installation. If it should be necessary to check operation of a new or used compensator, it may be functionally inspected in the following steps. (1) Manually operate stop plate (fig. 3-51) through full travel. It must have smooth action with no indication of sticking. (2) Apply 35-45 psi fuel pressure to compensator fuel inlet (fig. 3-51); and stop plate must move to the , up position. (3) Manually depress stop plate to full travel. Note that remaining travel, when pressurized is 0.040 to 0.060-inch. This will cover a fuel range of - DF-1 and DF-2. If travel is more than 0.060-inch, replace the compensator. (4) Plug fuel inlet and apply 10 psi fuel pressure to fuel outlet connection (fig. 3-51) and maintain for approximately one minute.
