ARMY  TM  9-6115464-34 AIR FORCE TO 35C2-3-445-2 NAVY  NAVFAC  P-6-624-34 (1) Refer to the Operator and Unit Maintenance Manual and drain the day tank assembly. (2) Disconnect injector return lines (1 and 2, figure 3-20) and remove tee (3). (3) On precise sets, remove self-locking nut (4) and screw (5) to disconnect hydraulic actuator linkage (6). On utility sets disconnect the manual speed control. NOTE When fuel pump is removed from the engine for repair, the throttle lever should be tied in the wide open position while it is in transit or storage. This prevents the governor weights from dislodging inside the pump housing. (4)  Disconnect  inlet  fuel  line  (7)  and  remove  elbow  (8). (5) Refer to the Operator and Unit Maintenance Manual and disconnect fuel injector lines. (6) Remove screws (9), timing Iine cover (10), and gasket (11). (7) Using a suitable wrench on the crankshaft pulley, bar the engine over in the direction of rotation until the timing line on the governor retainer hub aligns with the timing line on the pump cam. (8)  Remove  nuts  (12)  and  Iockwashers  (13). CAUTION Do not allow the pump to “cock” as it is removed, as damage to the pilot tube will result. (9) Carefully slide fuel injection pump (14) from the timing gear housing. c.  Disassembly.  Disassemble the fuel injection pump in the ascending sequence of item numbers assigned to figure 3–21 while observing the following: (1) (2) (3) (4) (5) (6) (7) (8) (9) NOTE Place all parts in a pan containing clean oil. Discard all o-rings and gaskets. CAUTION Never clamp the pump in a vice without using the fixture. Failure to observe this caution could result in equipment damage. Mount the pump in holding fixture and secure. Remove three screws (1) and remove cover containing solenoid. Rotate shut-off lever (21 ) to full shutoff position; place a screwdriver between housing and linkage hook (50) and pry off shutoff cam (25). Discard shutoff cam. Partially withdraw throttle shaft assembly (26) and lift out throttle shaft lever (45), spacers and damper barrel assembly (88). Remove throttle shaft assembly and shutoff shaft assembly (24). Loosen end plate sleeve. Remove screws (63), Iockwashers (64), flat washers (65), and transfer pump and plate (66). Remove thrust plate (67). Remove the pressure regulating sleeve (55) from end plate (66). Slide off filter element (57). Remove adjusting plug (54). Shake out the regulating spring (60) and piston (61). Reverse the assembly and remove the regulating piston seal (62). 3-49
