In some cases it will be possible to replace a subassembly without complete disassembly. Inthese instances, replace a subassembly by selecting the appropriate steps. Mount the fuel pump to the fuelpump mounting plate 3375133, install it in ball joint vise ST-302, and disassemble as follows:(1)Remove all tamper proof seals and wires, and remove the capscrews (7, Figure 6-5), lockwashers (8),washers (9), and remove the damper assembly (10) and packing (11). Discard the packing.(2)Remove the capscrews (12) and lockwashers (13) and remove the gear pump assembly (14), and gasket(15). Discard the gasket.(3)Remove the capscrews (1, Figure 6-5), lockwashers (2), and washers (3) securing the actuator (4) to thefuel pump housing (29).(4)Pull the actuator (4) from the fuel pump housing (29). It may be necessary to rotate the actuator slightlyfrom side to side to aid in removal. Discard the preformed packings (6).(5)Remove the capscrews (16) and lockwashers (17) and remove the shutoff valve assembly (18). Removeand discard the preformed packing (19).(6)Remove the capscrews (20, 21, and 22), lockwashers (23, 24, and 25), and washers (26, 27, and 28) andseparate the fuel pump housing (29) from the mainshaft, cover, and governor assembly (31). Remove anddiscard the gasket (30).c.Inspect. See Figure 6-5.CAUTIONTo avoid contamination of the subassemblies, do not perform any operations Involvingdrilling, filing, or machining. Do not Immerse subassemblies in solvent for cleaning. Ifextensive cleaning Is necessary, replace or rebuild the sub assembly in accordance withparagraph 6-10.6-9
