b.
Disassemble. In some cases it will be possible to replace a subassembly without complete disassembly. In
these instances, replace a subassembly by selecting the appropriate steps. Mount the fuel pump to the fuel
pump 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 the
fuel pump housing (29).
(4)
Pull the actuator (4) from the fuel pump housing (29). It may be necessary to rotate the actuator slightly
from 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). Remove
and discard the preformed packing (19).
(6)
Remove the capscrews (20, 21, and 22), lockwashers (23, 24, and 25), and washers (26, 27, and 28) and
separate the fuel pump housing (29) from the mainshaft, cover, and governor assembly (31). Remove and
discard the gasket (30).
c.
Inspect. See Figure 6-5.
CAUTION
To avoid contamination of the subassemblies, do not perform any operations Involving
drilling, filing, or machining. Do not Immerse subassemblies in solvent for cleaning. If
extensive cleaning Is necessary, replace or rebuild the sub assembly in accordance with
paragraph 6-10.
