6-26. FUEL MANIFOLD INSTALLATION.
a.
Fuel Manifolds. See Figure 6-35.
(1)
Coat the preformed packings (26) with lubricant and position them into the center bores on the block sides
of the fuel manifold assemblies (27 and 30).
NOTE
The preformed packings (26) must stay in position in the fuel manifold assemblies (27 and 30)
center bores during installation.
(2)
Carefully position the fuel manifold assemblies (27 and 30) on the cylinder heads, aligning the preformed
packings (26) with the cylinder head fuel drillings. Secure the manifold assemblies (27 and 30) with socket
head capscrews (25).
NOTE
Coat the mating head surface of the screw heads with an anti-seize compound to aid in
removal.
(3)
Using a 1/4 inch socket and an inch-pound torque wrench, start in the center of each manifold assembly
(27 and 30) and tighten the socket had capscrews (25) to 40 to 45 pound-inches (4.5 to 5.1 newton-meters)
torque.
b.
Fuel Tubing (Left Bank and Right Bank). See Figure 6-35.
(1)
Lubricate the preformed packings (4) with petrolatum VV-P-236. Position the packings in the counterbores
of the fuel block connections (5).
(2)
Position the fuel block connections (5) to the fuel manifold assemblies (27 and 30). Install the socket head
capscrews (6) and finger tighten.
(3)
Position and finger tighten the fuel supply tubes (7) and fitting and ferrule assemblies (1) to the fuel block
connections (5 and 13).
(4)
Tighten socket head capscrews (6) to 40 to 45 pound-inches (4.5 to 5.1 newton-meters). Secure all fitting
and ferrule assemblies (1).
NOTE
See paragraph 9-43 for intake manifold installation procedures.
SECTION VIlI. ACCESSORY DRIVE
6-27. ACCESSORY DRIVE. The accessory drive is used to transmit power from the engine crankshaft to drive the fuel
pump.
a.
Remove.
(1)
Refer to paragraph 6-9 and remove fuel pump (7, Figure 6-4) from accessory drive (6).
(2)
Refer to paragraph 9-33 and remove the accessory drive pulley (7, Figure 9-59) from the shaft (9, Figure
6-36).
(3)
Remove capscrews (13, 14, and 15) and lockwashers (16) to remove accessory drive from engine front
gear housing. Remove gasket (17) and discard.
b.
Disassemble. See Figure 6-36.
(1)
Remove capscrew (1), plain washer (2), and pull half coupling (3) and coupling washer (4) from the
accessory drive shaft (9).
(2)
Remove shaft (9) and fuel pump gear (6) assembly from accessory drive housing (12). Remove
hourmeter spacer (5).
(3) Press accessory drive shaft (9) from fuel pump gear (6). Remove key (8) and thrust washer (7) from
