Installation. - Cont'd . Refer to figure 2-62.
h.
Inspect all connections to verify correct installation of flanges coupling gaskets, and clamps and security of cam-
lock devices.
3-21 Assemble and Install Transfer Hose Assembly, Valves and Fittings .
One (1) system par fuel unit/three (3) per TPT.
Assemblies of the transfer hose set are crated in a partially assembled condition to facilitate packaging and shipping.
Some assembly is required to place the cross and Y units in -operating condition prior to installation.
3-21.1 Assembly. Refer to figure 2-38.
a.
Position crates containing 6-inch cross and Y assemblies near their respective installation sites as indicated in
figure 2-63A.
b.
Remove 6-inch aluminum cross assembly (3) 6-inch aluminum Y assemblies (2) and coupling gaskets from
crates.
c.
Inspect all items for damage, cleanliness, and quantities required.
d.
Remove coupling clamps(3, figure 2-38)connecting flanged adapter(l)to cross (10).
e.
Slide one coupling gasket over each cross (10) flange.
f.
Align mating surfaces of adapter (1) and cross (10). Pull coupling gasket over sealing surfaces of both pieces.
Ensure gasket is correctly positioned over full circumference of sealing surfaces. Position coupling clamp (3) over
gasket.
g.
While maintaining alignment of mating parts, lock coupling clamp securely.
h.
Repeat steps e. thru g. for remaining adapters(1).
i.
Remove coupling clamps (2, figure 2-39) connecting flanged adapters (3) to Y fitting (I).
j.
Slide one 6-inch coupling gasket over each Y (1) flange.
k.
Align mating surfaces of adapter (3) and Y fitting (1). Pull coupling gasket over sealing surfaces of both pieces.
Ensure gasket is correctly positioned over full circumference of sealing surfaces Position coupling clamp (2) over gasket
I.
While maintaining alignment of mating parts, lock coupling damp securely.
m.
Repeat steps j. thru I. for other branch of Y fitting.
