ENGINE BUILDUP – NO. 1 AND NO. 2 ENGINE AIR INLET INSTALLATION – continued
4.45.3. Installation
NOTE
Inboard coupling hardware (bolt/nut)
must face up to permit torque application
during installation.
a. Install air inlet (1) on engine (2). Torque cou-
pling nuts (12) and (13) alternately to 25 INCH-
POUNDS.
(1) Install new packing (3) in support (4).
(2) Position inlet (1) with support (4) in line with
anti–ice air tube (5).
(3) Insert alining pin (6) at top of fairing (1) in hole
(7) on engine (2).
(4) Open coupling (8). Place coupling (8) around
inlet flange (9) and fairing flange (10).
(5) Position coupling (8) with drain cutout (11) on
bottom.
(6) Install nut (12).
NOTE
When installing coupling assembly, tight-
en coupling nut to approximately 70 per-
cent of maximum indicated torque. Tap
around outside of coupling with a rubber
mallet to distribute band tension. Torque
nut to specified value. Do not over torque.
(7) Torque coupling nuts (12) and (13) alternately
to 25 INCH-POUNDS. Use torque wrench.
