TM 55-2840-241-23
a. Preparation of Container
(1) Loosen two nuts (26, figure 3-1) and pivot
cover (31) around to expose air valve (32).
(2) Slowly loosen the air valve (31) to relieve
pressure in the container.
Personnel should stand clear of air valve
when loosening to prevent personal
injury.
(3) Remove thirty-two nuts (1) and bolts (37)
from the closure flange and remove cover assembly (2).
(4) Remove two cotter pins (8) and pins (9) and
remove engine side mounting brackets (12).
(5) Remove cotter pin (14) and slide pin assem-
bly (13) out until it disengages from the engine lower
mounting bracket (12). Remove the mounting bracket.
(6) Remove four nuts (7) washers (6), and bolts
(4) and remove engine side mounting adapters (5).
(7) Inspect the container to determine that it is
complete and serviceable. Particular attention should
be given to the mounting brackets, bolts, nuts, pins and
cotter pins in the engine suspension system. Replace
parts which show signs of wear and/or damage.
b. Installation of Engine In Container
The fuel system of all engines that are to
be placed in containers (less accident-
involved engines) will be thoroughly
drained, purged, and preserved. All dis-
connected lines will be capped or plug-
ged. Tape will not be used in lieu of caps or
plugs.
(1) Suspend the engine from a hoist in the
upright position (exhaust ducts up) using engine
assembly lift, tool No. 6796963.
(2) Remove the three turnover stand mounting
brackets and assemble three engine mounting
brackets (12, figure 3-1) on the engine using nine bolts
(10) and washers (11). Tighten bolts to 85-110 in. lbs.
and lockwire (item 10, table 2-2).
Do not use the engine turnover stand
mounting brackets in lieu of engine
mounting brackets. Brackets are not
interchangeable, damage to engine could
occur.
Avoid sharp bends when coiling the ther-
mocouple lead.
(2.1) Coil the thermocouple lead and secure it
to the top of the turbine.
(3) Lower the engine into the container until
the bottom mounting bracket (12) engages with the
bottom mounting adapter.
(4) Align the pin holes and engage pin assem-
bly (13). Secure with one cotter pin (14).
(5) Insert the two side mounting adapters (5)
through the locating holes in yoke assembly (15) and
engage with the two side mounting brackets (12).
Secure with two pins (9) and cotter pins (8).
(6) Secure the two side mounting adapters (5)
to the yoke assembly (15) with four bolts (4) washers (6)
and nuts (7). Tighten nuts (7) firmly then loosen one
complete turn.
(7) Release the engine weight from the hoist
and remove the engine assembly lift, tool No. 679696,
from the engine.
(8) Tighten four nuts (7) at the engine side
mounts to 40.50 in. lb.
(9) Tie the cloth bag, used to store the engine
mounting bolts (10) and washers (11), to desiccant bas-
ket (25) for future use.
(10) Place two bags of desiccant (item 11, table
2.2) into desiccant basket (25).
(11) Install gasket (3) on container base assem-
bly (24).
(12) Lower cover assembly (2) into place over the
engine. Engage the forward end of the cover with the
guide pin in the closure flange of base assembly (24);
then lower the aft end. Ensure that gasket (3) is prop-
erly seated.
(13) Install thirty-two bolts (37) and nuts (1) in
the closure flange. Bolts (37) shall be inserted from the
bottom side of the closure flange. Tighten nuts (1) fin-
ger tight.
(14) Tighten one nut (1) on each side of the con-
tainer at the center and at each of the four comers to
approximately 75 in. lb.
(15) Starting at the guide pin in the forward end
of the closure flange and moving in a clockwise direc-
tion, final tighten nuts (1) to 150-165 in. lb.
c. Container Pressurization.
(1) Tighten the air valve (32, figure 3-l).
(2) Using a source of filtered, dry, compressed
air, pressurize the container to the value shown in
table 3-1.
