DRIVE SYSTEM
1.
Prepare system for storage as follows:
a.
Fill transmissions with oil (E254) (Task 1-54).
b.
Start engines (TM 55-1520-240-10).
c.
Set ENGINE CONDITION levers to
FLIGHT, and operate engines until
indicated temperatures are steady (TM
55-1520-240-10).
d.
Shut down engines (TM 55-1520-240-10).
Dry cleaning solvent (E161) is
combustible and toxic. It can irritate
skin and cause burns. Use only with
adequate ventilation, away from open
flame. In case of contact, immediately
flush skin or eyes with water for
at least 15 minutes. Get medical
attention for eyes.
e.
Clean drive system exterior surfaces. Use
cloths (E120) and solvent (E161). Wear
gloves (E186).
Corrosion preventive compound
(E153 or E154) is flammable and
toxic. Avoid inhaling. Use only with
adequate ventilation. Keep away
from heat, sparks, or open flame. In
case of contact, immediately flush
skin or eyes with water for at least
15 minutes. Get medical attention
for eyes.
f.
Coat exposed (unpainted) surface of drive
system. Use compound (E153 or 154). Wear
gloves (E186).
g.
Tag ENGINE CONDITION levers and mark
on tag TRANSMISSIONS PRESERVED DO
NOT OPERATE.
HYDRAULIC SYSTEM
2.
Prepare system for storage as follows:
a.
Check for leaks.
b.
Repair leaks.
c.
Fill flight control and utility hydraulic system
tanks (Tasks 1-59 thru 1-61 or 1-62).
d.
Lower air pressure in accumulators to 250
psi (Tasks 1-63 thru 1-68).
e.
Seal hydraulic line and tank vents. Use tape
(E388).
f.
Clean exposed polished surfaces of actuator
pistons. Use cloths soaked in fluid (E197).
Wipe surfaces with clean cloth. Apply coat of
hydraulic fluid (E197) to surfaces. Use cloths
(E120).
ROTARY-WING BLADES
3.
Prepare rotary-wing blades for storage as follows:
a.
Identify blade with aircraft serial number.
b.
Identify blade with its pitch housing color
band.
c.
Remove blades from aircraft (Task 5-64).
d.
Prepare blades for storage (Task 5-65).
e.
Fill shock absorbers (Task 1-58).
f.
Remove absorbers (Task 5-87).
g.
Prepare absorbers for storage (Task 5-91).
Store in aircraft.
ROTARY-WING HEAD
4.
Prepare rotary-wing heads for storage as follows:
a.
Service hub, pitch bearings, and vertical
hinge pin bearings oil tanks (Tasks 1-55 thru
1-57).
