Section IV. REMOVAL AND INSTALLATION OF MAJOR COMPONENTS AND AUXILIARIES
2-10. Preparation for Removal and Installation
a. The vehicle should be cleaned as thoroughly
inside and out as is advisable for the time available
and the operations to be performed. The affected
component and the adjscent area should be cleaned
in any case.
b. Remove any items of on-vehicle equipment,
armament or vehicular components which may
interfere with efficient operation, Where discon-
nection of lines will result in loss of fluid, close any
shutoff valves which may be in the system and,
where possible, have a container available to catch
fluid issuing from the lines at the disconnect
points. Open hull and engine compartment drain
valves to drain off accumulated water, fuel or oil.
If complete disassembly of the vehicle is to be
performed, pump out and/or - drain fuel tanks.
While the component is out of the vehicle, clean
the exposed hull or compartment areas thoroughly.
Do not operate hydraulic system when any
hydraulic- lines are disconnected.
c. See that all tools required are readily
available. Make sure that any spare parts which
may be required are available. Provide envelopes,
covers, tarpaulins, line plugs or other material
which may be required for protection of the vehicle
and exposed components until repairs are made.
Provide small parts containers, tags or electric
wire and terminal markers, as required.
d. Provide hoisting or lifting equipment for
heavy components and see that supports, benches
or stands are made ready to receive the com-
ponents when they are removed.
e. Sufficient personnel should be available for
the operation and they should be thoroughly
advised of their duties before work is started.
Provide all personnel with any protective equip-
ment which may be required, such as goggles,
