CAUTION
Take
necessary
precautions
to
prevent
the
entry
of
contaminants into the hydraulic system. Hydraulic lines and
ports should be capped immediately after disconnecting lines
to avoid entry of contaminants into the system.
o Whenever you open a line or fitting in the hydraulic system,
ensure it is capped.
This will help eliminate contamination
entering the hydraulic system.
o Prior to starting any maintenance procedure, ensure that you
review and have the appropriate technical manuals on hand. While
performing maintenance on the primary/backup hydraulic system on
the M992 Ammunition Carrier, use TM 9-2350-267-20. As you remove
fittings and hose assemblies from a component of the hydraulic
system, they should be tagged and placed in a safe location.
This will aid in identification of the parts when you reassemble
and install the items.

Removal, Disassembly, Assembly, and Installation of the Hydraulic
Reservoir and Filter.
Before the hydraulic reservoir can be removed from the vehicle, the right
projectile rack must be removed as outlined in TM 9-2350-267-20.
Removal of the hydraulic reservoir from the vehicle can be accomplished
using the following steps:
NOTE:
All item numbers refer to Figure 12.
o Close the suction line ball valve (1) to keep the hydraulic fluid
in the reservoir until a clean, 15-gallon container is in place
to catch it. Ensure that the container is compatible with the
hydraulic fluid.
o Disconnect the suction hose assembly (2) from the tee fitting (3)
and drain the hydraulic fluid from the reservoir (4) into the 15-
gallon container.
Place the container under the suction line
hose (2) and open the ball valve (1).
When the hydraulic
reservoir is completely empty, remove the container and dispose
of the used hydraulic fluid in accordance with local policy for
disposal of used oil.
