The hydraulic reservoirs are mounted on
either side of the transmission. Each tank
has a sight glass to visually check fluid
level. Temperature bulbs in each tank
provide input to the respective hydraulic
display of the IIDS.
The integrated valve and filter modules are located on each side of the cabin roof.
They contain dual filters, pressure a n d return , to insure that a single source of
contamination does not spread to other system components. Both filters have RED
indicator buttons which warn of filter obstruction. When the return filter becomes
excessively obstructed a bypass valve opens. Each module incorporates two relief
valves which eliminate residual or thermal induced pressure from the systems after
shutdown. The pumps and reservoirs are coupled to the integrated modules by flexible
hoses with quick disconnect fittings which allow a standard hydraulic ground power
unit (hydraulic mule) to be attached for system maintenance checks.

Each system has two pressure sensors; a pressure switch, and a pressure transmitter.
The pressure transmitters are located in the pressure manifolds, and provide input for
the TEMP / PRESS display of the IIDS. The pressure switches are on the pressure side
of the integrated modules, and are connected to the hydraulic warning/caution display
of the IIDS. The indication illuminates when system pressure decreases below 6895
kPa (1000 psi). The indication extinguishes when system pressure increases above
8274 kPa (1200 psi).
