29.3.1.4.3 Align holes and install bolts through
four mounting lugs, with thin aluminum alloy
washers under bolt heads.
29.3.1.4.4 Install nuts and aluminum alloy
washers on lower ends of two aft bolts. Secure

hydraulic system for leaks and normal operation.
29.3.1.4.8 Close pylon fairing.
29.3.2 Integrated Valve and Filter
Assemblies
The integrated valve and filter assemblies are
two independent modules. Each module
contains system relief valve, solenoid valve, and
system pressure and return filters. The filter
assemblies are equipped with visual differential
pressure indicators that warn of a clogging
condition. To facilitate inspection of both module
filters, an additional indicator is mounted on right
side nose frame. With electrical and hydraulic
systems operating, the indicator (viewed through
right nose window looking inboard) indicates
normal filtering if a green dot or all black
indication is present or a red dot or three white
sections will be present indicating a clogged
condition. Connections are provided on each
module for cylinder pressure and return lines,
pump pressure line, system return line and
pressure transmitter line. The valve and filter
assemblies are located inside the pylon support
and are accessible through a door on front of the
support. System 1 module is on front of the lift
beam and system 2 module is on left inside
pylon support below and aft of the lift beam. The
low pressure switch warns of low system
pressure by illuminating the NO.1 HYDRAULIC
and NO.2 HYDRAULIC segments located in the
caution panel.
