FLUSHING NO. 2 SYSTEM (refer to figure
)
(Cont'd)
1.Remove the return filter element (6) of No. 2 system
and replace it with a new one, (refer to para
) . In
alternative, and in order to reduce filter element
scraping, modify a new cartridge, by drilling it with
three holes of at least of 0.39 in (10 mm) each, to be
performed on the lateral cylindrical surface separated
by not less than 0.39 in (10 mm) (longitudinally) and
120° degree ( laterally). After that, clean and install on
aircraft for flushing procedure. This cartridge will be
used for the future flushing operation.
2.Connect the pressure hose and suction hose from the
hydraulic test stand (AGE NO. 00262) to No. 2 system
pressure ground sockets (3 and 4).
3.Verify that the hydraulic test stand (AGE NO. 00262)
reservoir has sufficient quantity of hydraulic fluid since
a substantial amount of fluid will be lost during
flushing.
4.Set test stand reservoir selector valve to aircraft
reservoir.
5.Regulate the test stand at flow rate of 5 gpm (19
l/min), and the pressure line at 900 psi ( 63 kg/cm²).
6.Start and operate the test stand according to the
applicable rules.
7.With hydraulic test stand (AGE NO. 00262) in
operation, drain the reservoir by opening the reservoir
drain cock (8) after cutting lock wire (7). After the
reservoir has been emptied, refill it again as per
