metal, brass, and aluminum contamination.
29.3.3.4.10 Replace the non-cleanable filter
element (12) P/N 205-076-034-003 if
contamination is found and flush the hydraulic
system.
29.3.3.5 Hydraulic Filter Assemblies -
Cleaning
MATERIALS REQUIRED
NUMBER NOMENCLATURE
C-002 or C-072 Hydraulic Fluid
C-003 Turbine
Fuel
C-304 Drycleaning Solvent
C-355 Detergent
NOTE
Refer to Chapter 12 for information on usage and
mixing of hydraulic fluid (C-002) and hydraulic fluid
(C-072).
CAUTION
CLEAN HYDRAULIC COMPONENTS WITH
DRYCLEANING SOLVENT (C-304) ONLY. DO
NOT USE ALCOHOL.
NOTE
Discard contaminated non-cleanable P/N 205-076-
034-003 filter elements
Examine filters for 'X's inscribed on the filter. If
there are three 'X's inscribed on filter element P/N
205-076-034-007, discard filter.
29.3.3.5.1 Use a suitable clean container large
enough to hold cleanable filter element (5, Figure
29-4) P/N 205-076-034-007.
29.3.3.5.2 Pour enough of one of the following
fluids to cover filter element (5): hydraulic fluid (C-
002) or hydraulic fluid (C-072), drycleaning fluid
solvent (C-304), 0.5% of detergent (C-355)
dissolved in clean warm water, or turbine fuel (C-
003).
29.3.3.5.3 Cap or plug both ends of the filter
element (5) to prevent contamination migration
into filter element.
NOTE
Discard cleanable filter element P/N 205-076-
034-007 after three cleaning events
29.3.3.5.4 Insert cleanable filter element (5)
only into container and vigorously agitate the
filter in the cleaning fluid.
29.3.3.5.5 Attach air hose with a nozzle and
rubber grommet to the filter element (5) to
prevent air from escaping.
CAUTION
USE NO MORE THAN 10 TO 15 PSI (68.95 TO
103.42 kPa) AIR PRESSURE SO AS NOT TO
DAMAGE THE FILTER ELEMENT
29.3.3.5.6 Using no more than 10 to 15 PSI
(68.95 to 103.42 kPa) air pressure, slowly
backflush the cleaning fluid through the filter
element (5) a maximum of three times until there
is no indication of contamination.
NOTE
Discard cleanable filter element P/N 205-076-
034-007 after three cleaning events.
29.3.3.5.7 Make an 'X' on bottom of filter
element (5) for each cleaning event.
29.3.3.5.8 Rinse the filter element (5) with
clean hydraulic fluid (C-002) or hydraulic fluid
(C-072) to remove traces of the cleaning fluid.
29.3.3.5.9 Dry
filter element (5) using filtered,
compressed air. If element is not going to be
installed immediately, put it in a new plastic bag
to prevent contamination.
29.3.3.5.10 Rinse filter bowl (5) with clean
hydraulic fluid (C-002) or hydraulic fluid (C-072).
