(2) Remove tube assembly (1) from ECU per para 3.9.11.
(3) Remove connector (2) from hydraulic reservoir (3) and plug openings. Remove and discard
O-ring (5) from connector (2).
(4) Disconnect tube assembly (6) from elbow (7) on filter assembly (8) and plug openings. Remove
and discard O-ring (9) from elbow (7).
(5) Remove elbow (7) from filter assembly (8) and plug opening. Remove and discard O-ring (10).
(6) Disconnect tube assemblies (11 and 12) from tee (13) on elbow (14) and plug openings. Remove
and discard O-rings (15 and 16) from tee (13).
(7) Remove tee (13) from elbow (14) on hydraulic reservoir (3). Remove and discard O-ring (17) from
elbow (14).
(8) Remove elbow (14) from hydraulic reservoir (3) and plug opening.
(9) Disconnect tube assembly (18) from elbow (19) on hydraulic reservoir (3) and plug openings.
Remove and discard O-ring (20) from elbow (19).
(10) Remove elbow (19) from hydraulic reservoir (3) and plug opening.
(11) Tag and disconnect leads (21) from differential pressure switch (22) on filter assembly (8).
(12) Disconnect electrical connector (23) from thermal immersion switch (52) in hydraulic reservoir
(3).
Ensure three electro-optical sensors are removed before removal of hydraulic reservoir from
ECU enclosure. Electro-optical sensors may break off during removal of hydraulic reservoir.
(13) Tag and disconnect leads (24) on three electro-optical sensors (25) on hydraulic reservoir (3).
Remove three electro-optical sensors (25) from hydraulic reservoir (3) and plug openings.
(14) Remove fourteen screws (26), fourteen lockwashers (27) and fourteen flat washers (28) securing
hydraulic reservoir (3) to ECU enclosure. Discard fourteen lockwashers (27).
(15) Remove four screws (29), four lockwashers (30) and four flat washers (31) securing hydraulic
reservoir (3) and four shims (32) to bottom of ECU enclosure. Discard four lockwashers (30).
The reservoir assembly is heavy. To prevent injury to personnel, two people are required to
remove or install it in ECU.
(16) Remove hydraulic reservoir (3) from ECU enclosure. Ensure electro-optical sensors (25) are
removed before removing reservoir.
b. Disassembly (Refer to Figure 3-25)
(1) Remove differential pressure switch (22) from elbow (33).
(2)
Remove elbow (33) from adapter (34).
(3)
Remove adapter (34) from filter assembly (8) and plug opening. Remove and discard O-ring (35)
from adapter (34).
(4)
