3.12.4 Fill Hydraulic Reservoir.
This task covers:
System power off. Power panel and rear control
ECV parking brake set.
Hydraulic Fluid (Item 4, Appendix D)
ECU work platform installed (see para 3.12.1).
Wiping Rags (Item 7, Appendix D)
Release latch (1) and open panel (2).
Inspect fluid level on gage (3).
Release six latches (4) and remove front top passenger side ECU cover (5).
Unscrew and remove filler cap (6) from hydraulic reservoir (8).
Rotate filter element (7) counterclockwise and remove from hydraulic reservoir (8).
Do not mix or substitute any other hydraulic fluid with MIL-H-5606.
When filling the hydraulic reservoir, do not fill past the appropriate mark: COLD when
system has not been running or has been running for less than 20 minutes; HOT when
system has been running for more than 20 minutes. If hydraulic fluid is past the COLD mark
when system has not been running, hydraulic fluid can overflow through the hydraulic
reservoir filler cap.
When required, add just enough fluid to reach the mid-point on the gage. Start the system
and let it reach operating temperature, then shut it off and check again. At 0F and above,
fluid can be checked before starting.
Add hydraulic fluid per note above.
