Complete each of the three hydraulic fluid
conversion phases as follows:
PHASE 1:
NOTE
The hydraulic cart must conform to the
requirements of Chapter 29.
12.17A.1
Prepare the hydraulic cart as follows:
NOTE
If the hydraulic cart does not have dual system
hoses, do the following procedure before doing
step 2 for the hydraulic system No. 1 and before
doing step 2 for the hydraulic system No. 2.
12.17A.1.1 Drain the hydraulic cart until 50% of
the hydraulic fluid (C-002) stays in the cart. Add
hydraulic fluid (C-072) in the hydraulic cart until it
is full.
NOTE
If the hydraulic cart does not have dual system
hoses, do the following on the hydraulic system
No. 1 and then repeat the procedure on the
hydraulic system No. 2.
12.17A.2 Do the following steps on the
hydraulic system No. 1 and No. 2 and the flight
controls:
12.17A.2.1 Connect the hydraulic cart to the
hydraulic test couplings of the hydraulic system
No. 1 and No. 2 under the left sliding door of the
helicopter.
12.17A.2.2 Turn electrical power on or apply
external power to the helicopter.
12.17A.2.3 Turn the hydraulic cart on and apply
1000 PSI (6895 kPa) of pressure to both hydraulic
systems.
12.17A.2.4 Let the hydraulic cart run for 30
minutes.
12.17A.2.5 Move the collective stick, cyclic stick,
and pedals to operate all the flight control actuators
through full travel for a minimum of five cycles.
12.17A.2.6 Operate the HYDR SYS No. 1 and
HYDR SYS No. 2 switches between the On and
OFF
positions five times in approximately 2-second
intervals.
12.17A.2.7 Turn the hydraulic cart off.
12.17A.2.8
Turn the electrical power off or
disconnect external power from the helicopter.
12.17A.2.9 Disconnect the hydraulic cart from the
hydraulic test couplings of the hydraulic system No.
1 and No. 2.
12.17A.3
For the rotor brake do as follows:
12.17A.3.1 Remove the applicable doors and
panels to get access to the bleed valves of the rotor

NOTE
There is more than one type of rotor brake
assembly. Use the correct instructions.
12.17A.3.2 Bleed each bleed valve of the brake
assembly in accordance with the instructions
provided in Chapter 63, then service the master
cylinder with hydraulic fluid (C-072) (paragraph 12-
17).
12.17A.3.3 Repeat step 12.18.3.2.
12.17A.3.4 Install the previously removed doors
and panels.
