Install Right Cylinder Hoses
Refer to Figure 13
54. Select two hoses:
HP-9JF154
3/8" HOSE X 154" 9/16 JICF ENDS
One with orange tie or “R” tag, and one without.
55. Connect one end of the hose with the orange/R
marking to sequence valve port R.
56. Connect the unmarked hose to sequence valve
port C
57. Route the hoses under the clamp on the rear
face of the wing lock lug. Leave clamps lightly snug
at this time, to allow for sag and slack adjustment at
step 61.
58. Route the hoses under the clamp at mid-wing
near the fold cylinder rod end.
59. Route the hoses to the front of the wing, under the
adjustment valve assembly and under the outer
wing clamp
.
60. At the cylinder, connect the orange/R hose to the
elbow fitting at the rod end.
Connect the unmarked hose to the elbow at the
base end
.
61. Adjust hose sag and slack:
62. Tighten all clamps.
Null4:
• Allow just enough sag at the wing pivot so that
the hose is near, but no lower than the wing
pivot pin.
• Where the hoses naturally cross each other at
the cylinder, secure a cable tie.
• Add a second tie approximately 40cm (16in)
away, to bundle the hoses.
• Create enough slack at this location for a loop no
higher than the spring holder on the marker.
The rod end hose must follow the rod end of the
cylinder as it swings out and toward the rear dur-
ing marker extension.
• Balance remaining slack at the adjustment valves
and at the sequence valve.
Check that all slack is clear of moving parts.
