Purging Fold Hydraulic System
Note: When the fold hoses are hooked up and tighten the fold
system will be purged of air.
Refer to Figure 7
21. Before charging the fold cylinders
, un-pin the rod
end of all cylinders and block up cylinders as shown, so
that when the rod is extended, it will clear the wing fold
brackets. Extend the fold cylinders
(green ends) com-
pletely and then close them. Extend and retract the cylin-
ders several times to purge air from the system.
22. Watch for leaks and retighten fittings if necessary.
23. Now the rod end of fold cylinders may be hooked up to
wing with the 1 x 3 1/8 usable pin , 1.5 x 1.0 x.075
machine washer and 3/16 x 2 cotter pin. Bend cotter pin
over to secure.
24. Make sure all bolts, See “Torque Values Chart” on
page 8 and fittings, See “Hydraulic Connector ID” on
page 7 are tight.
