Purging Hydraulic System
Refer to Figure 13
52. Charge the lift system first. Extend the lift cylinders
(black handles) until the center section is fully raised.
Remove the cylinder transport locks
and install in
storage position on lift link . Raise and lower the lift
system several times to purge air from system. Watch
for leaks and retighten fittings if necessary.
53. The gang lift system (red handles), will need purged.
The wing gangs will not start to rise until the center cyl-
inders are fully extended and the master cylinders
begin to bypass oil through the rephasing ports, to the
wing cylinders. Continue to pump oil to the gang sys-
tem until the wing gang cylinders are also fully
extended. At this point, reverse the flow and raise the
gangs, retracting all cylinders. Repeat this procedure
several times until all the air is purged out of the sys-
tem.
54. You may now charge the fold system. Before charging
the front and rear fold cylinders, make sure the rod
end of the cylinders are un-pinned or un-bolted and
block is under cylinder as shown, so that when the rod
is extended, it will clear the wing fold brackets. Extend
the fold cylinders
and (green ends) completely and
then close them. Extend and retract the cylinders sev-
eral times to purge air from the system. Now the cylin-
ders may be extended far enough to be connected to
the wing fold brackets. Remove wood block and install
the 1 x 3 3/8 clevis pin (front cylinder
), 1.5 x 1.0 x.075
machine washer and 3/16 x 2 cotter pin. Hook up rear
cylinder
(Models 5317-5323 only) with the 1x 7 Gr. 8
special thread hex bolt , two on outside fold bracket)
and 1 nylock lock nut. Tighten bolt snug but be sure cyl-
inder clevis will still pivot.

55. Attach the shank assemblies
to shank mounts with
3/4 x 4 hex bolts , (top hole) 3/4 lock washers and 3/4
nuts. Install 5/8 x 4 hex bolt , 5/8 lock washer and 5/8
nut in bottom hole.
