Great Plains Manufacturing, Inc. Valve Bracket Refer to Figure Note: Wings may be un-folded to finish installation. Be sure pressure is off fold cylinders as hoses will need removed from valve. You may want to get a bucket to catch some of the oil when hoses are unhooked. 8. Two new /8 diameter holes will need drilled in locations shown. Null.aac: Valve Mounting, Hose & Wiring Harnesses Valve & Hose Assembly Refer to Figure 9. Attach the new fixed bypass valve in orientation shown to the valve bracket plate with the /6 x hex bolts, /6 lock washers and /6 nuts. 0. Tighten bolts to specs, See Torque Values Chart on page 8. Note: See Hydraulic Connector ID on page 7 for proper fittings installation and torque. Be sure fittings, valve and hose ends are clean before installing fittings and hoses. Do not tighten fittings until the hoses are installed so you can rotate fittings to clear other fittings and hoses.. Attach a /mjic /morb elbow and inline filter from old bypass valve to the IN port of fixed bypass valve.. Attach the /mjic /morb elbow to the other three ports on the fixed bypass valve.. Re-attach the green extend hose 7 from tractor to the IN port (with inline filter). Re-attach the green retract hose 6 from tractor T port, left side of fixed bypass valve. Reattach hose 9 running from tee, of fold cylinder base end to R port of fixed bypass valve. Re-attach hose 8 running from tee, of fold cylinder rod end to T port (right side) of fixed bypass valve.. Attach 9/6morb /fnpt fittings 0 to top ports of fixed bypass valve. Attach 000psi pressure gauge with pressure gauge decal to left, rear port of fixed bypass valve and other 000psi pressure gauge without pressure gauge decal to right, front port of fixed bypass valve. Have both pressure gauges facing towards front of machine..

Fold Assist Great Plains Manufacturing, Inc. Light Harness Front Note: The 890-9C 0 light harnesses will need removed and the new 89-7C fold assist harness and 89-87C light harness-ext lead/valve will need installed, routing the same way as the old ones were, with same hose clamps. Refer to Figure 6. Route the light harness-ext lead/valve along same path as old 0 light harness. Leave about in front of hitch on tractor plug end. Fasten light harness back to hose clamps like it was and use some plastic ties as needed. 7. Fasten conductor male weatherpack end of light harness-ext lead/valve to conductor female weatherpack end (6 lead) of fold assist harness. Attach other conductor male weatherpack (6 lead) to conductor female weatherpack end of solenoid valve on fixed bypass valve. 8. Route 0 leads of fold assist harness from center of machine under front trusses along front center brace bar to proximity sensor lead. Plug end of 0 fold assist harness into proximity sensor lead. Fasten harnesses up to center brace bar with plastic ties to keep harnesses from getting pinched when folding. Figure Light Harness Front 0 9. Remove the 88-89C operating instruction decal, clean area on which decal is placed, peel backing from the new 88-97C decal. Press firmly on surface, being careful not to cause air bubbles under decal. Light Harness Rear Refer to Figure 6 0. Route rest of light harness-ext lead/valve along same path as old 0 light harness was, back to enhanced module light harness 6 and plug together. Fasten light harness back to hose clamps like it was and use plastic ties as needed. Note: In order for the fold assist to work, the electrical connector must be hooked to the tractor. The fold assist will allow the operator to run very low, down pressure to the wings and still have ample pressure to the wings to unfold the unit after transporting to the field. If the system should fail for any reason, the unit may still be unfolded but the operator may need to close the down pressure valve, thereby increasing the unfold pressure to the wings. The operator may need to reset the pressure for field use. 6 Figure 6 Light Harness Rear 0 86-M 0/06/0
Great Plains Manufacturing, Inc. 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. 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) completely and then close them. Extend and retract the cylinders several times to purge air from the system.. Watch for leaks and retighten fittings if necessary.. Now the rod end of fold cylinders may be hooked up to wing with the x /8 usable pin,. x.0 x.07 machine washer and /6 x cotter pin. Bend cotter pin over to secure.. Make sure all bolts, See Torque Values Chart on page 8 and fittings, See Hydraulic Connector ID on page 7 are tight. Figure 7 Purging Fold System 08 0/06/0 86-M
6 Fold Assist Great Plains Manufacturing, Inc. Hydraulic Down Pressure Refer to Figure 8 Note: This setup procedure is for tractors with closed-center or pressure compensated flow hydraulic systems. Open center hydraulics not supported. Adjust down pressure valve as shown on decal (located on front of left truss). Refer to Figure 9. Engage the hydraulics (continuous flow) down. 6. From the cab, adjust the flow so the needle on the bypass gauge is in the green zone 000-00PSI. 7. At the valve, adjust the valve to set your initial down pressure (usually 00-00). Do not exceed 800 PSI. 8. If the wings run high during operation, increase pressure. If the center runs high, decrease pressure. If no pressure is needed, move valve in tractor to FLOAT position. Notice: When operating machine with the blades in angled position it is generally unnecessary to apply wing down pressure. Only in very hard ground will wing down pressure be necessary. Caution: When not operating with live down pressure the fold system must be in FLOAT position. Failure to operate in either float or active down pressure will damage the fold system. see your tractor operator s manual to set system to FLOAT position if necessary. Caution: This machine is designed for continuous hydraulic flow to the wing fold cylinders during field operations. It is for use on tractors having CLOSED CENTER hydraulics only.

Great Plains Manufacturing, Inc. 7 Hydraulic Connectors and Torque Refer to Figure 0 (a hypothetical fitting) Leave any protective caps in place until immediately prior to making a connection. NPT - National Pipe Thread Note tapered threads, no cone/flare, and no O-ring. Apply liquid pipe sealant for hydraulic applications. Do not use tape sealant, which can clog a filter and/or plug an orifice. JIC - Joint Industry Conference (SAE J) Note straight threads and the 7 cone on M fittings (or 7 flare on F fittings). Use no sealants (tape or liquid) on JIC fittings. ORB - O-Ring Boss (SAE J) Note straight threads and elastomer O-Ring 7. Prior to installation, to prevent abrasion during tightening, lubricate O-Ring with clean hydraulic fluid. Use no sealants (tape or liquid) on ORB fittings. ORB fittings that need orientation, such as the ell depicted, also have a washer 8 and jam nut 9 ( adjustable thread port stud ). Back jam nut away from washer. Thread fitting into receptacle until O-Ring contacts seat. Unscrew fitting to desired orientation. Tighten jam nut to torque specification. 9 Figure 0 Hydraulic Connector ID 8 7 8 Fittings Torque Values Dash Size Fitting N-m Ft-Lbs - -8 NPT.-.0 turns past finger tight - -0 JIC 9-0 - - -0 ORB w/jam nut -6 9- - -0 ORB straight 9-6 -9-6 9 6-8 JIC -7 8-0 -6 9 6-8 ORB w/jam nut 6- -6-6 9 6-8 ORB straight - 8- -8-6 JIC 7-7-9-8 -6 ORB w/jam nut 7-0-0-8 -6 ORB straight 7-8 7-0/06/0 86-M
