Assembly Instructions for 586-168A 1700TT Hydraulic Update Kit 1) Assemble the fittings in the down pressure valve

as shown. Be sure to apply thread sealant to the threads on the gauge.

2) Mount the new down pressure valve as shown at the rear of the hitch frame. Use the ½ x 4 ½ bolts w/ lock washers and nuts to secure the mounting bracket. Use the ¼ x 2 ½ bolts, flat washers, lock washers and nuts to mount the valve.

3) Apply pipe thread sealer to the adapter

(811-023C) fitting and screw it into the ½” FNPT Tee (811-855C) as shown.

4) Disconnect hose from the filter at the front of the existing valve (2). Remove the

filter and replace with a ¾ O-ring x ¾ JIC adapter (811-088C). 5) Screw the filter into adapter (811-023C) and reconnect

the hose from the tractor to the filter. Attach one end of one of the 12” hoses to the tee and connect the other end to the JIC adapter at the front of the valve body as shown. Do this for both 12” hoses.

6) Disconnect the return hose from the adapter at the

rear of the existing down pressure valve. Insert the Tee (811-073C) and reattach the hose as shown.

7) Attach the 131” hose (22) to the straight fitting at the

side of the new valve (3). Run this hose to the rear of the unit and attach to the base end of the left-hand fold cylinder as shown in the schematic.

8) Remove the tee that is between the hose attached to the base end of the right hand

fold cylinder and the hose, which comes from the existing pressure valve. Replace this tee with a straight adapter (811-430C).

9) Use the 42” hose (21) that you removed from the rear of the machine to connect the elbow (14) at the rear of the new valve (3) to the tee (17) that you inserted into the return line at the rear of the old valve (2).

10) This should complete the installation. Double check the hose routing with the

schematic and then tighten all fittings and hoses. After tightening, slowly try to fold the unit while watching for leaks. If no leaks occur, fold and unfold machine several times to purge the air from the system. You are now ready to set the down pressure. Refer to the instructional page for the proper procedure for setting the down pressure with multiple valves.

1700TT Hydraulic Update - Down Pressure Setup and Operation

Note: This setup procedure is for tractors with closed-center or pressure compensated flow hydraulic systems. For open-center hydraulic systems contact your dealer for instructions.

1. Adjust the bypass valve by turning knob (1), Figure 2, clockwise all the way in and then backing out 1 full turn.

2. On tractor, adjust flow-control valve to low side of flow rate. NOTE: The faster the flow of oil through the system the greater potential for oil heating, premature wear or tractor damage.

3. Lock the fold hydraulic lever for continuous downward oil flow.

4. Adjust pressure reducing valves knob (2 & 3) on implement so the pressure gauges reads 1200 psi each.

5. While watching pressure gauges, slowly open bypass valve, knob (1) until gauges reads around 1100 psi. Pressure might rise and then fall off as knob is opened. If pressure exceeds 1400 psi during this step, the tractor flow is too high, reduce tractor flow. Lock bypass valve knob (1) at 1100 psi.

6. Finally adjust valve knob (2) and (3) to 450-500 psi pressure setting. This is a beginning

pressure setting. Once you are in the field, these setting may need to change up or down. You should never need to run less than 300 psi or exceed 1000 psi. If you need to run that high of pressure, make sure the flow rate is turned down. Excessive flow can cause higher pressure readings.

7. In field operation, Lock the fold hydraulic lever for continuous downward oil flow. If a wing is running too high, increase pressure setting to the appropriate valve, knob (2 or 3), to level the wing. If a wing is running to deep, decrease the pressure setting with knob (2 or 3) on the appropriate wing valve. Make sure wing gauge wheels are properly set.

8. Caution: Never leave tractor valve centered when unfolded with machine in motion. Machine damage may occur when wings flex up or down.
