Refer to Figure 9.
1. Assemble elbow fittings (1) 3/8FNPT 9/16MORB on the
marker cylinder (2) ports..
2. Uncoil and attach hoses (3) 288" longs and (4) 252" long to
the swivel elbows (1). Notice that the longer hoses go to the
rod end of the cylinders.
3. Attach the 90 0 elbow fittings (5) 9-16MJIC to the sequence
valve (6). Attach the seqence valve to the mount bracket (7)
with 3/8-16 X 3 1/4 bolts (8) and 3/8-16 PLT (9) lock nuts.
4. Attach the mounting bracket with valve to the left inside the
tongue (15) as shown in Figure 10 with u-bolt (12), lock
washers (13) and nuts (14).
5. Route the hoses 3 (288") and 4 (252") from the marker cyl-
inders to the center of the drill using the same path as the
NOTE: JIC fittings do not require high torque. JIC and O-
ring fittings do not require sealant. To avoid cracking fit-
tings or castings from overtightening, do not use plastic
sealant tape.
opener lift hoses allowing the same slack at the drill toolbar
pivots as the other hoses. Use the rubber hose protectors
and hose clamp brackets which are already bolted to your
drill to secure the hoses in place. DO NOT alter the routing
or amount of hose slack of the existing hoses when you
loosen the clamp brackets to insert the marker hoses.
6. Connect the four hoses coming from the marker cylinders to
the sequence valve. Connect the base-end hoses (4) to
ports R1 and R2 (6) and the rod hoses (3) to ports C1 and
C2 (6) as shown.
7. Route hoses through the frame member cut-outs and hose
clamps parallel to the hoses feeding the outer gauge-wheel
cylinder. Route the hoses (10) 348" down the center of the
tongue tube and connect them to the elbow fittings (5).
8. Fine tune the hose placement. Make a loop in both hoses
near the box flex hinge. This loop should be large enough to
allow the outer wing to flex without the hoses pulling tight.
Maintain the loops by clamping the hoses in the center hole
of the existing hose clamps. Use the split rubber sleeves as
bushings between the clamps and the marker hose. Use the
cable ties (11) supplied with the kit to hold the hoses away
from any pinch point. Check to be sure hoses do not rub on
tires when folded in transport. This can happen if too much
slack is provided.
