lock washers and nuts, (#5, 3, & 4).
NOTE: The offset of the mount must be in the up-
ward direction.
The right hand mount (#10) is mounted similar to the
left mount only the u-bolt is installed in the outside
flange and the inside flange is bolted through the
coulter clamp (See Figure
2-1).
3. Install the marker valve mount (#6) under the inner
coulter clamp u-bolt of the coulter that is just to the
right of center on the coulter frame tube. Assemble
the valve (#7) to the mount with the 4-port side
downward using two 3/8" x 3/4" long bolts (#8) and
lock washers (#9).
NOTE: JIC fittings do not require high torque. JIC
and O-Ring fittings do not require sealant. Always
use liquid pipe sealant when adding or replacing
pipe thread fittings. To avoid possible danger of
cracking hydraulic fittings from over tightening, DO
NOT use plastic sealant tape.
Refer to Figure 2-2 for Installation Instructions steps 4,
5, and 6.
4. Route the hoses from each marker through the
mount and out the opening in the inside end of the
mount. Slide the cylinder and first section assembly
(#1) into the mount and manually swing the first sec-
tion into the lowered position. Bolt the flanges of the
assembly and mount together with four 5/8" x 1 3/4"
long bolts (#2), lockwashers (#3), and nuts (#4) in
each mount.
5. Route the hoses along the coulter frame tube and tie
them to the tube with the releasable cable ties (#6)
See Figure
2-2.
NOTE: If your hitch is equipped with the fertilizer op-
tion, the hydraulic hose can be ran with the fertilizer
hoses.
Connect the hoses to the sequence valve (#7) with
four JIC elbows (#5). Note the port markings and re-
fer to the drawing below for proper connections.
6. Connect the two 156" long hoses (#8) to the two top
ports of the sequence valve with two elbows (#5)
and route them to the tongue and through the hose
loop. Use releasable cable ties to secure hose to
frame.
