Connect Cylinders
Prepare Cylinder Ports
Refer to Figure 14
The cylinders have three ports:
• The cylinder face with a single base end port is to be
the bottom face.
• The cylinder face with both base and rod end ports is
to be the side face. Only the rod end port is used. This
port may face forward or back when installed.
Machine Damage Risk:
The cylinders must be connected using the designated two
(of three) ports, and must be installed with the base end port
down, and the rod end (side) port facing to planter front or
rear. Any other configuration will result in fitting damage
during marker use.
44. Select two new:
810-196C CYL 2.5X10X1.12 ROD (TIE)
These cylinders may be pre-installed in the mount
weldments. If so, remove the cylinders from the
mounts. Disconnect the rod end tang (not shown at
right) from the inner arm lug, if connected. Save all
pins, spacers and fasteners.
Note: If the cylinders already have elbows installed, do
not perform step 45 through step 49, but use
those steps to verify that the cylinders are setup
correctly for this installation. It may be necessary
to adjust elbows, or swap an elbow with a plug.
45. Remove any threaded plug or dust plug from the
(side) rod end ports .
46. Remove any threaded plug or dust plug from the
(bottom) base end ports .
47. Inspect the plugs at the unused (side) base end
port . If either of these ports is plugged with a dust
plug (non-threaded), replace it with a threaded plug
removed from one of the other ports. Any remaining
plugs are not re-used.
Install Cylinder Fittings
Refer to Figure 15
48. Select four new:
811-065C EL 9/16MJIC 9/16MORB
49. Remove any protective caps from the MORB ends
of the elbows. Install elbows at all open ports
(
, ) on both cylinders. Point MJIC end toward
cylinder base before tightening jam nut. See
page 20 for ORB fitting installation information. Do
not use pipe sealant.
