Installing the Hydraulic Hose
The Hydraulic Hose moves Hydraulic Fluid from the Power Unit to the Hydraulic Cylinder.
To install the Hydraulic Hose, you will need:
• The Hydraulic Hose. The Curved end attaches to a fitting on the Hydraulic Cylinder and the
Straight end attaches to a fitting on the Power Unit.
• One JIC to NPT hydraulic fitting. The JIC end attaches to the Curved end of the Hydraulic
Hose and the NPT end to the Hydraulic Cylinder.
• One JIC to ORB hydraulic fitting. The JIC end attaches to the Straight end of the Hydraulic
Hose and the ORB end to the Power Unit. Connected later in the installation.
The following drawing shows how to connect the Curved End of the Hydraulic Hose to the Hydraulic
Cylinder.
Drawing not to scale. Not all components shown. Some components exaggerated for clarity.
To install the Hydraulic Hose:
1. Find the Hydraulic Hose and the JIC-to-NPT hydraulic fitting.
2. Push the Hydraulic Hose through the Flex Tube with the Curved end going to the Hydraulic
Cylinder and the Straight end going to the Power Unit.
3. On the Hydraulic Cylinder, remove the Shipping Plug from the connector at the Piston / Pull Box
end.
4. Attach the NPT connector (of the JIC-to-NPT Fitting) to the Hydraulic Connector on the Hydraulic
Cylinder (where you just removed the Shipping Plug) and tighten it.
Leave the JIC connector pointing up; this will help keep the Hydraulic Hose up and away from
where the Lifting Cables will be installed.
5. Attach the Curved end of the Hydraulic Hose to the JIC connector that is facing up and tighten it.
6. Leave the Straight end of the Hydraulic Hose coming out of the Flex Tube; it will be connected to
the Power Unit later in the installation.
