Hydraulic Installation
WARNING
Escaping fluid under pressure can be nearly
invisible and have enough force to penetrate the
skin causing serious injury. Using a piece of
cardboard, rather than your hands, to search for
suspected leaks. (See Figure 2-10.) Wear
protective gloves and safety glasses or goggles
when working with hydraulic systems.
Tightening Procedure for JIC 37 degree Swivel
Female Nuts.
1. Check Fitting Flare and seat for defects.
2. Lubricate the connection.
3. Install Hydraulic Hoses without twists.
4. Hand Tighten until connections bottoms.
5. Using 2 wrenches to prevent twisting, rotate the
Swivel Nut 2 wrench flats (1/3 turn).
6. For reassembly, follow the same procedure but
tighten only 1 wrench flat (1/16 turn).
Tightening Procedure for Swivel O-Ring Fittings.
1. Lubricate O-Ring and install the Fitting until the Metal
Washer which backs up the O-Ring contacts the face
of the boss.
2. Orient the Fitting by turning counterclockwise up to 1
turn.
3. Tighten the Locknut using 50-60 ft-lbs of torque. See
"Hydraulic Fitting Torque Specifications" on
Page 5-2.

Hydraulic Assembly
1. Restrictors installed in Cylinder Ports, connect 45
Degree Fitting so they are free to swivel. Connect top
Hydraulic Hose to the Cylinder Base and bottom
Hydraulic Hose to the Cylinder Rod End. Position the
Hydraulic Hoses so that the Cylinder Base End points
downward and the Cylinder Rod End points upward.
Merge Hydraulic Hoses together and tie wrap them
together about 12 inches from the Hose End. See
Figure 2-11. Be sure that the Hoses cannot sag and
make contact with the Front Roller Wheels.
