Tightening Procedure For JIC 37° Swivel Female
Nuts
1. Check flare and seat for defects.
2. Lubricate the connection.
3. Install hoses without twists.
4. Hand tighten until connection 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 (1/6 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 lock nut using 50-60 foot pounds torque.
Attach the Manual Storage Canister using two 4-1/2
Hose Clamps.
(See “Hydraulic Fitting Torque Specifications” on
page 4-2.)
CAUTION

You can find the components needed to assemble the
Hydraulic Circuit in either the Bridge Hitch Box Assembly
or the Pulverizer General Box Assembly.
Remove Fitting Caps prior to installing Fittings.
Screw a 90 degree Male ORB X Male JIC into the rod
end port and a 90 degree Male ORB x Female Swivel JIC
Elbow Fitting into the base end port of the Hydraulic
Cylinder. Screw a Restrictor into the Ball Valve port that
will connect up to the base end of the hydraulic cylinder
and a Male ORB X Male JIC Adapter Fitting into the other
port of the Ball Valve. Connect the Ball Valve Restrictor
to the Elbow in the base end port of the Cylinder.
Assemble Bulkhead Fittings into the bulkhead plate
located on the top of the of the Bridge Hitch Tube.
Connect 3/8 x 185 Hose Assembly to the Cylinder rod
end Elbow Fitting and 3/8 x 161 Hose Assembly to the
Ball Valve Adapter Fitting. Route hose up the Bridge
Hitch connecting them to the Bulkhead Fittings. Connect
3/8 x 150 Hose Assemblies to the bulkhead fittings and
route them along the Bridge Hitch to the Gooseneck
Coupler. Turn a 90 degree Male JIC x Female Swivel JIC
Elbow Fittings into the end of the Hoses. Assemble Male
ORB X Male JIC Adapter Fittings into Male Couplers and
turn them into Elbow Fittings at the end of the Hoses.
Secure hoses with Twin Clamps, Top Plate and 5/16-18
1-1/4 Bolts in the mounts provided on the Bridge Hitch.
Ag Harness Installation
Connect Ag Harness to the Pulverizer Light Module.
Route the Ag Harness with the Hydraulic Hoses along
the Bridge Hitch to the Gooseneck Couple. Bundle and
Secure Harness to the Hoses with Tie Straps.
Escaping fluid under pressure can be nearly
invisible and have enough force to penetrate the
skin causing serious injury. Use a piece of
cardboard, rather than hands, to search for
suspected leaks. Wear protective gloves & safety
glasses or goggles when working with hydraulic
systems.
Do not raise the machine without the use of
hydraulics. This would introduce air into the
hydraulic cylinder. When the transport pin is
removed the frame would lower rapidly possibly
causing injury.
