ASSEMBLY
PFT Series Hydraulic Circuit
Installation
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.
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.
(See "Hydraulic Fitting Torque Specifications" on
page 4-2.)
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.

WARNING
CAUTION
PFT Series
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 Restrictor 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. Turn a 90 degree Male
JIC x Female Swivel JIC Elbow Fitting onto the Restrictor
in the rod 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.
See Figure 2-8.
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.
