Cylinder Installation
Install the base end 4-1/2 x 8 Rephasing Hydraulic
Cylinders to the Cylinder Anchors on the front of the LH
and RH Center Frames with the vendor supplied
hardware. Cylinder ports face up. Adjust the Anchor Nuts
to achieve a distance of approximately 7-1/2" from the
Center Frame Tube to the center of the Cylinder Pin. See
Figure 2-16.

WARNING
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 your hands, to search for
suspected leaks. Wear protective gloves & safety
glasses or goggles when working with hydraulic
systems.
The hydraulic system consists of 3 separate circuits.
Plumb the circuits in the following order:
1. Tooth Control Circuit - Black - See Figures 2-17,
2-18 and 2-19. The Tooth Control Circuit with shanks
raised requires approximately 2.3 gallons of hydraulic
oil, and with shanks lowered requires 2.6 gallons of
hydraulic oil.
2. Fold Circuit - Yellow - See Figures 2-23, 2-24 and
2-25. The Fold Circuit with wings folded, requires
approximately 6.0 gallons of hydraulic oil and with
wings unfolded, requires 7.2 gallons of hydraulic oil.
3. Lift Circuit - Blue - See Figures 2-26 and 2-27. The
Lift Circuit with machine raised, requires
approximately 4.9 gallons of hydraulic oil and with
machine lowered, requires 4.5 gallons of hydraulic oil.
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.

page 4-2.)
