Cab and Bed Clearance Check
1. Measure the distance from the hitch jaws on the tow vehicle to the cab. A. Record measurement and vehicle make/model here: B. Add 22″ (the length of the Turning Point Pin Box) to recorded measurement in Step 1.A. C. Record result here:
2. Measure the trailer width. A. Record measurement here: B. Divide measurement in Step 2.A. by 2. C. Record result here:
3. Determine towing configuration. A. If the Step 1.C. result is 4″ greater than the Step 2.C. result, then the Turning Point Pin Box can be used in both configurations. B. If the Step 1.C. result is less than 4″ greater than the Step 2.C. result, then the Turning Point Pin Box can only be used in the standard configuration for conventional towing. The 90-degree turn and tow capability will not be available.
Operation
Conventional Transport
The Turning Point Pin Box can be used as standard pin box. Two 5/8″ – 11 x 2″ lockout bolts (Fig. 3A) installed
on the back of the unit prevent rotation and permit use of the pin box without the wedge installed.
When using the unit as a standard pin box, the two 5/8″ lockout bolts shall be torqued to 200 ft-lbs.

Moving Pivot Point
To provide towing with up to a 90-degree turn, the pivot point must be moved. Installation of a wedge block will lock the pin box at the tow vehicle’s hitch and move the pivot point from the vehicle’s bed to the nose of the 5th wheel (Fig. 4A). NOTE: Not all tow vehicle and trailer combinations will allow a 90-degree turn.
Fig. 4
A
It is normal for a gap to open up at the rear of the pin box. The gap appears when the pin box is loaded on a hitch and it normally remains after it is unloaded.
However, the gap should be no wider than 1/2″ to
ensure a safe operation. Utilizing the pin box with a larger gap can result in vehicle instability, vehicle
damage, serious injury and death.
NOTE: Please refer to hitch manufacturer’s instructions regarding the compatibility with the Lippert Turning Point Pin Box. Not all hitches are designed to accept a wedge block that relocates the pivot point.
Failure to consult with hitch manufacturer to verify compatibility may result in death, serious personal injury or severe product and/or property damage.
NOTE: Hitches listed below in the Wedge Glossary table may require a different wedge block. Please consult with hitch manufacturer to verify compatibility.

Remove rear lockout bolts when hitch wedge is to be installed. When removing hitch wedge, re-install rear lockout bolts to original location. Failure to install bolts correctly according to
instructions can result in vehicle instability, vehicle damage, serious injury and death.
1. Remove the two 5/8″ – 11 x 2″ lockout bolts and mounting hardware from the rear of the pin box (Fig.
3A) and store in the two bolt holes on the underside of the pin box (Fig. 5A). 2. Remove the standard wedge block from its storage location (Fig. 5B) by removing two bolts and lock
washers.
NOTE: The two bolts holding the wedge in place are identical to the 5/8″ – 11 x 2″ lockout bolts and can be
used interchangeably. NOTE: The standard wedge block is supplied with the pin box and is compatible with many different 5th
wheel hitches. Fig. 5

3. Determine the best orientation for installation of the wedge (Fig. 6 and Fig. 7). A. Dry fit the wedge into the hitch funnel (Fig. 8 and Fig. 9) to make sure of the proper orientation. B. The wedge should have contact with all parts of the funnel while providing adequate space for the kingpin receiver. C. Different hitch configurations may require a different orientation for the wedge.

5. Go to the Hitching Procedure section
and follow the instructions to connect
the trailer’s pin box to the tow vehicle’s
hitch.
NOTE: To assist with hitching, grease may
be applied to the wedge, around the

NOTE: For proper latching of the 5th wheel hitch, refer to the hitch owner’s manual. 6. Raise the trailer landing gear and drive the truck and trailer forward a few feet so the truck and trailer
are in a straight line. 7. Put the vehicle in park and apply the emergency brake. 8. Block the trailer wheels and lower the trailer landing gear so the landing gear is resting firmly on the
ground and supporting the trailer’s weight. 9. Tap the wedge firmly forward until it will no longer move. 10. Tighten both wedge bolts. NOTE: Both bolts may not be accessible while the unit is hitched. In this case, tighten the most accessible
bolt (usually the rear bolt). The bolts will later be tightened to the proper torque value. 11. Unhitch the trailer from the tow vehicle following the manufacturer’s instructions.
12. Torque the two 5/8″ – 11 x 2″ wedge bolts to 200 ft-lbs.
NOTE: A thin-walled socket may be necessary to torque the bolts. The wedge should be adjusted or checked for proper adjustment before each trip. If a different 5th wheel hitch is used after the adjustment, it is necessary to readjust the wedge for the new 5th wheel hitch.
Hitching Procedure
Failure to follow these instructions may result in death or serious injury.
1. Place blocks firmly against the front and rear of each trailer wheel to prevent possible movement either forward or backward.
2. If necessary, lower the tow vehicle’s tailgate. NOTE: Clearance of the lowered tailgate to the trailer needs to be monitored during hookups, since some
combinations of truck and trailer have little or no clearance. 3. Using the trailer landing gear, adjust trailer height per the manufacturer’s recommendation so the
bottom of the trailer’s pin box is 1/2″ to 1″ below the hitch skid plate (Fig. 11).

Failure to follow these instructions may result in the kingpin being too high and coming to rest on top of closed jaws or not completely inside the jaw. This could result in the trailer separating from
the hitch which may result in death or serious injury.
Do not attempt to hitch the trailer by using trailer jacks to lower the trailer and kingpin. This could result in the kingpin coming to rest on top of the skid plate instead of within the hitch opening, which may result in death or serious injury.
NOTE: During the hitching maneuver, the bottom of the trailer’s pin box should come into contact with the hitch skid plate ramp.
4. Open the jaw on the 5th wheel head. Refer to the manufacturer’s instructions for proper 5th wheel hitch latch operation.
5. Back the truck slowly toward the trailer until the truck’s hitch contacts the bottom of the pin box and the kingpin slides into the receiver.
NOTE: The truck and trailer must be straight and in line for the wedge to enter into the 5th wheel funnel. 6. Latch 5th wheel hitch in closed position per the instructions of the 5th wheel hitch manufacturer. 7. With the trailer wheels still blocked, make sure:
· The landing gear is resting on firm, level ground. · The landing gear fully supports the trailer’s weight. · The truck is stationary and in park with the emergency brake on. · The bottom of the pin box is resting on top of the hitch. · There is no space between the mating surfaces. NOTE: If space exists between the pin box and hitch, the trailer has not been properly hitched. Do not tow
the trailer. Instead, repeat the hitching steps 1-7 until the trailer is properly hitched.
Working between the tow vehicle and trailer can be dangerous. Failure to properly secure the tow vehicle and trailer from movement can result in serious personal injury or death and serious product damage. Make sure tow vehicle and trailer are secured from movement. Make sure all
safety precautions are followed to prevent personal injury or product damage.
8. Connect the electrical cable between the truck and trailer. 9. Connect the breakaway switch cable from the pin box to a permanent part of the truck with slack to
allow for rotation of pin box. 10. Raise the tailgate of the truck. 11. Do not tow the trailer until a Pull Test has been conducted.

Pull Test
Failure to perform a pull test may result in severe property damage, serious personal injury or death. Failure to secure tow vehicle and trailer from movement during procedure could result in severe property damage, serious personal injury or death. Make sure tow vehicle and trailer are
properly secured against movement during the procedure.
1. Make sure the trailer wheels are blocked, the trailer landing gear is resting on firm ground to support the trailer and the tow vehicle is in park with the emergency brake engaged.
2. Return to the cab of the tow vehicle, release the emergency brake and then apply the trailer brakes. 3. Slowly pull the trailer forward with the tow vehicle.
A. If the tow vehicle is properly hitched, the wheel blocks and trailer brakes should keep the truck from moving forward.
B. If the trailer is not properly hitched, the trailer will separate from the hitch and the truck will move forward while leaving the trailer behind. If this happens, repeat the Hitching Procedure.
4. After successfully performing the Pull Test, fully raise the landing gear per manufacturer’s recommendations.
5. Check and inspect all electrical circuits for proper operation, including clearance lights, turn signals and stop lights.
6. Remove and store all trailer wheel blocks.
Maintenance
1. Check all fasteners every 500 miles to ensure connections have not loosened. 2. Periodically check the torque values of all bolts, including 200 ft-lbs for wedge/pivot lock and 175 ft-lbs
for mounting bolts located between the trailer wings and the pin box. 3. Tighten loose fasteners to previously stated torque requirements. 4. Check bearing and grease once per season. If more grease is needed, add it to the bearing assembly.
Use any of the recommended brands below.

Do not mix lithium, calcium, sodium or barium complex greases. Mixing of these incompatible compounds can create a corrosive and/or toxic chemical with fumes that can result in a serious health risk if exposed to skin or lungs. When converting from one grease to another, make sure all
old grease is removed completely prior to applying new grease.
5. If the nut needs to be removed when checking the bearing, leave in the rear locking bolts to maintain engagement.
6. Re-torque the nut to 50 ft-lbs when replacing the nut and make sure to install a new cotter pin. 7. To mitigate squeaking, turn the pin box to 45 degrees and grease the plastic sections that are visible.
Utilize the same grease used to lubricate the hitch plate/pin.
