Steps to Verify Purchase of Proper Replacement Model
1. Look for the white sticker with a four-digit number on it, e.g. 1621 or 1716.
2. Determine the gross vehicle weight rating (GVWR) of the trailer.
3. Visually compare illustrations to the mounting wing on the 5th Wheel.
4. Measure length of box: Front row of bolts to center of kingpin (Fig.1 Dimension E).

5. Measure bolt pattern: (Fig.1 All three dimensions of A, B and C if needed).
6. Measure box width: (Fig.1 Dimension G).
NOTE: Write in the measurements of the pin box in the Actual Dimensions area of the chart.

5. Verify distance from the bottom of the kingpin plate to a flat surface is within +/- ½" of the factory setting (Fig.2A).
6. Utilizing the hardware in the pin box kit, install the bolts, washers, lock washers and nuts.
7. Torque the bolts to according to required values. Possible torque values may include: 110 ft-lbs minimum for
1/2" bolts; 160 ft-lbs minimum for 5/8" bolts; and 210 ft-lbs minimum for 3/4" bolts.
NOTE: Reference pin box installation manual to confirm specific torque values. Some models require different torque values for the bolts.
8. Reconnect the previously-disconnected electrical cables between the tow vehicle and the trailer.

Operation
Hitching Procedure NOTE: To assist with the hitching procedure, grease may be applied around the kingpin and on the skid plate surface. See the Maintenance section for recommended grease specifications.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN DEATH OR SERIOUS INJURY.
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.
1. Place chocks 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. Some combinations of tow vehicle and trailer have little or no available clearance.

3. Using the trailer landing gear, adjust trailer height per the manufacturer's recommendation so the bottom of the
trailer's pin box (Fig.6A) is 1/2" to 1" below the top portion
hitch skid plate (Fig.6B).
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 tow vehicle slowly toward the trailer until the tow vehicle's hitch contacts the bottom of the pin box and the kingpin slides into the receiver.
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:
A. The landing gear is resting on firm, level ground.
B. The landing gear fully supports the trailer's weight.
C. The tow vehicle is stationary and in park with the emergency brake on.
D. The bottom of the pin box is resting on top of the hitch.
E. There is no space between the mating surfaces.
8. 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.
B

DO NOT ATTEMPT TO HITCH THE TRAILER BY USING TRAILER JACKS TO LOWER THE TRAILER AND KINGPIN ONTO THE HITCH OPENING. 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.

9. Connect any electrical cables between the tow vehicle and trailer.
10. Raise the tailgate of the truck.
11. Do not tow the trailer until a Pull Test has been conducted. Go to the Pull Test section.
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 chocks.

Troubleshooting

What is happening? Why?

What should be done?

Trailer not level.

Adjustment Adjust pin box or hitch

needed

accordingly.

Excessive bottoming of skid pad assembly. Chucking in tow vehicle.

Operational, mechanical issues

Inspect the rubber compression bumpers to make sure they are in place. Check the trailer brakes for proper operation.
NOTE: If the above items are satisfactory, it may be necessary to install a shear spring with a different spring rate.

Skid pad assembly does not return to neutral position when disconnected from the tow vehicle.

Spring loose or damaged

Check for loose or torn rubber shear spring.

Excessive noise from pin box area.

Attachment or hitch issues

Verify that the pin box is securely attached to the 5th Wheel. If the kingpin is excessively worn, the skid pad will need to be replaced.
Hitch mechanisms can also cause noise. Verify that unwanted noise is not coming from the hitch. The hitch manufacturer can provide guidelines for this check.

Maintenance
1. Annually inspect kingpin for excessive wear.
2. Inspect the skid pad to ensure a neutral (centered) position. When the trailer is disconnected from the tow
vehicle, an equal gap of approximately 1 1/4" should be
observed between the lip of the skid pad and the rubber compression bumpers. It is normal to be able to slightly move and twist the skid pad assembly with hand force.
3. Inspect the retainment rods for excessive wear. The retainment rods may show surface scratch marks as an indication of occasional contact, but the scratches, if present, should be minimal.
4. Inspect the plastic glide pads for excessive wear. The
glide pad thickness should be no less than 3/4".
5. Periodically check the torque values of all bolts.
6. 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.

Notes

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.
