Installation Instructions for 16K Fifth Wheel Hitch with Kwik-Slide
Part Numbers:
- 30051 (Combines 30047 and 30048)
Tools Required:
- Torque Wrench
- 1/2" Socket and Wrench
- 3/8" Socket and Wrench
- White Lithium Grease (Spray Recommended)
- Tape Measure
- Marking Pencil
Step-by-Step Instructions:
Step 1: Guidelines for Matching Tow Vehicle and Trailer
- Ensure the gross trailer weight (including cargo and water tanks) does not exceed 16,000 lbs.
- Verify the kingpin weight is between 15-25% of the trailer weight and does not exceed 4,000 lbs.
- Use a SAE 2-inch kingpin with your fifth wheel hitch.
- For short-bed trucks (6-8 ft.), ensure the trailer has an extended pin box or add a Kwik-Slide (Part # 30048) for low-speed maneuverability. Always monitor clearance to avoid truck and trailer damage during turns.
Step 2: Install Base Rails and Mounting Hardware
- Place the base rails across the truck bed as specified in the rail mounting kit instructions (Part # 30035).
- Ensure the rails are positioned parallel, with centerlines spaced 21.94 inches apart. Check diagonal measurements to verify alignment.
- Install spacers and bolt plates beneath the bed to fill corrugations.
- Attach the mounting brackets to the truck frame and torque all bolts to the specifications in the rail mounting kit instructions.
Step 3: Assemble the Fifth Wheel Hitch
- Attach the legs to the base rails, securing with long pull pins and retaining clips.
- Install the head support to the legs, adjusting the height as needed (13-17 inches) using the 1/2-13 x 4.5-inch bolts and lock nuts. Torque bolts to 75 lb.-ft..
- Lubricate the skid plate with chassis grease or use a 10-inch plastic lube plate no thicker than 3/16 inch.
Step 4: Install the Kwik-Slide Mechanism
- Grease the leaf springs on the Kwik-Slide with white lithium grease.
- Position the Kwik-Slide in the base rails, ensuring the pull pin spring clips are outside the base rail slots. This allows full sliding functionality.
- Loosely attach the hitch head support to the Kwik-Slide at the desired height, staggering the hardware.
- Install and secure the handle assembly and indicator pin on the Kwik-Slide.
Step 5: Hitching Procedure
- Block the trailer wheels on both sides.
- Adjust the trailer height with the landing gear so the bottom of the kingpin is 1/2 to 1 inch below the hitch skid plate.
- Rotate the handle latch out of the groove to open the jaws.
- Slowly back the truck so the kingpin enters the hitch. The jaws will automatically close around the kingpin.
- Verify the kingpin is seated properly with no gap between the kingpin and the hitch skid plate.
Step 6: Maneuvering with the Kwik-Slide
- Move the handle forward to unlock the Kwik-Slide.
- Use the truck to carefully slide the hitch 10 inches rearward to the maneuvering position for low-speed operations, such as backing into a tight spot.
- Perform a pull test to ensure the Kwik-Slide is securely locked in the maneuvering position.
- After maneuvering, return the hitch to the towing position by sliding it forward until the latch locks. Repeat the pull test before towing.
Step 7: Unhitching Procedure
- Block the trailer wheels and ensure the landing gear is on firm ground.
- Disconnect the power and breakaway switch cables.
- Rotate the latch to open the jaws and pull the handle fully to release the kingpin.
- Drive the truck forward slowly to separate from the trailer.
