Section 3 - Coupling To The Tow Vehicle
R6 3/30/2017 Page 39
A fifth wheel coupler includes a flat load-bearing
plate with a slot, and a mechanism inside the slot
that “grips” the kingpin.
Featherlite has selected a fifth wheel coupler that is
suitable for the size and weight of the trailer. You
must provide a kingpin and kingpin plate that match
the fifth wheel, and that is rated for the Gross
Vehicle Weight Rating (GVWR) of your trailer.

3.2.3.a Before Coupling the Trailer to the Tow
Vehicle
•
Be sure the size and rating of the fifth wheel
and kingpin match.
•
Wipe the kingpin clean and inspect it visually
and by feel for flat spots, cracks and pits.
Check the condition of the kingpin mounting in
the bed of the tow vehicle.
^ WARNING
A worn, bent, cracked or corroded kingpin
can fail while towing, and may result in
death or serious
Check the kingpin and kingpin plate for
wear, bending, cracks or corrosion before
coupling.
Replace worn, bent, cracked or corroded
kingpin before coupling the trailer.
•
Be sure the fifth wheel mechanism operates
freely.
•
Lubricate the fifth wheel plate surface with a
light coat of Lithium-base, waterproof grease.
•
Be sure the fifth wheel and kingpin fasteners
are tight and any welds are solid.
^ WARNING
A loose fifth wheel or kingpin can result in
uncoupling, leading to death or serious
injury.
Make sure the fifth wheel and kingpin are
tight before coupling the trailer.
•
Be sure the brake line, electrical line, and any
other lines are clear of the coupling area.
3.2.3.b Adjust Hitch Height
It is your responsibility to have the height of the
king pin or fifth wheel adjusted to match the height
of the fifth wheel or king pin in your tow vehicle.
Proper height adjustment is required to provide
clearance between the bottom of the trailer and
sides of the tow vehicle bed, to obtain level running
of the trailer and to permit equal weight distribution
on the axles. Your Featherlite dealer is able to
perform the coupler height adjustment to match the
trailer to your towing vehicle.
•
Loosen the jam nuts and set screws (A) on the
rear side. See figure 3-19.
•
Extend or retract the king pin or fifth wheel as
needed, but do not exceed 8 inches maximum
extension.
•
Tighten setscrews (A) to 75-100 lb ft of torque.
•
Tighten jam nuts to 75-100 lb/ft of torque.
•
Check tightness after 50 miles of towing.
