Fifth Wheel Instructions 273
CAUTION
A direct visual check is required to en-
sure proper coupling. Several types of
improper couplings will pass the initial
pull test. Sound is not reliable. Do not
take for granted that you are properly
coupled. Get out of the cab and look.

Failed trailer coupling
Make sure the trailer kingpin is in the jaw
slot and that the jaw is closed behind the
pin. The kingpin should not overhang the
fifth wheel or be caught in the grease
groove.
To verify that the kingpin is actually in the
fifth wheel slot and the jaw is closed, the
pin must be visually inspected from the
rear. Use a flashlight if necessary.
W9000181
Make sure the trailer bed is resting on the
top surface of the fifth wheel plate, and that
there is no visible gap between the fifth
wheel and the trailer bed plate.
Proper pick-up and coupling to a trailer
is a serious matter. A trailer that be-
comes disconnected while in motion is
extremely dangerous to other traffic and
may result in death or severe personal
injury. To ensure a positive hook-up or
coupling, the procedures above should
be followed in every case.
