IMPORTANT: Never inflate the tractor
suspension when the
kingpin is above the
throat of the fifth wheel.
Failure to avoid inflating
tractor suspension when
the fifth wheel is not
forward of the king pin,
could result in damage to
the kingpin and fifth wheel.
10. Slowly back into the trailer, engaging
kingpin in the fifth wheel.
11. Connect the air and electrical lines.
12. Raise the landing gear legs until the
pads are just above the ground.
13. Perform a pull test as an INITIAL CHECK
by locking the trailer brakes and pulling
forward with the tractor to make sure
that tractor-trailer separation does not
occur (Figure 12).
14. Set the tractor parking brake.
15. Exit the cab and visually inspect for
the following to ensure that the lock
is closed (Figure 13).
a. Nut and washer MUST be snug
against the fifth wheel casting.
b. No gap is permissible between the
trailer upper coupler plate and the
fifth wheel.
c. Fifth wheel locks MUST be closed
around the trailer kingpin with
1/4" (6.35 mm) or less gap visible
between the lock jaws.
16. If you DO NOT achieve a proper couple,
repeat the coupling procedure.
Failure to properly couple
the tractor and trailer could
result in tractor-trailer
separation while in use
which, if not avoided,
could result in death or
serious injury.
