4.
Position the tractor so that the center of the fifth
wheel is in line with the trailer kingpin. The king-
pin should be in a position to enter the throat of
the locking mechanism.
NOTICE
Attempting to couple at the wrong height may
cause improper coupling, which could result in
damage to the fifth wheel or kingpin.
5.
Adjust the trailer height if required.
For a standard fifth wheel plate
, the trailer
should contact the fifth wheel approximately 4 to
8 inches (10 to 20 cm) behind the fifth wheel
pivot. See
Fig. 18.4
.
For a low-lube fifth wheel plate
, the fifth wheel
must slide freely under the trailer, and the trailer
should contact the fifth wheel at the pivot. See
Fig. 18.5
.
6.
With the fifth wheel lock opening aligned with the
trailer kingpin, back the tractor slowly toward the
trailer. After sliding under the trailer, STOP to
prevent from hitting the kingpin too hard, then
resume backing slowly until the fifth wheel locks.
On a standard fifth wheel, the fifth wheel must lift
the trailer.
On a low-lube fifth wheel, do not lift the trailer as
this may damage the fifth wheel plate.
