SLIDING FIFTH WHEEL CONTROL (Continued)
This control is located in cab on a bracket fastened to the rear of the trans-
mission range selector. With the trailer king pin locked into the fifth wheel
jaws, inter-vehicular connections made, and trailer landing gear UP, set the
control lever to the UNLOCK position, apply the trailer brake hand control
and drive vehicle forward to slide fifth wheel and trailer king pin toward the
rear. A total 12-inches of travel fore and aft is available. Normal position of the
fifth wheel is at a point on the centerline of the rear tandem axles (See
CAUTION decal and NORMAL location arrows on both sides of the fifth
wheel assembly). The sliding feature allows adjustment of trailer and cargo
weight (when scales are available), within vehicle capacity, to prevent over-
loading of the tractor and trailer axles. Each time the fifth wheel position is
adjusted and before normal operation, the control must be moved to the LOCK
position to prevent unintentional fifth wheel and trailer movement fore and
aft.
