Fifth Wheel Slide Adjustment
1. Position tractor and trailer in a straight line on level ground.
2. Lock the trailer brakes.
The trailer must be stopped and the trailer brakes

by uncontrolled sliding of the fifth wheel.
3. Release slide locking plungers.
4. Move cab switch to unlock position.
5. Slowly drive the tractor forward or backward to position
the fifth wheel.
6. Re-engage the slide locking plungers. Verify that plungers
have engaged by performing a tug test.
NOTE:
Retract landing gear if lowered.
7.
Do a pull test to make sure plungers are properly engaged
and locked into the slide base.
Do not operate the vehicle if the plungers are not fully
engaged (locked). Failure to properly engage plungers and
slide base may cause loss of vehicle control which, if not avoided, could result
in death or serious injury.
