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
locked to prevent damage to the tractor or trailer
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.
