11. Release the tractor parking brake and
slowly pull forward 12"-18" (306-457 mm)
to disengage kingpin from fifth wheel.
Fifth wheel should be between the front
edge of trailer and kingpin (Figure 19).
IMPORTANT: DO NOT drive the tractor
free of the trailer.
12. Set the tractor parking brake and place
into neutral. Completely exhaust air
from tractor suspension, ensuring that
the fifth wheel is below the contact
surface of trailer (Figure 20).
13. Visually inspect uncoupling. Make sure
the trailer is completely supported by
the landing gear.
14. Release the tractor parking brake and
slowly pull away from the trailer.
15. Apply air to the tractor air suspension
and allow suspension to return to ride
height (Figure 21).
9. Positioning Sliding
Fifth Wheels
1.
Position the tractor and trailer, in straight
alignment, on firm, level ground clear
of obstacles and persons.
2.
Set tractor and trailer parking brakes,
place tractor in neutral.
Failure to stop and properly
lock the tractor and
trailer brakes could cause
uncontrolled sliding of
fifth wheel which, if not
avoided, could result in
component damage to
tractor or trailer.
3.
Release slide locking plungers by moving
cab switch to unlock position (Figure 22).
If manual slide release equipped, pull
release lever. If plungers do not come
out, lower the landing gear to relieve
pressure on the fifth wheel. This will
allow fifth wheel to slide easier.
NOTE: Cab switch style may differ by OEM.
