Operation Instructions
6. Inspect leading edge of trailer bol-
ster/skid plate. It must be free of any
square or sharp edges (Figure 7).
7. Make sure there are no bolts or nuts
extending below bolster/skid plate
within 152 mm (6.0”) of the fifth
wheel travel path while coupling.
8. The area supported by the fifth wheel
should be free of any large holes or
gouges (Figure 8).
9. Any access holes that the fifth wheel
passes beneath should have cham-
fered or radius edges.
10. Check that any splits from the skid
plate to bolster plate are welded
adequately, and that there are no
sharp edges or abrupt changes in
elevation (Figure 9).
11. The upper coupler should extend
adequately rearward to maintain full
contact with the fifth wheel during
tight turning. If it does not, at a
minimum, the rear edges should be
chamfered or radius edges.
12. Make sure that any upper coupler
residual grease is free of heavy course
grit.
13. Ensure that the upper coupler fifth
wheel contact surface is free of rust
and is not painted. The area should
be conditioned with a rust inhibitor
such as a light oil.
14. Verify that kingpin is not obstructed
by a kingpin lock or other security
device.
Failure to remove kingpin
lock prior to coupling may
result in improper coupling
which, if not avoided, could
result in death or serious
injury.
