8. Ensure that there are no bolts or nuts
extending below the bolster/skid
plate within 6.0" (152 mm) of the
fifth wheel travel path while coupling
(Figure 9)
.
9. The area supported by the fifth wheel
should be free of any large holes or
gouges
(Figure 9)
.
10. Any access holes that the fifth
wheel passes beneath should have
chamfered or radiused edges.
11. Check that any splits from the skid
plate to the bolster plate are welded
adequately, and that there are no
sharp edges or abrupt changes in
elevation
(Figure 10)
.
12. 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 radiused edges.
13. Ensure that any upper coupler residual
grease is free of heavy course grit.
14. 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.
15. Verify that the kingpin is NOT obstructed
by a kingpin lock or other security device.
Failure to remove the
kingpin lock prior to
coupling may result in
improper coupling which,
if not avoided, could result
in death or serious injury.
16. Inspect the kingpin for excessive wear
and damage (using HOLLAND Kingpin
Gage tool TF-0110) and inspect for
any bowing of the bolster plate.
