Troubleshooting
Difficult to Couple to Trailer:
3
POSSIBLE CAUSE REMEDY
Attempting to couple too fast. Couple in accordance with the procedure in this
Owner’s Manual.
The trailer may be too high; the kingpin
is not entering the lock properly. Lower the trailer in accordance with
manufacturer’s instructions.
Locks are closed. If equipped with manual secondary lock, pull
secondary release handle and hook on casting.
Pull release handle all the way out. If air release
equipped, set tractor brakes and actuate fifth
wheel control valve to open locks.
Locks may be open even if they still appear
closed. Check to make sure nut and washer at
front of fifth wheel are not snug against fifth wheel
and that release handle is in extended “open”
position. If both of these conditions exist, you can
still successfully couple the fifth wheel even
though the lock jaws appear closed. The move-
ment of kingpin into fifth wheel jaws will allow a
successfully couple.
Accumulated rust or grime interfering
with the lock operation. Thoroughly clean the fifth wheel and relubricate
in accordance with the procedure in this Owner’s
Manual.
The lock is adjusted too tightly. Check lock adjustments in accordance with the
procedure in this Owner’s Manual.
The lock may be damaged. The fifth wheel M MUST be rebuilt using the
appropriate SAF-HOLLAND service kit.
Damaged, bent release handle. Replace release handle using the appropriate
SAF-HOLLAND service kit.
Damaged, bent yoke shaft from
improper coupling. The fifth wheel M MUST be rebuilt using the
appropriate SAF-HOLLAND service kit.
Bent kingpin, damaged upper coupler,
or improper use of “lube plate” may be
interfering with lock movement. Check the kingpin and upper coupler as detailed
in Holland Service Bulletin XL-SB020. Repair/
replace as required. Remove any improperly
installed or improperly specified lube plates.
Refer to Holland Service Bulletin XL-SB004-01 for
lube plate warnings.
