POSSIBLE CAUSE REMEDY
The tractor may be putting pressure
against the locks. Lock the trailer brakes and back the tractor tightly
against the kingpin to relieve the pressure on the fifth
wheel lock, set the brakes, then pull the release handle.
Tractor too low. Raise tractor suspension to proper ride height.
The primary release handle is not pulled
out completely and hooked on the notch
in the casting. Pull the release handle all the way out, then lift
handle up and hook on casting.
Accumulated rust or grime interfering with
the lock operation. Thoroughly clean the fifth wheel and re-lubricate 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 release handle will not stay out or
must be held out when unlocking. The fifth wheel MUST be rebuilt using the appropriate
SAF-HOLLAND service kit.
Missing or damaged release system parts. The fifth wheel MUST be rebuilt using the appropri-
ate SAF-HOLLAND service kit.
Casting bent/damaged at throat area,
restricting movement. The entire fifth wheel top plate MUST be replaced.
Bent cover plate interfering with
lock movement. Inspect the cover plate for flatness and replace,
if necessary.
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.
NOTE: After the fifth wheel is unlocked and disengages from the kingpin, it is normal for the release handle to come
off the unlock notch of the casting and move into a “ready-to-couple” position.
