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.
