kingpin is not entering the locks
properly.
2.
Locks are closed.
3.
Excess accumulation of rust or
grime is interferring with lock
operation.
PROBLEM: Difficult to couple to trailer
Remedy
1.
Chock trailer wheels. Then using LOW
GEAR, lower the trailer landing gear
until the bolster plate is aligned with
the fifth wheel, as shown in
Figure 3
.
2.
Make sure the locks are open. To open
locks, slide the handle forward and
pull it out to the maximum extension.
The lock will swing to the open position
(
see Figure 4
). If the lock does not open,
hold the handle all the way out and
use a pry bar to rotate the lock into the
open position. Do not put your hands
or fingers on or near the lock jaw.
3.
Thoroughly steam clean the fifth wheel
then relubricate all moving parts, as
described in Holland Service Bulletin

in the lubricant. Follow recommended
lubrication schedule as detailed in
Service Bulletin XL-SB41.
