5. Coupling Preparation
1. For pulling trailers with standard SAE
kingpins which are in good condition
and securely mounted or locked in
position in the trailer.
2. To transport loads that are within the
maximum fifth wheel rated capacities:
55,000 lbs. Maximum Vertical Load
150,000 lbs. Maximum Drawbar Pull.
3. In on-road applications.
of off-road refers to terrain
on which a tractor-trailer
operates which is unpaved
and rough, or ungraded. Any
terrain not considered part of
the public highway system
falls under this heading.
: SAF-HOLLAND definition
Failure to couple with a
proper kingpin may
result in improper
coupling, allowing
tractor and trailer
separation, which if
not avoided, could
result in death or
serious injury.
3. The attachment of lifting devices.
4. The transport of loads in excess
of rated capacity.
5. In off-road applications.
6. Applications other than
recommended in SAF-HOLLAND
literature available on the
Internet at www.safholland.us.
4. As recommended in SAF-HOLLAND
literature available at
www.safholland.us.
1. Use with non-SAE kingpins, such as
kingpins which are bent, improper size
or dimensions, not secured to maintain
SAE configuration, or which are
installed in warped trailer bolster
plates, or upper coupler and fifth
wheel lube plates that do not
maintain the SAE kingpin dimensions.
Refer to SAF-HOLLAND Service
Bulletin XL-SB004-01(available on the
Internet at www.safholland.us) for
more information on fifth wheel lube
plates.
1. Prior to coupling you must
inspect the fifth wheel and
mounting.
• Confirm that lube plates are in
place and firmly fastened.
• Tighten loose fasteners.
• Replace missing fasteners.
• Repair/replace missing,
cracked or otherwise
damaged components.
•FW33-Inspect fifth wheel
mechanism. Lubricate dry or
rusty components
• If you have a sliding fifth
wheel, make sure both
plungers are fully engaged.
• Inspect air line connections.
2. Tow-away operations which damage
or interfere with the proper operation
of the fifth wheel.

appear closed. The movement of the
kingpin into the fifth wheel jaws will
allow a successful couple.
If either of the above conditions do
not exist, repeat Step 4.

11. 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
