Operation Instructions
5. Fifth Wheel
Non-Intended Use
1. Operating with a non-SAE compliant
kingpin, such as kingpins which
are bent, have improper size or
dimensions, are not properly secured,
or are installed on warped trailer
bolster plates.
Failure to couple with a
SAE compliant kingpin
could result in improper
coupling, allowing
tractor-trailer
separation, which, if not
avoided, could result in
death or serious injury.
2. Operating with upper coupler and
fifth wheel lube plates that do not
maintain the SAE kingpin dimensions.
Refer to SAF-HOLLAND Service Bulletin
(Document No. XL-SB004-01), available
on the internet at www.safholland.us,
for more information on fifth wheel
lube plates.
Failure to couple with a
SAE compliant kingpin
could result in improper
coupling, allowing
tractor-trailer
separation, which, if not
avoided, could result in
death or serious injury.
3. Tow-away operations which damage or
interfere with the proper operation of
the fifth wheel.
4. The attachment of lifting devices.
5. The transport of loads in excess of
rated capacity.
6. Applications other than those
recommended in the SAF-HOLLAND
Fifth Wheel Catalog & Specification
Guide (Document No. XL-FW10066SG-
en-US), available on the internet at
www.safholland.us.
Use of fifth wheel in
non-intended
applications could result
in tractor-trailer
separation which, if not
avoided, could result in
death or serious injury.
6. Coupling Preparation
1. Prior to coupling, an inspection MUST
be performed on the fifth wheel and
mounting to verify the following:
Tighten loose fasteners.
Replace missing fasteners.
Repair/replace missing, cracked or
otherwise damaged components.
Clean grease grooves if a large
amount of debris is present.

Maintenance Procedures
11. Top Plate Removal
IMPORTANT: The FW35 series fifth
wheel assembly has
replaceable pocket inserts
installed between the
fifth wheel top plate and
mounting base. When
removing the top plate,
the pocket inserts will
either remain inside of
the top plate pockets,
on top of the mounting
bracket caps, or may fall
out. Take care NOT to lose
the pocket inserts.
Failure to prevent pocket
inserts from falling out of
the top plate could cause
a potentially hazardous
situation which, if not
avoided, could result in
minor or moderate injury.
1. Remove the bracket pin retention nuts
and bolts from both sides of the fifth
wheel top plate (Figure 33).
2. Using a pry bar, pull the bracket
pins out of the fifth wheel top plate
(Figure 33).
3. Using a lifting device capable of lifting
500 lbs. (227 kg), remove the top plate
from the mounting base. Place the fifth
wheel on a flat, clean working area.
NOTE: Follow the instructions
published by the lifting device
manufacturer for proper
operation of the lifting device.

12. Fifth Wheel Lubrication
IMPORTANT: Fifth wheel lubrication
is necessary to get the
maximum service life
from the FW35 series
fifth wheel. Perform the
following procedures at
the intervals listed.
Lubricate the locking mechanism every
three (3) months or 30,000 miles.
Thoroughly clean the locking mechanism
every six (6) months or 60,000 miles.
IMPORTANT: For fifth wheels that
operate in snowy or
icy winter conditions,
lubrication should
be performed every
spring in addition to
routine lubrication (as
noted above) to ensure
optimum operation.
12.1 Proper Lubrication Method
1. Remove old grease and debris from all
fifth wheel-to-trailer contact surfaces.
Apply new water-resistant lithium-based
grease to all fifth wheel-to-trailer
contact surfaces (Figure 34).
2. Using water-resistant lithium-based
grease, lubricate (A) the yoke tips
where contact is made with the locks
and top plate casting, (B) cam profile,
(C) yoke shaft in area that slides in
and out of the top plate casting, (D)
secondary lock where contact is made
with the cam plate, (E) release handle,
and (F) lock jaws where contact is
made with the kingpin (Figure 35).
3. Using a light oil, lubricate the (G) cam
pivot point (Figure 35).

Maintenance Procedures
If equipped with air release, follow Steps
4-9 for lubrication of the air cylinder.
4. Inspect the air cylinder tube and shaft
for dents, bending, or other damage
and replace as necessary.
5. Activate the air cylinder control to
extend the piston and shaft to its full
travel length (Figure 36).
6. Clean the exposed piston shaft with
penetrating oil and a clean shop
towel. DO NOT use any abrasives on
the exposed shaft as abrasives could
damage the piston shaft.
7. De-activate the air cylinder.
8. Remove the supply air line and add two
to four (2-4) drops of air tool oil to the
cylinder through the supply fitting. Re-
install the supply air line (Figure 37).
9. Activate and de-activate the air cylinder
two to three (2-3) times to work the air
tool oil into the cylinder and onto the
piston and verify proper operation.
12.2 As-Needed Lubrication
Maintain lubrication on fifth
wheel-to-trailer contact surfaces
using a water-resistant lithium-based
grease. Clean grease grooves if a
large amount of debris is present
(Figure 38).
Clean and lubricate the locking
mechanism if operational difficulties
arise during the service life of the fifth
wheel (i.e., problems with coupling,
uncoupling, or pulling the release
handle) (Figure 39).
