Maintenance Procedures
12. Lube Plate Inspection
Thoroughly steam clean the top surface
of the fifth wheel for visual inspection.
Replace the lube plates if:
One or both lube plates is missing.
A straight edge laid across the lube
plate contacts any metal portion of the
fifth wheel surrounding the lube plates
(Figure 37)
.
Lube plates are severely chipped, worn,
cracked, gouged or bent.
20% (40 sq. in.) or more of lube plate
coating is missing from one or both
plates due to normal wear or damage.
13. Fifth Wheel Lubrication
FW31 and FW33 Series fifth wheels
are both equipped with NoLube lube
plate inserts that eliminate the need
to lubricate the fifth wheel-to-trailer
contact surfaces.
Thoroughly clean the locking
mechanism every six (6) months or
60,000 miles.
13.1 FW31 (NoLube) Series:
FW31 Series fifth wheels are equipped
with NoLube lock coating technology.
The lock components are protected
with a low-friction coating which
provides long wear life and corrosion
protection, eliminating the need for
lubrication. The locking mechanism
of a new FW31 Series fifth wheel
assembly has a thin layer of grease
applied by SAF-HOLLAND to aid the
components for an initial “break-in”
period. Grease will not adversely affect
a FW31 Series NoLube fifth wheel.
IMPORTANT:
If the FW31 Series
NoLube fifth wheel
operates in snowy or
icy winter conditions,
maintenance should be
performed every spring
to ensure optimum
operation. FW31 Series
NoLube fifth wheels that
are exposed to harsh
and dry chemicals and/
or road salt should be
steam cleaned and the
(B) cam profile, (D)
secondary lock where
contact is made with
the cam plate, and (E)
release handle should
be lubricated per
Section 13, Step 1.a.
13.2 FW33 (Low Lube) Series:
IMPORTANT:
Fifth wheel lubrication
is necessary to get the
maximum service life
from the FW33 Series
fifth wheel. Perform the
following procedures at
the intervals listed.
FW33 Series fifth wheel locking
mechanisms require periodic lubrication.
Lubricate the FW33 Series fifth wheel
locking mechanism every three (3)
months or 30,000 miles.
IMPORTANT:
If the FW33 Series
fifth wheel operates
in snowy or icy winter
conditions, lubrication
should be performed
every spring in addition
to routine lubrication (as
noted above) to ensure
optimum operation.
