Jost
Lubricate the kingpin lock using a hand pump grease
gun through the grease zerk on the skirt of the fifth
wheel; see
Fig. 5 . Apply a light oil to all moving
parts. For sliding fifth wheels spray diesel fuel on the
slide path of the base plate.
NOTICE
Do not use a power grease gun. The pressure will
damage the lube line.
If the fifth wheel is not equipped with low-lube plates,
apply a lithium-based grease with extreme pressure
(EP) additive to the trailer contact surface of the fifth
wheel.
NOTE: If the fifth wheel is equipped with low-lube
plates, the top plate only requires lubrication at the
new product break-in stage. The low-lube plates re-
quire no further lubrication.
31–03 Frame Fastener Torque
Check
Frame brackets and components secured with Huck-
bolt® fasteners do not require a torque check, how-
ever, they should be inspected for damage. Frame
brackets and components secured with conventional
bolts and nuts are to be checked at Initial Mainte-
nance (IM). Check the torque of frame fasteners to
offset the effects of "bedding in" (or seating). When
checking torque, torque the nut, not the bolt head
whenever possible. This will give a true torque read-
ing by eliminating bolt-body friction. When checking
the torque of frame fasteners, inspect the frame for
cracks and other damage. Set a click-type torque
wrench to the maximum torque of the fastener you
are checking. Apply pressure until the torque wrench
clicks. Do not loosen the bolt to check the torque.
See
Group 00 in the vehicle workshop manual for
torque specifications.
NOTICE
Make sure frame fasteners are properly tightened.
Continued vehicle operation with loose fasteners
could result in bracket or frame damage.
Check the fasteners at the following locations:
•
axle stops
•
deck plates
•
equalizer brackets
•
exhaust brackets
•
fifth wheel legs
•
fifth wheel mountings
•
frame crossmembers and gussets
•
front frame brackets
•
front suspension spring brackets
•
fuel tank brackets
•
radius rods
•
rear suspension spring brackets
•
shock absorbers
•
all other suspension fasteners
•
all other axle fasteners
•
all other frame fasteners
Any component that shows signs of cracking or other
damage must be repaired or replaced. Refer to the
vehicle workshop manual for repair or replacement
information.
