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
require no further lubrication.
31–03 Frame Fastener Torque
Check
Frame brackets and components secured with
Huckbolt® fasteners do not require a torque check,
however, they should be inspected for damage.
Frame brackets and components secured with
conventional bolts and nuts are to be checked at
initial maintenance (IM). Check the torque of frame
fasteners to offset the effects of "bedding in" (or
seating). When checking torque, tighten the nut, not
the bolt head whenever possible. This will give a true
torque reading 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 eCascadia Workshop
Manual for torque specifications.
NOTICE
Ensure that 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
•
fifth wheel legs
•
fifth wheel mountings
•
frame crossmembers and gussets
•
front frame brackets
•
front suspension spring brackets
•
high-voltage battery mounts
•
impact structure
•
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.
