Step 3
With the legs in position, locate the cross
support weldment (#3). Loosely attach the
cross support between the two leg assemblies
(#1, #2) with the provided M14 hex bolts (#4),
and flat washers (#5).
Note:
For easier install the pin and head can be
removed while installing into bed of truck.
Step 4
Remove the four lynch pins securing the
locking handles to the legs. Swing all four
handles completely open and lower the legs
into position in the bed of the truck.
Ensure all four locking bolts and spacers
drop into the mounting holes before
attempting to close the handles.
Step 5
With the 5th wheel legs in position, torque all eight
M14 bolts to 100 ft-lbs. Re-install the 5th wheel
head if it was removed to ease installation.
Step 7
Confirm all four locking bolts are engaged in the truck bed mounts
and the castle nuts are secured with the cotter pins. Double check to
ensure all four handles are securely locked with the lynch pins. The
5th wheel legs are now installed and ready for use.
Step 6
With the legs secured and positioned in truck bed mounts, rotate
the handles back to the closed position. Secure the handles by re-
inserting all four lynch pins.
Note:
Slight resistance should be felt
as the handles are rotated closed. If the handle will not close with
moderate pressure, adjustments must be made to the locking T-bolt;
see 'T-bolt Adjustment'.
WARNING
Forcing the handle closed may damage the locking bolt
and handle, possibly resulting in trailer detachment.
T-Bolt Adjustment
The locking T-bolts are pre-installed to ease installation. Due
to possible variation in the truck's mounting locations, some
adjustments may be required. If one or more of the locking handles
will not close, begin adjustment by removing the cotter pin securing
the castle nut above the handle. See figure below.
Next, loosen the castle nut 1/4-turn while pressing down on the
T-bolt. Reattempt to close the locking handle. If the handle closes,
re-secure the castle nut with the removed cotter pin. If the handle
does not close, loosen the castle nut 1/4-turn while pressing down
on the T-bolt and reattempt to close the locking handle.
