  7. Slide the screw through the landing gear. Secure the
wheel pant to the gear using a 4-40 lock nut. Tighten
the 4-40 screw on to the locknut until the assembly is
almost tight. At this point the wheel pant should still be
able to rotate. Using pliers, hold the 4-40 nut inside
the wheel pant and rotate the 4-40 socket head screw
counterclockwise while positioning the wheel pant at the
correct angle. This will tighten the wheel pant assembly
between the two nuts.
Note: The two 4-40 nuts will hold the wheel pant in
position against the landing gear. You can apply a drop
of thin CA between the luck nut and the gear to keep it
from coming loose over time if necessary.
 8. Repeat Steps 2 through 7 for the remaining wheel.
