D 7. Use a metal file to chamfer the edges and corners of
the aluminum landing gear so it will fit neatly in the recess
of the wheel pant. Position the wheel pant on the aluminum
landing gear. Accurately mark the location of the axle
mounting hole on the pants.
B. Use a 9/64" hex wrench to thread the socket head screw
through the wheel pant until the wheel goes in and the
socket head screw goes into the pant.
C. Adjust the tightness of the nut with hemostats or needle
nose pliers.
D 8. Drill a 11/64" hole in the wheel pant at the mark.
D 9. Insert the 8-32 x 1-1/2" socket head screw through
the wheel hub of your 2-1/4" wheel. Thread an 8-32 nut on
the socket head screw approximately 1/8".
D 11. Enlarge the axle notch to 11/64" in the landing gear.
Temporarily mount the wheel pant to the landing gear with
another 8-32 nut.
Note: When you reinstall the wheel after the wheel pant
has been painted, put masking tape on the bottom of the
pant so the screw will not scratch it.
D 12. Perform the same procedure to assemble and
mount the other wheel pant to the landing gear.
D 10. Test fit the wheel in the wheel pant using the
following procedure.
A. Insert the threaded end of the screw into the wheel pant
axle hole. The socket head of the screw will be protruding
from the pant.
D 13. Before painting the wheel pants, fill the seams and
other imperfections with filler such as Squadron White Putty,
or resin filler such as Bondo . We use Bondo most of the
time because it cures quickly and is easy to sand. Squadron
putty works well, but it takes several hours to cure.
