9. Most 2-1/2" wheels (not included) are made to fit
5/32" axles, but the 8-32 screws supplied in this kit for the
axles require a larger hole. If the wheel does not roll freely
on the 8-32 x 1-1/2" SHCS "axle," enlarge the wheel hub
with an 11/64" (#18 for perfection) drill.
❏ ❏
10. Test fit the wheel in the wheel pant using the
following procedure:
A. Install an axle in a wheel. Thread an 8-32 nut about 1/8"
onto the axle.
B. Insert the wheel in the pant with the end of the screw
inserted in the plywood wheel pant mount and the head of
the screw sticking out of the wheel pant. 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.
C. Use a 9/64" hex wrench to screw the axle through the
wheel and the wheel pant until the wheel goes all the way
in and the axle goes through the pant mount.
D. Adjust the tightness of the nut with hemostats or needle
nose pliers.
❏ ❏
11. Temporarily mount the wheel pant to the landing
gear with another 8-32 nut on the axle.
❏
12. Repeat steps 1 to 11 to assemble and temporarily
mount the other wheel pant to the landing gear.
❏
13. Before painting the wheel pants, fill the seams with
putty filler such as Squadron White Putty or resin filler such
as Bondo. We use Bondo most of the time as it cures
quickly and is easy to sand, but usually it must be
purchased in large quantities. Squadron putty works well
but it takes overnight to dry and usually requires at least
two applications because it shrinks as it dries.
❏
14. After the filler has cured, wet sand the wheel pants
with 400-grit sandpaper to prepare them for primer.
