1. Trim the covering from the three mounting holes in each
main landing gear cover.
❏
2. Attach each landing gear cover to the main landing
gear with three metal landing gear cover brackets, 4-40 x
3/8" machine screws, #4 washers and 4-40 nuts. Be
sure to use thread lock on the machine screws to prevent
the nuts from vibrating loose.
❏
3. Note that there is a bump (axle guide) on each side of
the wheel pant. Trim one of the molded axle guides from
each wheel pant. Important: Be sure to make a left and
right wheel pant.
❏ ❏
4. Position the wheel pant bracket on the wheel
pant, centered over the axle guide hole. Mark the two
bracket mounting holes on the wheel pant. A T-pin works
great for this. Important: The 3mm screw hole in the side
of the bracket must be towards the bottom.
❏ ❏
5. Drill a 1/8" hole at both marks on the wheel pant.
Attach the wheel pant bracket to the inside of the wheel
pant with two #4 x 1/2" sheet metal screws and #4 washers.
❏ ❏
6. Drill a 3/16" [4.7mm] hole in the bottom of the pant,
aligned with the 3mm hole in the side of the wheel pant
bracket. See the drawing in step 7.
❏ ❏
7. File a flat spot along the bottom of the landing gear
axle. Slide one wheel pant onto the landing gear axle
followed by one of the 3/16" wheel collars, a 2-1/2" wheel
and a second wheel collar. The landing gear axle should
seat in the outside axle guide. Screw a 6-32 x 1/8" set
screw into each of the wheel collars. Be sure to use thread
lock on the set screws to prevent them from vibrating loose.
❏ ❏
8. Secure the wheel pant to the landing gear with a
3mm x 3/8" machine screw threaded into the wheel pant
bracket. Again, be sure to apply thread lock to the machine
screw before tightening.
Return to step 4 and install the second wheel pant.
