Wheel Pants - Carf-Models Extra 330sc Assembly Manual

Wheel Pants:

The wheel pants require two shaped milled plywood pieces to be
glued in place. The longer of the two pieces sits in the recess of the
wheel pant, you will need to chamfer the top edge to acquire a neat
fit. The shorter piece needs to be glued on the inside of the wheel
pant, this piece will hold the 6mm T nut for the axle bolt as well as the
3mm T nut to hold the wheel pant to the undercarriage leg.
Rough up the area where the shaped milled plywood pieces sit
and epoxy in place. Set aside and let cure. After the epoxy has cured,
locate the dimple in the recess at the inside outer surface of the wheel
pant. You need to drill at this point a hole large enough to accommo-
date a 6mm T-nut, a 7.5mm drill bit will do nicely.
You will notice that the 6mm T-nut protrudes well past the surface of
the wheel pant. At this point you can elect to cut down the threaded
portion of the T-nut, or simply let the T-nut stand proud inside the
wheel pant. If you elect to let the T-nut stand proud, don t forget to fill
the space between the T-nut and the ply with epoxy and micro bal-
loons (if using Hysol you will not need micro balloons).
When you have the 6mm T-nut secured in place trial fit the wheel
pant to the landing gear leg. You will need to set the angle of the
wheel pants before you drill the 3mm securing bolt.
Locate the 6mm x 70mm axle cap head axle bolt, wheel collars, 6mm
flat washers and 6mm nylock nuts. The positioning of the wheel col-
lars is shown in the picture opposite. You will now need to drill a hole
in the outer surface of the wheel pant big enough for the axle bolt to
pass through.
Assemble the wheel and axle onto the landing gear leg, ensuring that
the wheel remains able to rotate freely. Please note if you are using
Dubro wheel, you will need to drill out the axle hole to 6mm.
To set the angle of the wheel pants, level the fuse at the canopy rails.
Set the wheel pants to 65mm at the rear. You can now drill the 3mm
hole required to secure the wheel pant. When you have done this in-
sert a 3mm T-nut into place in the wheel pant.
