Now both halves of the spat can be fitted to the nose
wheel and held in place with the axle bolt, then the
spat can be aligned and the hole for the machine
screw in the yoke can be marked.
Support the front of the aircraft so that the nose
wheel is off the ground and remove the front axle
and wheel.
Fit the front of the spat over the yoke and refit the
front wheel and the axle, passing the axle through
the spat, yoke and wheel as shown at right.
Lower the nose wheel back onto the ground.
Fit the rear of the spat to the front section and move the back of the spat up or down until the
whole spat sits level or slightly low at the back (the back will tend to move up as weight is
added to the aircraft), then hold the spat in that position and mark the location of the holes for
the machine screws on each side of the yoke. A completed nose wheel spat is shown below.
Support the front of the aircraft again so that the nose wheel is off the ground and remove
both spat halves along with the front axle and wheel. Leave the wheel out of the yoke for the
moment so that you will not accidentally drill through the yoke and into the tire.
Drill a 9/64” hole in each side of the yoke at the marked locations and thread to 3/32” UNF
then refit the spat and wheel again, this time fitting the short 3/32” screws into the yoke.
Lower the nose wheel back onto the ground and check that the alignment is satisfactory and
that the tire has about 5mm clearance around the bottom of the spat, then remove both halves
of the spat, set them aside for painting and refit the nose wheel.
This completes the

task.
