MAIN GEAR/WHEEL ALIGNMENT
There is no way to adjust the alignment within
each main gear wheel set. If the tires are
showing signs of abnormal/unsymmetric wear,
some component has likely been worn/bent.
Starting with the axle, examine each main gear
component and mounting point for signs of
damage/deformation. Replace damaged
components once found.
If no gear/bulkhead/airframe components are
found to be damaged, use the following
procedure to align left and right floats:
1.
Move aircraft to level surface, ensure both
nose wheels are facing aft (i.e. positioned
for forward motion)
2.
Measure the length of the forward flying
wires, from the aft face of the clevis on each
end. These distances should be equal. If
they are not, loosen the jamb nuts and adjust
the wires as required so the length of each is
equal.
3.
Tighten each forward wire until is snug, then
tighten the jamb nuts. Wire should not be
overly tight, but should be tight enough to
prevent excessive motion at the center.
4.
Next, tighten the aft wires in a similar
fashion; measuring between the face of the
clevises and loosening, then tightening the
wires until they are of equal. Secure with
jamb nuts.
BLEEDING BRAKE SYSTEM
Whenever the hydraulic brake lines are
disconnected and reattached the brake system
should be bled. To bleed the brake system:
1.
Check that all lines are properly attached
between the brake calipers and brake master
cylinders
2.
Check brake fluid reservoir level and fill to
MAX line (located on the pilot side of the
engine compartment mounted to the
firewall).
3.
Depress brakes using pilot pedals, brakes
will likely be “spongy” and need significant
travel to build braking force.
4.
Loosen hydraulic fitting at one brake caliper
just enough to let fluid and air seep out
when brakes are actuated.
5.
While one person actuates the brakes, a
second person should watch the brake
caliper with the loose fitting.
6.
If air is in the system, actuating the brakes
will cause bubbles in the fluid coming out of
the loosened brake caliper fitting.
7.
Actuate the brakes through full travel
several times until all the bubbles have been
released and fluid is being expelled at the
loose caliper without signs of air.
8.
Tighten the loose caliper fitting.
9.
Check fluid level in brake fluid reservoir
and refill to MAX line as necessary.
