8.15 LANDING GEAR SERVICE
The main landing gears use 6.00 x 6 wheels and the nose gear carries a
5.00 x 5 wheel. All three tires are four-ply rating, type III tires with tubes.
(Refer to paragraph 8.23).
Wheels are removed by taking off the hub cap, cotter pin, axle nut, and
the two bolts holding the brake segment in place. Mark tire and wheel for
reinstallation; then dismount by deflating the tire, removing the three
through-bolts from the wheel and separating the wheel halves.
Landing gear oleos should be serviced according to the instructions on
the units. The main oleos should be extended under normal static load until
4.50 ± .25 inches of oleo piston tube is exposed, and the nose gear should
show 3.25 ± .25 inches. Should the strut exposure be below that required, it
should be determined whether air or oil is required by first raising the air-
plane on jacks. Depress the valve core to allow air to escape from the strut
housing chamber. Remove the filler plug and slowly raise the strut to full
compression. If the strut has sufficient fluid, it will be visible up to the
bottom of the filler plug hole and will then require only proper inflation.
Should hydraulic fluid be below the bottom of the filler plug hole, fluid
should be added. Replace the plug with valve core removed; attach a clear
plastic hose to the valve stem of the filler plug and submerge the other end in
a container of hydraulic fluid. Fully compress and extend the strut several
times, thus drawing fluid from the container and expelling air from the strut
chamber. To allow fluid to enter the bottom chamber of the main gear strut
housing, the torque link assembly must be disconnected to let the strut be
extended a minimum of 10 inches (the nose gear torque links need not be
disconnected). Do not allow the strut to extend more than 12 inches. When
air bubbles cease to flow through the hose, compress the strut fully and again
check fluid level. Reinstall the valve core and filler plug, and the main gear
torque links, if disconnected.
With fluid in the strut housing at the correct level, attach a strut pump to
the air valve and with the airplane on the ground, inflate the oleo strut to the
correct height.
