INFLATING OLEO STRUTS: After making certain that the oleo strut has sufficient fluid, attach a
strut pump to the air valve and inflate the oleo strut. The strut should be inflated until the correct inches of
p i ston is exposed with normal static load (empty weight of airplane plus full fuel and oil on the gears. (Refer
to Paragraph 2-34.) Rock the airplane several times to ascertain that the gear settles back to the correct strut
p o s ition. (If a strut pump is not available, the airplane may be raised and line pressure from a high pressure air
system used. Lower the airplane and while rocking it, let air from the valve bring the strut down to the proper
extension.) Before capping the valve, check for valve core leakage.

BRAKE SYSTEM.
2-39.
S E RVICING BRAKE SYSTEM: The brake system incorporates a hydraulic fluid reservoir through
which the brake system is periodically serviced. Fluid is drawn from the reservoir by the brake cylinders to
maintain the volume of fluid required for maximum braking efficiency. Spongy brake pedal action is often an
indication that the brake fluid reservoir is running low on fluid. Instructions for filling the reservoir are given in
Paragraph 2-40. When found necessary to accomplish repairs to any of the brake system components, or to bleed
the system, these instructions may be found in Section VII.
2-40.
FILLING BRAKE CYLINDER RESERVOIR: The brake cylinder reservoir should be filled to the level
marked on reservoir, with the fluid specified in Table II-I. The reservoir, located on the left side of the fire wall
in the engine compartment, should be checked at every 50-hour inspection and replenished as necessary. No
adjustment of the brakes is necessary, though they should be checked periodically per instructions given in
Section VII.
2-41.
DRAINING BRAKE SYSTEM: To drain the brake system, connect a hose to the bleeder fitting on the
bottom of the cylinder and place the other end of the line in a suitable container. Open the bleeder and slowly
pump the hand brake lever and the desired brake pedal until fluid ceases to flow. To clean the brake system,
flush with denatured alcohol.
2-42.
TIRES.
2-43.
S E RVICING TIRES: The tires should be maintained at the pressure specified in Table II-I. When
checking tire pressure, examine the tires for wear, cuts, bruises and slippage on the wheel. The tire, tube, and
wheel shall be properly balanced when installed by aligning the red dot on the tire with the silver arrow on the
tube.
2-44.
POWER PLANT.
2-45.
SERVICING POWER PLANT: Regularly check the engine compartment for oil and fuel leaks, chafing
of lines, loose wires and tightness of all parts. For cleaning of the engine compartment, refer to Paragraph 2-23.
Maintenance instructions for the power plant may be found in Section VIII of this manual and in the appropriate
manufacturer's manuals.
2-46.
INDUCTION AIR FILTER.
2-47.
REMOVAL OF AIR FILTER: The induction air filter is located on the right side and midway in the
engine compartment, and may be removed by the following procedure:
a. Open the cowling on the right side of the engine.
b. Loosen the four quarter turn fasteners and separate the filter housing.
c. Remove the filter element from its screen housing by removing the four screws.
