8.13 BRAKE SERVICE
The brake system (Figure 8-1) is filled with Univis No. 40 or
MIL-H-5606 (petroleum base) hydraulic brake fluid. The fluid level should
be checked periodically or at every 50 hour inspection and replenished when
necessary. The brake reservoir is located on the fire wall in the engine
compartment. If the entire system must be refilled, fill with fluid under
pressure from the brake end of the system. This will eliminate air from the
system.
No adjustment of the brake clearances is necessary. If after extended
service brake blocks become excessively worn, they should be replaced with
new segments.
8.15 LANDING GEAR SERVICE
The landing gears use 5.00 x 5 or optional 6.00 x 6 wheel assemblies*. All
three tires are four ply rating, type III tires with tubes. (Refer to paragraph
8.23.)
CAUTION
Proper tire inflation must be maintained to
prevent high sensitivity of the nose wheel
steering during takeoffs and landings.
Wheels are removed by taking off the hub cap, cotter pin, axle nut, and
the bolts holding the brake segment in place. Mark tire and wheel for
reinstallation; then dismount by deflating the tire, removing the through-
bolts from the wheel and separating the wheel halves.
The nose gear oleo should be serviced according to the instructions on
the unit. The oleo should be extended under normal static load until 3 inches
of oleo piston tube is exposed. Should the strut exposure be below that
required, it should be determined whether air or oil is required by first raising
the airplane 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.
*6.00 x 6 wheel assemblies are standard on aircraft with serial nos.
38-81A0001 and up. Optional on earlier aircraft.
