8.13 BRAKE SERVICE

The brake system is filled with 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 left side of 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 6.00 x 6 wheels. All three tires are 6.00 x 6 tube
type. The main gear tires are 6 ply rating and the nose gear tire is 4 ply
rating. (See Section 8.23.)
Main wheels are removed by taking off the hub cap, axle nut, and the
two bolts holding the brake segment in place, after which the wheel slips
easily from the axle.
The nose wheel is removed by taking off the axle nut and washer from
one side, sliding out the axle rod and plugs, lightly tapping out the axle
tube, and then removing the wheel and spacer tubes from between the fork.
Wheels are replaced by reversing the procedure.
Tires are removed from the wheels by deflating the tire, removing the
through bolts, and separating the wheel halves.
Landing gear oleo struts should be checked for proper strut exposure
and visible leaks. The required extensions for the struts under normal static
load (empty weight of airplane plus full fuel and oil) are 3.25 inches for the
nose gear and 4.5 inches for the main gear. If the strut exposure is below
that required, it should be determined whether air or oil is needed 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 fluid is then visible up to the bottom of the
filler plug hole, only proper inflation with air is required.
