c. If desired, remove the air from the oleo chamber by depressing the air valve core pin found in the
inspection hole on top of the wing. After the pressure in the oleo chamber has diminished, remove the valve
core pin and attach a small hose to the air valve and drain the fluid by slowly compressing the piston tube. If it
is desirable to extract more fluid from the chamber, remove the filler plug, insert the siphon hose and drain
fluid from the upper area of the housing.
d. Remove the fairing from around the cylinder housing and the access plate located on the bottom of
the wing and to the rear of the housing by removing attaching screws.
e. Unhook the hydraulic brake line inside the wing assembly. This is accessible through the access
plate. Cap the line by use of a threaded cap or wrapping with plastic.
f. Remove the top four bolts by holding them with a slotted screwdriver and turning the nut with the
appropriate wrench. Remove the remaining six by use of a wrench. Carefully remove the gear assembly from
the wing.
7-18. CLEANING, INSPECTION AND REPAIR OF MAIN LANDING GEAR.
a. Clean all parts with a suitable dry type cleaning solvent.
b . Inspect the gear components for excessive wear, corrosion and damage. Check the cylinder
h o u sing and torque links for cracks, nicks and misalignment.
c. Repair of the landing gear is limited to reconditioning of parts, replacement of parts, smoothing
out minor nicks and scratches and repainting areas where paint has chipped or peeled.
7-19. INSTALLATION OF MAIN LANDING GEAR. (Refer to Figure 7-6.)
a. The main landing gear assembly may be installed on the wing by the following procedure:
1. Position the gear up in the wing through the access opening and secure with bolts, washers and
nuts.
2. Reconnect the brake line at the point of disconnection.

metal screws. Slide fairing up on the gear until wheel is removed.
c. Remove wheel by the following procedure:
1. Remove the nut and washer from one end of the axle rod and slide out the rod and axle plugs.
2. Lightly tap the axle tube out from the center of the wheel assembly by use of an object of near
equal diameter.
Be certain not to damage the axle tube end in any way. This
will make removal and installation extremely difficult.
3. Remove the spacer tubes and the wheel assembly.
d. The wheel halves (7 and 10) may be separated by first deflating the tire. With the tire sufficiently
deflated, remove the wheel through bolts (18). Pull the wheel halves from the tire by removing the wheel half
