MAIN GEAR
1. Main Gear Oleo (See Figure 1.)
A. Disassembly
The main gear axle and piston tube assembly may be removed from the cylinder housing with the
gear removed from or installed on the airplane. On some airplanes the metering components of the
gear that are located in the top of the housing may be removed, but only with the gear removed
from the airplane. (See Main Gear Assembly - Removal, below.)
(1) Place the airplane on jacks. (Refer to 7-10-00.)
(2) Place a drip pan under the main gear to catch spillage.
(3) The gear axle and piston tube assembly may be removed by the following procedure:
(a) 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, 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 a siphon hose and drain fluid from the upper area
of the housing.
(b) Disconnect the flexible brake line at the elbow on the brake assembly.
(c) Disconnect the torque link assembly by removing any one of the three cotter pins,
nuts,washers and bolts. Note arrangement of the components for reinstallation. Carefully
slide the piston tube from the cylinder housing.
(d) The scraper ring located inside the lower end of the cylinder housing may be removed by
first removing the retainer ring, spacer ring and then the scraper ring.
(e) The O-ring seal located just before the scraper ring may be removed by using a curved
wire or spoon shaped tool and inserting it under the ring.
(4) The cylinder head and the orifice assembly, may be removed by the following procedure:
(a) Cut safety wire and remove the bolts that secure the cylinder head in the top of the
housing. Remove the assembly from the housing.
(b) Lubricate and install an O-ring on the cylinder head assembly.
(c) The orifice assembly may be removed from within the housing by rotating it
counterclockwise out of the housing with the use of a .50x .125 stud type spanner
wrench. (Refer to Chapter 95.) Do not remove orifice unless it necessitates replacement.
B. Cleaning, Inspection, and Repair
(1) Clean all parts with a suitable dry type cleaning solvent.
(2) Inspect the landing gear oleo components for the following:
(a) Bearing surfaces of housing for excess wear, corrosion, scratches and overall damage.
(b) Retaining ring for cracks, burrs, etc.
(c) Cylinder tube for corrosion, scratches, nicks, excessive wear and misalignment.
(d) Air valve for operation and general condition.
(e) Orifice plate for hole restriction.
(3) Repair of the oleo is limited to smoothing out minor scratches, nicks and dents, and
replacement of parts.
