MAINTENANCE MANUAL
ASSEMBLY OF MAIN GEAR OLEO. (Refer to Figure 32-1.)
1. Install the orifice assembly. if removed, by the following procedure:
A. Lubricate with hydraulic fluid (MIL-H-5606) and install an O-ring in the annular slot in the
metering orifice.
B. Insert the orifice through the opening in the top of the gear housing and turn it into the threaded
hole web. Tighten the orifice with the use of a stud type spanner wrench.
C. Lubricate and install an O-ring or apply a thin layer of Permatex Forma-Gasket No. 6 Sealant.
directly underneath the flange of the cylinder head.
D. Insert the tube of the metering assembly through the opening in the top of the housing and into
the orifice. Use caution not to cut or dislodge the O-ring slot in the orifice.
E. Secure the metering tube assembly with bolts and safety with MS20995-C32 wire.
2. Assemble the components of the piston tube on the tube by placing. in order. the retainer ring. spacer
ring and scraper ring. Insert an O-ring into the annular slot in the bottom of the housing.
3. Lubricate the wall of the piston and carefully insert it into the housing being careful not to damage or
dislocate the O-ring in the housing.
4. Ascertain that the bushings are installed in the upper and lowertorque links and then install links. At
cable end of each link. install with the use of brake line bracket. bearing washers. bolt. washer. nut and cotter
pin. Do not over tighten causing binding or damage to the link. At the connection point of the upper and lower
links, attach with the use of brake line brackets, spacer washers, grease bolt. washers. nut and cotter pins.
Install washers (AN960-816L) under the head of the bolt to allow a firm sliding fit between the two links.
5. Slide the scraper and spacer rings into place and secure with the retainer ring in the annular slot in the
bottom of the housing.
6. Install the hydraulic brake line.
7. If removed, install the landing gear. (Refer to Installation of Main Landing Gear.)
8. Service the oleo strut as given in Oleo Struts. Chapter 12.
9. Actuate the gear several times by hand to be certain it operates freely.

Links should be loose enough to allow free action of the gear, but
also resist side play. For lubrication of links, refer to Chapter 12.
10. Remote the drip pan and slowly lower the airplane from the jacks.
11. If necessary, bleed brakes. (Refer to Bleeding Brakes.)
MAIN GEAR ASSEMBLY.
REMOVAL OF MAIN GEAR ASSEMBLY. (Refer to Figure 32-2.)
1. Place the airplane on jacks. (Refer to Chapter 7.)
2. Place a drip pan under the main gear to catch spillage.
3. 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 compressingthe 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.
4. Remove the fairing from around the cylinder housing.
