CLEANING, INSPECTION AND REPAIR OF NOSE GEAR OLEO.
1. Clean all parts with a suitable dry type cleaning solvent.
2. Inspect the landing gear oleo assembly component for the following:
A. Bearings and bushings for excess wear, corrosion, scratches and overall damage.
B. Retaining pins for wear and damage.
C. Lock rings for cracks, burrs, etc.
D. Cylinder and orifice tube for corrosion, scratches, nicks and excess wear.
E. Upper and lower cylinder bushings loose or turning in cylinder.
F. Orifice plate for hole restriction.
G. Fork tube for corrosion, scratches, nicks, dents and misalignment.
H. Air valve general condition.
3. Repair of the oleo is limited to smoothing out minor scratches, nicks and dents and replacement of
parts.
ASSEMBLY OF NOSE GEAR OLEO. (Refer to Figure 32-4.)
1. Ascertain that parts are cleaned and inspected.
2. To install the piston tube plug, first lubricate the tube plug and O-ring with hydraulic fluid (MIL-H-
5606) and install the O-ring on the plug. Lubricate the inside wall of the tube, insert the plug into the top of the
tube and push it to the fork end. Align the bolt holes of the fork, tube and plug, and install bolt assembly.
3. If desired, cement a cork in the hole in the bottom of the fork body to prevent dirt from entering
between the fork and tube.
4. To assemble the components of the orifice tube, insert the orifice plate into the bottom of the tube,
with the countersunk side of the orifice hole exposed. Secure the plate with the snap ring, lubricate and install
the O-ring on the upper end of the tube.
5. Insert the orifice tube up through the bottom of the cylinder. With the tube exposed through the top of
the cylinder, install the lock washer and insert roll pin through the lock washer into the piston. Install the tube
lock nut finger tight at this time.
6. The fork and tube assembly may be assembled by installing the tube components on the tube. In order
slide onto the tube, the snap ring, washer, lower bearing with outer and inner O-rings and upper bearing. Align
the lock pin holes in the upper bearing with the pin holes in the piston tube and install pins.
7. Lubricate the inner wall of the cylinder with hydraulic fluid. Carefully insert the piston tube assembly
into the bottom of the cylinder, allowing the orifice tube to guide itself into the fork tube, until the snap ring
can be installed in the annular slot at the bottom of the cylinder. Install wiper strip and slide washer into
position, and secure assembly with snap ring.
8. At the top of the cylinder, tighten (torque) the orifice tube lock nut to 500 (min.) 600 (max.) inch-
pounds.
9. Ascertain that bushings are installed in the upper and lower torque links and then install both links.
The torque link bolt assemblies should be lubricated and installed with the flat of the bolt head hex adjacent to
the milled stop on the wide end of the link. Tighten the bolts only tight enough to allow no side play in the
link, yet be free enough to rotate.
10. Ascertain that the upper and lower oleo housing bushings are installed. Install the cylinder into the
oleo housing, position spacer washer(s) over the top of the cylinder and secure with snap ring. Install spacer
washers as required to obtain .0 to .015 of an inch thrust of the cylinder within the housing.
11. At the top of the oleo housing, install on the cylinder the aligner guide bracket and steering arm. Install
cap bolts, tighten 20 to 25 inch-pounds torque and safety with MS20995C40 wire.
