1. Bearing surfaces of housing for excess wear, corrosion, scratches and overall damage.
2. Retaining ring for cracks, burrs, etc.
3. Cylinder tube for corrosion, scratches, nicks, excessive wear and misalignment.
4. Air valve for operation and general condition.

7-16. ASSEMBLY OF MAIN GEAR OLEO. (Refer to Figure 7-5.)
a. Assemble the components of the piston tube (18) on the tube by placing, in order, the retainer ring
(17), spacer ring (16) and scraper ring (15). Insert an O-ring (14) into the annular slot in the bottom of the
housing.
b. 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.
c. Ascertain that the bushings are installed in the upper and lower torque 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 cot-
ter pins. Install washers (AN960-816L) under the head of the bolt to allow a firm sliding fit between the two
links.
d. Slide the scraper and spacer rings into place and secure with the retainer ring in the annular slot in
the bottom of the housing.
e. Lubricate and install an O-ring (5) or apply a thin layer of Permatex Forma-Gasket No. 6 Sealant,
directly underneath the flange of the cylinder head (4).
On models without the groove for the O-ring, apply Permatex
Forma-Gasket No. 6 Sealant beneath the flange of the cylinder
head (4).
f. Install the hydraulic brake line.
g. If removed, install the landing gear as described in Paragraph 7-19.
h. Service the oleo strut as given in Oleo Struts, Section II.
i. 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. To eliminate side play shim washers
633l1-03 (.005) may be used as required. Maximum side play
is .005/.007. For lubrication of links, refer to Section II.
7-l7. REMOVAL OF MAIN LANDING GEAR. (Refer to Figure 74.)
