d. Check the general condition of each limit switch and its actuator, and wiring for fraying, poor
connections or conditions that may lead to failures.
e. Check the side brace link through center travel by attaching the upper and lower links, setting them on
a surface table and ascertaining that when the stop surfaces of the two links touch, linkage is not less
than .062 nor more than .125 of an inch through center. Should the distance exceed the required
through center travel and bolt and bushings are tight, replace one or both links.
f. With the side brace links assembled and checked, ascertain that when the stop surfaces of the two links
contact, the clearance between each downlock hook and the flat of the downlock pin is not less than
0.010 of an inch. Should clearance be less than that required, the hook only may be filed not to exceed
a gap of more than 0.02S of an inch. The maximum allowable clearance between each hook and the
downlock pin that are service worn is 0.055 of an inch. Should clearance be more than 0.055 of an
inch, replace the pin, check clearance and then if still beyond tolerance, replace hooks. The gap
between each hook should be equal.
g. Repair of the landing gear is limited to reconditioning of parts such as replacing components, bearings
and bushings, smoothing out minor nicks and scratches and repainting areas where paint has chipped
or peeled.
7-25. INSTALLATION OF MAIN LANDING GEAR. (Refer to Figure 7-10.)
NOTE
When assembling components of the landing gear, lubricate bearings,
bushings and friction surfaces with proper lubricant as described in Section
II.
a. Insert a gear support bearing (53 or 54) in each support fitting (1 or 16) and secure with snap ring (2).
Check bearing (53) for excess end play, shim as necessary with shim washers (49) (P/N 162833-44).
b. The gear housing may be installed in the wheel well of the wing by the following procedure:
1. Place a spacer washer (52) and then the forward support fitting (16) on the forward arm of the
housing. Ascertain that the barrel nut (55) is positioned in the arm and insert the attachment bolt
through washer (51) and the fitting into the arm. Tighten bolt and ascertain that the bearing is free
to rotate.
2. Position the aft support fitting (1) at its attachment point in the wheel well and secure with bolts,
washers and nuts. Install the nuts and washers by reaching through the access hole on the under
side of the wing.
3. With the retainer tube (4) for the aft arm of the housing in hand, reach up through the access
opening and insert the tube into the support fitting (1) through the hole in the web.
4. Position the gear housing up in the wheel well and install the forward support fitting (16) bolts and
washers. (One each AN960-416 and AN960-416L washer-per bolt.)
5. Push the retainer tube into the arm of the housing and secure with bolt. Torque to 40-50 in. lbs.
6. Check that the gear rotates freely in its support fittings and recheck thrust.
7. Connect the brake line to its mating line in the wheel well and bleed brakes as given in Paragraph
7-73.
c. The gear side brace link assembly may be installed by the following procedure:
1. Position the link support bracket (27) with swivel stud (26) installed at its attachment point on the
web of the spar and secure with bolts and washers.
