INSTALLATION OF MAIN LANDING GEAR. (Refer to Figure 32-2.)
When assembling components of the landing gear, lubricate
bearings, bushings and friction surfaces with proper lubricant as
described in Chapter 12.
1. Insert a gear support bearing in each support fitting and secure with snap rings. Check bearing for
excess end play, shim as necessary with shim washers (P/N 62833-44).
2. The gear housing may be installed in the wheel well of the wing by the following procedure:
A. Place a spacer washer and then the forward support fitting on the forward arm of the housing.
Ascertain that the barrel nut is positioned in the arm and insert the attachment bolt through washer
and the fitting into the arm. Tighten bolt and ascertain that the bearing is free to rotate.
B. Position the aft support fitting 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
underside of the wing.
C. With the retainer tube for the aft arm of the housing in hand, reach up through the access opening
and insert the tube into the support fitting through the hole in the web.
D. Position the gear housing up in the wheel well and install the forward support fitting bolts and
washers. (One each AN960-416 and AN960-416L washer per bolt.)
E. Push the retainer tube into the arm of the housing and secure with bolt.
F. Check that the gear rotates freely in its support fittings and recheck thrust.

the spar and secure with bolts and washers.
When installing a new wing, it will be necessary to back drill two
(2) holes 0.250 inch and countersink 100° x .499 through the
spar cap. (Screw head should be flush with spar.) Use hole in the
support bracket as a guide in the drilling.
B. Ascertain that the upper and lower links are assembled with downlock hook, retraction fitting, etc.
attached, and the through travel of the links and downlock hook clearance checked according to
Cleaning, Inspection and Repair of Main Landing Gear.
C. Attach the upper link to the swivel stud of the support fitting and secure with bolt, bushing,
washer, nut and cotter pin.
D. The actuating cylinder rod end bearing and lower side brace link may be attached respectively to
the retraction fitting and gear housing during the adjustment of the landing gear.
4. Ascertain that the landing gear is lubricated per Lubrication Chart.
