(4) 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 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) 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).
NOTE: On models without the groove for the O-ring, apply Permatex Forma-Gasket No. 6
Sealant beneath the flange of the cylinder head (4).
(7) Install the hydraulic brake line.
(8) If removed, install the landing gear as described in Main Landing Gear - Installation, below.
(9) Service the oleo strut as given in Oleo Struts, 12-10-00.
(10) Actuate the gear several times by hand to be certain it operates freely.
NOTE: 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 (0.005) may be used as required.
Maximum side play is 0.005 / 0.007. For lubrication of links, refer to Lubrication
Charts, 12-20-00.
2. Main Landing Gear
A. Removal (Refer to Figure 2.)
(1) Place the airplane on jacks. (Refer to Jacking, 7-10-00.)
(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
compressing the 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 and the access plate located on the
bottom of the wing and to the rear of the housing by removing attaching screws.
(5) Unhook the hydraulic brake line inside the wing assembly. This is accessible through the
access plate. Cap the line by use of a threaded cap or wrapping with plastic.
(6) Remove the top four bolts by holding them with a slotted screwdriver and turning the nut with
the appropriate wrench. Remove the remaining six by use of a wrench. Carefully remove the
gear assembly from the wing.
B. Cleaning, Inspection, and Repair
NOTE: Landing gear repair is limited to reconditioning parts, parts replacement, smoothing out
minor nicks and scratches, and repainting where chipped or peeled.
(1) Clean all parts with suitable dry type cleaning solvent.
(2) Inspect gear components for excessive wear, corrosion, and damage. Check cylinder housing
and torque links for cracks, nicks, and misalignment.
(3) Use a 10 power glass to visually check cast gear cylinder top and bottom radii at drag link
attach lugs for cracks. If no cracks found by visual inspection, use dye penetrant procedure to
check for cracks. Refer to Chapter 20.
