(3) After the filter has been replaced, tighten the cartridge to 18 to 20 foot-pounds of torque.
Lockwire the bolt through the loops on the side of the housing to the drilled head of the
thermostatic valve. Be sure the lockwire is replaced at both the attaching bolt head and the
thermostatic oil cooler bypass valve. Use MS-20995-C41 safety wire.
3. Landing Gear
The landing gear consists of tires, brakes and oleo strut assemblies. These should be inspected for
scored piston tubes, possible hydraulic fluid leakage and security and condition of all connection points.
Check the brake linings for wear and frayed edges, and brake discs for scoring. Replace if necessary.
Minor servicing is described in the following paragraphs. For detailed services and overhaul instructions,
refer to Chapter 32.
A. Servicing Oleo Struts
CAUTION: DO NOT EXCEED SPECIFIED TUBE EXPOSURES.
Air-oil struts are incorporated in each landing gear oleo to absorb the shock resulting from the
impact of the wheels on the runway during landing. To obtain proper oleo action, the nose gear oleo
strut must have approximately 3.25 ± .25 inches of piston tube exposed, while the main gear struts
require approximately 4.50 ± .5 inches of tube exposure.
WARNING: DO NOT RELEASE AIR BY REMOVING THE STRUT VALVE CORE OR FILLER
PLUG. DEPRESS THE VALVE CORE PIN UNTIL STRUT CHAMBER PRESSURE
HAS DIMINISHED.
CAUTION: DIRT AND FOREIGN PARTICLES ACCUMULATE AROUND THE FILLER PLUGS OF
THE LANDING GEAR STRUTS. THEREFORE, BEFORE ATTEMPTING TO REMOVE
THESE PLUGS, THE TOPS OF THE STRUTS SHOULD BE CLEANED WITH
COMPRESSED AIR AND/OR WITH A DRY SOLVENT.
These measurements are taken with the airplane setting on a level surface under normal static load
(empty weight of airplane plus full fuel and oil). If the strut has less tube exposed than that
prescribed, determine whether it needs air or oil by raising the airplane on jacks. With the strut
extended, remove the cap from the air valve at the top of the housing and depress the valve core to
allow air to escape from the strut piston until it is fully compressed. Allow the foam from the air-oil
mixture to settle and then determine if oil is visible up to the bottom of the filler plug hole. If the oil is
visible at the bottom of the hole, then all that is required is the valve be checked for unsatisfactory
conditions and air added as described in Inflating Oleo Struts, below. Should fluid be at any level
below the bottom of the filler plug hole, the oleo should be checked for leaks, etc, and oil added as
described in Filling Nose Gear Oleo Strut, below; or, Filling Main Gear Oleo Strut, below,
respectively. For repair procedures of the landing gear and/or oleo struts, refer to Chapter 32.
B. Filling Nose Gear Oleo Strut
To fill the nose gear oleo strut with hydraulic fluid (MIL-H-5606), whether it be only the addition of a
small amount or if the unit has been completely emptied and will required a large amount, it should
be filled as follows:
(1) Raise the airplane on jacks until the nose wheel is completely clear of the ground.
(Refer to 7-10-00.)
(2) Place a pan under the gear to catch spillage.
(3) If not previously accomplished, remove the engine cowl and relieve air from the strut housing
chamber by removing the cap from the air valve and depressing the valve core.
