ADJUSTMENT OF MAIN GEAR DOOR ASSEMBLY.
1. Place the airplane on jacks. (Refer to Jacking, Chapter 7.)
2. Ascertain that the main gear is properly adjusted for gear up as given in Adjustment of Main Landing
Gear.
3. Adjust the retraction rod end at the door so that the door will pull up tightly when the gear is full up.
Over-tightening may result in door buckling; however if the door is too loose, it will gap in flight.
4. Check all rod ends for adequate thread engagement, for safety and tightness of jam nuts.
5. Remove the airplane from jacks.
NOSE GEAR.
DISASSEMBLY OF NOSE GEAR OLEO. (Refer to Figure 32-4.)
The nose gear oleo assembly may be removed and disassembled from the gear oleo housing with the gear
removed from or installed on the airplane.
1. Place the airplane on jacks. (Refer to Jacking, Chapter 7.)
2. Place a drip pan under the nose gear to catch spillage.
3. Remove air and fluid from the oleo strut. Depress the air valve core pin until strut chamber pressure
has diminished, remove the filler plug and with a small hose siphon as much hydraulic fluid from the strut as
possible.
4. To remove the complete cylinder and fork assembly from the oleo housing, cut safety wire at the top
of the unit and remove cap bolts that attach steering arm and aligner guide bracket to the top of the oleo
cylinder.
5. Disconnect the shimmy dampener by removing each cotter pin, nut, washer and bolt that connects the
dampener to the oleo cylinder and housing.
6. Release and remove the snap ring and washer(s), if installed, at the top of the housing, and pull the
complete cylinder and fork assembly from the bottom of the housing. The upper and lower housing bushings
should remain pressed in the housing.
7. To remove the piston tube and fork from the cylinder, first separate the upper and lower torque links
by removing the link connecting bolt assembly and then separate the two links. Note spacer washer between
the two links.
8. Compress the piston tube, reach up along the tube and release the snap ring from the annular slot at the
bottom of the oleo housing.
9. Pull the piston tube with component parts from the cylinder.
10. The piston tube components may be removed by reaching in the tube and pushing out the upper
bearing retainer pins. Slide from the tube, the upper bearing, lower bearing with outer and inner O-rings, wiper
strip, washer and snap ring.
11. To remove the orifice tube, remove the large lock nut and lock washer from the top of the cylinder.
Pull the tube from the cylinder.
12. The orifice plate is removed from the bottom of the orifice tube by releasing the snap ring that holds
the plate in position.
13. To remove the piston tube plug with O-ring located in the lower end of the tube, remove the bolt
assembly and insert a rod up through the hole in the body of the fork. Push the plug out through the top of the
