4 When air bubbles cease to flow through hose, compress strut fully and remove hose
from valve stem.
5 With strut fully compressed, remove filler plug to determine that fluid level is visible
up to bottom of filler plug hole.
6 Install core in filler plug. Apply an appropriate thread lubricant to threads of filler plug
and install plug in the top of strut housing. Torque plug to 45 foot-pounds.
(b) Method II:
1 Remove the filler plug from the top of the strut housing.
2 Raise the strut to full compression.
3 Pour fluid from a clean container through the filler opening until it is visible at the top
of the strut chamber.
4 Lower the gear until the wheel touches the ground and then fully compress and
extend the strut three or four times to remove any air from the housing.
5
Raise the strut to full compression and if needed, fill with fluid to the bottom of the
filler plug.
6
Apply thread lubricant (Parker 6PB) to the threads of the filler plug. Reinstall the filler
plug and torque to 45 foot-pounds.
(5) With airplane raised, retract and extend gear strut several times to ascertain that the strut
actuates freely. The weight of gear fork and wheel should extend strut.
(6) Clean off overflow of fluid and inflate strut as described in Inflating Oleo Struts.
(7) Check that fluid is not leaking around the strut piston at the bottom of the housing.
D. Inflating Oleo Struts
Make certain that oleo strut has sufficient fluid and that torque link is properly connected. Attach a
strut pump to air valve and inflate oleo strut to proper visible piston extension, or a pressure of 250
± 25 psi (for the main gear struts) and 225 ± 22.5 psi for the nose gear strut.
When using pressure method pistons must be fully extended by raising aircraft off ground. (Refer to
7-10-00.)
When using the extension method, the aircraft should be fully serviced with fuel and engine oil and
resting on its landing gear. Inflate strut until correct inches of piston is exposed. Rock aircraft several
times to ascertain that gear settles back to the correct strut position. If a strut pump is not available,
raise aircraft and use line pressure from a high pressure air system. Lower aircraft and, while
rocking it, bring strut down to proper extension by releasing air from valve.
Check for valve core leakage before capping valve.
