2-:12. Oleo Struts.
2-33. Servicing Oleo Struts. The air-oil type oleo strut should be maintained at proper strut tube exposures
for best oleo action. (Refer to Figure

surface under
normal static load. (Empty weight of airplane plus full fuel and oil) If the strut has less tube
exposure than prescribed. determine whether it needs air or oil by rocking the airplane If the oleo strut
oscillates with
shon strokes (approximately one inch) and the airplane seltles to its normal position within
one or two cycles after the rocking force is removed. the oleo strut requires inflating Check the valve core
and filler plug for air leaks. correct if required. and add air as described in Paragraph 2-35 If the oleo strut
oscillates with
long strokes (approximately three inches) and the airplane continues to oscillate after the
rocking force is removed. the oleo struts require fluid Check the oleo for indications of oil leaks. correct if
