Erik,

Your strut o-rings are leaking. Mine were leaking the same way on my 360
nose-gear strut. The Legacy struts are probably very similar in design to
the 360 strut. It has 4 o-rings on the strut body assembly that slides into
the housing like a piston into a cylinder. The cap screws are there only to
keep the strut body assembly from sliding out of the housing or rotating
inside the housing. Tightening these will not do anything about the leak.

The 360 strut o-rings are a standard size -- I don't remember the size, (I
can look it up if someone wants to know) -- but I was able to get about 25
of them (Buna-N) from McMaster Carr (www.mcmaster.com) for a few dollars.
Installing them is not difficult, but you do have to make a tool to get the
assembly, with the o-rings, to slide past the cap-screw holes without
nicking the o-rings. You also have to service the strut with new oil, make
sure all the air/N2 is out of the shimmy damper, and refill with N2.

I would get some leaking at the screws and the bottom of the strut housing
after each flight. After I replaced the o-rings, no more leaking.
