I don't understand what advantage this has over simply deflating the strut,
removing the schrader fitting, filling it to the brim with 5606, replacing
the schrader, and pumping it with a gas (air or nitrogen). You can argue
for nitrogen if you want, but the sloshing of the 5606 inside that strut
keeps it pretty well oiled for plain old air. Besides, nitrogen comes out
the spigot at a pretty good pressure, and you can adjust an air compressor
down to where it won't blow the piston out the bottom of the strut.

These are the most wonderfully engineered oleo struts in the world. They
are easy to rebuild and easy to service.

Filling one with 5606 hydraulic fluid, however, is not best done by the
book. You slip a tube which fits tightly over the schrader (with the
stem
removed) and the other end of the tube into your can of red hydraulic
fluid.
Then you pull out the collapsed strut to its full extension, thereby
sucking
5606 fluid into the hollow strut.
