what it the "bicycle pimp" device for? The N2 is at high pressure from the tank. Is that used for pressure or an extra cutoff valve so fluid doesn't back up in the tank accidentally?
Tim Kiehl, Yes, the “Bicycle” Pump boosts the Nitrogen Pressure from a lower pressure nitrogen supply tank. You could even use “Air”, but this is not recommended as Air has moisture/water vapor and oxygen which can cause problems in the strut/seal. Alternatively, you can have a High Pressure nitrogen tank, full enough to still have high pressure and valve/regulator with appropriate hose and aviation Shrader-valve connector. Typically, you would use wing jacks to lift and remove weight from the aircraft or alternatively you could bounce the strut with an assistant who carefully lifts the wing along the spar so as not to bend anything and jounce the aircraft up and down until it settles, then add or release pressure to adjust correct exposed cylinder length to specifications.
Worth noting the reason you’re stranded with a flat strut is because if you try to taxi and take off, you’re probably going to hit the prop on the ground
30 minutes to get it on jacks? Our school mechanics push the tail to the ground and leave a sandbag on the elevator 😂

If I have trim position between green line, I think flare flare it can’t hard
You blasted through the part about regular strut maintenance btwn service
