Aircraft Oleo, Air Oil Shock Servicing. Cessna 150 172 Piper PA28 

Truly appreciate you sharing your knowledge and experience.

Nicely done! Short and succinct and easy to understand. I thought nitrogen was used to prevent moisture and oxidation.

so you started with a strut with no oil in it. How did you get the old oil out of the strut?

Nice! Thanks!

How much oil goes in?
