Taking all the parts off, putting them back on in the correct place. I'm a retired nurse not a mechanic or engineer. Can you properly use an IV machine? Collect all the necessary items to collect and hang and administer blood? Calculate correct dosage of a given med based on wt and age category? Chances are, if you never studied to be a Dr, EMT or nurse you can't..not without having reference books. And that's all I'm saying. Nice to have a reference if you've never done something.
IMO you are over thinking things. Kegging isn't medical or rocket science. One doesn't need mechanic or engineer skills to keg our brew. Do it once and you'll know how to do it. Really not much different than changing a light bulb.
