How to change a wheel on a jumbo jet ...

[dogtag]

carefully goes without saying as the thing weighs around 500 lbs.

A Honda I had years ago did not have studs protruding, male fashion
but female threads. Trying to hold a wheel in position whilst attempting to
thread a bolt through the wheel and into the backplate was impossible.
I tried it once (no choice, got a flat). After that I inserted studs normal fashion.
Hopefully whoever designed that system had to change a tire on his own
car at night in the rain.

Interesting!

My first car was a '69 VW Squareback. Among other oddities, it had those cursed 'lug studs' as you described. They were a real pain.
The oil pan... no drain plug!.... had to be removed, about 8" across, held up by similar, except, 6 tiny brass ones... that would twist off if you even looked at them the wrong way.

Back in the 1960's I actually tried to get the Navy to try an idea to add fins to the aircraft tire rims to start them to spin before they touched the runway. If you look at a runway even today there are black skid marks where the wheels touch the runway causing unnecessary wear to the tires. It wouldn't work on 500 lb airliner tires but lighter planes... maybe.

And for some theoretical reason Chrysler used left hand threads on the drivers side of their cars. At nineteen I learned that lesson out on a lonely farm road.
Threads on the aceteline tank gauge are reversed, but there is a real reason for that. I've changed tires on the A-4 Skyhawk and the Cougar. Those aren't all that big.

I took a Boeing 727 course years ago. The 727 was a 3 engine plane with all 3 engines on the tail so if the fuel tanks in the wing were empty the plane was somewhat tail heavy and could tip over if the nose gear was jacked up or the strut extended. This plane had the aft stairs and the solution was to lower them before making repairs that involved any type of front end elevation. The DC-10, a much larger plane, had one engine on the tail and could also be tipped though it wasn't as common a problem.

When I took my 727 course years ago we got to walk around the planes being repaired in the hangers. I remember reading the print on one of the tires "skid rated 225mph max".
