Use one of these in the righ size to cover the open end of the chuck after making a hole for the drill. It will keep everything out of the chuck.

Motors made to be mounted with the spindle in a vertical position have angular contact bearings to compensate for the weight of the rotor pushing along the motor rotor axis.

I have. Several: sewing machines, vacuums, washing machines, old 1/3 to 3/4hp AC motors, etc. Only the ones with pressed-on bearings didn't have some kind of thrust washer and/or oil-impregnated felt. I haven't been inside any multi-horse motors, though.

Shop vac works well, too. (during is better, but after works)

And, come to think of it, I only took apart horizontal mount motors.

They look like prophylactics for Threshing Machine accident victims.
I think it will be important for me to take the motors apart and inspect. I don't think of these things so I ask!
Smaller ones are used to seal the ends of elecrtical wire & coax. they are similar to the molded rubber caps for vacuum lines, but they don't dryrot. I have some that are over 25 years old that are still good.
Not if it's a powerful one with a long hose that lets the canister be in another room... and you forget to install the filter after a water removal process a few weeks earlier.
...don't ask how I know this. :)

Perhaps -- but don't take apart stepper motors or permanent magnet motors. You can significantly degauss the permanent magnets by doing that -- same as for magnetic chucks.
Why not just push and pull on the motor shaft to see how well it handles the gravity loads?

Ah, good point!
