Each wheel assembly will require one wheel shell, two bearings and one precision shim:

Push a wheel shell over a bearing:

Then, place another bearing with a precision shim on top of it:

And push the remaining open side of that wheel on it:

If the precision shim would prevent you from pushing the bearings well in place, then you can use a hex driver or something fine (tooth pick etc) to reposition it a little bit, so that the bearings can be pushed well in place.

Do this for all 48 wheels
