When mechanical parts explode all the magic noise leaks out all at once, and it stops working.

You can sometimes get some of the magic noise back into the parts by yelling at them, hitting them, or bashing them with a hammer

but usually they have to go back to a machine shop, where they can be pumped full again by the noisey machines.

Mechanical parts are only suppose to give out their magical noise a little bit at a time!
