That "resistor" / wear indicator. I looked that from old one... I cannot understand how that "inductor?" can measure wear from the plain cover of the motor (on the inside theres no any holes on metal, what could measure rotation or anything?) . Looks a bit like BS to me.

Ok, if it measures the wear from main socket some funny way, but then what is that two wire additional small socket.
I am not sure exactly how it is set up, but it measures wear on the fluid through resistance change. As fluid wears and pucks up contaminants, you can use this to measure wear.

I don't know if it flows through sensor or if there is another pickup somewhere in the case.
