Re: [APD] Eheim rattle

["S. Hieber" <shieber at yahoo_com>]

I never tried putting oil on the moter parts of an Eheim,
but I never thouhgt it should be necessary -- the moving
parts are water lubricated and water cooled. If that's not
sufficient for proper operation, I would think that some
part replacement is in order. It's interesting that oil
might quiet a noisy rotor. I wouldn't have expected the oil
to remain long, being totally submerged in water inside the
motor.

How long between oilings?
