I recently bought an Eppendorf 5415D centrifuge, and have tried to remove the rotor for cleaning and inspection. I don't have a rotor key of the kind that is sold by Eppendorf, but the item description at http://www.capitolscientific.com/Eppendorf-022667181-Rotor-Key-for-Microcentrifuge-Models-5415-D-5415-R-10mm-Socket-Wrench seems to indicate it's just a standard 10 mm socket wrench, so I bough one of those. (https://www.amazon.com/gp/product/B0028N57SW). I attempted to use the socket wrench on the hexagonal part in the centre (see the picture), but that just makes the whole rotor turn. I tried to keep the rotor in place while turning the wrench, but that didn't work either (I couldn't keep the rotor still).
-- If I try to lift the rotor upwards, the centrifuge hangs from it and I'm worried about damagaging it so I didn't try that very hard.
The centrifuge manual (http://www.nist.gov/ncnr/upload/Eppendorf_5415R_Centrifuge_Manual.pdf) doesn't go into detail about how to remove the motor. It mentions bending the rotor to one side if it's stuck, but how do I know if it's stuck in the way which is solved by doing that?
What do I need to do?
