Eheim Classic Axle And Bearing

[Captain Neon]

During my 6-monthly filter clean, I accidentally snapped off the bottom 2 centimetres of the ceramic axle (prop shaft) for the impeller on the Eheim 2213 Classic filter. The impeller still works, albeit noisily, I think mainly because of the vibration caused by the prop shaft being too short now. (Thank goodness, otherwise I'd have no filter! ) I've been able to order a replacement part which will arrive in the next day or so, and I'd like some advice as to how to safely remove the old axle and replace it without breaking the new one. Apart from the exploded view diagram in the set-up instructions, I have no idea of how to safely do this. Is there anyone here who can impart their wisdom?

Taking the whole thing to bits is not difficult and can be done with 2 screwdrivers....

...but I'm confused. You must have had the thing in bits in the first place in order to accidentally snap the thing.

PS
How are you cleaning it? I found them a sod to clean.

Hi Andy,
I cleaned the media in tank water during a water change (As one should,) and the impeller itself was partially clogged with brown goo. The impeller housing has a twist-lock cap which comes off, then the housing cover proper pops off after that. It was when I tried to remove the impeller itself that the shaft snapped; luckily I had an impeller removal tool for my Fluval (On the other tank) that I could use to hook the impeller off with, so I could inspect the damage I caused. (Why don't Eheim give you the same tool? It'd save a whole lot of hassle!) As I said, only the bottom centimetre or so came off, so there was enough shaft for the impeller to revolve around. all I did was give the impeller and the housing a quick wipe with wet hands to remove the excess gunk before putting it back together- and the darn shaft snapped! If they made the shaft from Nylon or some kind of plastic material, like some of the Fluval pumps are, it would most likely not have snapped...

Heaven knows how you managed to snap it but I guess it may have just been worn out. I know not of the impeller removal tool, however the impeller on my 2213 is simply a blade on the end of a nylon shaft around which is a barrel shaped magnet. The magnetism of the magnet holds this impeller assembly in the hole. In other words, to remove it, simple grab hold of the blades and pull the whole thing out.

Simple as that.

It was grabbing hold of the blades that led to the ceramic shaft breaking. The impeller removal tool is a hook, designed to hook around the impeller blades and pull the assembly out. The filter is only 6 months old, so I don't think it was worn out; it was probably my sausage fingers trying to get hold of the darned thing!

Make a hook out of wire.... anyway, it did not take me a lot of force to get it out. I'm thinking that perhaps your alex got gunked in place and got stuck....
