Well, There's My Problem...

[Hugh Mann]

Reef Octopus 1000 HoB has been giving me some trouble of late. Not working as well, developed a crack in the motor housing. So I took it apart, gave it a cleaning, patched the crack and then the silly thing refuses to work. Well, I found my problem. Evidently either on its own, or during disassembly the bleedin' spindle shaft sheared off!

Fortunately both it and the motor assembly can be replaced for $110 (paid $50 for it used months ago, so still way ahead, Whoo hoo!). But still, it's going to take time to get the replacement. I'm wondering if it's worth trying to to a rough repair job in the meantime?

I would clean the broken surfaces and try gluing with some thin cyanoacrylate glue. Looks like a ceramic shaft so it should stick to it

You can easily just replace that shaft if everything else is still in working order. I did the same thing with a hot tub water pump.

That was my first thought, but I can't get the shaft out of the black end bits that keep it centered in the pump. Not sure how I would replace those.

The broken end of the shaft sits just inside the impeller. The black end pieces make it so it has to be glued like this, as I can't seem to take them off. Any way to prevent the glue from sticking the shaft to the impeller?

I was thinking maybe sticking some wax paper or something in between, but then getting it out would be a pain.

Hmm I see what you mean. Those little black things won't come off? They look like tiny O rings. Maybe if your really careful you can just use a tiny drop of glue to try sticking the two cracked ends together? It wouldn't take much.

I had same issue on an impeller shaft, glued it and it lasted till my new one came in a week later...so definitely give the repair a go.

I would use this. Its a 2 part epoxy.
Very strong stuff. I would still get a replacement.

 

[Hugh Mann]

Unfortunately they seem to be glued into the ends of the ceramic shaft. I'm going to try and super glue it, and if that failes, Epoxy. That order as it seems like it would be easier to accidentally epoxy the shaft to the impeller. So, I will see how it goes and keep you good folks updated.

Replacement is on order, but it's estimated 2-3 weeks.
