impellor question

[oozy]

my powerheads stopped pumping water
i am cleaning my impellors by soaking them in vinigar,
i noticed the magnets are seperated from the plastic (impellor driver)
i was wondering if these were at one point glued togeather
it seems to make sense that they were, and now the magnet is spining but because its not attached to the plastic peice it is only spinning intermitently...
should i glue them togeather?
if so what kind of glue?
thanks

The impeller is usually "loose" in that it will turn 3/4 to 7/8 around the magnet before it "catches"...
But it is attached...
That's to help the magnet "spin up" on startup ant to have a little "give" if something gets jambed in there...
Do not glue...

If you can hold your armature(magnet assembly) in one hand and turn the impeller around 360 deg without it catching and trying to move the armature assembly, the small lug that is keyed to the armature is probably worn or broken off, and a new impeller would be needed. MOst pumps have such parts available for them. You coulkd however use a dab or two of super glue to hold impeller to the armature if the lug is indeed broken off, so you would still have water flow, until you either got a new impeller or replaced the powerhead...I would not rely on it as a good and permanent fix though.

its not the "impellor to plastic part",
its the "plastic to magnet" joint that is disconnected
like this bare with me here
ill try to post a pic later but for now...
(magnet) no connection (plastic drive) 3/4 give connection (impellor)
sorry for the lame diagram, like i said ill try to post a pic
