Sta-Rite impeller remove

[plumbersmate]

I need to remove the pump's impeller to replace bearing but it won't come off!

It does not have a screw in the middle. I have checked, there no screw hidden under any cover in the centre. With the motor drive shaft impeded the impeller should screw off anti-clockwise, right?

But the impeller just rotates on the shaft but does not 'unscrew'.

Could it be that the metal threaded insert on the impeller is loose in the impeller's plastic?

I have attached a photo.

Any help appreciated.

It might be time for a new pump...if the shaft is rotating inside the impeller, replacing the bearing is the least of your worries.

Edit: what model pump do you have?
