My hayward super pump 1 1/2 hp model 1610Z1M making a noise. I don't think it the bearing because no noise on start-up but after 2 or 3 minutes makes a noise. I've tried to attach a drop box video with audio.
the rear of the armature seems to be bucking up and down a bit causing it to strike something inside the casing. is there a seal or something i can replace to keep the armature held steady?
