I am trying to find out how to remove the impeller on an intex model sf15110 sand pump to replace the bearing on the impeller side of armature. I read a forum member's july 2013 response to replacing bearings but he never showed or said how he removed impeller when he replaced his bearings. My son has same setup with model sf15110, his was froze up but with a little wd-40 I managed to free it up. I plan to drill a small hole in old bearings and use motor oil until I can replace them.
