Yes, bearings can be replaced, but that's a slightly more detailed DIY-type job which might require some specialty tools if you're not already equipped to do so. Often times when a motor needs to be replaced, owners will simply un-bolt and remove the motor assembly from the pump basket. Replace a seal or two, perhaps the diverter/impeller if needed, reconnect the electric, and be on their way. You should be able to Google your motor model/part number for replacements. Or you can contact Inyopools.com for some part availability. They have quite an extensive product line when you get ready.
