How do I remove existing motor and replace it with a new one ? Hayward 2.0 hp # SP2615X20 Thank you
Turn off the electric first. Now split the pump in two by removing the large clamp or 4-6 bolts holding the two halves together. (not the 4 bolts holding the motor to seal plate, but the the bolts holding the seal plate to the seal plate housing). Once you remove the clamp or bolts, the motor with seal plate, diffuser, and Impeller can all be pulled back away from the pump. Then disconnect the electrical from the motor and you can pull the motor with the seal plate, and impeller all the way out and work on it. To get to the impeller, you need to remove the diffuser (plastic housing that goes around the impeller) usually by a series of 3 to 6 small screws. To remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tail piece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under the thermal overload switch, or removing the capacitor for even easier access. Once you've locked the shaft, you can just unscrew impeller. If the impeller has a bolt or screw in the middle remove that first. this screw will be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. Make sure to replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white ceramic, and black graphite surfaces 100% free of any dirt, grease, etc while working with them. Installation is pretty much just the reverse. Install half the seal into the seal plate. Install the seal plate onto motor and bolt into place. Install other half of seal onto shaft. Screw impeller onto shaft and install screw (if one was there to start with) in center of impeller (reverse thread). install diffuser over impeller make sure it is centered and doesn't rub the impeller hub. Install new diffuser and valute o-rings. Hookup wiring before re-attaching to rest of pump. Clamp or bolt back together. Pour plenty of water into pot to prime and flip the motor on for a sec or two. Pour some more water. Install pot lid. You should be good to go. Keep in mind there are many different pumps and some variations to the above instructions, but the above should cover most situations. Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave a good thumb rating if you found this helpful. Thanks, and good Luck!
