    This is the replacement motor and impeller. The old motor and impeller had the same problem. Impeller treads stripped, motor smoked and quit.

  • ml_cole Dec 13, 2009

    The other motor's shaft was had to turn. The bearings were bad. The shaft in the new motor turns freely and doesn't make a griding noise. The impeller is also new. As I said the impeller brace nut is shredded. The motor maqde a popping noise, smoked and shut down. The old motor did the same thing.

  • ml_cole Dec 13, 2009

    Is it possible, when it was mounted to the strainer housing basket, it was tighten too tight. In addition, what was the popping and where did the smoke come from? Also, the motor lines up perfectly when mounting.



    The old motor was just a year old and did the very same thing.

Motors can be rewound, impellers can be replaced, You have severe damage, I suggest you replace your pump and motor...it will not only likely be a less expensive fix, but a more dependable and efficient one as well. You can get a deal on e-bay, (Save lots of bucks over what the pool shop would charge). Good Luck! I hope you find this to be very helpful!

    I just got to read your comments. The impeller broke and caused your motor to burn up. Something is not lining up properly. The issue with the motor not turning properly indicated a fault with it, but until just now, I didn't realize you had already replaced both. Before attaching your replacement motor, make sure your impeller assembly is turning properly. (shouldn't bind) . Good Luck!

    impeller shaft bearing sounds like it maybe bad. have you check that yet or replaced it with these replacement?

    michael schultz Dec 13, 2009

    with out seeing it is tough but i would have to say there is something mis aligned or something just off enough to cause failure. how long did the replacement last? if it was a while it maybe so slight it will be hard to see with the naked eye. if it was right away then there is something there you may be missing. can you sens me a picure of it. i may be able to spot something.

    it could have been tighten to much that is very possible. the poping and smoke it the motor's armature/windings and brushes failing and the smoke if from that happening. that is the best i can do with the info i got from you. hope that helps let me know if you have more questions. good luck

Remove the 6 bolts holding the motor mounting plate to the pump housing. Back the motor assembly out. Remove the diffuser and you'll see the impeller. Using picks and wire run through all of the impellers vanes to clear out the debris.

I am rebuilding a Northstar pump. I thought I had an o-ring between the diffuser and the impeller ring when disasembling. I don't see the on the schematic however.


The impeller ring moves freely and does not use an o ring. The front of the diffuser does have one. It sounds like they gave you an extra. BTW I have found that Northstar pumps get about 4 years out of their motors. That is about half the average life. I hope you are getting longer than 4 years. If not, it may be worth changing to a different pump.

Just cleaned filters and reinstalled them and the flow is only about a fifth of normal. I noticed that the filter basket on the pump was cracked and was wondering if debris got through if the pump...


How old are the cartridges? They last 2-4 years depending on operating conditions beyond which no amount of cleaning can bring them back.

To check your impeller simply remove the six bolts holding the motor and moving parts of the pump into the housing and pull the motor back out. The diffuser sits over the impeller and it may be there or still in the housing. It aligns over the impeller with pegs and only fits properly in one orientation. If it is over the impeller pull it off and check all the impeller vanes for debris. Clean it if necessary.

If there is nothing in the impeller consider replacing the cartridge or the possibility you now have a clog somewhere else in the plumbing.

My hayward super II pump output return pressure to the pool is very low.. The PSI readings seem normal and I can't see any visible blockings... How else can I test? What can be the problem?


Thank you for posting your question here on Fixya.com.


Start with the impeller and strainer baskets. Excessive debris in the basket(s) in front of the pump can reduce flow rates. Another possibility is debris lodged in the impeller vanes. If the baskets do not solve your problem shut down your pump and back out the 6 bolts holding the motor into the pump housing. Pull out the pump end and remove the diffuser covering the impeller (sometimes the diffuser sticks inside the housing and the impeller will already be uncovered). Use a zip tie or something else of similar strength to run thru each vane looking for things such as small toys, marbles, rocks, mulch etc. Once cleared reassemble the pump being careful to align the diffuser back over the impeller and into the pump housing correctly.

If nothing can be found in the impeller and the baskets are all cleaned and still you have reduced return pressure you will have to get into your filter to find the trouble. If you get that far, please post a comment with what brand and model filter you have for more guidance.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!

Looking to replace my elec. motor on my hayward pump # sp3605x7. ser# 640c30. not sure how you..remove the motor from the pump.did not see a set screw? thank you steve 978-606-9706.


Turn off the electric first. Then just remove the 4-6 bolts and separate the back half from the front. The motor with seal plate, impeller, and diffuser can all be pulled back away from the rest of the pump. Now disconnect the electrical from the motor and your can pull the motor with the seal plate, diffuser, and impeller all the way out and work on it. You need to remove the diffuser (plastic housing that goes around the impeller) sometimes this is held by a series of 3 to 6 small screws, other times it just slips over the impeller. 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 one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should 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 (it should be counter clockwise 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 replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white and black ceramic surfaces 100% free of any dirt, grease, etc while working with them. The instructions above a based on a very similar model and may vary slightly, let me know if something doesn't look/sound right and I'll clarify. Good Luck

Tryiing to replace motor cannot get diffuser and seal plate free how do they come apart


First remove bolts holding motor to wet end. Pull motor back and out of wet end. Diffuser should just fall off. Not held by anything, there are just some locating tabs. Next, unscrew impeller. Some impellers may have a screw holding it on to center shaft. If so, unscrew.(Backwards thread). Remove back cover on motor and hold centershaft with large screwdriver or wrench on flat of shaft. Unscrew impeller. Next, unscrew 4 bolts holding motor to seal plate.

Leak between seal plate and pump/strainer housing


The pump seal is leaking and needs replacing and requires removing four 3/8 bolts (9/16) wrench and removing the motor then the diffuser to get to the impeller and seal . A 7/16 wrench holds the rear motor shaft behind the springs and impeller spins off to reveal the seal which has two parts one on the impeller with a spring and one in the seal plate is white ceramic/ porcelan whatever they use. Part number is an SPX1600KA on super pumps and 1500KA wassome above grounds. When replacing do not touch the mating white and black surfaces with your fingers.

Changing motor hayward 1.5 HP


Super pumps are very easy. If it is a northstar it is more difficult. Super pump. You will need 1 motor, 1 pump seal, 1 diffuser gasket, 1 housing gasket. turn off breaker, disconnect wires -noting whether it is 110 or 220 volts- , unscrew four bolts on back of pump housing (shaft side of motor), pull out motor with rear housing and diffuser (sometimes diffuser sticks inside), on wire side of motor hold shaft with wrench (flathead in some cases, but it is harder), unscrew impeller counter clockwise (like normal screw - you will nee a big pair of channel locks or a strap wrench), there are two pieces of the back housing and once the impailer is off you can remove the half that is closest to the end of the shaft to reveal four more screws, unscrew those four screws. screw back part of rear housing onto new motor. Install new pump seal to front part of rear housing and impeller, slide on front part of rear housing and then screw on impeller while holding shaft on wire side with wrench (only hand tight), replace housing gasket, replace diffuser gasket, slide into front housing and screw in four bolts. If electrical was 110 you will need to move the jumper on the wire end..if it was 220 then just hook kup wires...doesnt matter which is which as long as green or bare goes to the ground screw.
