If you see water leaking out of the bottom of the pool pump assembly, it's a good indication that you may have to replace the shaft seal within the motor pump assembly. As shown in the pool pump cutaway, the shaft seal is located in the motor pump assembly behind the impeller. Although this description is specific to a Hayward pool pump, many of the steps can apply to other models of pool pumps.
The first step is to turn off all power to the pool pump. For maximum safety turn off the power at the circuit breaker to the motor.
Next, you will want to remove the motor pump assembly from the wet end housing. Remove the four 9/16" bolts that bind the motor pump assembly to the housing. Note: some Hayward pool pump models have six bolts. Now pull the assembly apart from the pool pump housing.
After the assembly is out, you should see the pool pump diffuser and diffuser gasket at the end of the assembly. If you do not see the diffuser or its gasket, check inside the housing. If the pool pump diffuser came out with the assembly, pull the diffuser off the assembly. You may have to pry it off gently with a screwdriver. Now you will see the pool pump impeller. The shaft seal is behind the impeller so you will now have to remove the impeller. To remove the pool pump impeller you will twist the impeller off in a counter-clockwise motion. The impeller cannot be freed from the motor shaft without first securing the motor shaft. Move to the other end of the motor shaft in the back of the motor assembly. Take off the two screws that hold the back cover onto the pool pump assembly. You will see the pool pump motor wiring and capacitor. You will have to remove the capacitor to gain access to the end of the motor shaft. Capacitors store power. To avoid a possible shock, lay a screwdriver across the two leads to short out the capacitor. These capacitors sometimes burst when shorted out, so it is a good practice to place a cloth over the capacitor and to wear eye protection.
Now unscrew the single screw that hold the capacitor in place and push it out of the way. No need to disconnect the capacitor from leads.
Place a 7/16" wrench on the flat end of the pool pump motor shaft to secure the shaft from rotating.
At the pool pump impeller end, twist off the impeller, counterclockwise. You may have to use a strap wrench to gently free up the impeller. Now you will see the motor shaft seal. One half on the pool pump impeller and the other half in the seal plate on the shaft.

Great video! Sincerely appreciate the effort.
Thank you for sharing. good video.
Thanks, this is exactly what I needed to do everything was clear and simple to follow, and you really helped. Thanks
Thanks Eric! We are glad this helped out, if you ever need any assistance with your pool let us know.
Thanks for the great video. Showed me exactly what I needed to do to replace my shaft seal. 5* -- five stars for you!
Very helpful. Thank you!
You're welcome!
good info
According to my Hayward manual you have the white impeller ring on backwards. If you look at the end of the ring it says this end toward the strainer basket.
John Essley Very good catch John, the impeller ring is backwards in the video. We took this pump apart several times in the shooting of this video and it looks like our tech messed up one of our takes. We will work to correct the video.
Thanks for keeping us on our toes!
great video....thanks...
Good video, except I agree with comment below. Never!!! use a screwdriver or anything metal to seat the white ceramic seal!
Also, while you already have it all apart, replace the diffuser seal and the housing seal. They come in a "seal kit" with the shaft seal. Just a few more $ to do them all.
Exactly!. We do have these things called gloves now.
Great video tks!!
Glad you liked it!
Dam good video!
Pump not leaking anymore. Thanks !!!
Killer soundtrack!
Thanks for this vid. It really help us to fix the leak in our unit. :)
Awesome, glad to help. :)
Does anyone know what the plastic piece with the V metal tabs at the base of the motor shaft is called? Mine cracked during the replacement. Thanks
Clear concise How-TO video of how to repair a Hayward pool pump. Just one thing that is distracting - the "Rack Focus" technique that the camera operator used was used a little often. IMO, the operator should keep close-up details in focus, rather than "Rack" the focus point away and making things OOF (out of focus). Otherwise, the video was helpful towards understanding how to fix the Hayward pump.
Hi Brian thanks for the input we will keep that in mind when we create out next video.
what happens if you tighten the bolts in any pattern other than the order shown? will it leak?
I have the same pump housing as what's shown, I don't know if the actual pump motor is the same. I have a 2.20 Century ST1152. Can you tell me if a go-kit2 still will fit this before I take this unit apart? The housing is a super II.
+Karen Miller Yes the GOKIT2 is the correct gasket kit for the Hayward Super II. If you have a saltwater pool I suggest using the GOKIT2SALT which comes with a heavy duty shaft seal.

Could this cause your pump not to prime, I mean the pump comes on i see a leak and the water is not flowing through.
The seven-year-old video just saved me about $200! Thank you!
Good video but you should never touch the white part of the shaft seal with a screw driver or any tools or your hand (fingers)It should be pushed in with out touching the white part of the seal very carefully any scratch or body oil on the seal and it will go bad.Use a piece of cardboard or the plastic it came in to push it in and some seals come with a little lube kits but only to be used on the black rubber part on the back side of the seal.I just wanted to give a little of my info just to help out :)
+ddanster91 Thank you for the comment and we do realize our video makes the mistake of using a screwdriver to install the shaft seal. That's a price we paid for using presenters instead of using our actual on-staff techs. We do have annotation in the video stating it is not the correct way to install a shaft seal but the note does not show up on the CZcams phone app.
We will be posting a new How to Replace a Pool Pump Shaft Seal video soon. The new video will be new, improved, and accurate. Thanks again for the comment.
Why is this so vital? I did not know this tip till after I reinstalled new pump to my housing. Now I've got a leak under pump housing and also leak at discharge outlet on top of Hayward SuperPump. Pump struggles to prime.
I replied about this as soon as I seen the video there are some more videos out there that are more in detail
I just did all this and water comes out around the motor. The lady at Leslies pool took the white seal out while I was in the store and pushed it in with here fingers. Is this why I have a leak? And mine was just rubber or plastic, not anything even remotely close to ceramic.
I am assuming your bolt tight count sequence starts as no. 1 from the left and it goes around to right for 6, right? Or, it doesn't matter which bottom end you start count as long as you follow sequence?
We will typically start one bolt and then go diagonally and then start the opposite one. For example, start with the bottom left and then go diagonally to the top right. Do the same for the bottom right and top left. Then you can tighten the middle bolts if your pump has those.
got it, thank you
hey mate , what do you do when the pump has been in service for some time and you can't get the impellor off ?
+lozarok The first thing I would try is a strap wrench because they they are the least likely to hurt the impeller. I have had people tell me to use WD-40 but it is almost impossible to get the spray to the threads of the impeller.
Vice grips can also be used but they pose a higher probability to cause damage to the impeller. If vice grips grips do not work, get a hammer and prepare to buy a new impeller. ;)
Cheers for the info mate !!!!
Ok, I get it now. That piece is actually part of the new seal.
I just performed this service to my pump today...when I turned pump on the waste basket compartment filled with smoke!! I shut it off and took it all apart again. The porcelain seal that you press in behind impeller was toast. It got so hit and cooked the rubber seal around it ruining the part. I am so confused to what I did wrong!?
+joegolden481 I would confirm proper seal installation as well as diffuser impeller alignment. Friction and running dry for extended periods would be the only things that would be able to cause that type of reaction around the mechanical seal.
Does it matter which way the Impeller Wear Ring faces?, I've seen other videos which show the ring with the fatter end facing out.
Acme1970 Yes it does matter the orientation of the impeller wear ring's lip. The lip of the wear ring should be butting against (or close to) the diffuser rather than the impeller disk. Good eye, catching the little flaw in our video.
+Inyo Pools I was just thinking the same thing, LOL. Also, isn't there supposed to be a rubber gasket on the end of the diffuser which goes into the pump housing? It's not on there when you pulled out the diffuser. Who the heck put that pump together!? LOL.
EDIT: Oh wait, I see you added one at the 6:00 minute mark. But it wasn't on the diffuser when you removed it from the impeller housing at the beginning of the video.
And, if the fatter side of the impeller gasket is against the impeller disk as you have it, will it also cause a slight leak under the house pump? That is the way I have it as shown and the housing assembly is letting out slight leaking. Thank you.
What Hayward model is this, it's the same as mine and I can't read model number to make sure I get the right replacement parts.
+Karen Miller The pump used in this video is a Hayward Super II Pump. The following link is a parts listing for the Hayward Super II, so anything you need should be here: www.inyopools.com/pool_parts_hayward_super_2.aspx
+Inyo Pools You guys are great. thanks!
+Deanna "babygirl1213" Hudson A bad shaft seal should not cause a loss of prime. A bad pump lid gasket, diffuser gasket, or union/valve gaskets before the pump is a more likely source.

Hello, I just replaced my motor from one I bought from inyo and I used a go kit. I did everything that was pointed out in the video but now I have a leak under my new pump? It runs fine but leaks. I replaced all the seals with the kit for a salt water pool. Should I take it back apart and try again? Help
Yes take the pump apart and reapply the seals and gaskets carefully.
The white plastic seal on the impeller is backwards. You corrected it in your new video.
That silver metal piece on the impeller. Do you need that? The impeller that I bought does not have it
+David Rise That metal cuff on the base of the impeller was actually a piece of the old shaft seal. Remove that leftover piece before installing the new shaft seal.

Do shaft seals come in1/2 inch and 5/8?
There are shaft seals for 1/2" shafts. The 5/8" shaft seal is more common for pool and spa motors.
Looks like you have the impeller ring on backwards. My manual shows the wide end facing the suction side of pump.
The impeller ring is backwards in the video. The wide portion should face the basket/suction side.
So HOW DO YOU get the seal onto the impeller without breaking anything?
My seal is not going on properly! I could put it on upside down, and it would seat easily.
Did you completely remove the old shaft seal from the impeller? Sometime a metal cuff will stick to the shaft of the impeller. It looks like it may belong but it needs to be removed. We discuss this in the new shaft seal video. czcams.com/video/Moy34mj_7To/video.html
I have done this several times in my 23+ years as an adopted pool owner. I have never seen the white collar on front of the impeller as seen at 1:27. Should there be?
The white impeller ring is not used on all pump models. Check out a parts diagram of your pump to verify if your model required one.
@@Inyopools thank you for the quick reply! It doesn't.
But you used the sharp end of the xrewdriver
What about the defuser seal on impeller
Good catch. There is a lot in this video that needed to be corrected. Back in 2013, we paid people to come in and shoot the videos. Some steps got lost in the process. We now do the videos with experienced pool techs on staff. We shot a newer version in 2017. czcams.com/video/Moy34mj_7To/video.html
what if I manage to touch both of those "don't tuch" rings (white and black) prior finding this video?
***** carefully wipe with a dry, clean cloth and attempt to reassemble.
Inyo Pools Thank you :) I already got it running again. In my case the engine wouldn't spin because these two surfaces were somehow baked together. I was just afraid I might have started some chemical reaction by touching it..
+james collier I know (ugh!) not our finest moment. For this particular video we had one of our video guys to do the shaft seal swap out and he did not do it accurately in that section. For all of our video's since this video we have our pool techs in the video. We plan on re-shooting this video during the off season. Thanks for the comment!
I change pump seal and gaskets
But after put together there is a leak between plate and housing
Gasket is in the groove and i silicone in and out of gasket so plate squished silicone out all around pump and plate but star leaking right on top between plate and housing i even
Let silicone dry for a day and pump keep leaking wtf do this happen to u ? How u fixed
Should just buy beter brand because Hayward super II sucks
This is my third time i take a part and put together and still keep leaking not by seal but by top between plate and housing
any luck fixing, i have the same issue...
Yes I buy a the pump housing and plate it came together with the seal , gaskets, defuser and basket.
I took it at part for the last time finally 😂😂😂 no more leaks
I recommend to get some high temp pump union also , now is time to install
Hayward give 1 yr warranty My pump is nearly 2 old and it’s already up for a new seal👎 Nice product . Consider buying ? consider maintenance every couple of years! I give it 1. 5 star rating !!!
Lol don’t touch the ceramic seal; but jam it with a screwdriver and pliers is alright.
How about Take the old shaft seal and use it to press in the new shaft seal.
If the impeller was able to be screwed off by hand, we wouldn't need a video !
For an updated version of this video, following this link: czcams.com/video/Moy34mj_7To/video.html
The constant focus/out of focus makes the video tough to watch.
Don't touch with your fingers, but use screwdriver?? and scratch it🤣
Here is a link to the updated version. czcams.com/video/Moy34mj_7To/video.html
Please keep it in focus. It makes my head hurt
Just once, I would like to see a realistic how-to video. The kind of video that depicts how a real home owner would be replacing a part. A video where the pump motor is wedged between a sand filter and a brick wall with the PVC plumbing and wiring connected (power disconnected at the breaker of course), and not completed removed and sitting on a workbench. Then you would see it takes longer than 8 minutes and 12 seconds to replace this part. If want to make it a night time repair because you had to get the kids to bed and have 100 percent humidity at 8:26pm, then it would be even more realistic. Thanks. Now back to my shaft seal repair.
By the way, my husband made that post. He's the best.
That is not how to replace a seal. The rubber gasket that goes around ceramic should also been replaced. In the hayward go-kit it all comes as one part. You surely don't force it in with a screwdriver and needle nose pliers. This guy really got it wrong. I've done it for thirty-five years
+Brook Wade you are absolutely correct. We had one of our Non-Pool guys do this video and he definitely got that part wrong (screwdriver part... ugh!). We will be re-doing the video with some of our pool experts staring in the video. But I still think the majority of the video is helpful. We will keep you posted when the new video is out.
We have made an updated shaft seal replacement video, watch it here: czcams.com/video/Moy34mj_7To/video.html
Can someone please explain why you shouldn’t touch the ceramic or graphite faces? Seems weird to me.
Preferably a scientific explanation rather than ‘ because I said so ‘
Hi, the oils on your skin can break down and degrade the shaft seal over time. Our updated shaft seal video mentions this: czcams.com/video/Moy34mj_7To/video.html
DO NOT use sharp or hard objects as shown in this video! Really? Why are you showing the use of sharp, hard objects if that's not what you are supposed to use? Informative video but WOW you need to reshoot that part showing the proper proceedure. A socket wrench is a good tool to seat the seal.
We agree this video was wrong on a few aspects of changing the shaft seal. We have since made an updated video, watch it here: czcams.com/video/Moy34mj_7To/video.html
These dudes don't know what they're doing
