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 cut away, 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.

I brought a new Hayward replacemenpump, and I forgot to order the go-kit, and it started to leak. I ordered the go-kit and followed the instructions and now is working 100% thank you for the instructions they're very important. Thank uReply

I just replaced my sp1607 pump with a v-grren pump. I got everything from you all and followed the video (very helpful!) for replacing everything. Now I'm getting a water leak from under the mounting plate. When I tighten the mounting bolts a bit more the leak stops. Does this suggest I may not have put the shaft seal on properly or just that I haven't sufficiently tightened the mounting plate bolts? All seals were replaced when I replaced the pump motor.Reply

There are only two gaskets that could cause a leak there, and that is the housing gasket or the shaft seal. I would break down the pump to make sure everything is installed correctly. While you have it apart, check for any cracks in the seal plate, just in case.Reply

Made the mistake of not removing all of the shaft seal. I was lost until I ran into this. Thank you so much for saving the day.Reply

Changed shaft seal on Hayward super pump and still leaks what could it be.Reply
InyoPools Product Specialist Matt S. Posted: 7/15/2019
Either that shaft seal is not sitting correctly, or there is a crack in the seal plate. The seal plate is key 13, on this parts page Hayward Super Pump SP1600 & SP2600 SeriesReply
Jorge RODRIGUEZ Posted: 7/15/2019
Thank you I will check seal plate and will get back to you thank you againReply

WARNING: Make sure you remove the hex screw from the impeller before trying to unscrew it off the shaft. The steps above do not mention this but Hayward pumps/motors have a hex screw that is reverse threaded and locks the impeller in place. I sheered mine off thinking it came off with the impeller. It does not. You must unscrew it (turn it to the right, not the left) before unscrewing the impeller.Reply

I replaced a Go-kit 1 in a Hayward Max flo pump and when I went to use it water was coming out of the bottom near the motor, I followed the video and did every thing right I believe, never touched the white part and just to be sure I wiped it with a clean cloth prior to assembly. What do you sugest? buy another kit and try again? Or can a I salvage what I got and try again?Reply
InyoPools Product Specialist Matt S. Posted: 6/20/2019
I would take the pump apart to check the housing gasket; if that seal got pinched when assembling the pump the leak can resemble a bad shaft seal.Reply
Alan Posted: 5/14/2019
I had a pump shaft seal go bad. I ran the pump a few hours with the seal leaking. I then replaced the seal, and now my pump is squealing when it runs. Do I need to replace the motor bearings and another shaft seal?Reply
InyoPools Product Specialist Robert M. Posted: 5/14/2019
Just to be safe, we would recommend replacing the shaft seal when you replace the bearings. The shaft seal you just installed may be ok but it would be a pain to rebuild the pump only to find out that it is leaking again.Reply
John Miller Posted: 4/10/2019
I did the replacement and when I put it back together, I forgot to add water to the basket. Within seconds I smelled burning. I opened the basket area, and smoke came out. The seal has failed and water is coming out the bottom. Is it because of the dry start or did I do something wrong on the installation?Reply
InyoPools Product Specialist Robert M. Posted: 4/10/2019
Thee pump running dry caused the seal to fail. Installing the seal incorrectly wouldn't have caused the pump to smoke.Reply

I absolutely cannot get the white ceramic seal with rubber ring to fit in. Seems like everyone else is not having a problem but mine is too tight to even start in the cavity. Why is mine not fitting?Reply
InyoPools Product Specialist Robert M. Posted: 2/6/2019
Try wetting the rubber around the ceramic with water. That usually helps slide it into place. If that doesn't work, let us know the model of the pump and the part number of the shaft seal.Reply
Eddie Posted: 2/6/2019
Tried water, did not work. I placed the rubber seal part in the cavity first and then froze the ceramic part in my freezer for an hour, for contraction. After removing it from the freezer it slipped right in the rubber seal already in the cavity. No force was needed. Piece of cake when using that method.Reply
Edison Marshall Posted: 2/4/2019
Whoa, I messed up....I was careful not to touch the white ceramic side, but not so with the seal that meets up with it. What can I do? I have not replaced the wet end as of yet.... thxReply
InyoPools Product Specialist Robert M. Posted: 2/4/2019
Hello Edison - Wipe off the seal the best you can. It should be ok.Reply

I installed a brand new motor Hayward Tristar motor HP1.85 SP3200EE. When hooked up and turned it on, it hummed. What would be the problem. Any recommendations please. TJonesReply
InyoPools Product Specialist Matt S. Posted: 12/4/2018
Hello Teresa - a humming pool pump motor that is not turning is a common sign of a bad capacitor. Testing for a bad pump motor capacitor is relatively easy. If the capacitor checks out, then you may have a bad phase winding. I would start troubleshooting the capacitor and move on from there.Reply

Which motor will be compatible for my pump the pump I do have. SP3210Z2BER, PART#7-K56AA13A04-05 SERIAL#11213J2, FRAME#Y56Y, TYPE CXCP,HP 1.0/.12,VOLT 208-230,AMPS SF 8.5/1.5,RPM 3450/1725, HP 1.85 , CODE N, INSUL CLASS F, ENG/OD,AMB /C FFORM KJM. I am having a hard time finding this pump or compatible one TJonesReply
InyoPools Product Specialist Robert M. Posted: 1/2/2019
Hello Tereasa - It looks like you have a 1HP 2-speed Hayward Tri-Star pump. The replacement motor is part number SPX3210Z2BER. We recommend replacing the shaft seal when you replace the motor. The shaft seal is part number 5250-250.Reply
Tereasa Posted: 1/2/2019
What will be compatible to the SPX3210Z2BER/SP3210Z2BER ? hOW DO YOU LOCATE SPEED/ SINGLE OR 2 SPEED?Reply
InyoPools Product Specialist Robert M. Posted: 1/3/2019
The SPX3210Z2BER is the direct replacement for your current motor. Another option would be a variable speed motor. The variable speed model would be part number ECM27SQU.Reply
John Fitzpatrick Posted: 11/23/2018
I notice there was no impeller ring on this pump. I have an SP3007X10 Super II 1 HP. Should it have the impeller ring or not?Reply
InyoPools Product Specialist Robert M. Posted: 11/26/2018
Hello John - There should be an impeller ring on the Hayward Super II pump. You can view the part schematic on our Super II parts page. The impeller ring is key 7.Reply

Great guide, really helpful! Could you let me know which shaft seal I would require for a Hayward Super Pump being used on a Salt Pool?Reply
InyoPools Product Specialist Patrick P. Posted: 11/17/2018
You would require this Hayward Super Pump Salt Water Shaft Seal.Reply

Hello Lori - We have a guide titled "How to Replace the Governor on an A.O. Smith Motor". This would be the only content available that may help you reassemble the governor.Reply
Lori Posted: 7/15/2018
I used a wrench to hold around the governor to turn the impeller off and the springs fell off. We ended up taking off the governor, now in 4 pieces. Can you show me how to put it back on? Thanks!Reply

Takashi - No, water heated to 88-90 degrees would not damage your pump motor. It sounds like the bearings are going on your motor. This is usually due to the motor running dry for a period of time or failure to replace the shaft seal when a motor is replaced. The old shaft seal breaks down quickly and sprays the motor coils internally. If this is not the case, I’d talk to the supplier and see if they will replace the motor.Reply
Takashi Posted: 10/9/2017
Hi, I accidentally left my pool heater running for a week which heated the pool temperature to around 88-90 degrees. Now my pool motor makes a loud screeching noise. Do you think the water temperature ruin my motor? I just replaced the motor five months ago. Thank you.Reply
InyoPools Product Specialist Dennis R. Posted: 7/3/2017
Anonymous (shaft seal) - Thank you for your feedback. You are correct. The silver metal piece that is shown in the picture after the seal is removed, does have to be removed to allow the new metal piece to slide on. We do say this in the text, but it may be confusing with it not removed in the picture. I changed the picture.Reply
