My Hayward super pump is leaking water where the two large sections come together with six 9/16 bolts at the very top. I replaced the large flat rubber seal and even tried silicone on the faces that come together. Maybe the faces are warped? Is there any sealent or other ideas to stop the leak? Thank you, Steve

Shaft seal has failed. Replace it immediately or water will get into the motor and the motor will have to be replaced. The leaking is there by design to let you know when its time to replace the seal.

The leak is an indicator the shaft seal has failed. It leaks by design to let you know to replace the seal before water gets into the motor and ruins it. Replace the seal right away.

You may have sized the shaft seal wrong or the seal may be installed incorrectly. Make sure you have the correct seal and that the shaft is not wobbling.

YOU WILL NEED A NEW IMPELLER SPX3010C SUPER HAS 4 BOLTS OR A SPX261OC SUPER 2 HAS 6 BOLTS. JUST TAKE THESE BOLTS OUT AND THE IMPELLER SCREWS OFF TO THE LEFT, CLEAN UP THE TREADS. USE A NEW 201 SHAFT SEAL. AND ON THE MOTOR PICTURED THE SHAFT CAN BE HELD AT THE BACK OF THE MOTOR TO SCREW ON THE NEW IMPELLER.. PUT IT ALL BACK TOGETHER ,PRIME THE PUMP WITH ABOUT 4 GALLONS OF WATER. RUN IT AND WATCH FOR LEAKS .. NO LEAKS ? YOU GOOD TO GO ! ..

Remove the six bolts that hold it together. Pull the half''s apart then pull the diffuser off the front of the back half that is still connected to the motor. Look in the center of the impeller. If their is a screw there it will be a left hand screw, remove it. Now you need to unscrew the impeller. Open the back of the motor and get to the end of the motor shaft. Their are two kinds of motors so use a wrench that will fit yours to hold the shaft and use water pump pliers (Channel locks) to grab the impeller and unscrew. This will come hard at first once unstuck it will just spin off. Pull the rear seal plate off and the back plate will four bolts to remove. With that your done.
When you first pull the six bolts and open the pump you can pull the wires and bring the whole thing to a motor shop or pool store and they will usually just charge for the motor and parts and do most of it there for you.

Most likely leaking from either the shaft seal, or the valute seal (big seal plate o-ring). When you replaced the motor you should have also replaced the shaft seal. If not go back and do that whether it's leaking or not. If you get your head down and look at the bottom of the pump while it's running you should be able to see the water coming from the joint between the seal plate, and the seal plate housing, or just behind that from the bottom of the motor probably from the vent holes in the motor housing. If it's coming from the motor then the shaft seal is leaking, and the water is traveling along the shaft and out the bottom of the motor. This will eventually get into the motor and seize up the bearings. If it's coming from the valute seal, then you need to either replace or re-seat the seal. As a general rule you should always replace the shaft seal, and diffuser and seal plate o-rings when you replace the motor or split the seal. I'm not as familiar with the 2 speed hayward super 2, but the standard super 2's have a small ribbon seal, often called a rubber band. They are infamous for going bad especially after pulling the pump apart.

Here is a copy of the users manual for these pool filters. It has detailed illustrations about how the filter should be put together.

Pull the six bolts on the back of the pump and pull the motor and pump housing back. remove the difuser and try spinning the impeller. If it wont spin you may need a new motor. If you pull the wires. You can find a motor shop in your phone book and they can rebuild it for you usually for about 100 bucks. Or replace it with new for a lot cheaper than what your talking. Good luck.

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.

normally this is not a crack in the housing. It is usually a shaft seal.
