I put it all back together and it still made the same noise and did not pump at all.

The power source is a little jacked up as well as the pump runs for a while then shuts off. This is being addressed today but what do you think is wrong with the motor?

Thanks!
I am new to the site but deal with pumps daily with my job. Make sure that all your valves are open so that water can pump through. Under no circumstances should a pump be run without liquid...unless designed for it. The reason for the smoke was most likely the seal kit creating friction. does it sound like you are trying to pump gravel? or maybe marbles? if so you may not have enough back pressure on the suction side of the pump. this creates air in the eye of the impeller which contain enough heat to create steam, when it creates steam is is a small explosion inside the pump thus the gravel sounds. when that happens you can most definitely ruin your impeller and volute casing...a pitting will happen.

Also make sure the entire inside of the pump is filled with water...if air gets inside there, then it creates a buffer to where water will not be able to pass.

Noisy pool pump?


HI first off it may be more than bearings, you need to get this to your local pool pump repair guy with free motor testing asap . it is not going to get better it will not fix its self . and should cost about 75.00 to fix the motor and the shaft seal.

DO NOT try to take the impeller off ! this little stunt can cost you big and take what was a cheap FIX into a real bummer $$$ find out what kind of PUMP and motor you have and call for help on how to remove the motor with the seal plate attached ?

BEARINGS are not easy to replace and require the proper tools to do it right I press the bearings on. (just like the factory does). not with a hammer this damages the bearing and considerably reduce the motors life.

TIP - TRICK is to keep a eye out for the wet spot under the pump, this is a sign of shaft seal FAILURE and needs to be repaired asap this is a 20.00 fix and will save your motor from getting water in it., witch is more than likely what happened to your motor , shaft seals are good for 3-6 years Ive had them last up to 8 yrs but at this time the motor needs a tune up or rebuilt.
thats the difference between beating the bearing on with a hammer or using a $6000.00 press to gently ease the bearing onto the rotor of your motor.
TIP - TRICK #2 never use thread tape on a plastic pump !

REMEMBER
A CLEAN POOL IS A SAFER POOL

1# do not over install bearings nor under install ,do not beat on the outer race of bearing, do not damage blue or red seal of bearing !

2# USE A VACUUM CLEANER TO CLEAN OUT THE INSIDE OF THE MOTOR.. CAREFULLY

3# bearing can be removed with bearing puller and installed with a small piece of pipe or a pipe nipple.

3# threaded rod can be used in place of long bolts, you may need to drill and tap the silver stuff is used on bolts , so in the future the motor will come apart with ease

4# install new shaft seal in seal plate (never use old shaft seal) prime filter basket of pump with water place lid back on filter basket , start pump up and make sure it flowing good


5# remember to prime the pump

6# your done ! keep a eye on it if you ever run it dry or starve the pump for water YOU NEED TO CHANGE THE SHAFT SEAL SOON !


7# remember to prime the pump after any repair !

I went to check your link but I think your website is offline.

Pool pumps produce sounds as quiet as the turtle or as loud as a roaring lion.

Noisy pool pump?


My pool pipe broke open and the water pumped out - about 2 feet worth and the entire hot tub before we shut the system down. I just had the pipes fixed, turned it back on and now the motor is whining. Is there anything i can do to stop the noise or at least tone it down? WD-40?? Grease?? Something?? The water was pouring all over the pump.. probably didn't help...

The bearings are sealed so oiling or greasing wont help. You can replace the motor or install new bearings. To replace the bearings you'd need a puller and also a driver.........or take it to a shop that works on motors.

Noisy pool pump?


in the meantime, the pump is still pumping so would I damage it further to run it or should I just take it in right away? Other than the extra noise, it seems to be pumping like mad. Also, the filter pressure is slightly over 30 lbs and it has new filter cartridges in it .. that seem ok or a little high? If you can help, thanks!

BTW, the pump is Hayward Northstar AO Smith Century 1051. 2hp

Noisy pool pump?


Nice pump... I've seen pumps that get a whine/ring due to bearings and run fine for years, others start going bad and are dead in 2 days......? You can damage the windings inside of the motor if the bad bearing is causing alot of heat that may or may not be the case with your pump, but you could check the motor by touching it with your hand.....it should be warm but you should be able hold your hand on it and not get burned.

Are you capable enough to unwire/rewire the motor and cut and glue the pvc? If not then I would say that replacing the bearings is not an option because most pool companies dont do that in the field....very few inhouse servive drop-off's will change bearings at all. You will need to find a motor shop...DO NOT let Leslies work on your equipment. If you do this you could save yourself $300-$500.

Or you could run it and see how it goes you may luck out and have it last for years. When it dies you call a pool guy who installs a new motor and seal while your at work, and you pay $500-$700.

This repair can be cheap or easy but not both

With your filter 30psi is a on the high side, unless your pump/filter 40+ feet from the pool side. Make sure that all of your return valves are open, make sure the filter tank is bleed of air and if need be pull the cartridges and hose them off.
Also most presure gauges used on pools are very cheap and of poor quality......so it may be a bad gauge.

Hi

Bearings inside pool pumps are "sealed" bearings not "shielded" like the bigger pumps therefore you cannot grease them.

You will need to change the motor bearings, it will take an hour or two.

Let me know if you need more help or check out my TV section to watch us change bearings, its easy of you are handy.

We don't mind teaching

Hi

I would rebuild the pump before it gets damaged further,

When the motor bearings start to go bad inside of the pump they start to vibrate and that can start to wear out the "inner race" inside the motor "end bell"....you do do not what that to happen,

Let me know if you need more help or have any questions,

Joseph
