Is it a mistake to not replace pool pump bearings?


If they are noisy Yes also replacement of the pump seal is very important. We recomend replacement of the seal every 2 years if pumps is used to vacuum pool.

Help! Just opened my pool and the pump/motor (which is only 2 years old) is very noisy. Sounds like it could be the bearings. Do call someone to the house, disconnect and take to a repair shop, ord


Disassemble the pump to the point where you can see the whole impeller. Then turn the power back on to verify that it is the bearings, and not trapped debris causing the noise. If it is the bearings the short answer is to replace the motor.

Bearing failure is usually related to a leak at the pump seal. This results from either a faulty seal installation, or the pump running excessively hot (from running w/o water).

When replacing the motor carefully examine the seal plate (where the seal is set) front and back for any cracks or deformity. If the new seal doesn't set exactly, it will leak.

My Tsurumi 50PMU2.1S runs very slow. I have replaced all beatings and seal could it be the capacitor? Rob


Hi Rob,

If it was the capacitor the pump should not start at all but if you know a electrician there is a way to verify if the capacitor is charge and/or recharge it with a ''UF'' tester

Check also if the power cable is damage or maybe was damage before and someone fix it with duck tape or anything else, and if the electric plug is very old and rusty, if so replace with a new one,

Other then that will have to check the motor and probably have to rebuilt it or replace it, when you changed the bearing did you notice any burn or damage part on the Stator?


Have a nice day

Motor is very noisy


Noisy motor indicates bearings on the shaft are going bad. This happens when you have a shaft seal leak and the leaking water is getting to the bearings. Sounds like you need to replace shaft seal and set of shaft bearings. Easy fix is to replace the motor only for about $150.00 for motor replacement. Around $40.00 for seal and bearings and some of your time.

Noisy spinning and water leak


The noisy spinning on this model washer is usually the drain pump bearing going bad which could also be a possible cause of the leak. Unplug the washer, Tilt your washer back and rest it against the wall. Remove the belt and manually turn the drain pump pulley, if it is hard to turn either way or is grinding or noisy it will need to be replaced. The leak is a little harder to find. Remove the front bottom and top panels, run the washer, stay back with a flashlight and look where the leak is. If the drain pump is bad it is likely leaking. Next check the center, bottom of the tub for leaks, if the leak is her it is likely the cause of both problems. The tub seal is leaking and has ruined the tub bearing. The tub seals and bearing would need to be replaced. Very involved job, and I would suggest you call a servicer with the expensive tools and knowledge to do the job. There is also a bearing on the bottom of the transmission which could be noisy but would not cause a leak. Hope it is only your drain pump.
Please rate this post. Thank You

Pressurised water pump is noisy during operation. Sounds to me could be a bearing. How do I test ?


You are definitely right. Its the motor bearing. You can
see it just as soon as you dismantle the motor and the
pump. We cannot test it, but it can be heard. There's no
other part in a pump that could be noisy due to wear and
tear.

When on spin cycle makes noise & water comes out under machine. How do you take off back of machine to get to the pump area ?


Possible drum bearing problem , seals leak into bearing chamber and beyond , bearings seize and become noisy. Pumps get noisy but rarely leak.
