Assuming the pump is at your working table, do the ff;
1.Unscrew the bolts holding the pump case.
2. Take the impeller and the mechanical seal off the
pump shaft.
3. Now you can take the motor off the pump by
unscrewing the bolts holding the motor and pump.
4. Then, you can dismantle the motor by unscrewing
the four long bolts holding it.
5. Take the back plate off and the centrifugal switch
on the shaft. Mark the original location.
6. Now, you can pull the rotor out, by a slight force
at the back plate side of the motor shaft. Note
that the front plate hold the bearing is bolted.
The front plate goes out with the rotor.
7, Now you can change the motor bearings.
To reassemble, the procedure is the reverse of what you just done. Send your e-mail for further assistance.

Does not matter on pool size, but on the filter tank size!
Follow Zeo's label instructions, as they may recommend a reduction of their product vs. Sand, say 80% of recommended sand amount. Good luck

I cannot start pumping. the pump runs but no water is circulating


I think you have spun the center out of your impeller. Disassemble your pump and replace the impeller if necessary. Also replace all seals while you are at it.

My Pentair Whisperflo pump is making a loud screeching noise while running. What could be the problem?


Inside the pump is a set of bearings that help the components of the motor run smoothly. When they become clogged with dirt and debris or wear down, your pool pump may get very noisy or stop working altogether. This high pitched squealing you are hearing is fairly consistent with bearing failure.
t might be best to have the motor seperated from the pump housing and take it to your local pool outlet or motor shop. Installation of the bearings will be a breeze for them and make sure that no damage is done to the shaft of while the new bearings are being installed. At this time, they can also inspect the motor and make sure that there are no other problems with the pool motor.
Also, you should ALWAYS, ALWAYS, ALWAYS replace the shaft seal whenever you take the pool pump motor apart. This will ensure a positive seal for the motor and minimize the opportunity for leaks to occur.

Replacing the bearings in your pool motor:

1. Turn off power to your pool pump by unplugging it from the power source or by turning off the circuit breaker. 2 Remove the plumbing from the pump. Take off the unions on the suction and discharge side using a wrench. Loosen the pool pump from the fitting holding it to the ground and move it to a comfortable area to work in. 3 Remove the housing from the pool pump and separate it from the motor. Look at the owner's manual for your pump to see the specifics on how to remove the pool pump housing, since each model is different. Usually you will need to loosen a bolt with a socket wrench and loosen the metal band that holds it in place. 4 Remove the four bolts that hold the pump together. These are located on the hand bell of the frame. Remove the motor end bells. 5 Pull out the motor armature to expose the ball bearings. Insert your ball bearing puller to pull out the old ball bearings. Inspect them for damage. Replace the old ball bearings with new ones after greasing them with bearing grease, and reassemble the pump.
To be honest with you, I don't even let our technicians replace the bearings in the field anymore. It is a little difficult and really, how many people have a "ball bearing puller" laying around their house.

*Please note, this should ONLY be attempted if you are comfortable with the instructions and taking apart the pump, have the necessary parts and tools to make the repair, and are familiar with ensuring that everything is back together properly!

How do you remove the impeller and mechanical seal off the pump shaft? I am wanting to change the main bearing that sits inside the motor housing of a Onga pool pump PPP750 model.


The impeller is screwed on to the shaft, you need to pull the cover off the end of the motor opposite the pump so you can hold the shaft to keep it from turning. The impeller should unscrew with just hand pressure, most are a standare SAE thread and turn counterclockwise to remove. Hope this helps.

I have a Sta-Rite Max-E-Glas II (1.5hp) Pool pump and a Hayward Navigator sweep. The sweep was working then stopped. Pulled it apart found bad bearings replaced them. Ran sweep again worked at first...


Is the pump leaking water? If you lost the prime or are having trouble priming then there would be an air leak somewhere on the suction side of the pump. Poor suction would interfere with the sweep. One way to ell if the pump or suction line(s) are leaking is to examine the inlet basket once the pump is primed. Any air left in there after a few minutes of operation once primed would indicate a leak in the suction/pump.

Your Onga Pool pump was running dry causing the
impeller to melt down and stick to the pump case.
You have to remove the impeller, and the only way
to take it off by using the heat gun to melt the stucked plastic impeller. Or by forcing it off slowly, cutting the impeller using hacksaw, taking care of the mechanical seal and the motor shaft not to bend it. Afterwhich you can replace the impeller, and assemble the Onga pump/motor. Then, you can
install the Onga pump back to its location. Just
send you e-mail for further assistance. God bless
you.

Pool pump problem


Possibly you picked up something that wrapped itself around the impeller of the pump. Pull out the pre-strainer basket located just before the pump and get a mirror and look inside the intake opening for the pump to see if there is any obstruction. The pump body may have to be taken apart to remove what's there. If nothing can be found, the next thing would be bad bearings. That would require a new pump, unless you think you have the savvy to replace them.
