I have a Yamaha yz 125 2003 and there is water leaking out the bottom through a small whole and was wondering why it is doing that as it has just started doing it recently


This is telling you your oil and water seal need replacing ASAP do not ride until fixed as you will seize bottom end guaranteed !
there is small seal each side of your water pump impeller when you take the impeller out replace both even if only one needs doing as you will be going back to replace the one left soon after as they always go together..
Most people would not do this repair without replacing the impeller as well - usually the impeller starts to wear groves where it spins inside the seals then damages the seals So you get the theory behind replacing the whole lot as old impeller can damage your new seals
The seep hole is designed to give you warning of burst seal before its way to late as without the seep hole leak you would have no idea you are leaking coolant into the motor
You can do your self its a bit of work but not complicated - if you do your self don't forget to change your engine oil couple of times after first few rides reduce any risk of having coolant inside it where it should not be
good luck regards Jamie

I have a proline 1.5hp pump need to replace the shaft seal. I can't seem to get the plastic impeller off. We use a screwdriver to hold the shaft screw and try to turn the impeller counter clockwise...


Keep trying - It is stuck and will likely break but you have to remove it to change the seal. It is not uncommon to need to replace the impeller when the seal fails since the water gets behind the impeller shaft and rusts the metal causing the impeller to bind. If you still cannot get it free pull the motor thru-bolts and lock the rotor once removed from the motor in a vice. Use a large pair of channel locks to break the impeller free...replace it if necessary.

Winding noise with some water leaking from the motor seal. Water still flowing but sounds laborous.


The shaft seal more likely than not needs to be replaced. If your shaft seal has been leaking for any length of time, the bearings could be damaged and this should be replaced. The whisperflow uses a PS1000 shaft seal and is fairly easy to replace (most seals available online or at most swimming pool retail stores). It is best advised not to run the pump until you have had this inspected by a licensed pool technician or have changed out the seal.

1) Make sure breaker/power to pump is off. 2) Remove the six bolts holding the wet end to the seal plate. 3) Remove the diffuser to expose the impeller. 4) Remove the screw in the middle of the impeller by turning clockwise (left hand threads). 5) Remove the dust cap at the rear of the motor and use a wrench to hold the shaft while you remove the impeller by turning counterclockwise. 6) Once the impeller is off, remove the four bolts holding the seal plate to the motor. 7) Press the old seal out of the seal plate and clean it thoroughly. Remove the ceramic part of the seal from the impeller and clean it thoroughly as well. 8) Apply a thin coat of lube (I prefer Magic Lube or Lube Tube) to the seal plate and impeller where the new seal will go. 9) Remove the new PS1000 shaft seal from the box (being careful *NOT* to touch the ceramic or carbon face with your fingers), press the metal part into the seal plate carefully, try not to bend the metal and make sure its completely seated against the seal plate. 10) You can now install the seal plate back onto the motor and secure with four bolts. Press the ceramic part into the impeller, use cardboard or paper between your fingers and the ceramic face. 11) Once you have seated the seal into the impeller, hold the motor shaft and thread the impeller on until snug, then reinstall the stainless screw, remember it is left hand thread so you'll have to turn it counterclockwise. 12) Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.
Check the pump for operation and you should be good to go!

Pool sweep pump stuck and will not turn.Binding on impeller to rubber seal.How to disassemble remove impeller and seal.


Sounds like maybe your motor bearing are going bad, or have already seized up. When you say "rubber seal" are you referring to the rubber portion of the shaft seal? Either way, to remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tailpiece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. If the bearings are seized up then you'll have to replace the motor, or have it rebuilt.

How do I remove the pb460 booster pump in order to install the new one? Does the water have to be turned off from the pool?


You are trying to remove the pump so you can replace the impeller correct?
To remove the impeller you do not need to remove the whole pump. Turn off the electric first. Then just remove the several bolts and separate the back half from the front. Then disconnect the electrical from the motor and your can pull the motor with the seal plate, and impeller all the way out and work on it. To remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tailpiece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should be reverse thread so make sure you don't turn the wrong way and break or strip.

If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. Make sure replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white and black ceramic surfaces 100% free of any dirt, grease, etc while working with them

How do you replace the rear seal on a aqua flo xp2


You will need to get access to the impeller, then unscrew it counter clockwise. You will have to hold the shaft of the motor to unscrew the impeller. You can gain access to the shaft by popping off a little round cover on the back of the motor, you should see a slot in the motor shaft. Once you get the impeller off, unscrew the thru-bolts. The housing should pull right off. From there you can pop out the seal half that is in the housing and replace it - the other half of the seal is on the impeller. These 2 pieces come with the new seal. When you put the housing seal half back in use some silicone around it. The impeller end just pushes on. Link to Aqua Flo XP2 Diagram

1hp whisperflow pump, seal change. How?


Make sure breaker/power to pump is off. Remove the six bolts holding the wet end to the seal plate. Remove the diffuser to expose the impeller. Remove the screw in the middle of the impeller by turning clockwise (left hand threads). Remove the dust cap at the rear of the motor and use a wrench to hold the shaft while you remove the impeller by turning counterclockwise. Once the impeller is off, remove the four bolts holding the seal plate to the motor. Press the old seal out of the seal plate and clean it thoroughly. Remove the ceramic part of the seal from the impeller and clean it thoroughly as well. Apply a thin coat of lube to the seal plate and impeller where the new seal will go. Remove the new PS1000 shaft seal from the box (being careful not to touch the ceramic or carbon face with your fingers), press the metal part into the seal plate carefully, try not to bend the metal and make sure its completely seated against the seal plate. You can now install the seal plate back onto the motor and secure with four bolts. Press the ceramic part into the impeller, use cardboard or paper between your fingers and the ceramic face. Once you have seated the seal into the impeller, hold the motor shaft and thread the impeller on until snug, then reinstall the stainless screw, remember it is left hand thread so you'll have to turn it counterclockwise. Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.

It is a good idea to replace the tank o-ring when taking to pump apart, but if the o-rings are in good condition, just apply a light coat of lube and reuse them.

This is a general guide for replacing a seal, if you have trouble removing the impeller, you may need an impeller wrench and a tool to hold the motor shaft.

I hope this helps, if you have any specific questions, email me at mail@leisurepoolservice.com

Need instructions on how to replace seals


ok, I will try my best. First, make sure power is off to the pump. Then, remove the six bolts and nuts on the front (wet) end of the pump and expose the impeller. On the back of the motor, you will need to remove the small dust cap in the center. Underneath that dust cap should be the shaft that is slotted. You will need a large screwdriver to hold it from turning as you remove the impeller by turning it counter-clockwise. Once the impeller is off, remove the four bolts holding the seal-plate onto the motor. Once you have the seal plate off, press the old seal out by pushing from behind with a flat tip screwdriver. Once the (ceramic part) seal is out, clean the area where the seal seats very thoroughly and apply some silicone lubricant or even Vaseline to for a nice uniform coat to the area, don't leave any of it dry but don't glob it on either. Next, pull the carbon/spring part of the seal off of the impeller by twisting pulling it at the same time. Make sure all of the seal comes off including the rubber washer/o-ring. Apply a very small amount of lube to the impeller shaft where the new seal will go. Install the new seal onto the impeller, be careful not to touch the carbon face of the seal if you can help it. Slide the seal all the way onto the shaft until it bottoms out. Next, install the ceramic part of the seal into the seal plate, be careful not to touch the ceramic surface. Press it into place using some paper of cardboard from the box the new seal came in. Make sure it seats all the way down, inspect it from the back to make sure the seal is completely seated. Install the seal plate back on and torque the four bolts onto the motor. Thread the impeller onto the shaft until it bottoms out, hold the shaft and tighten the impeller lightly, no need to crank on it, snug is good. Check and lube all your o-rings and install the wet end back onto the seal plate. Reinstall the motor shaft dust cover and you should be back in business. Be sure to fill the pump with water before turning it on. You can usually do this by starting your filter pump first.
