For an impeller really stuck on the motor shaft you need to pull the motor thru-bolts and remove the rotor with the pump still attached from the stator. Lock the rotor in a vice and turn the impeller off with a large set of channel locks or a large strap wrench.

I have new impeller & seals for pb4-60 booster pump and need to know the orientation of ceramic/rubber seal should be inserted into impeller - rubber lip toward or away from threaded brass wijidigit?


Rubber toward the impeller,so when you screw the impeller back on the ceramic ant the graphite on the other half face each other. This is so the graphite wears smooth against the ceramic.

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 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. 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

Covering for screw to repair seal with spring. how to remove covering? the screw holds the plate that moves counter clockwise direction.


I'm not sure what your asking, but you remove the six bolts around the body of the pump then pull the halves apart. Most of these have a small disc at the back of the motor you can pry off with a small screw driver. The shaft under this will be flat on two sides and you can hold this with an adjustable wrench. While holding this then you can spin the impeller off and find the seal underneath. At this point remove the four bolts going into the front of the motor and remove the flange and simply knock the seal out with a screwdriver form the back. The other half you can pop out of the impeller and set back in with a small amount of lube. To set the other half you will need a 1" PVC coupling. This will fit nicely over the flange of the new 1000 seal. Put a small amount of silicone caulk on the rim of the seal and tap the coupling to drive it into the pump flange nice and even. Reassemble the pump but be sure to just hand tighten the impeller.
I hope this was what you were looking for and good luck.

How do you change the shaft seal on a polaris pb4-60 pump?


BE CAREFUL YOU CAN BREAK THE SEAL PLATE BY OVER INSTALLING THE #1000 SEAL , TAKE 6 BOLTS OUT UNSCREW IMPELLER THE TAKE THE 4 BOLTS THAT HOLD THE SEAL PLATE TO THE MOTOR, KNOCK OUT OLD SEAL FROM SEAL PLATE USE SOCKET THAT FIT OVER SEAL. I USE A 1 1/4 SOCKET. THEN REPLACE CERAMIC IN IMPELLER (READ INSTRUCTIONS WITH SEAL) OR TAKE IT TO YOUR LOCAL POOL PUMP MOTOR REPAIR GUY.. HAVE HIM DO IT . $ AROUND 40.00

Do you have an exploded view showing how the ceramic and spring go on?


The ceramic goes rubber side first into the back of the impeller. The spring piece gets pressed into the seal plate. I will usually just use a 1" PVC coulping and lightly tap into the seal plate with that. But sorry I don't have any pictures to send but you should get instructions with the new seal in the box. You should end up with ceramic against graphite when your done.

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.

I have a Polaris PB4-60 Booster Pump with a leaking seal. I have removed the Volute and removed the 4 bolts that hold the bracket to the motor. How do I remove the impeller? At the store they told me it...


You need to lock the other end of the motor shaft and then spin off the impeller. If you would like a quote on the replacement seal, contact us at www.arrowpools.net

Polaris PB-4 leaking from bracket area


I have a similar problem. The guy at the pool supply sold me a cup/spring assembly that seals between the impeller and the rear bracket. He says it is fairly straightforward to replace, but you must secure the drive shaft from turning buy popping off the rear cover on the motor (small round cover) and hold the shaft with something like pliers. I am first going to try to hold it in front of the motor at the bracket area. This needs to be held still to unscrew the impeller from the shaft. I am going to work on it today. We'll see how it goes. $12.50 part vs. $150 service call....
