bad capacitor or motor or blockage in impeller

Check the basket at the skimmer and the one on the pump and make sure they are clear. If you have a pressure gauge on your filter does it read higher or lower than normal? If it is higher that would indicate a dirty filter and needs to be taken apart and cleaned or backwashed. If it reads lower than normal the problem may be a clogged impeller, where debris has gotten past the pump basket.

check wiring on side of motor if 120 volts needed to change wiring on inside back cover

I suspect corrosion in the bearings, which means probably in the motor as well. If it runs nonetheless I'd just keep using it until it stops as once it gets to that stage it isn't economical to repair.

CHECK TO SEE IF THE RECEIVER HOUSING HAS A CRACK ALONG THE THREADS IF NOT TRY MORE WRAPS OF TEFLON TAPE

Find this part at your local pool supply store. A plumbing supply is another source - be warned - if someone offers to make this "O" ring for you --- it will be about $100.00.

This is a standard part at a pool supply place.

PAC-FAB / Pentair Dynamo pool pump parts, Discount parts for PAC-FAB Dynamo pumps

This site shows a separate part for the strainer body, but I'm not sure it is separate.
Call them with your model number and they can tell you if it unscrews and sell you the repair part that you need.
Worse case, you might have to see if you can remove the entire pump casing and purchase that.

I think you haved spun the impeller ... check it out ...

Dynamo... | Answered on Oct 13, 2010


This is from one of my previous posts, may be some extra steps, but should cover what you need... Turn off the electric first. Now split the pump in two by removing the large clamp or 4-6 bolts holding the two halves together. (not the 4 bolts holding the motor to seal plate, but the the bolts holding the seal plate to the seal plate housing). Once you remove the clamp or bolts, the motor with seal plate, diffuser, and Impeller can all be pulled back away from the pump. Then disconnect the electrical from the motor and you can pull the motor with the seal plate, and impeller all the way out and work on it. To get to the impeller, you need to remove the diffuser (plastic housing that goes around the impeller) usually by a series of 3 to 6 small screws. 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 tail piece 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 the thermal overload switch, or removing the capacitor for even easier access. Once you've locked the shaft, you can just unscrew impeller. If the impeller has a bolt or screw in the middle remove that first. this screw will 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 (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 to replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white ceramic, and black graphite surfaces 100% free of any dirt, grease, etc while working with them. Installation is pretty much just the reverse. Install half the seal into the seal plate. Install the seal plate onto motor and bolt into place. Install other half of seal onto shaft. Screw impeller onto shaft and install screw (if one was there to start with) in center of impeller (reverse thread). install diffuser over impeller make sure it is centered and doesn't rub the impeller hub. Install new diffuser and valute o-rings. Hookup wiring before re-attaching to rest of pump. Clamp or bolt back together. Pour plenty of water into pot to prime and flip the motor on for a sec or two. Pour some more water. Install pot lid. You should be good to go. Keep in mind there are many different pumps and some variations to the above instructions, but the above should cover most situations. Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave a good thumb rating if you found this helpful. Thanks, and good Luck!

After you have the pump broken down. Check for a screw in the center of the impeller. If it has one then you will need to remove it. This will be a left handed screw. If that is done then you will need to remove the back of the motor or the small center plate on the back. Then the shaft will accept a wrench to hold it with. Then you should be able to unscrew the impeller with water pump pliers or a large basin wrench. The brass threads on the impeller will kind of stick to the steel of the shaft so it is just a matter of breaking it free, then it will spin easily.
I usually put a screwdriver in the left side of the impeller and give it a sharp smack downward with a hammer.
There are two methods, good luck.

You need to check and see if the shaft going from the motor to the pump is turning. You can do this by adding a small piece of white electrical tape to the shaft (while the motor is unplugged and not running or you could injure yourself). If the shaft is turning then the pump is loosing prime and will have to be replaced. If the shaft is not turning, it could be the bearings are locked up. You could try oiling the bearings. They are located on either side of the motor. Not too much, or you could damage the motor. If this works then you should probably budget for a replacement next year as this is usually only a temporary fix. If it doesn't loosen it up then you will have to replace the motor. I found it cheaper to replace the pump and motor as a unit from the pool supply store rather than trying to purchase a new motor from a motor supply store. Check prices before making your purchase. Hope this helps.

I'm assuming you mean whe you thread the strainer basket pot into the pump and tighten it it ends up being 90 degrees off center? That means you cannot turn it and additional 270 degree. Unthread and wrap multiplul wraps of teflon tape onto threads. Then I'd add lightly add some pipe dope. Tighten the assembly up, but stop when it is snug and aligned. The combination tape and dope should keep it from leaking, but remember this would be a suction leak, so check carefully
