How do you disassemble the seal plate from the motor on a craftsman pool pump. Are there Through bolts?

NOT tat bad, (first x2) shut breaker off next take off the stainless steel band, pull motor and seal plate back from plumbing portion use wrench on back of the shaft of the motor, impeller screws off to the left, take out 4 9/16 bolts that attach the motor to the seal plate, give seal plate a tug and it should separate from the motor. use new seals especially the shaft seal (the one w/the spring in it) and put it back together. tap on the SS band this allows it to evenly pull up around the tank body lastly FILL PUMP (prime) with water.
or search for your LOCAL POOL PUMP MOTOR REPAIR GUY. and ask about installing the motor on the seal plate.
I charge $20 and it includes the shaft seal (most pumps)

It depends which pump you have, on hayward super II you shut off the breaker, remove the rear motor cover, disconnect the electrical wires, then remove the 4 (9/16")bolts holding the motor to the "wet end" which is where the basket is. Now, pop off the diffuser, sometimes it stays in the wet end when you remove the motor. At the rear of the motor, use a 12mm wrench to hold the shaft, then unscrew the impeller (counter-clockwise) after removing the impeller, theres another plastic plate that lifts off, remove the plate, now there are 4 (9/16")bolts to remove in order to separate the motor from the seal plate. You have now broken down the pump. If you replace the motor, make sure to get a new seal as well (ps201)

It sounds like the seal has a death grip on the motor shaft. Pick up the seal plate so the motor is hanging beneath it. (watch your toes) Holding it about waist high let it drop and then snatch it back up again. Kinda like getting a pillow in its case. The motor should drop out.

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!

could be an obstruction in the impeller, or the bearings going out. You can split the pump in two be 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 and impeller and diffuser can all be pulled back away from the pump. You need to remove the diffuser (plastic housing that goes around the impeller) usually by a series of 3 to 6 small screws. Now you can easily try and spin the impeller and check for obstructions that might have bound it. If you do not see anything stuck in the impeller, then the noise is likely coming from the motor (probably the bearings) you can replace the motor, or have it rebuilt. if your not gunna rebuild it you can deal with it as long as the noise doesn't bother you and the motor is not getting too hot

If it is completely apart, I am guessing you were replacing the motor? Anyway, motor gets mounted to the mounting plate plate by way of four bolts through the mounting plate into the motor. There is an top and bottom to the mounting plate usually indicated on the plate. Next goes the seal plate, there is a top and a bottom as well, usually indicated on the plate, also there is a **** in the seal plate at the bottom, an opening so if the shaft seal leaks, the water has somewhere to go instead of to your motor to rust it out. There are no bolts for the seal plate, it is held in place by the impeller. You need to get a new shaft seal before you do all this (SPX1600Z2), any compitent pool company should have a bunch of them in stock. Shaft seal is two pieces. The white porcelin piece with a rubber gasket around it goes over the shaft and into the seal plate. It fits snug in the seal plate and does not touch the metal shaft of the motor. The other half of the shaft seal goes on the impeller. The side of the piece of the shaft seal that is all black, with no metal, does not bump up to the impeller, it eventually will touch the white porcelin that is now in the seal plate. That black part of the shaft seal that goes on the impeller is made of carbon and can break somewhat easily so don't bang it on anything. You have to wiggle that part of the shaft seal onto the impeller with a little elbow grease. Make sure it is seated all the way on the impeller. Now you can screw the impeller on the the motor shaft. The motor shaft will want to spin on ya so you have to take the back of the motor off and hold the shaft. Should be a 7/16 or 1/2 inch wrench depending on what motor you got. Snug the impeller up while holding your wrench on the shaft. Doesn't need to be a death grip, the motor will actually tighten the shaft seal more due to the direction that it spins. Now the seal plate should be imobile after you tightened the impeller on. You now put the diffuser on to the seal plate. It also has a top and a bottom usually indicated by some writing. The diffuser has little nobs on it (for lack of a better term) that correspond with female groves that accept the nobs located on the seal plate. It just sits there in those groves, no bolts of screws or anything. Lubricate the gasket on the pump housing before you slide everything back into it. And make sure there isn't any debris that's gonna pinch between the seal plate and the gasket. Slide the whole mechanism into the pump and the seal plate should meet flush with the rest of the pump and tighten to it by way of four bolts (9/16"). When sliding that in there you can take off the pump lid, remove the skimmer basket, reach through the whole and guide the diffuser to the hole. Get those four bolts well snug, but if you tighten too much they will start to recess into the housing which aint a huge deal but you don't really want to go too far down that road. I hope thats all understandable, maybe i went into too much detail but I have taken apart and put back together so many hayward pumps that I have learned all the little things that potentially go wrong......good luck!

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

depending on the pump you have, you'll need to remove the seal plate from the wet end and remove the impeller before you can remove the motor.

The thru-bolts hold it to the seal plate and the impeller is threaded onto the shaft.
