How do you assemble a Hayward pool pump
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!
