Changing My Pump's Shaft Seal

[mas985]

The vegetable oil he shows is only used to help seat the seal and it should only be used on the rubber piece. But I have never had to use a lubricant on the rubber part to seat the seal. I have seen other seal videos recommending other types of lubricant for the rubber so I think it is a SOP in the industry. Another trick to keep the seal clean is to lube the housing instead of the rubber.

Anyway as to your issues:

1) The impeller will normally stay on by itself without an impeller screw but the parts diagram shows one so it should have one. Parts

2&3) Sometimes that can be a real PITA but a strap wrench is the right tool for the job.

4) There should be 4 screws that hold on the rear of motor to the motor housing. If you pull on the back of the motor, does it separate from the housing? I would try to find some screws to fit.

Thanks! Much appreciated.
I will order an impeller screw if I ever have to open the pump again (hopefully never).
Since I can't find parts for this motor, I wouldn't where to start to find such screws. Perhaps I'll ask Hayward to send me a set when I complain about the missing impeller screw.

The threads that these screws would go in to would be in the plate all the way at the other end of the motor housing - the one that bolts to the pump housing. You'd have to take the pump apart again and remove the front motor plate in order to see the threads. They would be on the inside face of the plate. The screws or bolts should be almost as long as the motor itself. You could probably Google the motor by its part number and get a parts list that would include the screws. Also try a pool pump motor replacement website. Many of them will have a "motor finder" where you can cross reference your motor to a generic number. You could then search for parts for that. If they're just missing and you can get them, you may be able to just install them. If somebody broke them off, you'll have to take it all apart to get to that front plate and try to extract the broken off pieces. I would expect that to be a significant challenge. I guess you could always replace the plate. At some point a new motor would be more economical.

It's very expensive pump and I'm quite annoyed. But... it's almost two years old and I'll have a very hard time making any kind of claim.

Maybe some silver tape and double bubble.

Yes, I can imagine. Actually some of that foil tape used for heat/AC ducts would at least keep it together for the rest of your season; although, it seems to be holding together by itself. Perhaps then you could get it apart enough and get it to a motor repair shop. A little $$ may prevent a larger loss. I suppose it can't hurt to contact Hayward and complain. They probably put that one together on Friday afternoon. Good luck.
