should I replace the seal every time I replace the motor?

Yes we suggest replacing the shaft seal whenever you replace your motor as the old seal sometimes does not mate up properly with the new motor. Also the warranty on the motor is voided is there is leaking to due the seal.

It will depend on the model of your pump, not your motor. The motor can go to several different model pumps, so would need to know the model of your pump to determine the correct shaft seal.

While replacing the pool motor thought it was best to replace the seals while the pump was apart. No problem, perfect fit. New seals and bearings got the motor up and running perfectly and I did it myself.

Pump Shaft Seal Heavy Duty (Saltwater Pools) - PS-3867

remove motor from pump per video on inyo. Open pump, remove seal carefully. placing where you will know proper orientation to place new seal. Use the non petroleum shaft lube. (Lubricant 1CC Pillow Pack - LUBE-PP), as new seal is tight and may not let pump shaft rotate without it. It is an easy operation but you really need to watch the video.

Replacing old noisy motor

Written on 10/29/2020 by Guest

When replacing the motor you need to also replace the seal. My pump motor was making a loud screechy noise indicating worn bearings. Also the pump seal was leaking causing water to drip below the pump shaft where it connects to the motor. This leaky seal may have caused the bearing failure.

I upgraded to the tougher salt water seal since my pool is salt water. The previous seal was the “normal” duty seal and had leaked possibly resulting in the motor bearings going bad prematurely.

After disassembly, I pushed out the old portion of the seal from the Pump backing plate Then pushed the new portion in using a lint free cloth to be sure to keep the ceramic surface of the seal clean.

Reattached backing plate to new motor and then pushed on the impeller side of the seal again not touching the ceramic surface. Be sure to put the seal on so that ceramic surfaces of both sides are facing each other.

Screwed on the impeller, reassembled the pump and fired it up. No leaks detected.

Leaking shaft seal

Written on 8/1/2018 by Guest

Existing shaft seal was leaking (salt water pool) and found out my previous repair guy did not put in a heavy duty seal for salt water. Ordered the replacement from INYO and had it here in a couple of days. Disconnected the power from the motor, removed the pump faceplate and housing from the motor. Easily removed the diffuser and impeller following the instructional INYO video and replaced the seal shaft. Put everything back together in reverse order and fixed the leak.
