Great videos Roger! I have an Armstrong 4380 vertical mount where the motor has failed(open winding) . This will be my first attempt on replacing a closed coupled pump motor. I assume it's best practice to order the seal kit and replace them any time you open up the pump? Thanks !
Thank you for sharing the video. at 4:30, about the sleeve, you mentioned the bottom part will be corroded, but why? I thought that the bottom part was sealed by stationary seal and rotating seal and separating from liquid, and the top part is surrounded by liquid. Could you please correct me? Thanks,
I've always been told to NEVER touch the faces of their seal. Is this true? If so, what's the best way to clean off the seat faces after they've been contaminated? For whatever reason, we have two motors for a pool who's seals keep leaking in less that three months. Not sure if it's the sand that cycles through, too high a chlorine level or what.
its a no touch on chillers and things that spin very fast .. pumps typically are lower RPM and have some water to 'lube' them if you wipe the surface with a clean cloth ( your shirt maybe? ) it should be fine . you don't want any grit on the faces. Pool pumps can cavitate and/or see some grit. you should look at how they are failing ..is it the sealing faces or the elastic parts that are deteriorating .. if its the sealing faces then its grit .. if its the soft parts its usually chemicals
when replacing a motor, what information is needed when looking up what seal kit to install? how do I know which seal kit to buy? shaft diameter...etc?
the seal kit is chosen on the basis of the pump .. you should contact the pump manufactured with the pump model #, horse power and sr# and get the seal info from them .. there are LOT of variables... you also could have success by taking the old seal to a pump repair shop .. they may be able to duplicate it

yes it is best practice ... I think that in the last several years Armstrong started using lock tight instead of a sweat fit sleeve

gets wet when they leak
Fantastic tutorial. Thank you!
You're very welcome!

great info!!! amazing presentation... thanks for the info.
Great Video. It's good that I can find this stuff on here.
The resemblance to Larry Boy is amazing before you took off the pump.
Great Info!!
