I get power and sound like it wants to spin but I havent fired it up in 1 year. do you think I should REPLACE or just open it up and see if anything it stuck? 881410 on May 23, 2011 at 10:39 pm Thank You Sir. Very helpful indeed, and the only useful video here on the subject of opening one of these pumps. Time saving, money saving, interesting and crystal clear – well done, and thanks again! nviersen on June 20, 2011 at 12:00 am you saved my butt!

You sure made it look easy on a brand new pump and impeller, maybe next time use a old worn out pump? MsGhostrider702 on March 18, 2012 at 11:02 pm Very helpful and easy. Thank you sir for the video you’re the man. dogfriend2010 on April 1, 2012 at 2:58 am Excellent! I just completed overhauling my pump. Had a couple of minor challenges not covered in the video – a ground wire, and the end cap on the motor was a little different, plus the usual stuck bolts you have on many projects, but I laughed out loud when the pump starting pushing water at 20 psi – up from 5 psi! Very accurate; I referred to it several times during the job. I now have the confidence to know that I can do this again – quicker! Thanks!!@! Scott Hamilton on May 12, 2012 at 5:02 pm There is a way to replace bearings inside of that motor as long as the through bolts all come out! twfromsd on May 18, 2012 at 5:18 pm Just overhauled my 10-year old pump utilizing this outstanding video. My end cap was a snap-in instead of a screw, and protruded past the shaft, so it couldn’t easily be gripped. Had to remove the (4) long bolts to back off the motor cover in order to grab the shaft with a wrench. As the impeller could not be spun off by hand, used channel locks to grab the small collar protruding from the impeller. Didn’t need much force as it is supposed to be hand tightened only, but wouldn’t budge initially. doug oz on May 22, 2012 at 5:24 am anyone know if my pump needs this? I just posted a video on youtube showing what my pump sounds like. Thanks mrsdeerocker on May 22, 2012 at 9:46 pm Quick question for you: If I only want to remove the diffuser in order to clean any debris off of the impeller–can I do this WITHOUT removing the impeller (thus not having to hold the shaft,e tc)–in other words I assume once the diffuser is off I can quickly wipe debris from impeller and put everything back together. GREAT video by the way–thank you–I hope to see a response.
