Hi All!
I ordered a new motor and gasket kit for my Pentair 2HP pump. When I spin the new motor shaft it is much quieter then my old motor that failed so that part is awesome! The new motor shaft doesn't spin as easily as the old one which I attribute to fully greased bearings and it being new. I was able to replace the mechanical seal with new parts and get the back plate back on. I then screwed on the impeller while holding the shaft at the back of the motor with my hand until the shaft started turning. I then held it with a wrench and snugged it down. I put the screw back in and thought the rest would be easy until I tried to spin the impeller and it wouldn't move. I put a wrench on the shaft and confirmed it turns but it is stiff.
My question is have I done something wrong or is it being stiff normal until the mechanical seal seats in properly. I hate to install it and then wear out the new motor but I also hate to not screw the impeller down and have it wobble while pumping. Any thoughts would be appreciated!
