So I acquired a used Magnetek 2HP B985 dual speed motor to replace a failed B855 on my 2HP Challenger pump. Some pics attached.
The motor came attached to a pump and filter as shown in the pics. I'm having trouble removing the center screw on the impeller, which seems to be locked up by corrosion. I'm assuming it is reverse threaded and have been hitting it with WD-40 to loosen it up. Let me know if I should do anything different.
Also, when I popped the rear cap to access the shaft, I noticed that the rear end of the shaft is pretty corroded (pic attached), and while the shaft turns freely by hand, it just feels like there's a little grit somewhere - maybe I'm imagining it.
I'm planning to replace the shaft seal for sure, but was wondering if I should replace the bearings too while I'm at it. How big of a pain is it to take the motor apart and replace the bearings? Or is it OK to run the motor as is for some time and replace the bearings at a later time?
Thanks for your input!
