My waterfall pump was making noise and it was suppose to be a cold weekend here in Texas so I decided I'd replace the bearings in the motor. I have never done this before, but have the tools and watched several videos. I was able to remove the first 3 through bolts without any problems, but the last one finally broke when I applied some pressure to loosen it. I was able to get the motor apart and moved the piece to the garage where I sprayed it with some WD40. I tried removing the bolt with some vice grips and the bolt continued to break. I got down to about 3 inches of bolt left and soaked it with WD40 overnight. Today, I tried again and continued to break the bolt until I had only about 2 inches of bolt left. At that point I fired up the propane torch and heated the base for a few minutes. I was then able to see the bolt turn a little in both directions and did this several times. I could hear squeaking so I thought I had it. As I repositioned the vise grips and turned one last time, the bolt broke off just below the surface! I guess now I need to drill it out?
Unsuccessful with the bolt, I decided to replace the bearings. However, I am unable to get the bearing out of the pump housing (I guess that is what it is). I have sprayed both sides of the bearing housing with WD40 and have beat the housing with a hammer to break it free of the bearing, but it will not move!
Any idea how to get the housing off so I can replace the bearing?? Picture attached.
