"Factory-tight" bolt in my washer: Won't budge! [View all]

I'm trying to get the rotor and stator out of the back of my LG washer to change out the Hall sensor, but the bolt holding the rotor on is majorly stuck. Not gunky or rusty, clean as a whistle -- just won't budge. This is my first time in there doing any work, so this bolt has never been loosened. I'm using a regular ratchet socket wrench, to no avail. I even tried banging the wrench handle with a hammer, and applying my weight to the wrench handle by pushing on it with my foot from a standing position. This thing is ridiculously tight.

Any suggestions? I'm thinking about getting a t-bar sliding breaker bar type of socket wrench, so I can get more leverage with the longer handle and also be able to apply force from both sides at once -- but don't want to spend the money if there's some obvious hack I'm missing. Plus, given my efforts so far, I'm not confident this would work either. Why would a factory-tight bolt be this tight??

I did try whacking it with a pipe wrench, since my hammer wasn't readily available. Beartracks Saturday #21

Whaaat? Although, this tracks with my experience. The bolt acts like it's fused to the rotor metal. Beartracks Saturday #18
Some people have suggested PB Blaster. Would that work on glue, or is it only for rust/gunk? Beartracks Saturday #22
If you have a length of pvc pipe that you can slip on the ratchet handle that will add leverage. Good luck! Floyd R. Turbo Saturday #6
I like the idea of sliding the rachet handle into a long pipe. dem4decades Saturday #7

Motor is fine. It's an LG. I'm just needing to replace the sensor. Beartracks Saturday #14
Could it be a left-hand thread? Some bolts are opposite to avoid loosening. Norrrm Saturday #23
