I got up this morning and felt a disturbance in the force, went out in the shop and noticed there was no lister noise, mine runs/ran 24/7, so I opened the door on it's room and noticed right away the belt was off, then I noticed the IP side flywheel was at about a 25 degree angle to the center line and the main bearing casting was shattered.
Then I looked at the other side and noticed the same thing.
I shut the door and came back in for some breakfast, I'll get some pics later today and possibly start the tear down, it does not look like the block is broken.
