    Not much to go on here, "very little access to it" perhaps if you could post a photo of what your dealing with, someone could provide a useful solution.

    Clean shaft, heat frozen bearing race and remove. If you didn't need to save the bearing, I would cut the outer and inner races and peel it off the shaft.

    A picture would be a real help. What type of bearing are you dealing wtih?
    Some bearings will bind on the shaft when you pull on the outer race.
    Dry ice can sometimes be a help. Liquid propane used to work, but not so much any more. It doesn't seem the same.

    Yea.....a pic would work wonders. How big is the bearing/shaft? $2500 a pop sounds pretty big to me.....If I could I would remove the shaft and use a shop press.....

    Is it possible you could use a slice wheel and cut short of all the way through the bearing's race.

    Also could try putting some pentrating oil on the bearing and with a piece of brass against the end of the shaft hit it with an air hammer. I'm thinking the shaft is out of what ever it was in and on the work bench.

    Smile are there too many zeros?

    As others said a picture would help and a 2500.00 bearing is something to show.

    Default So, What happened?

    Did the bearings get pulled, cut, project bailed on, or what?

    I use a plasma cutter, pretty easy, just have to have a fire extinguisher handy, one the bearing shell is off, the bearings or rollers come off, then all I do is heat the bearing collar with the plasma, and out it comes

    bearing puller with heat will help, keep heating and cooling to get it unfrozen. a hammer to the race, with heat and the bearing puller should shock it loose.
