    Default Another YT clever idea. Getting stuck bearing races out.

    This was in the context of bearing races where you cant actually get behind them to knock them out. Which is not usual where cars are concerned, but I thought it clever enough to share here anyway.

    Technique is to weld a bead around the exposed rim of the race. As the weld cools, it contracts and pulls the race in slightly, allowing it to be removed much more easily.

    Yes. I last did that to remove a failed main bearing on a DS hydraulic pump.

    That is how I remove CX rear arm bearings! Only I drop in the appropriate sized washer, so if heating it doesn't do the trick. The washer you have welded to the seat allows you to hammer it out with a punch.

    A similar technique is used to remove wet liners from blocks when they're stuck beyond help. A diesel engine engineer told me about it many moons ago. If worse comes to worst they used to weld a bar across the liner (inside) and pull at that.

    I've used this method for many years. Brewery fitter mate told me after I was trying to get 504 front hub shells out, one of the very old Crusty fitters told.
    One shell I couldn't budge at all, tried this and it fell out when I turned it over. Had almost resorted to getting new hubs.
