    Hi guys.
    Any of you chaps got any ideas on the removal of this headstock spindle bearing . I cnt clean it in situ but if possible I would prefer to remove it for proper cleaning. I can't see away of doing it without distorting the disc that sits above it. 20181002_155314.jpg

    Surely that should just slide down the spindle?

    are you replacing it or just cleaning it?

    by the time you've gone to the trouble of removing it you might as well replace it... in which case just cut/split it off?

    if it's flat up against the disk above I can't see a decent way to get it off (if it's stuck)

    if you can a couple of bits of bar between the disk and bearing, you could turn it upside down, brace those flat bars against something and then hit the end of the center bar to knock it down through the bearing

    Definitely don't want to be replacing it. Not a the price of them.

    Tube end machined the size of the disc, stand bottom of the spindle in a bucket of ice, as the temprature drops and stick it in a press and push the besring down evenly on the sleeve.

    Since it's on the [lathe?]spindle, I'd personally favour thoroughly clean in situ.

    I think that's my only option as I think I will do more damage trying to remove it.

    Have you a drawing, as it will tell you the fit of the bearing to the shaft. If you give it a good clean, set it up in a press with a machined tube, and warm the besring with a catering blow lamp, you might be surprised how easily it comes off.

    I don't have any drawings or literature on the empire. But I will give it a go tomorrow.

    A wild stab, but try finding the patent numbers of the lathe, sometimes drawings can hide in there as I just found out with a project of my own

    I wouldn't try to remove it. I'd clean and flush the dried out grease first, then test-fit the opposing bearing. If that is tighter than a light press fit on the shaft I'd ease the fit with some emery then it's ready for re-assembly.
