    Just started dismantling clock and opened up spindle bearings. One glass has broken edges and no paper gaskets. I guess greaseproof paper would do.
    Ball bearings are OK but I need to move the ball race 180 degrees. But can't work out how to get them out. Light tapping on the back doesn't seem to move them.
    Hoping for any ideas?
    Thanks.

    Brass has greater thermal expansion than steel so maybe some gentle heat would allow you to slip out the race.

    There are many Eureka restorations posted on the web and this may be addressed in one of the pictorials.

    The glass is available from Carlton Clocks.

    I did look at a couple of Peter J Smith's Eureka restorations on the web and he does show the ball races removed. I thought he had described how he removed them in one of the reports.

    They are on the web as "restored_eureka_7502"

    I believe he had a business in the UK called Horoligix and was doing Eureka restorations at one time. There are many detailed restorations in pictures of many Eureka clocks, and I find them highly instructional.

    Hi i hope by the time you read this you would have been able to remove the outer shell of the ball race,one of my clocks had worn outer shell but was able to reposition it without problem,but i suspect it would have no difference even if i couldn't have,it ran before so there was no reason why it shouldn't carried on running as with yours,i would advise caution in trying to removing them,the casing might be brittle and even slight tapping of the case might result in crack/failure and the chance of getting another is none existent,hot water might expand the case enough, to allow movement,i have heard boiling oil as it holds more heat,Carlton Clocks UK has taken over from Peter Smith,and sell some parts,
