Chriseames 168, I have moved your post to the clock corner. Hope you don't mind.

 

I think I know the movement. One with a large balance wheel. What do you mean by side movement? Photo please of the clock would help.

Dear clock man,what I am saying is the air spring is not staying level when it moves back and forward it has got a lot of up and down movement too so it. Stops running as hits the side plate,looks like the pivot hole may be worn so maybe why it is getting the side unwanted movement, thank you again for your help,

This is not the type I thought of. It sound to me as if the balance staff might have broken, if there is too much play. Can you remove the two screws and remove the balance complete and look at the balance pivots, also the jewel holes, then could you post a photo, I can then advise you on what to do.

Dose balance wheel wobble?

[chriseames168]

Hi,Yes it does wobble,when I put the clock face up lay it down the clock runs perfectly,like it did before,the balance wheel spring does still sit in ok the plates and does have some movement on each side of pivot hole so I think the pivot maybe worm of salf pin could be,but to be honest,not sure on how to repair,old hippy has ask me to take the unit out and take photos and he may advise me,have you got any idea as clock was also running perfect and just stopped one day and now get this wobble problem and doesn't keep running,only runs ok now when face up or down.,thank you again Chris.

Wobble of the wheel points out to either a broken pivot or warped wheel, that it stops reinforces the broken pivot assumption.

Hairspring coil is to be concentric( concentric circles), if coils are pushed to the side, it would need to be sorted out to bring all circles back to concentric, level and flat.

Once you take the balance complete out, both above said faults will be obvious and easy to see what we are talking about and pics help.

Hi A balance behaving as you have said would points to a broken staff pivot or jewel as the pivots when correctly fitted keeps  the balance verticle  with minimum of side shake and end shake. It is possible that the balance spring is deformed,   The only way to be sure is to remove the platform escapement and check.    BEFORE removing the escapement remove ALL power from the mainspring or you risk damaging the movement.       The attached PDFwill give you guidance.      cheers
