Hi all
Complete new member here and have a pondering issue with a German clock I think.
I have found the damage arbour and trundles but for the life of me I cannot seem to figure out how to remove this.
Any help or advice greatly accepted

Regards Dave

Welcome Dave!
Had that problem more times than I should admit.
Easy remedy though. I would start by removing the
arbor from the plate. You will need to remove
the countwheel from the arbor. Then you can use a
crows foot or any split stake to tap either the wheel
or the collar back or completely off of the arbor.
I prefer removing the collar
unless the wheel needs to be repositioned for some reason.
Here’s a pic of a crows foot set up for the same operation.

Hi Phil
Thank you very much for the reply, the issue I have is when the trundles snapped I think the force pushed the wheel and it is jammed as hopefully you can see!
My thoughts I soaked it with WD40 then using gloves I can turn the wheel but this is tight! So do I use a punch and drive the wheel out to free the damaged one so I can repair the trundles and arbour? Do I heat the wheel then drive the damaged wheel out!
Hopefully the pics can explain and show you

Hi Dave
Sorry for not answering sooner. I was away for the day but will be home for the next several days.
I see what you mean now. You know I’m just guessing here but from your photos it sure seems like the mainspring still has tension on it and has jammed the barrel teeth against the collet on the wheel arbor. If so then you will need to carefully release that tension before going any further. You should then be able to remove the count wheel with a punch after the mainspring power is let down.
What do you think?
Phil

Hi Phil
Thank you tension all released from main spring and my thoughts I have to punch the wheel from the counter wheel. Tried by hand but it is solid, when the arbours went it went with some force!!

That’s great Dave!
Yes the arbor should tap out without too much trouble. If you do decide to apply some heat you can put a steel or brass tube over the collar and then heat the tube with a flame allowing the heat to transfer to the collar. Much easier to target and control the amount of heat this way.
Count wheels are often mounted onto square ended arbors to prevent slipping. Yours appears to be mounted onto a round end so possibly it’s a tighter press fit to keep it from slipping. Not sure. Can’t tell from the pic but hopefully not much damage occurred to the barrel teeth.
Please let us know how it goes Dave.
Best, Phil

Well done! You got it, that’s good news Dave!
A click spring is what you’re looking for. Most clock supply houses should have one for your clock. The following TimeSavers page in the U.s. shows a bunch to choose from. European suppliers like Cousins in the UK might have a better selection for European clocks though. Not sure. Here’s the link to TimeSavers. https://timesavers.com/search.html?q=Click+spring+&go=Search
Congratulations on removing that count wheel Dave!
Best, Phil

Thank you for the support and help much appreciated. I will order a selection from cousins here in the UK. I am really pleased with myself on two counts, one to remove the count wheel and re-straighten it that was really tight!
I have on previous clock replaced the mainsprings, there seems to be a lot of information and two camps one saying leave alone and just oil. The second while the clock is dismantled take the opportunity and replace them.
Another is to clean and polish the brass and pivots another not too!

Thanks a lot Phil

Dave
