Hello,

I have this clock movement with the name John Fisher, Preston on the dial that I bought from the UK.
The wheel that drives the hour pipe/snail has a badly worn pinion.
The wheel tooth count has 36 teeth, the pinion has 6 leaves.
It also has the pin that kicks of the hour striking.
I do not have the ability or tools to make a new one.
I am looking for a source to make a new one.
Photos are attached.
Thanks for your help.

From the pictures, the pinion doesn't look that bad. Does it cause any problems?

I agree. That pinion/gear does not need to be snug like other ones. There is little pressure on it. Let us know what problems you are having.

Very intermittently, the hour and minute hands stop moving but the movement continues to run. The motion work binds up. The minute hand cannot be moved manually. Touching the wheel slightly cause a tink sound and the motion work unbinds. Looking at the pinion from the side, the leaves are worn in a conical fashion. The leaves are shorter on the top of the pinion than at its base. When it binds you can see the mesh is not right. The teeth on the other motion work wheels show virtually no wear at all. I believe this movement was assembled from extra parts someone had laying around.

Check your chime warning pin. If it's not adjusted right, it can catch on the chime lever as it is rising and hose up the clock. Your symptoms sound like that's what's happening. You have to catch it in the act, so to speak, because it's a random issue usually.

Thanks, but the clock never stops when the warning or the strike happens.

Should a washer be under the taper pin? Maybe that taper pin holding the wheel onto the post needs trimmed a bit?
