Most clock repairs involve bushing worn pivot holes. Worn pivot holes cause the clock to stop. The geared wheels move away from their centers, resulting in binding of the teeth.
Clock bushing involves:
- Finding the true center of the worn pivot hole.
- Determining the correct replacement KWM bushing and the proper reamer to use.
- Centering and reaming out the old bushing
- Pressing in the new KWM bushing. Using the proper size replacement bushing will ensure the pivot fits correctly and the wheel will have the correct endshake.
