Refurbishing Movement and Updating Case of Gilbert Admiral Clock
In the world of antique clock repair, fixing a cracked center pinion in a No. 3027 Gilbert Admiral clock is a meticulous task that demands precision and a certain level of horological skill. Here's a general guide on how you might approach this repair:
1. Assess the Damage
- Carefully remove the movement from the clock case.
- Inspect the center pinion thoroughly to confirm the crack and assess its extent.
2. Disassemble Carefully
- Using appropriate watchmaker’s screwdrivers and tweezers, disassemble the movement with utmost care to access the center pinion.
- Keep all parts organized to avoid confusion during reassembly.
3. Evaluate Repair Options
- If the crack is minor and repairable:
- A skilled horologist might be able to epoxy or weld the crack, but this is delicate and risks imbalance.
- The repaired pinion must maintain its exact alignment and balance.
- Preferred option:
- Source a replacement pinion. Given the specific model (Gilbert Admiral No. 3027), you might find parts with vintage clock suppliers or horologist forums.
- Alternatively, have a skilled clockmaker fabricate a new pinion matching the original specifications.
4. Cleaning and Inspection
- Clean the pinion seat and arbor to remove any wear or debris.
- Check all other gears and pivots for wear/damage.
5. Installation
- Reinstall the repaired or replacement center pinion with precise alignment.
- Ensure the pinion meshes correctly with adjoining gears.
- Lubricate pivots sparingly with clock oil.
6. Testing and Adjustment
- Before fully reassembling the clock case, test the movement for smooth operation.
- Make any timing adjustments as necessary.
- Once satisfied, reinstall the movement in the clock case.
Additional Tips
- Repair or replacement of center pinions is often best left to professional clockmakers because of the precision involved.

- Document each step and take photos to assist in reassembly.
