Clock mainspring repair

Many modern grandfather, wall and mantel clocks contain movements manufactured by Franz Hermle in Germany. The mainsprings of some of these clock movements are contained within barrels that can easily be removed without dismantling the entire movement! Simply remove the arbor from the spring barrel, remove the offending barrel, note the number stamped on the barrel cover, and order a replacement from any of the clock repair supply companies. Installation is the exact opposite of removal.

Caution: Never remove a clock barrel whose spring is fully or partially wound up. Doing so could cause injury to the clock or to yourself! Make sure that the spring is indeed broken by winding the arbor. If it winds without any back pressure, it's broken!
