Just inside the opening there is a lever that can be moved to different positions within the opening. On the back of an alarm clock, you will see a crescent-shaped opening. These factors are best evaluated with a movement inspection by Ken's Clock Clinic. It largely depends on the quality of the previous cleaning and repairing, how well the clock has been cared for, and its degree of use and wear. It's very difficult to say how long the interval between cleanings should be. Over-oiling also stains dials, ruins paint, and leaks out on you.Įven clocks that are meticulously oiled on a regular interval cannot escape an eventual cleaning. Over-oiling attracts more dirt and drags oil out of critical areas leaving friction areas dry of oil. A clock oiled every 2-3 years has an infinitely better chance of lasting than a clock that is never cared for, oiled with the wrong lubricant, or even over-oiled. How long this takes depends on the oil, the environment, and of course, the design of the clock. If you're lucky, the oil will dry to the point where it stops the clock before more serious damage is done. If left alone without oil, most clocks will wear themselves out. This gunk often acts as a grinding medium and causes the movement to wear out. All of these factors combined result in a pasty abrasive gunk where there was once oil. However, with time, dust and dirt from the outside get into these friction areas and cause the oil to dry out. These tiny particles are held in suspension by the oil and are generally not a cause of great concern. Over time, these metal parts rub or roll against each other and, even in the presence of fresh oil, rub off small metal particles. When new, the moving parts, friction areas, pivots and bearings within the clock are oiled to minimize metal-to-metal resistance (called friction) that is ever present in any machine. There are also some moving parts within a clock that are not oiled. Also remember that proper oiling of a movement often involves more than one type of clock oil or grease. There are some very good clock oils available on the market today and, when applied to a properly repaired and adjusted movement, will provide excellent protection from wear-and tend to stay where put. Although they don't do anywhere near the damage that WD-40 does, they will also tend to run out and stain dials. Sewing machine oils are generally highly viscous in nature, and won't stay put on the small pivots found in clock movements. Please avoid this material, even as a temporary fix. It gums up the fine movements, runs out onto dials and stains them, and contaminates clock-cleaning solutions when it inevitably becomes necessary to properly clean the movement. Clocks oiled with WD-40 may run for a short time, but will soon gum up again-and this time for the worst. While it is an awesome lubricant meant to be used for general household uses (like door latches, hinges, rusted bolts and power tools), it is NOT suitable for clock repair. One of the worst enemies of clock movements is WD-40. Can I oil an alarm clock with WD-40 or sewing machine oil to get it to run again?
We recommend that an alarm clock be inspected and reoiled every 2-3 years, especially if the clock is wound on a regular basis.
How often should I have my alarm clock collection oiled? In either case, the spring will need to be replaced or (in rare cases) repaired. However, if the spring has broken on the outside of its coil, it will sometimes partially wind, then "slip." If it is wound to just before this slip occurs, there may be enough power available from the spring to run the clock for a short time. If this happens, no power can be delivered to the movement. Most often the mainspring will break near the inside of its coil. When a clock winds but the spring does not become significantly tighter, the cause is usually a broken mainspring. The clock only seems to run for about a half day. It is difficult to determine the cause without inspecting the movement. The clock ends up fully wound because winding is the first thing we try when a clock has stopped. When the condition of a clock is described as "overwound," there is always another underlying cause for why the clock will not run. At this point, the spring is tight and capable of delivering the most power to the clock. Specifically, if a clock is wound fully, eventually the winding key will no longer turn. Often, one sees clocks advertised on Ebay and elsewhere as "not running, probably overwound." The fact is, there is no way to overwind a clock. What does it mean when a clock is overwound?
