Clock Repair Service Clock Repair Center Details Between our precision tools and our 80+ years of combined experience we can perform the best of service. When a clock comes in for repair, it always goes through the same basic procedure. Read More » A clock repair overhaul consists of the total dismantling of the movement, inspection of every pivot and every bushing hole to determine the best course of action with the repair process. Sometimes with broken mainsprings there is damage to the wheel train on the pinions and pivots, all this is looked over with magnification. Then we manually clean the clock parts with a cotton cloth and peg wood to be sure we get off all the old oil that has solidified and became an abrasive rather than a lubricant. This tedious process is then followed by pivot polishing and rebushing, where it is required. After all this, it’s time for the ultrasonic cleaning machine. Then rinsing is required, followed by the drying process and then oiling. The last step is to rebuild the clock movement followed by testing. If it fails in testing, all this is done again. Definition of Bushings = A bushing is a round hole in a round brass sleeve, that is very small. Bushings are needed when the pivots (located on the ends of the internal spinning arbor / gears), wear oblong holes in the outer plates instead of there usual round holes. We take the movement apart and use the bushing machine to ream out the oblong holes to accept the new round hole bushing via friction fit. During this process we examine the pivots with magnification and polish them with fine emery sticks if needed. The overall goal in this process is to have the least amount of friction in the movement, having a round post (pivot) spinning in a round hole (bushing) with the least friction is best. Definition of Polishing = We examine the pivots to be sure they are not bent or broken and see if it needs the polishing to smooth it out. A pivot is the skinny end of a arbor, the arbor is the post that the clocks gears are attached to. If the pivot polishing is needed, The arbor goes into the watchmakers lathe's collet, and we will use the fine emery sticks to polish the pivot back to a smooth finish as it rotates. This will give the pivot a high polish and this polish reduces friction in the outer plate's brass bushings. What Clock Parts To Send Please send the movement only along with a note saying how much each weight weighs (if weight driven) and your contact information. Read More » Please do not send keys, dial, hands, chime block, weights or pendulum as we have them here in the shop. We are not responsible for any clock case damage that is shipped to us. Please do not send the clock case. Clock Repairs Not to Send We do not work on alarm clocks, electric clocks, Anniversary clocks or Cuckoo clocks. Most of the time, alarm and electric clock parts are obsolete and simply not available to repair these movements. Read More » Anniversary clocks ALWAYS get the suspension spring kinked in shipping no matter how well it is packed, or by the person setting it back up. Cuckoo clocks are extremely prone to damage because the entire clock has to be shipped and the cases do not hold up well in the shipping process. Packing the Movement When packing up the movement, take special care to protect the hand shaft as this is hard to correct if it gets bent. This is the shaft that the hands go on to tell the time. Read More » You should pack the movement up well with newspaper and bubble wrap, or put the movement in a plastic bag and then use peanuts. If you use peanuts, please DO NOT let the movement get peanuts all up inside of it. Make sure you place the movement in the box with the hand shaft pointing up. Once you have the movement packed really well in a box, pack it again in another box with more packing material. Double boxing provides extra cushion for the movement as it travels to minimize the possibility of damage. Clock Movement Removal To remove your movement to send it in for Clock Repair, take off the hands by holding the minute hand and turning the minute hand nut to the left. Read More » Once this nut is off, the minute hand will come off. To get the hour hand off, twist it and pull it toward you and it will come off as it is only a friction fit. Remove any weights or pendulum that may be on the clock. Take the screws out that hold the movement in place. In grandfather clocks, these would be on the bottom of the movement going up to the outside arbors; for mantle and wall clocks they would be toward the front or back of the case. The dial on most grandfather clocks are either attached to the case or to the movement itself. If it is attached to the movement, unclip it off of the back side of the front plate of the movement. Hole End Mainspring replacement service If going with the mainspring replacement because the clock is still in good shape or out of production new, then if you choose to send the entire barrel with the mainspring in it, we can swap it out for $30. Read More » We will take out the mainspring and measure the width / thickness and approximate length and then install the correct spring back into the barrel. It will end up being the 30 charge, and then add the price of the mainspring as stated on the hole end mainspring chart , and then shipping back to you. If you would like to send in your barrel with the broken mainspring in it for us to replace, please fill out the form below and select the option for sending the barrel and mainspring only. What will be done? If your clock movement is not in production anymore and available new, the clock would need to be cleaned, repair any worn parts, oiled and tested. Read More » Oil solidifies over time and becomes an abrasive rather than a lubricant. The old oil must be removed and fresh oil put in its place. Often enough the clock has not been cleaned in a very long time. This means the oil has solidified and instead of lubricating the mechanical components as it should, it is doing the opposite and the oil is wearing things out. Sometimes you can see the solidified oil and sometimes you can’t as it may only be in the round pivot holes of the movement and the pinions that the gears mesh into. The parts that go through the outer brass plates and spin inside of the holes are called pivots; the holes are called pivot holes or bushings. What gets worn out, or what makes the clock not function after a while, is that the pivot holes become oblong instead of round. When the pivot holes are oblong, it creates friction on the pivot and also the gears mesh together further and this stops the clock from one or more of its functions (Time, Strike, or chime.) Replacing the old Movement Instead If the clock was made after 1965 then it is usually available brand new and we would have it in stock. This makes even more sense than getting your clock cleaned and oiled. Read More » The movement would be exactly like the movement you now have only brand new with factory improvements. What is meant by factory improvements is that as they see the clocks performance over many years, if anything can be improved upon then they will use this improvement on movements that they are making. This sometimes includes bronze bushings in key wear areas to make the clock last longer than it did in the past. If a clock movement is sent to us for a repair, we can clean it and oil it, repair it and put bushings in it all we want, but it’s not going to be as good as a brand new unit from the factory. In this case, having us clean your clock movement is only recommended after you have attempted to put the clock in beat per the instructions, and you have confirmed that your particular movement is no longer in production. This link will help you find a replacement movement by letting you determine the manufacturer of the clock movement, tell you if it’s still in production, and if it is, where you can purchase the movement brand new from our site. Repair Estimates and Where to Send There is a fee of $200 to take the movement in and inspect it. This fee includes a cleaning of the movement, the movement will usually look like new as we have the best cleaning solutions and machinery. Here we have before and after pictures of a movement cleaning, and in no way is this the most dramatic, it is a typical cleaning. The old oil is removed and the plates brightened, and the movement will last much longer. The enemy of a clock movement is the dried up old oil as the friction from the moving parts with the dry oil, creates wear in the outer plates pivot holes. The only way for us to see what is really going on with the movement is to clean it first. This is a non refundable fee and would be included with the movement shipped to us. This fee includes diagnosing issues and presenting the movements situation to the customer. Below is a basic guideline for what it could cost for a repair. If the clock needs special work, gear cutting, or replacement parts,then additional charges will apply. The $200 fee will be in addition to these approximate repair quotes. The three train units are the hardest to give an approximate quote as some are very tricky such as large tubular bell units.
