To repair an old Kieninger clock movement would cost the same, if not more, than a new movement. The new Kieninger clock movement can ship the same day as the order, costs less money, and is easier to deal with than having the old movement cleaned and overhauled.
A new mechanical clock movement can ship from USA the same day you order it, so the time it takes you to get you're clock up and running is very short. A repair can usually take months and then you are still left with a used overhauled movement rather than a new one.
When you receive a new movement it is the same as you're old movement, so all clock components will fit on to the new movement. The cost of a new movement is usually the same if not less than a cleaning on the old unit, and when it's installed it should last another 25-30 years without thinking about replacing or servicing it again. Some new units have bronzed bushings in key wear areas to increase the life of the movement, and on the non-pendulum units the balance has been improved upon for longer life and ease of timing. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.
The numbers on the brass back plate of the Kieninger clock movement is where we need to start with the identification, so we can determine the proper replacement.
The numbers and or letters may tell us the year it was produced, what letter movement series it is (this will also tell us the plate size) and then the CM length of the pendulum from the top of the movement down to the bottom of the pendulum rating nut threads. (based on a 4 1/2 inch bob diameter)
With the numbers off of the back plate of the Kieninger mechanical clock movement, we can now figure out the correct replacement movement.
The new movement will fit into the clock case just as the old one did, using the same components such as the dial and pendulum. So lets say the movement's numbers are 81 K 116cm, the 81 is the year produced (1981) and the K is the movements series and plate size, and the 116 is the pendulum length, in centimeters, from the top of the movement all the down to the bottom of the rating nut, based on a smallest 4 1/2 inch bob diameter. Now in that previous sentence we said that 81 was the date, however this has changed in the later years. After a certain date that first number is no longer the date produced. So it may or may not be the date, but you can just ignore that first number anyway as it does not matter when replacing the movement anyway.
If this decoding process is a bother or is confusing, just email the information off of the back plate of the clock movement to us with a picture to [email protected], or call us at 800-381-7458 and we can help.
Kieninger is the oldest existing manufacturer of mechanical movements for floor, wall and mantel clocks in the world.
The Kieninger movement excels with a high level of design and manufacturing quality. Numerous innovations and patents (16-rod chimes; second indication for pendulum lengths under 116 cm; automatic beat adjustment, night time shut-off systems for 1/2-hour and 1/4-hour movements; automatic chime sequencing; various manufacturing processes and components) are the measure for design quality.
Manufacturing quality shows in every Kieninger Clock Movement: All Kieninger Clock Movement plates are made of a special brass alloy which is hard and has a tensile strength of 53 kp/mm2. The holes for the journals are reamed and smoothed after lacquering and then receive an oil sink.
Each Kieninger Clock Movement has pinions which are made of high-quality steel or stainless steel. Fast turning pinions are hardened. All journals are roller burnished in a special process. Some movements feature bronze-bushings and/or jewels in critical positions. The gears in the Kieninger Clock Movement are made of a very tough and hard brass alloy with a tensile strength of 62 kp/mm2.
A high level of corrosion protection for all components is assured. Brass components are pickled and receive a coat of clear lacquer. Steel components are made from stainless steel or receive a galvanic nickel coating. Each Kieninger Clock Movement has a laser engraved serial number.
Three Weight Rectangle Units
The K units are the most produced 3 weight movement series that Kieninger has created. They have a hand shaft length of 47mm from the front plate of the movement and out to the end of the minute hand nut threads. The movement will have a date code, then K and then the CM length listed on the back plate of the movement.
The MS / MSU have a hand shaft length of 47mm from the front plate out. The movement may have a date code, then MS or MSU and then the CM length listed on the back plate of the movement. Such as MSU 116CM. The MSU is interchangeable with the KSU, its the same unit but slightly lower grade.
The largest of the Kieninger movements, this is the 9 tubular bell clock movement. This is the only 9 tube movement that Kieninger made, so if your movement has 9 tubes hanging on the back, and says Kieninger, is cable driven, this is the right unit. Despite its menacing appearance, this unit is very easy to install and set up.
Large 6 x 9 chain driven clock movement that would say Kieninger on the movement and 116cm. Available in Westminster only (8 hammers 4+4) or triple chime (12 hammers 4+8). They both have a hand shaft length of 56mm from the front plate of the movement and all the way out to the end of the minute hand nut threads.
Three Weight Square Units
Square Westminster chain driven movement will say on the back plate something similar to 79 RK 93CM. The movements hand shaft is measured from the front plate all the way out to the very end of the minute hands rating nut threads.
Square, triple chime, chain driven movement will say on the back plate something similar to 79 R 93CM or 81 RU 116cm. The movements hand shaft is measured from the front plate all the way out to the very end of the minute hands rating nut threads.
Square, Westminster chime, chain driven movement will say on the back plate something similar to 79 SKS 116CM or 80 SK 116cm. The hammer location on these are either 8 (4-4) on the back of the unit, or 5 hammers on the side. The hand shaft length on this series is 36mm long.
Two Weight and One Weight
PS and PSO is a compact cable driven unit with two weights, one for the time and one for the gong strike. This PS or PSO Kieninger clock movement will have only one hammer on it for the gong strike. The movement comes with the leader, suspension spring, hand nut, cables and pulleys. The movement your replacing may have a date code, and then will have PS or PSO stamped on the back plate and then a CM number. Such as 80 PS 65CM
PS and PSO is a compact cable driven unit with two weights, one for the time and one for the BimBam strike. This PS or PSO Kieninger clock movement will have 3 hammers on it for the BimBam strike. The movement comes with the leader, suspension spring, hand nut, cables and pulleys. The movement your replacing may have a date code, and then will have PS or PSO stamped on the back plate and then a CM number. Such as 80 PS 65CM
These Westminster chime, one weight and two spring RWS wall clock units usually have 8 (4+4) hammers on the back unless its side strike, if side it will have 5 hammers on the side. The CM number will be stamped on the unit such as 81 R 65cm or 80 RWS 80cm. That first number is the date of manufacture, the R is the series, and the CM is the pendulum length from the top of the movement and down. This is a very popular movement for a regulator style wall clock.
Spring Driven Units
Westminster chime with 5 hammers below the movement, spring driven, has a balance escapement rather than the pendulum. The movement may have AEL01 or AEL02 or AEL12 on the back of it, but there all the same AEL movement. The movement has a 32mm hand shaft length from the front plate of the movement to the end of the minute hand nut threads.
The APL is similar to the AEL units but is a pendulum unit instead of balance wheel. The movement also has two different hand shaft options, this again is measured from the front plate all the way out in mm. Since this is a pendulum unit there will be a CM mark on the back of the old unit to match up with the options below.
This is the triple chime spring driven series with a balance escapement. The movement comes in two different hand shaft lengths, this is measured in mm from the front plate of the movement all the way out to the end of the minute hand nut threads.
The SPS Kieninger clock movement is a Westminster chime, spring driven, pendulum unit. It has a 36mm hand shaft length from the front plate of the movement to the end of the minute hand nut threads.
