How to Oil a Clock Movement
OK you are sitting there and you are trying to remember the last time your clock was oiled. The general rule is that it needs to be oiled every 3 years. To oil your clock just follow these steps:
1. Open the bezel and remove the hands. Most of the time they are held on with a nut but some (old Seth Thomas comes to mind) have a pin that needs to be removed first. Make sure to put them in a sandwich bag now. If you drop it or loose it you will have a hard time trying to find another that matches the thread on your dial (been there done that and it sucks).
2. Now remove the 4 screws inside the case that mounts your movement to the case. At this point you should be holding the movement in your hand.
3. Next grab your oiler and starting with the strike mainspring (S #1) apply a couple drops of oil, go to the next pivot hole in the strike train and do the same. Continue to do this all the way up the strike train. When you have completed the strike train, repeat the process on the time train. Now just flip the movement over and repeat the process on this side.
4. Now we will oil the mainsprings, some people recommend using 30 weight car oil and other people will tell you something different. I will let you sort that one out.
5. I like to oil the cannon pinions and the verge also. The thought process is the easier the gears turn the smoother the clock will run.
6. Reassemble, your clock should be happy now.
