    I have this very old L&R three jar watch cleaner that works very nice but it seems like it needs oil. There is a cap on top that says oil but I cannot find anywhere on the net what kind to use or how much? Also on the sides there are caps that unscrew, anyone know what those are for ?

    Any lightweight oil will work just fine. It doesn't have to be anything exotic. My favorite for that kind of thing is sewing machine oil. (I prefer synthetic, but it doesn't have to be.) 3-in-1 or gun oil or whatever will be good if you already have it.

    As for how much, a couple of drops will probably do it.

    The caps on the sides are for the brushes. There are springs behind them that hold carbon brushes against the commutator of the motor to complete the electric circuit so the motor will work. When the brushes wear out it's usually pretty easy to find replacements. They don't have to be exactly the same brand, just the same shape so they'll fit. If you unscrew one of the caps and pull one of the brushes out you'll see what they look like. Just pay attention to how they come out and put them back in the same way.

    Hope this helps.

    Hi Glen, thanks for for your help. So do I fill that oil reservoir or just add a little once in a while:???:

    Another good question. On my motors like that I add a drop or two every once in a while, especially with a motor that doesn't see a lot of use.
