The lubrication of tape recorders is a seemingly simple subject, but if you want to extend the life of the devices and space out maintenance, you have to choose the right oil or grease. Tis tutorial ia a translation of a French version under review. In a first step I will use google to translate
The oils
The easiest way is to choose the oil recommended by the manufacturer (in yellow), which is very expensive and may only be suitable for certain models/brands. In addition, different oils are needed depending on the part to be lubricated.
Browsing through a few forums and doing some research, I've compiled the info in the following table.
Personally (in green) for the capstans, I use a motor oil of medium viscosity but very stable in temperature, much less expensive, I use a motor oil of very high viscosity index. For the various wheels and wheels as well as for the levers, a fairly fluid hydraulic oil. It's up to you to see if it suits your device and the materials (ferrous metals, Cu and alloys, plastics) that make it up.
It is essential to clean off all traces of the old lubricant which may not be of the same nature and which may not be compatible with the new one; we can for example put in excess to "drive out" the old lubricant and then remove the excess.
