Hello,
I just bought an almost vintage '910' model (looks like a tank, eh?), which obviously was produced in the early 80s.
In order to bring it back to life, I plan to disassemble it completely. What type of lubricant can I use - especially for cleaning of the bearing and the parts near the shaft from old grease residues?
Can I clean it completely with
- alcohol/ cleaning solvent or
- WD-40 first?
Or shall I leave the (grewish) fatty residue and do nothing (the dismounted bearing appears to be slightly turnable with a finger, but when pushing down the completed foot pedal, the motion of the beater stops at once after coming back from the front).
I read that WD-40 is not suitable for greasing afterwards. As I have a precision grease (with emergency running properties, commonly used in RC model making), is that suitable for the bearing, too?
Or is simple sewing machine oil just the best way?
Any advice would be appreciated greatly. Please kindly consider that I am from Germany and a general advice would be more helpful than lubricants which might not be available in my country.
Thanks - Ralf
