zeiss jena coarse focus mechanism

Post by PeterArmitage »

Do any of you have experience dismantling, cleaning and greasing the coarse focus mechanism in a Carl Zeiss Jena Ergaval or Amplival microscope? I can't figure out how to completely dismantle the mechanism, and would appreciate advice re. how to proceed further than what you see in the appended photos. I took the base off and greased the gears as best I could, but I fear that I over greased them. As a result, I'm getting some slippage on the focus. I used a heavy grease for the lubrication, namely, Nyogel 795A. Thank you.
