CLA on Jupiters

I use a graphite grease for the diapraghm ring as it gives a more positive feel. For the main helix, I use a red fully synthetic grease. I find the white lithium grease just a bit too viscous and the lighter grease gives more control especially on the J9. The important thing is that the grease doesn't "creep".

Re: Kim's right about Jupiter-9. This lens has more helixes, and it is better to use something "thinner" than the white grease. Therefore when I work with this lens I use some very light fully synthetic grease and the focussing is butter smooth.
 
I only had to clean and lube the helixes of my otherwise perfect J9. I used ball-bearing grease and managed to put the puzzle back together again. Focus remains a little stiff at one spot though, but that may be a tiny local damage somewhere inside.
After that I sold my fat Tele-Elmarit. That's how much I love the J9.
 
I've used petrol-free, silicon-based industrial greases for my lenses. White lithium grease and graphite are also good choice, although graphite can get more viscous at very low temp.
 
The helicals of many fsu lenses require heavier grease. Light greases may make the helicals move more smoothly, but can also cause them to slip and lose accuracy. This is an issue with lenses which use multiple helicoids. Many LTM RF J-9 for example, make focusing errors with thinner grease. Automotive axle grease mimics appears to have the qualities of the original grease used.
 
Hi, I use for the main helix aeroshell grease 7 and it's great.😉😉

The best choice is the Isoflex Topas L32 used by Ferrari Concorde and Hasselblad/Zeiss lenses, but it's too expensive.😀😀

I was looking for this one specifically: can it be ordered online anywhere, in consumer amounts?
