To prevent guessing the threads and distances, you should use a caliper and write down the exact height of the combined helicoids. You should also use clues or markings to remember which thread the helicoids broke apart. Good video btw.

[@claudiobozzini1502]

Thanks. following this video I recovered a Jupiter 9 from '77..and now it's perfect!

[@krisdraw]

Great tutorial! Just got done following this and it has really smoothed out the focus on my Jupiter 9.

Your video saved me from buying another lens....great stuff!

You're welcome!

[@PaulMuelller]

Thanks a lot! The dismounting wasn't that heavy... But then I hat six parts and no Idea! Thanks to you, with your help I was able to mount the Lens in correct way! Now it is working again!

[@natunoyuzu]

Aaaaaahhhhh it's really helpful!!! Thanks a looooot when I had taken it apart but found that I didn't know how to assemble it back to one.

[@Stihl_OK]

В который раз говорю вам спасибо! Много полезных нюансов подчерпнул на встретил на вашем канале.

[@davidus18]

Thank you so much. You helped me to reassemble my lens.

[@handadam]

That was a great video! I have never seen anything going into that level of detail for repairing lenses before. I was able to repair my Jupiter 9 by following you along. I did have a different model and it was very similar until got to a spring. Luckily I noticed before it expanded, because that would have made a mess of things. I was able to get everything back together and the lens is better than ever. Thanks so much for the video, it gave me the courage to fix a lens I now love to use. I will be watching more of your videos and be braver with repairs knowing you have provided such great instructions.

[@RetroFotoHouse]

Thank you for your kind words, this is good recompensation for my work

[@handadam]

I just checked you eBay store to see what you had and realized I bought my Contax to e-mount adapter from you about a year ago. Great adapter! It works perfectly for Jupiter lenses and Zeiss/Contax. I'll definitely buy my next Jupiter lens from you knowing how good the adapter is. Thanks again for the video and the adapter!

[@RetroFotoHouse]

You're welcome! :D

[@philmtx3fr]

As usual very good tutorial of great value. Thx a lot for that. I will just do 2 rems : 1/ When you pass a long time around 30' to find the right thread. Don't you think it would be better to mark when the ring dissassembles during dismounting ? Then about the grease : Personnaly I use japonese one which is white with very good durability and which needs very few indeed. I pass it with a brush and this prevents overlaod. If you are interested, I can pass a link to it. Anyway keep on doing these outstanding videos. You give a second (or third ) life to our favorite lenses and thx again for this !!!

[@RetroFotoHouse]

Well, i've found my proper way how to disassemble lens and i stick to it. Concerning a grease-i would be very grategul to you if you could send me a link Thank you for your input

[@vladbelch3981]

Hi, great video, but my problem is I bought the lens which someone tried to clean and didn't put any marking when the separated the helicoids. Any chance you can make a video to show how to reassemble helicoids and adjust focus to infinity without marking?

[@jdoggybizzle]

I hear a kitty!!! 3:54 This is probably what's wrong with my J9. The ring is stiff and the calibration is off on all of my Soviet cameras so I will give it a shot.

[@ИгорьУ-з1г]

Отличное видео👍. Но смазка ЦИАТИМ (по мнению пользователей) со временем опять стопорит регулировку резкости🤷‍♂️

You saved my lens. Thanks👌⚡

Just got one of these win grinding and stiff focus ring. Going ti use this tutorial to disassemble and regrease. Believe is a 1959 red P. The other issue is i think i originally bought wrong adapter for my sony fx3. Got a 39-42 step up ring with m42 to nex mount. No focus ability. So now waiting on l39 to nex. Its a rangefinder m39 mount. Update. New L39 to NEX adapter allows focus but minimum distance is more like 3M instead if the stated 1.5M on ring. I dont think double helicoid was set properly on service. Also grub screws were oartially broken and not flush so ground on focus ring. Be nice to know proper distances for parts with caliper than markings si ce i think it was improperly serviced.

[@SuperZenon72]

Hellow I boght this lens as new one. It is true. Focus ring in some point work wery hard. I wil try exchange grease. This is Jupiter-9 red 'P' rangefinder lens. realy any scrach on body and glas is perfect.

[@RetroFotoHouse]

yeah, it is very old. And requires a new grease for sure

[@VeitSchiffmann]

very good explained, thank you very much, very helpful!

Dude, this is for a very specific public... very few. But its really grate for those ones! Thanks a lot! I live in Brazil, we don't have this kind of skilled labour here. The technician that should lubrificate my Jupter-9 made a mess! It focus on infinity or at close distance. Im thinking of try to do by my self... I will wait his last try ( of 7 ) to fix it, and do it by myself. May i have your help? Or you can work on my lens?

[@dimadeni1695]

THANK YOU

[@zwannieboy]

I just bought a Jupiter 9 RF mount, this is slightly different then the M42 mount. i really would like to clean the helicoid, because its stiff, but cant find a good tutorial. I hope you can point me in the right direction. Nice video btw

[@RetroFotoHouse]

this vide is exactly about jupiter-9 RF

[@zwannieboy]

@@RetroFotoHouse sorry I meant the contax RF mount, also known as Nikon S

[@zwannieboy]

@@RetroFotoHouse Do you know any company or person near you who can relube my Jupiter 9, or even point m ein the right direction? I'm stuck in the last part of taking apart the helicoid, because the M42 mount is different from the Contax Mount.

[@nilzthorbo5437]

i have the common focus issue when using my jupiter 9 on my Leica m6. Can you tell how to fix this or generally hot wo adjust focus of Jupiters? Thank you for your tutorials. My Jupiter 9 and Jupiter 12 are very clean and smooth thanks to you. but i cant focus them correctly even on my zorki 4k. (zorki rangefinder is correct)

[@RetroFotoHouse]

i'm aware about this issue. That's a headache. You can try to adjust it by changing a thickness of aluminium adjusting ring situating between optical block and focusing block

[@tvnshack]

Thank you for the tutorial .... Any chance you do the same for a Contax/Kiev body as this part is totally different.

[@RetroFotoHouse]

yes, it is totally different. One day it will come for sure.

[@viktorbrunoe]

Hi! Great video. I have one early version of Jupiter 9. Serial starts with 69. I can't separate the helicoid completely. Can you make a video on how to?

[@RetroFotoHouse]

i would like to, but actually i do not have such lens

[@gakiyama01]

Hi, the last piece that you screw in for the reassembly (about 32:20), is this also a screw with 4 threads like the first and second one, or just one thread so if it fits, it is the right one? Thank you for your advice and great video!

[@henrikmadsen9483]

Very good! You rock

[@smoothsounds801]

I followed instructions step by step. Everything line up perfect. Focusing still really tight. Could the 2 retaining pins cause the tight focusing? Or can misalignment cause it?

[@RetroFotoHouse]

hard to say.. If you follow instructions step by step it should be allright than

[@arrodas]

Hi thank you very much for this excellent video!! it helps a lot, can you tell which grease is the one to use? brand ? which one to buy on ebay? there are so many with different viscosity numbers on it...

[@wolfman2247]

[@Ali.lensman]

What about jupiter 9 85mm f2 silver m39 slr version? I have one and focus ring is stiff... How can I lubricate it? 😉

[@rickardandersson8528]

i bought a used jupiter 8, it doesn't focus. all the parts move but the focus moves a maximum of 1cm from the near limit. Can this be saved? maybe someone opened it before and did not make the markings?

[@CraigMansfield]

Thank you very much.

Даа,а я вот не пометил перед разборкой думал да че там 3 винтика .В итоге сутки эту головоломку перебирал .То отверстия не совпадают то разметка то фокуса нет . Раз 100 разобрал собрал .

Hi mate! Nice video! I fixed one of those lenses few days ago (the fox using ring was completely stuck!). I wiped out the old grease and replaced it with one that I found in my garage... It works but it's note very smooth. Any advice of which grease to use? Grade of viscosity etc. Thanks again!

[@RetroFotoHouse]

+Stefano Padoan Hello! I use ciatim-201, please check up in my ebay shop if you wish

[@CraigMansfield]

Do you have a similar video for the black, later versions? I've just bought one, and the focus is acceptable, but a bit stiff and I'd like to clean it. My Jupiter 9 is from the 1980s, and I think it's a Pentax ring mount. It has an aperture ring, and another ring that limits/locks how much you can move the aperture (I don't know why). Have you worked on this lens? Thank you, your videos are invaluable to me.

[@RetroFotoHouse]

Hi! Yes, i know how to relubricate it, but still did not have a time to record a video tutorial. If you not yet subscribed, please sunscribe, will come one day for sure

[@samadkohi9166]

Do u have a video of cleaning the lenads?

[@samadkohi9166]

I mean the glas

[@RetroFotoHouse]

no i don't

[@mmixo]

As always, thanks for the great videos. I just got a 1956 red p with very stiff focus. I followed the video (had a hard time reassembling, but managed). I then applied the grease i have, that is supposed to be helicoid-specific (synthetic grease with PTFE) but it's just as stiff as before. Could It be the wrong kind of grease? Where can i buy the one you use? Thank you

[@RetroFotoHouse]

Hi! Try a lithium based, it will be fine. Prior to apply new grease, old one should be meticulously cleaned from threads, otherwise it will be stiff after lubrication. And do not expect jupiter-9 rangefinder version to be really smooth, as m42 SLR version, it will never be. There are too many moving parts inside. It does not fit for filmmaking purposes.

[@mmixo]

@@RetroFotoHouse thank you again for the reply. I will try to find this lithium based grease. I am using it for anamorphic shooting, so i really just need infinity. I just got infinity with m39 adapter. I thought that even been a RF version, it would work with m39-m42 then m42-MFT, but it's a macro lens with m42 adapter. It's a wonderful lens, i got one in great optical shape. Thanks again

[@danielbdbe]

hello , in case of the jupiter 50mm f/2 ,can we separate the optical block in the same way by turning it ? thanks for reply .

[@RetroFotoHouse]

yes, we can

[@ogarza3]

Can i follow this video to lubricante a jupiter 11? Anything i should look out for?

[@RetroFotoHouse]

No, jupiter-11 is different

[@DerLutzM]

Hello and thanks for sharing! I intend to buy 2 cheap Jupiter lenses (9 and 11) but on Contax RF mount. Do you have experience with these versions please?any idea if they are different constructed (beside the mount)? Inner or outer bayonet? thanks again

[@RetroFotoHouse]

Optically they are the same, only mount differs

[@MichaelRusso]

I have the Kiev Contax version and it looks a little more complex with way more screws. I am a little shy about taking it apart as it is the only one I have and I don't want it in parts and not get it back together again. That would be truly sad. :(

[@RetroFotoHouse]

Kiev Contax is completely different inside, this video is useless for your lens

[@TheWill108]

Thank you for the comprehensive look a the mechanics of these lenses. Very helpful resource. Do you you know whether disassembly of the Jupiter 11 of a similar vintage is the same as the Jupiter 9? If not, what are the differences?

[@RetroFotoHouse]

it is pretty similar in terms of thread rings design inside, but to disassemble it-is not in the similar way
