The easy way to clean and re-lube a Carl Zeiss Pancolar 1.8

[eddieitman]

OK so i had a Pancolar F1.8 that would hardly move, and after posting on the bargain corner that i fixed mine rather easily with just a bit of lighter fluid and no major disassembly a few people expressed interest, so here is a guide
What you will need
Lighter Fluid
Silicone Grease (mine came from Lidl)
Cotton Buds.
A flat head screwdriver.
10 minutes of time.
Patience.
I take no responsibility should you damage your lens, i managed to do mine with no repercussions.


#1 What you will need for cleaning and re-lubbing

#2 after removing the rear section of the lens

#3 notice the position of the aperture at F1.8 before removing the aperture ring.

#4 With the lens at infinity make sure to remove all excess dried up grease use a dry cotton bud

#5 clean this are as well

#6 notice the hellicoid being cleaned

#7 Helicoid all clean now

#8 Add a few tiny drops of lighter fluid to the hellicoid, be very sparing only one drop should do it dont soak the lens then start to twist the focus to work it in, you should notice that it will produce a lot of black gunk once it has worked in make sure to remove as much as possible

#9 Black Gunk we talked about remove this with cotton buds

#10 once cleaned apply a tiny amount of silicone lube (be careful spraying this only a half press should do) and twist and turn the focus again remove any residual black gunk and re-assemble lens


Here is a video showing the smooth focus now i hope this helps somebody

So as you can see no major dismantling, or scary bits that fall off, a simple and easy way to repair the lens
P.S i have used silicone lube for years in my car door windows, and had no detriment as to it clogging or getting stiff

Very well done Eddie. Thanks for taking the time and effort to do this for us.

Could I make a small suggestion? Instead of spraying the grease directly on the helicoil thread, it would be better to spray and little into a shallow container, perhaps the lid of the can, and use a small artist's paintbrush to apply it.

My Pancolar has sticky blades. You wouldn't mind doing a similar guide to cleaning them for me, would you?

Cheers for that!

I'll be doing this to the Tessar once it arrives. I daresay the location will be slightly different, but the principle is the same.

Hi Came across your post & thought I would have a go at re lubing the one I have all seems Ok but I have a spring left over ,can anyone point me as to where it fits.
I also presume that I have the spring for the diaphragm pin correct as well?




Thanks

Thanks for the quick response I seem to be having trouble posting pics or even a flickr link as I would show the spring in question.
any tips ?
regards
James

[Jamesb101]

You can see pics here of the 'spare' spring & the base of the lens,although it does seem to differ from yours

Hey,

I just got a Jena 50mm f2.8 too and I just did everything I could to get it unstuck without success.

Right now, the lens is almost fully disassembled on my desk, I can clean the male focusing screw and grease it properly.

I followed this http://oomz.net/tessar/ but my lens isn't the from same year make. Mine looks just like the one on this thread.

My question is : What should be movie with the focusing ring ?

The whole assembly with he aperture scale (the one with the red line, number 5 on the website)... doesn't make sens to me
or
The outer helicoil thread should rotate freely INSIDE this assembly (number 5)...because that's where mine won't move an inch!


We can see on the website part number 5 at the bottom of the page with all the parts... we see the "outer" helicoil atached to number 5.. are those 2 thing fixed together??

And since the focusing ring shouldn't move with the red line... I'm confused

I'll try soaking the focusing ring + outer helicoil in alcohol overnight.


I found a "stock" picture of my lens model : http://www.filterfantastic.co.uk/bayimages/3009%20Bags/BG5Q9352.jpg

Let me know if you have any idea, I'll try to post a picture tomorow... it should help a lot.

[eddieitman]

Have you tried getting to the hellicoid from the front? Use a sink plug to unscrew the name tag once removed there should be three screws to remove the front half the lens and we should then be able to see the hellicoid to remove the glass and access the blades use a tool similiar to what i have on the 1st pic its an o ring seperator purchased from any good hardware store mine cost around £5 loks like a compass one the glass is removed you can access the blades and clean with lighter fluid

[Andreq]

The inner helicoil is "out", thats not my problem.


On this picture, is the Helicoil (outer) fixed to this whole assembly (part #5) ?

Mine is... and I don't see how the lens can focus that way :S

edit : Doesn't make sens at all using this picture... I'll try to mspaint something at work... go2go now -_-

edit 2 :



The blue part is out.

The red part is the "aperture assembly" (part number 5)

The green part is the focusing whell.


Is the green supposed to be stuck to the red ? The only way I can separate them is when I unscrew the focusing wheel retaining screw (a big ~1.5inch screw/ring with 2 slot for a spanner wrench). Removing this ring, the focusing wheel move freely... but doesn't move anything... thus doesn't focus :S

Had to use picasa since our proxy block the traditional upload -_-

[Andreq]

Anyone have a diagram of how a focus wheel work? I'm really confused with this lens... the assembly doesn't make sens. It's as if the focus wheel was attached to the lens mount (when fully assembled). Doesn't make sens, the focus ring can't turn if the mount doesn't turn with it :S
