I had a search and found this

But it requires a pretty thorough dismantling...
Is there any way of adding a little more lube without this much madness? What sort of lube should i be using?
It's gone from a little stiff to really stiff in the cold, damn hard to turn earlier today - should i even keep on using it? Or am i likely to screw it up?
Sorry if this is a dumb question answered by the link above or by "get it CLAed"
Cheers

Ouch. Pretty complicated, but seems straight-forward if you take care.
I find that this kind of operation doesn't tolerate short-cuts (e.g. like trying to drop in a drop of oil on the thread, if you can even get access to it).
Best to reserve some time, set up a clean work-table with good lighting and good tools, and do it carefully.
Good luck

yeaaah... mine doesn't have those screws.
I agree that it would be nice to be able to pop a little lube in, but i guess if it can dribble in, it can dribble out and onto the sensor huh?
Thanks for the replies!

Well, you wouldn't dribble so much in, that it would flow out.
But you would need to dribble it into the right place.
If you could get access, a curved hypodermic syringe could work wonders.
But this one looks like multiple helixes and sliding rings. Tricky to get access to all of them.

Take it to a technician. Better to have a pro do it. Could cost you a lot more down the road if you mess up!

the golden brass thingy i focused so all of it would be out..
then used an eyedrop with olive oil and its smooth as butter..
Sometimes the oil looks like its close to the outer glass so i wipe with alcohol like once a month.

Which is why focus helicoids should be lubricated with grease.

Cris,
I've done that many times, and my advice is to leave it alone.
Reasons:
1) VC used loctite on the set screws.
2) It's a nightmare to reassemble.
3) Relubing the lens won't help.
You must disassemble the lens twice. First, you must use extra fine grinding and lapping compound paist instead of lub. Disassemble again, clean and relube.
Result - smooth focussing but the lens will start to wobble.

Before thinking about greasing it, slacken off all the screws that attach the bayonet flange to the lens body. Then very gradually tighten them up again, opposite to opposite, until they are fully tight. Doing that sorted out the tight notchy focusing on my CV 40mm.
