Nikon 50mm: lubricate focus helical?

[removedacct1]

I have a 1980s Nikon 50mm F1.4 lens on my FM2 that desperately needs the focusing helical cleaned and lubricated; its dry as a bone. I've stripped and restored many Kodak Retina models so I am familiar with how to clean and lubricate the helical in one of those, but I haven't any idea how to get into the Nikon lens to perform the task.

Anyone have experience doing this, and can you instruct me, please? I don't need to strip the lens down completely, I just need to get some lubricant into the helical. Thanks.

You'd be better off doing the entire strip down and relube. The videos above make it easier than you think.

That's awesome, thank you very much!

You are welcome!

I added a link above on working with Helicoils from Richard's site. You may already know this stuff, but wanted to be sure you saw it anyway.

I am about to tear apart my bargain Nikkor-P 105 f2.0 and relube it after watching both Kenneth's and Richard's tutorials.

once you take off the mount, extend the focus to the closest distance--in many nikon lenses this will expose quite a chunk of the helicoid... a small pile of q-tips, a few toothpicks, some patience, and you might be able to get decent results without stripping the lens... i did this for 50/1.8, 55/2.8, 28/2, and a couple more... still use them, never an issue in many years
