Several of the umpteen grease nipples on the forks of my 16H won't accept anything - oil or grease - since the bike has been sitting still for maybe 40 years. There is no sign of wear anywhere on the the machine - so I don't need to re-bush or anything as drastic. But are there any shortcuts to getting some lubrication in there where it is needed? There aren't usually - I'm well aware of that. But since the forks so operated now, it does seem a lot of work to strip the forks off and taken them entirely apart (but I don't want to haste unnecessary wear). Can they be stripped far enough to clean them up without removing them entirely? As far as I can see from the diagrams the spindles only come out with the outer link at the same time. I'm just not sure how much energy there is in the springs at the same time...
Thanks

Thanks, Peter. I'll try replacing each nipple one at a time and use a modern high pressure clip-on grease gun with oil to start with. I don't want 8000psi in case something explodes! Hydraulic bursting isn't something I want to inflict on my forks. The top forward central spindle only has one central nipple and grease only pumps out at one end - annoyingly. And with some others which are in pairs grease comes out of number 2 when I push it in to number 1.

Dave, on my girder fork bike I took the greese nipples out, soaked them in de- greaser then pumped oil through them to make sure each one was clear. Then I refitted them and pumped oil into the bushes until it pushed out the old greese. Then pumped grease into the bushes. It worked for me.
