[AT] PTO shaft grease?

[bradloomis at charter.net]

At the winery with 90% of fasteners stainless, anti-seize is a must. And the picture does it justice. And still bolts gall.

My CNC lathes at work use collets rather than chucks to hold the bar stock.  I used to have some trouble with the collet-closer, which is a tube the  collet sits inside, with an internal taper at one end that matches the taper on the collet.  The tube is pushed against the collet, the tapers bear against each other, forcing the collet to close.  Anyway, ours are old and I guess somewhat worn (although they appear pretty good) and they'd stick sometimes.  Collet won't open, stock can't feed, and the machine sits and cuts air.  I went thru several lubricants, from my favorite gear oil, to a couple different greases (a teflon, and a molybdenum) with no luck.  Never-Seize solved the problem.  We now use it routinely on all of them, all the time.  Yeah, we all know about the mess.  There are places it works where nothing else does.

Sorry, I guess "up position" wasn't very accurate. I mean I attach a
bungee around the area where the top link would attach and then around
around the PTO shaft putting it at about a 45 degree angle. My problem
is that the grease dries out and loses its lubrication properties. I
guess I could use anti-seize, but man does that stuff makes a mess. All
my equipment is stored indoors if it has a gearbox, or under a lean to
roof for things like a back blade, or box blade.
