May I tell you a dealer point. You were more than likely in a John Deere store. Not a John Deere dealership. If you don't see a bunch of tractors and new or used equipment around your not at the right place. I have a tube here that I will send you if you can't get it. Do NOT use 00, if it runs out of a bottle it's not what you want. I have used JD corn head grease for 50 years and never a problem with leaks or wear in all my vehicles. I feel a little guilty, one of my 3100's has been using a mix of moly and JD/ch grease (10% moly), for 45 years. You would think I would replace the seal. However if I did I would have to change it out again in several years, one less grease/oil spot. I may have misunderstood, were you folks talking about 00 in a bottle or tube? Doc.

I have been considering this service as well on my 3100. Question:
My steering box has the side cover; but I've noticed that on the bottom, it has what looks like a large 2" nut with a slot in the middle that looks like its for a large flat screwdriver. Does this unscrew? I would need to use my pipe wrench on it, but not sure I can squeeze in that small area. I would like to do a flush; jack up the front end, several fills/turns/flushes with diesel, and then a tube of new Chevron 00 grease that I got from a fellow Stovebolter here. Any suggestions?

That big nut on the bottom is the adjustment for the worm bearings. It does unscrew, but you would then need to do the complete adjustment on the steering gear. First the worm bearing preload adjustment, and then the sector shaft adjustment. Check the Service Manual [chevy.oldcarmanualproject.com] for the procedure.
