While servicing my 330 planter with individual unit drives for storage I noticed that the press wheel on one row turned very very stiffly. I should note the 78 planter units have insecticide hoppers only. After disconnection the drive chain to the seed disc I determined it was the insecticide hopper drive causing the issue. I took the insecticide drive (housing & bushing/bearing) out of the frame and I could not rotate the drive by hand. With a little BP blaster and a drift I was able to get the busing out of the housing and clean them up. Question is when I put it back together what if any lubricant should I use?? Grease, heavy oil, light oil or nothing at all? I don't want to use the wrong product, have it attract dust and seize up again in the near future. If anyone wants to look up a sketch it is numbers 3 & 4 under the "Drives, Insecticide Dive, Herbicide Drive"
