My Ford 202 disc is blue. I unbolted 2 bearing caps and dropped one gang to look at bearings, as I thought they felt sloppie and pressing against top caps. To my surprise they were "steel on steel, with round knob in center, for side pressure control". This is far better than our previous "dearborn disc, which had wood bearings". I put the gang back on as there apeared tobe more use yet (if greased every day, of use). The only design problem, is dirt can get in bearings, especially in dead furrow, on plowed ground and mix with grease, therby reducing its life. This can be judged by looking "how thin the top cap is, against gang spool". Since mine appeared to have quite a bit of life in the bearing wear, I plan on a type of dirt seal on each side of the bearing caps, to the edge of the spool flange (where spool touches disc blade). I have purchased 3/8 nylon rope (2 each side), which I plan on cuting to fit around spool, and melt the ends together. I then was going to use "Fiberglass" to fasten over the ropes and caps, to hold the rope from turning. I feel this would "reduce the area fo dirt, to enter bearing, and therby extend the grease life, and consequent bearing life. Just have to "find a round "TOOIT" yet.
