East of Broken Bow | That one would be #18. It is a sleeve bushing, not a roller bearing. The shaft is stationary, and the sprockets rotate on the shaft. #18 as suggested earlier is a retaining (snap) ring, and #19 would be the zerk. I cannot remember if the bushing is pressed onto the shaft, and the sprocket rotates on it, or if it is pressed into the sprocket, and rotates on the shaft. If I had to guess (which it is just a guess) I think it presses into the sprocket and rides on the shaft, with the shaft bieng drilled for the zerk and a grease port to lube the bushing. I'd be 90% sure that it is a standard sized bushing. | |

Which bearing is this?
