I replaced the cylinders because of defective welds, so they are new. My concern is that the scored pin might cause a problem with the new bushing.
One thing I notice when greasing machines is that often grease pours out of one end of the pin, and no matter how much grease I add nothing flows out of the other end. When this happens I wonder if grease, for whatever reason, is only getting to one side.
