K so doing some seasonal work on the 38 alliance we bought this unit used. And was unsure what it's been through. So going through it after two summers of use pulled the swing lever and splines hit the floor.... ok swing tube is finished. So looking at the cylinders with the s tube out of the way there is a buildup of concrete on the top of the reduction rings were the cylinder meets the reduction rings. This unit always gets a good washing after every job. Could this be a sign on how worn those cylinders are?
