Cylinder liners of both 4-stroke and 2-stroke engines show signs of wear and tear after extended use, regardless of the latest advances in lubricating oil and liner casting technologies. What's not quite so obvious is that when doing the consequent engine overhauls or engine repairs that involve cylinders, it is predictable that the liners will have to be deglazed and crosshatched. For cylinder deglazing jobs (plateauing as well) one industry standard tool is the compact, portable ball hone from Brush Research Manufacturing (BRM), who recently announced that its Flex-Hone® tool was available for ‘big bore’ marine diesel engines up to 40-inches in diameter.
