After surfacing is complete, the next step is to prepare the liners forthe proper piston size. Since we started with a 4.110 inch bore, ourfirst step is to increase the bore to 4.15250 on the Rottler F-65A,three-axis CNC machine. Once complete, the block is transferred to aSunnen CK-10, where the cylinders are honed to the final dimensions of4.160. This is accomplished using a BHJ aluminum torque plate and honingstones that range in grit from 70 to 280. The Sunnen machine continuallypumps oil during the honing process to achieve consistent honingresults. View Related Article
