| Abstract:After the impact of the connecting rod on the cylinder block of one internal combustion engine, the surface of the sealing inner surface of the cooling water cavity of the cylinder sleeve and the surface of the lubrication oil nozzle flange are badly damaged and deformed, and the inner diameter and the straightness of the center line of the main bearing house exceeded the standard size. The damaged surface was welded and machined to standard. Then the Brush Plating is applied to repair the bore of the main bearing house to standard size. The straightness of the center line of the main bearing house is detected by the laser alignment system and approved meeting the standard requirement. |
