我部一辆翻斗车，因发动机烧瓦抱轴造成曲轴第二、三道主轴颈磨损超过使用极限，其他轴颈可以光磨到下一级大修尺寸。若整根曲轴报废、换新轴则价格太贵，造成浪费，所以我们采用对第二、三道轴颈进行电刷镀，然后光磨曲轴的工艺进行修复，效果良好，既节省了修理费用，又缩短 I dredged a dump truck, because of the engine to hug the axle caused by crankshaft second, three main journal wear over the limit, the other journal can be light grinding to the next level overhaul size.
