安装步骤

注: 清洁度是一项重要的因素。 组装之前,应使用清洗剂彻底清洁所有零件。 让零件风干。 请勿使用抹布擦干零件。 棉绒可能会留在零件上,从而引发故障。 检查所有零件。 如果任何零件磨损或损坏,则应使用新零件进行更换。 尘土及其他污染物可能会损坏精密部件。 组装步骤应在清洁的工作面上进行。 务必盖上部件并采取适当保护措施。

注: 检查 O 形密封圈、垫片和密封件有无磨损或损坏。 如有必要,请更换部件。


注意

在检验、保养、测试、调整及维修发动机时,请小心确保盛接流出的液体。 在打开或拆解任何储有液体的部件之前,要准备好合适的容器收集液体。

有关适合收集和盛接卡特彼勒产品上的液体的工具和供应品,请参阅专门出版物, NENG2500, "卡特彼勒代理商工具目录"。

按照本地法规和条例处置所有液体。
