在检查、保养、测试、调整及维修产品时，请小心确保盛接油液。 在打开任何舱室或拆卸任何含有油液的部件前，请准备好盛接液体用的适当容器。 有关适于收集和盛放 Cat 产品油液的工具和用品，请参阅专门出版物, NENG2500, "Cat 代理商维修工具目录"或专门出版物, PECJ0003, "Cat 车间用品和工具目录"。 按照本地法规和要求处置所有油液。 |
检查
正常定期维护期间，密切观察机油滤清器一般会指示滚柱轴承和轴颈轴承的状况。
应每 500 小时拆下一次检视盖并检查一下轴承的状况。
连杆轴承严重磨损或损坏时，曲轴上的匹配连杆轴颈通常也将会损坏。 可能需要拆卸和修理曲轴。 拆下带连杆轴承的曲轴和相连的连杆轴承壳。 有关信息和步骤，请参阅拆解和装配手册, "十字头 - 拆卸和安装"。
更换
工作循环和维修类型可能不同。 仅基于工作小时数来评估泵的磨损可能会有困难。 连杆轴承和滚柱轴承可能需要在大约 3000 小时后进行更换。 广泛的磨损迹象通常显示为材料剥落，导致工作表面点蚀或划伤。 轴承表面的任何剥落表示须立即更换该零件。 有关信息和步骤，请参阅拆解和装配手册, "十字头 - 拆卸和安装"。
