上部大修包括缸盖部件的拆卸、检查和再加工。 一些额外的部件也要更换和维修。

您的 Caterpillar代理商能提供这些服务和零部件。 您的Caterpillar 代理商可以确保这些零部件在适当的技术参数范围内运行。

下列定义对大修期间进行维修时所用术语进行了解释:

检查 - 根据 Caterpillar 零件再用性出版物中的说明来检查部件。 请参阅再用零件和修复操作指导原则, SEBF8029, "旧件再用性或修复出版物索引"。 该指导原则的编发有助于 Caterpillar 代理商和用户避免不必要的费用支出。 如果现有零部件还能使用、翻修或修理,则不要求使用新零件。 如果部件没有出现在再用性指导原则中,请参考 维修手册, "技术参数单元"。

翻新 - 部件可被翻新以便符合再用性指导原则。

更换 - 零件的使用寿命已耗尽。 零件可能在下一个保养周期前损坏。 必须更换成符合功能技术参数的零件。 替换零件可能是新件、CAT 再制造零件、翻新零件或已用过的零件。 有些磨损部件可以和您的 Caterpillar 代理商兑换成替换零件的信用。 有关您的发动机维修选项事宜,请咨询您的 Caterpillar 代理商。
