Overhaul (Top End) - Engines Which are Rated "E"
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。
当地的 Caterpillar 代理商能提供这些维修和部件。 当地的 Caterpillar 代理商可以确保这些部件在适当的技术规格范围内运行。
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,请参阅维修手册, "技术规格"模块。
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规格的零件。 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当地的 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,请咨询当地的 Caterpillar 代理商。
如果您选择不由 Caterpillar 代理商进行大修,则要注意表 1 中的建议。
