Usage:

3054E 304
注: 这不是电子系统故障。

有关确定该状况原因的信息,请参阅系统操作、测试和调整手册。

可能原因

  • 交流发电机传动带

  • 交流发电机传动皮带轮

  • 交流发电机轴承

建议的措施

交流发电机传动带

  1. 检查交流发动机传动带的状况。 如果交流发电机传动带磨损或损坏,则更换传动带。 请参阅拆解和组装, "V 形皮带 - 拆卸和安装"。 确保交流发电机传动带对齐。 检查交流发电机安装支架是否断裂或磨损。 修理或更换安装支架,从而确保交流发电机传动带和交流发电机传动皮带轮对齐。

  1. 检查交流发电机传动皮带的张紧度。 如有必要,调整张紧度。 请参阅拆解和组装, "V 形皮带 - 拆卸和安装"。

交流发电机驱动皮带轮

拧松交流发电机传动皮带轮的螺母,然后将螺母拧紧至正确的扭矩。 有关正确扭矩,请参阅技术规格, "交流发电机和调节器"。

交流发电机轴承

检查交流发电机轴的端隙是否过大,并检查交流发电机轴承有无过度磨损。 交流发电机不是可维修部件。 如果轴承磨损,必须更换交流发电机。 请参阅拆解和组装, "交流发电机 - 拆解"和 拆解和组装, "交流发电机 - 组装"。
