    典型示例

  1. 如有必要,将皮带轮 (8) 和螺母 (7) 安装到交流发电机 (3) 上。 使用内六角板手固定交流发电机的轴。 使用带曲柄的梅花扳手(套筒扳手)拧紧螺母 (7) 。

    注: 不同类型交流发电机的螺母尺寸不同。 确保使用螺母的正确扭矩值。

    拧紧 M16 和 M17 螺母至扭矩为 80 N·m (59 lb ft)。 拧紧 5/8 in - 18 UNF 螺母至扭矩为 102 N·m (75 lb ft)。

  1. 将交流发电机 (3) 安置在交流发电机安装支架 (4) 上。

  1. 将螺栓 (6) 安装到交流发电机 (3) 上。 将垫圈 (2) 和螺母 (1) 安装到螺栓 (6) 上。

  1. 将螺栓 (5) 安装到交流发电机 (3) 上。

  1. 拧紧螺母 (1) 和螺栓 (5) 至扭矩 22 N·m (16 lb ft)。

  1. 将配线线束组件连接到交流发电机 (3) 上。

    注: 线束组件连接不正确可能会导致交流发电机损坏或发生故障。

  1. 安装交流发电机皮带。 请参阅拆解和组装, "交流发电机皮带 - 拆卸和安装"。
