    操作已经加热的零件时要坚持戴防护手套。


  1. 如果先前拆下了飞轮齿圈,按照步骤 1.a 至 1.c 将齿圈 (5) 安装到飞轮 (1) 上。

    1. 确定轮齿 (6) 在新齿圈 (5) 上的方位。

      注: 安装飞轮时,齿圈轮齿的倒角 (6) 必须朝向起动马达。 这能确保起动马达的正确接合。

    1. 在安装之前先在烤箱中加热飞轮齿圈 (5) 至最高温度为 250 °C (482 °F)。

      注: 不要使用喷枪加热齿圈。

    1. 确保齿圈 (5) 的方位正确,然后迅速将齿圈安装到飞轮 (1) 上。

  1. 检查曲轴后油封是否泄漏。 如果观察到漏油,更换曲轴后油封。 请参阅拆解和组装, "曲轴后密封 - 拆卸"。
