  1. 如果已卸下飞轮齿圈,遵循步骤 1.a 至步骤 1.c 以将新齿圈安装到飞轮上。

    1. 确定新齿圈 (3) 上齿 (4) 的方向。

      注: 在安装飞轮时齿圈轮齿的倒角侧必须朝向起动马达。 这将确保起动马达的正确接合。

    2. 在安装之前,先在烤箱中加热飞轮齿圈 (3) 至最高温度 250 °C (482 °F)

      注: 不要使用喷枪加热齿圈。

    3. 确保齿圈 (3) 的方向正确,并迅速将齿圈安装到飞轮 (1) 上。

  2. 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"和拆解和组装, "曲轴后密封-安装"了解正确的步骤。
