    典型示例

  1. 如果先前拆下了齿圈,按照步骤 1.a 至 1.c 将齿圈 (3) 安装到飞轮 (2) 上。

    1. 确定新齿圈的方向,以将齿圈正确安装到飞轮上。

      注: 安装飞轮时齿轮轮齿 (Y) 的斜面侧必须朝向起动马达,以确保起动马达的正确接合。

    2. 安装之前先在烤箱中加热齿圈 (3) 至最高温度 150°C (302°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 (2) 上。

  2. 彻底清洗飞轮壳体。 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, "曲轴后油封 - 拆卸和安装"。

  3. 将工具 (B) 安装到曲轴上的 (X) 部位。

  4. 将工具 (A) 和适当的起吊设备安装在飞轮 (2) 上。 飞轮的重量约为 42 kg (93 lb)

  5. 在配有滚销的三缸发动机上,确保滚销安装在曲轴上。 确保滚销未损坏。 将飞轮中的孔与曲轴中的滚销对准。

    将飞轮 (2) 定位到工具 (B) 上。

  6. 安装螺栓 (1) 并用手拧紧。

  7. 拆下工具 (B),然后安装两个其余的螺栓 (1)。

  8. 用一个合适的工具,以防止飞轮 (2) 转动。 拧紧螺栓 (1) 至扭矩为 74 N·m (54 lb ft)

  9. 将工具 (A) 和起吊设备从飞轮上拆下。

结束:

  1. 安装电起动马达。 请参阅拆解和组装, "电起动马达 - 拆卸和安装"。
