建议的措施

蓄电池和/或蓄电池电缆

  1. 检查主电源开关、蓄电池接线柱和蓄电池电缆连接是否松动和有无腐蚀。 如果蓄电池电缆受到腐蚀,应拆下蓄电池电缆并清洁蓄电池电缆。 紧固任何松动的连接。

  1. 检查蓄电池。

    1. 向蓄电池充电。 请参阅专门说明书, SEHS7633, "蓄电池测试步骤"。

    1. 带载测试蓄电池。 请参阅专门说明书, SEHS9249, "6V、8V 和 12 V 铅酸蓄电池 4C-4911 蓄电池负载测试仪 的使用"。

起动马达电磁阀或起动电路

  1. 测试起动马达电磁阀的工作情况。

  1. 检查通向起动马达电磁阀的导线。

停止开关

利用 Cat ET 监视发动机的状态。 检查由于停机开关而"激活"的发动机停机事件的状态。 确定发动机停机的原因,并采取必要的措施解决停机问题。

预润滑系统(如果适用)

如果配备,检查预润滑系统是否正常工作。

盘车启用开关(如果适用)

确保盘车启用开关没有故障。

起动马达或飞轮齿圈

  1. 测试起动马达的工作情况。

  1. 检查起动马达小齿轮和飞轮齿圈是否损坏。

变速箱(如果适用)或发动机附件

  1. 确保传动系统运动自如。

  1. 拆下并检查任何可能会锁定发动机的发动机附件。

    以下列举了可能会锁定发动机的发动机附件的例子:

    • 由后齿轮总成驱动的液压泵

    • 空气压缩机

    • 发动机机油泵

    • 其它由发动机驱动的部件

气缸液锁

拆下每一个单体喷油器,检查气缸内有无液体(气缸液锁)。

注: 将燃油从缸盖内放掉。 当单体喷油器被拆下来时,燃油将会从缸盖漏入气缸内。

发动机内部故障

拆解发动机。 请参阅解体和组装手册。 检查内部部件有无下列情况:

  • 咬合

  • 部件折断

  • 部件弯曲
