Engine Crankcase Breather - Clean
如果没有定期保养曲轴箱呼吸器,曲轴箱呼吸器将会堵塞。 被堵塞的曲轴箱呼吸器将导致曲轴箱压力过高,从而导致发动机停车。 曲轴密封泄漏可能发生。
注: 有关曲轴箱压力技术规格,参考故障诊断与排除手册, SENR6510。
注: 可能需要使用一个平台以便接近发动机曲轴箱呼吸器。
发动机停机时进行该项保养。

- 拧松固定夹 (5)。 拧松管卡箍 (3)。 拆下呼吸器组件 (1) 和 O 型密封圈 (4)。
- 用干净的、不易燃的溶剂清洗呼吸器滤芯。 检查三通管 (2) 是否因振动导致裂缝。 如果发现裂缝,用新的三通管更换旧的三通管。
- 安装新 O 形密封圈 (4)。
- 安装前,晾干呼吸器滤芯。 在原来的位置上安装呼吸器组件。 用干净的发动机机油或凡士林涂覆橡胶零件。 根据发动机的技术规格手册,拧紧固定夹和管夹。
