曲轴箱呼吸器可防止曲轴箱内产生压力。 曲轴箱内产生烟尘中的部分机油被呼吸器滤芯收集。 烟尘排入大气中。

如果曲轴箱呼吸器未定期保养,就会逐渐堵塞。 曲轴箱呼吸器堵塞将使曲轴箱压力过高,这可能造成曲轴密封渗漏。 可以清洗呼吸器滤芯。


注意

保持所有零件清洁无杂质。

杂质会造成快速磨损和缩短部件寿命。



注意

在检验、保养、测试、调整及维修产品时,必须小心以确保收集好排放出的油液。 在打开任何舱室或拆解任何储有液体的零件之前,要准备好合适的容器收集流出液体。

有关收集和盛接卡特彼勒产品的液体的合适工具和用品,请参阅专门出版物, NENG2500, "卡特彼勒代理商维修工具目录"。

按照本地法规和指令处理所有液体。

    (4) 呼吸器

  1. 松开卡箍 (2) 。 将夹箍滑到管 (3) 上。

  1. 拆下螺栓 (1) 和挡圈。

  1. 拆下呼吸器。

  1. 用干净的、不易燃的溶剂清洗呼吸器滤芯。

    把呼吸器倒置,以便检验呼吸器滤芯的状况。 如果清洗后呼吸器仍然不干净,则废弃该呼吸器,换用新的呼吸器。 不要试图分解呼吸器。

    安装前,晾干呼吸器滤芯。

  1. 呼吸器有一个橡胶密封垫,也是装置的一个零件。 将清洁的发动机机油涂在密封垫上。

  1. 重新安装呼吸器 (4) 、挡圈和螺栓 (1) 。 关于正确扭矩,请参考维修手册, "技术参数"。

  1. 将软管 (3) 放到呼吸器上。 将卡箍滑动适当位置并拧紧。 关于正确扭矩,请参考维修手册, "技术参数"。
