120K Motor Grader Caterpillar


Crankshaft Vibration Damper - Inspect

Usage:

120K JAP
振動阻尼器損壞或故障會導致扭轉振動的增加。 這些振動會造成曲軸和其他引擎組件損壞。 退化的振動阻尼器會造成在速度範圍內多點的齒輪系噪音過大。


插圖 1g01466327

Caterpillar 建議您基於以下原因更換振動阻尼器 (1):

  • 引擎曾經因為曲軸損壞而故障。

  • S·O·S 分析偵測到曲軸前軸承磨損。

  • S·O·S 分析偵測到非因缺少機油造成的齒輪傳動系統大量磨損。

  • 檢查時偵測到液體洩漏。

  • 殼體損壞。

請參閱拆解及組裝, "阻尼器和曲軸滑輪",以瞭解取下及安裝阻尼器的程序。

如果並未出現上述情況,同時減震器也沒有損壞,則可再次使用減震器。

附註請諮詢 Caterpillar 代理商以瞭解進一步資訊。
