检查曲轴减振器是否漏油。
- 拆下减振器。 请参考"拆解和组装"UENR3283,了解有关减振器拆卸和安装的更多信息。
- 拆下侧板 (3)。
- 将减振器内部构件 (1) 从外部构件 (2) 上分离。
注: 不要拆解减振器弹簧组件。
- 清洁减振器的所有零件。 特别注意供油和通风孔。
- 更换所有能够到的橡胶密封圈。
- 更换所有拆下的螺栓上的碟形弹簧。
- 检查 Y 形密封件磨损是否在允许范围内。 一旦拆解减振器或有泄漏迹象,就要更换密封件。 内部星形件各侧 Y 形密封的允许密封表面磨损程度为
0.2 mm (0.007 inch) 。 - 组装内部构件 (1) 和外部构件 (2)。

图 2 g02428139 - 检查弹簧叶片的磨损情况。 需要使用测量楔块。 如果没有测量楔块,需要制作一个。 参考图 2。
- 测量有无磨损。 参考图 3
- 每四个弹簧组进行一次测量。
- 将测量楔块置于弹簧叶片内端之间,让楔块接触槽底部。 测量楔块端面和槽底部必须平行。
- 用手按下或用软面锤沿着内星形槽敲打楔块。 弹簧顶针应落在两个槽面上。

楔块在弹簧叶片之间能推动的越远,内星形槽和弹簧叶片的磨损量就越大。 如果楔块能插入测量楔块的"不合格"区域,则应更换减振器。
