安装步骤

表 1
所需工具    
工具     零件号     零件名称     数量    
A     6V-4003     定位工具     1    
2N-5006 螺栓     2    
B     6V-4977     安装工具     1    
9S-8858 螺母     1    


注意

只要从耐磨套筒上拆下曲轴密封件,就必须安装一套新的耐磨套筒和密封件。

安装用过的密封件将造成泄漏。



注意

如果在安装时需要将曲轴密封件和耐磨套筒分开,则很难保证密封性。 请更换一套新的曲轴密封件和耐磨套筒。


注: 前后密封件不可互换,前后耐磨套筒也不可互换。 密封件的密封唇口上有凹槽,这些凹槽可在曲轴转动时,引导机油流回曲轴箱。 交换使用前后密封件会使机油流出曲轴箱。
